In a recent year, a hospital had 4164 births. Find the mean number of births per day, then use that result and the
Poison distribution to find the probability that in a day, there are 13 births. Does it appear likely that on any given day,
there will be exactly 13 births?
Answers
Mean number of births per day ≈ 11.41.The probability of having exactly 13 births in a day,is approximately 11.41, is about 11.79%.. No, it doesnot appear likely that on any given day,there will be exactly 13 births.
Define probability?Probability can be defined as the ratio of favourable outcome to the total number of outcome.
What is Poisson distribution?A Poisson distribution is a discrete probability distribution. The chance of an event occurring a specific number of times (k) during a specific time or space period is provided by the Poisson distribution. The mean number of occurrences, denoted by the letter "lambda," is the single parameter of the Poisson distribution.
To find the mean number of births per day, we divide the total number of births in a year (4164) by the number of days in a year. Assuming a year has 365 days, the mean number of births per day would be:
Mean number of births per day = Total number of births in a year / Number of days in a year
Mean number of births per day = 4164 / 365
Mean number of births per day ≈ 11.41
Now, we can use the Poisson distribution to find the probability of having exactly 13 births in a day, given that the mean number of births per day is approximately 11.41.
The Poisson distribution is used to model the number of events occurring in a fixed interval of time or space, when the events are rare and random, and the average rate of occurrence is known.
The probability mass function (PMF) of the Poisson distribution is given by the formula:
P(X=k) = ( [tex]lambda^{k}[/tex]×e^(-λ)) / k!)
Where:
λ is the average rate of occurrence (mean) of events in the given interval
e=2.71828
k is the number of events for which we want to find the probability
k! is the factorial of k (k factorial)
In this case, the average rate of occurrence (mean) of births per day is approximately 11.41 (calculated in the previous step). So, we can plug in the values into the Poisson PMF formula:
P(X=13) = (λ¹³ ×e^(-λ)) / 13!
P(X=13) = (11.41¹³ × e^(-11.41)) / 13!
Calculating this value using a calculator or software, we can find that:
P(X=13) ≈ 0.1179 or 11.79%
So, the probability of having exactly 13 births in a day, given the mean number of births per day is approximately 11.41, is about 11.79%.
Based on this probability, it appears unlikely that on any given day there will be exactly 13 births, as the probability is relatively low. However, it is important to note that the Poisson distribution assumes that the events are rare and random, and there may be other factors that can affect the actual number of births in a day, such as seasonality, day of the week, and other external factors. Therefore, further analysis and consideration of other factors may be needed to make a more accurate assessment of the likelihood of exactly 13 births occurring in a day at a specific hospital.

Answers
Answer:
To find the distance between a point and a line in a plane, we can use the formula:
distance = |Ax + By + C| / √(A^2 + B^2)
where A, B, and C are the coefficients of the general form of the line equation (Ax + By + C = 0), and (x,y) are the coordinates of the point.
First, we need to rewrite the given line equation in the standard form (y = mx + b):
2x - 3y = -2
-3y = -2x - 2
y = (2/3)x + 2/3
Now we can identify the slope (m) and y-intercept (b) of the line:
m = 2/3
b = 2/3
Next, we can find the equation of the perpendicular line that passes through the point (1,2), since the distance between the point and the line will be the length of the segment connecting the point to the intersection of these two lines. The slope of a line perpendicular to a line with slope m is -1/m, so the equation of the perpendicular line passing through (1,2) is:
y - 2 = (-3/2)(x - 1)
y = (-3/2)x + (7/2)
Now we need to find the intersection of the two lines by solving the system of equations:
y = (2/3)x + 2/3
y = (-3/2)x + (7/2)
(-3/2)x + (7/2) = (2/3)x + 2/3
(-13/6)x = -5/6
x = 5/13
y = (2/3)(5/13) + 2/3
y = 11/13
So the intersection point of the two lines is (5/13, 11/13). Now we can use the distance formula to find the distance between this point and the given point (1,2):
distance = √[(5/13 - 1)^2 + (11/13 - 2)^2]
distance = √[(36/169) + (25/169)]
distance = √(61/169)
distance = √61/13
The closest answer choice is (A) √13, but the simplified expression is actually √61/13. Therefore, none of the answer choices provided are completely accurate.

A pole that is 3.3 m tall casts a shadow that is 1.71 m long. At the same time, a nearby building casts a shadow that is 48.25 m long. How tall is the building? Round your answer to the nearest meter.
Answers
The height of the building is given by h = 93.5 m
Given data ,
Let the proportion be represented as A
Now , the value of A is
The height of the pole is 3.3 meters and its shadow is 1.71 meters long. We can set up a proportion to find the height of the building:
Height of pole / Length of pole's shadow = Height of building / Length of building's shadow
3.3 m / 1.71 m = x / 48.25 m
Now we can cross-multiply and solve for "x":
3.3 m * 48.25 m = 1.71 m * x
159.825 m² = 1.71 m * x
x = 159.825 m² / 1.71 m
x ≈ 93.5 m

When Caroline runs the 400 meter dash, her finishing times are normally distributed with a mean of 68 seconds and a standard deviation of 1.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 99.7% of her finishing times in the 400 meter race.
Answers
The empirical rule to determine the interval middle 99.7% of Caroline's finishing times in the 400 meter race is 63.5 seconds to 72.5 seconds
Given data ,
The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution:
Approximately 68% of the data falls within one standard deviation of the mean.
Approximately 95% of the data falls within two standard deviations of the mean.
Approximately 99.7% of the data falls within three standard deviations of the mean.
Since the middle 99.7% of data falls within three standard deviations of the mean, we can calculate the upper and lower limits of this interval as follows:
Lower limit = Mean - (3 x Standard Deviation)
Upper limit = Mean + (3 x Standard Deviation)
Plugging in the values for mean and standard deviation:
Lower limit = 68 - (3 x 1.5) = 68 - 4.5 = 63.5 seconds
Upper limit = 68 + (3 x 1.5) = 68 + 4.5 = 72.5 seconds
Hence , the interval of times that represents the middle 99.7% of Caroline's finishing times in the 400 meter race is 63.5 seconds to 72.5 seconds

What is survey?
The conclusion that about 8.6% of the students in the school have a January birthday is not necessarily valid based on the information provided.
The sample size of the survey is too small (only 3 students with January birthdays) and limited to one math class, so it may not be representative of the whole school population. Additionally, the sample is not randomly selected, which introduces the possibility of selection bias.
Therefore, it is not appropriate to generalize the findings of the survey to the entire school population. A more reliable way to determine the percentage of students with a January birthday would be to collect data from a larger, randomly selected sample of students across the entire school population.

What is the value of the angle in the parallelogram?A quadrilateral has two pairs of sides are parallel to each and the four angles at the vertices are not equal to the right angle, and then the quadrilateral is called a parallelogram. Also, the opposite sides are equal in length.
The key properties of angles of a parallelogram are:
- If one angle of a parallelogram is a right angle, then all the angles are right angles
- Opposite angles of a parallelogram are equal (or congruent)
- Consecutive angles are supplementary angles to each other (that means they add up to 180 degrees)
Consecutive angles are supplementary and as such:
85 + 8x - 1 = 180
8x = 181 - 85
8x = 96
x = 96/8

Find the standard form of the equation for the circle with the following properties.
Endpoints of a diameter are (−6,−1) and (−8,−11)
Answers
Standard form of the equation for the circle with the following properties is (x + 7)² + (y + 6)²= 104.
What is diameter?A line segment through the center of a circle with its ends on the circle's circumference. Its value is twice of the radius.
Define equation?An equation is a mathematical statement that asserts the equality between two expressions, typically containing one or more variables. It consists of two sides separated by an equals sign (=), indicating that the expressions on both sides have the same value. Equations are used to describe relationships, solve problems, and make predictions in various branches of mathematics, science, engineering, and other fields. They can be linear or nonlinear, and may involve arithmetic, algebraic, trigonometric, exponential, or other mathematical operations. Solving an equation involves finding the values of the variables that make the equation true.
To find the standard form of the equation for a circle, we can start by finding the center and radius of the circle using the given endpoints of a diameter.
The center of the circle is the midpoint of the diameter, which can be found by averaging the coordinates of the two endpoints. Let's denote the coordinates of the endpoints of the diameter as (x1, y1) and (x2, y2) respectively.
In this case, the coordinates of the endpoints are (x1, y1) = (-6, -1) and (x2, y2) = (-8, -11). Using the midpoint formula, we can find the center of the circle:
Center = ((x1 + x2)/2, (y1 + y2)/2)
Plugging in the values, we get:
Center = ((-6 + (-8))/2, (-1 + (-11))/2)
Center = ((-14)/2, (-12)/2)
Center = (-7, -6)
So, the center of the circle is (-7, -6).
The radius of the circle is half the length of the diameter, which can be found using the distance formula between the two endpoints of the diameter. Let's denote the distance between the endpoints as d.
The distance formula is given by:
d = sqrt((x2 - x1)² + (y2 - y1)²)
Plugging in the values, we get:
d = sqrt((-8 - (-6))² + (-11 - (-1))²)
d = sqrt((-2)² + (-10)²)
d = sqrt(4 + 100)
d = sqrt(104)
So, the radius of the circle is sqrt(104).
Now that we have the center and radius of the circle, we can write the standard form of the equation of the circle as:
(x - h)² + (y - k)²= r²
where (h, k) is the center of the circle and r is the radius of the circle.
Plugging in the values, we get:
(x - (-7))² + (y - (-6))² = (sqrt(104))²
(x + 7)² + (y + 6)²= 104
So, the standard form of the equation for the circle with endpoints of a diameter at (-6, -1) and (-8, -11) is (x + 7)² + (y + 6)² = 104

12. The measures of alternate exterior angles are
Answers
Answer:
The same, Congruent
Step-by-step explanation:
The measures of alternate exterior angles are equal when two parallel lines are intersected by a transversal line. That is, if we have two parallel lines l and m intersected by a transversal line t, then the alternate exterior angles are congruent, which means that they have the same measure. More formally, if angle 1 and angle 2 are alternate exterior angles, then:
angle 1 = angle 2
The reason for this is that when the parallel lines are intersected by the transversal line, they form a Z-shape pattern, and the alternate exterior angles are located on opposite sides of the transversal line, but outside of the two parallel lines. The angles are congruent because they are formed by a pair of corresponding angles and a pair of vertical angles.

Tom and Philip were given the graph of a linear function and asked to find the slope. Tom says that the slope is 12 while Philip says that the slope is 2.
Which reason correctly justifies Tom's answer?
Answers
Without seeing the graph of the linear function, it is impossible to determine if Tom's answer of 12 is correct or incorrect. However, it is important to understand the concept of slope and how it is calculated for a linear function.
The slope of a linear function represents the rate at which the y-coordinate changes for each unit increase in the x-coordinate. In other words, it measures the steepness of the line. Mathematically, the slope of a line is defined as the ratio of the change in the y-coordinate to the change in the x-coordinate between any two points on the line.
To calculate the slope of a line given its graph, one can choose any two points on the line and find the difference in their y-coordinates and x-coordinates. The slope is then the ratio of the change in y-coordinates to the change in x-coordinates. This can be expressed as:
slope = (change in y-coordinate) / (change in x-coordinate)
Now, if Tom has correctly identified two points on the line and calculated the difference in their y-coordinates and x-coordinates, and if he has obtained a ratio of 12 for the change in y-coordinate to the change in x-coordinate, then his answer of 12 for the slope would be correct.
However, it is also possible that Tom made an error in his calculation, or that he misread the graph, and obtained an incorrect answer. Therefore, it would be necessary to verify his calculations by checking the points he used and the formula he applied.
In conclusion, without further information about the graph of the linear function and the points chosen by Tom to calculate the slope, it is impossible to determine if his answer of 12 is correct or incorrect.

Using a table, find the range of the function for the given domain:
f(x)=2x+7 with domain: x = {2, 3, 5, 9}
A. y = {9, 10, 12, 16}
B. y = {11, 13, 17, 25}
C. y = {4, 6, 10, 18}
D. y = {-11, -13, -17, -25}
Answers
The range of the function is y = {11, 13, 17, 25}.
What is range of function?In mathematics, the range of a function refers to the set of all possible output values that the function can produce when given a set of input values. It is also known as the image of the function. The range of a function can be found by evaluating the function for all possible input values, or by analyzing the properties of the function.
According to given information:To find the range of the function, we need to substitute each value of the domain into the function and record the corresponding output values.
For x = 2, f(2) = 2(2) + 7 = 11.
For x = 3, f(3) = 2(3) + 7 = 13.
For x = 5, f(5) = 2(5) + 7 = 17.
For x = 9, f(9) = 2(9) + 7 = 25.
Therefore, the range of the function is y = {11, 13, 17, 25}.
The answer is A. y = {9, 10, 12, 16} is not the correct range for this function with the given domain.

Turner helped his grandfather build a raised garden bed for Tanner’s grandmother. The bed is shaped like a rectangular prism that is 4 1/2 feet wide and a half of a foot tall. Turner and his grandfather use 18 bags of topsoil, each containing three force of a cubic foot, to feel the bed completely. How long is the garden?
Answers
The length of the garden containing the soil is L = 24 feet
Given data ,
Volume = Length x Width x Height
Width = 4 1/2 feet
Height = 1/2 foot
Total volume of topsoil used = 18 bags x 3 cubic feet/bag = 54 cubic feet
So , the length of the garden is
54 = Length x 4 1/2 x 1/2
On simplifying , we get
54 = Length x 9/2 x 1/2
Now, let's simplify the right-hand side by multiplying the numerator and denominator by 2
54 / (9/2 x 1/2) = The length of the garden
The length of the garden = 54 /9 x 4
The length of the garden = 6 x 4
The length of the garden = 24 feet
Hence , the length of the garden bed is 24 feet
