Consider the probability that exactly 91
out of 153
registered voters will vote in the presidential election. Assume the probability that a given registered voter will vote in the presidential election is 59%
.
Step-by-step explanation:
We can use the binomial distribution to compute the probability that exactly 91 out of 153 registered voters will vote in the presidential election, assuming that the probability that any given registered voter will vote in the presidential election is 59%.
The probability mass function of the binomial distribution is:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where:
- n is the number of trials (in this case, the number of registered voters)
- k is the number of successes (in this case, the number of registered voters who will vote in the election)
- p is the probability of success on any individual trial (in this case, the probability that a given registered voter will vote in the election)
Using this formula, we can calculate:
P(exactly 91 out of 153 voters will vote) = (153 choose 91) * 0.59^91 * (1 - 0.59)^(153 - 91)
= 0.037
Therefore, the probability that exactly 91 out of 153 registered voters will vote in the presidential election is approximately 0.037, or about 3.7%.

Given: A rectangular pyramid with a base of dimensions 7 centimeters by 5 centimeters. The two large triangular faces have a height of 7.6 centimeters. The two small triangular faces have a height of 8 centimeters.
We have to find the surface area of the pyramid.
The rectangular base of the pyramid has a length of 7 centimeters and a width of 5 centimeters, so the area of the rectangular base is 35 cm².
The two large triangular faces have a height of 7.6 centimeters, so the area of each of these faces can be calculated as:
= (1/2)×7×7.6
= 26.6 cm²
Similarly, the two small triangular faces have a height of 8 centimeters, so the area of each of these faces can be calculated as:
= (1/2)×5×8
= 20cm²
The total surface area of the rectangular pyramid is:
= 35cm² + 2×26.6 cm² + 2×20 cm²
= 128.2cm²

What happens to a consistent slope when the y value starts to decrease and the x value remains the same over time?
A. Y decreases and X decreases
B. Y decreases and X increases
C. Y increases and X increases
D. Y increases and X decreases
Answer:
If the y value decreases while the x value remains the same over time, then the correct answer would be A. Y decreases and X decreases.
Step-by-step explanation:
Sure! A slope is a measure of the steepness of a line. It is calculated by dividing the change in the y-coordinates (rise) by the change in the x-coordinates (run) between two points on a line. The formula for slope is m = (y2 - y1) / (x2 - x1).
In your question, if the y value decreases while the x value remains the same over time, it means that the change in y-coordinates (rise) is negative while the change in x-coordinates (run) is zero. This results in a vertical line with an undefined slope. Therefore, the correct answer would be A. Y decreases and X decreases.

How do we find Probability?
The measurement through which we find the likelihood of an event to occur is called probability. We cannot predict a lot of events with total certainty. And thus, the chance of a event to occur (i.e. how likely they re going to happen) can be predicted using probability.
Probability of any event to happen can be find as: No of favorable outcomes/Total number of outcomes.
Here,
The total no of outcomes = 1,2,3,4,5,6,7,8,9,10
No of favorable outcomes ={2,3,4,6,8,9,10} = 7
Therefore, P(E) = 7/10

The average child in elementary school brings home 13 pieces of paper to show their parents each week. Students at Little Kids Elementary School are in a program that is supposed to be more focused on digital work than paperwork. In one week, five students brought home to following number of papers: 14, 12, 18, 8, 11
Conduct the steps of hypothesis testing to determine whether there is a different amount of papers brought home by the kids at Little Kids Elementary School compared to normal.
The steps of "hypothesis-testing" for papers bought home are stating the Null and Alternate Hypothesis, find level-of-significance, collecting data, determining p-value, and making decision.
The "Hypothesis-Testing" is defined as a statistical method used to make inferences about a population based on a sample of data. It involves making a assumption about a population parameter (such as its mean or proportion) and then collecting data to test whether the hypothesis is likely to be true or false.
The steps of hypothesis testing are:
Step 1: State the "Null-Hypothesis"
The null hypothesis (H₀) is = average number of papers brought home by the kids at Little Kids Elementary School is the same as the average for the general population, which is 13.
⇒ H₀: µ = 13,
Step 2: State the alternative hypothesis
The "Alternative-Hypothesis" (Hₐ) is = average number of papers brought home by the kids at Little Kids Elementary School is different from 13.
⇒ Hₐ: µ ≠ 13,
Step 3: Determine the level of significance
Let "significance-level" be "α = 0.05". This means we accept a 5% chance of making a "Type I Error"
Step 4: Collect the data and calculate test-statistic
The sample mean of the number of papers brought home by the kids at Little Kids Elementary School is:
⇒ x' = (14 + 12 + 18 + 8 + 11)/5 = 12.6,
The sample standard deviation is:
⇒ s = √[((14-12.6)² + (12-12.6)² + (18-12.6)² + (8-12.6)² + (11-12.6)²)/4] ≈ 3.71
The "test-statistic" ⇒ t = (x' - µ)/(s/√n);
where n = sample size = (5),
⇒ t = (12.6 - 13)/(3.57/√5) = -0.25,
Step 5: Determine of "p-value",
The "degrees-of-freedom" = 4, ..because 5 - 1 = 4,
We know that "p-value" for t = -0.63 with 4 "degrees-of-freedom" is approximately 0.8103.
Step 6: Making decision and interpreting results
The p-value is 0.8103 which is greater than "significance-level" of (0.05),
So we fail to reject the null hypothesis. and say that there is not enough evidence to conclude that the average number of papers brought home by the kids at Little Kids Elementary School is different from the population mean of 13.
Therefore, we can say that the digital work program did not have a statistically significant effect on the amount of papers brought home by the students at Little Kids Elementary School.

It can be concluded that there exists ‘insufficient evidence’ depicting that the ‘new mean GPA is more than 2.75’.
Therefore, X= 2.7532; T = 0.1203; P = 0.4524.
How to solveH0: ‘The mean class GPAs for a given course’ is equal to 2.75.
H1: ‘The mean class GPAs for a given course’ exceeds 2.75.
Our 'sample size' n = 50 and we calculate the ‘sample mean and sd’ with 'Excel', through its respective code ‘AVERAGE()’.
The resultant ‘sample mean’ xbar equals to 2.7532, while implementing the code ‘STDEV.S()’ gives us the ‘sample sd’ s being 0.188164.
The ‘hypothesized mean’ μ0 is again fixed at 2.75. Given that the ‘population sd is unknown’, we are obliged to perform a ‘t-test’ in order to receive our data.
Evaluating this test statistic provides us with-
T = (xbar-μ0)/(s/√n)
= (2.7532-2.75)/(0.188164/√50)
= 0.0032/0.0266
= 0.1203
Also, taking into account the 'degrees of freedom', which is (n-1), we figure out that it sums up to 49.
After conjuring a 'students t distribution', we get a P-value of 0.4524. Hereby, as the ‘P-value surpasses the significant level of 0.05’, the ‘null hypothesis fails to be dismissed’.
Consequently, it can be concluded that there exists ‘insufficient evidence’ depicting that the ‘new mean GPA is more than 2.75’.
Therefore, X= 2.7532; T = 0.1203; P = 0.4524.

How to solve for the distanceJust add the values that tells us all the distamnce that he jogged
Write the values as improper fraction
(25/6) + (29/5)
To add these fractions, we need to find a common denominator, which is the least common multiple (LCM) of 6 and 5. The LCM of 6 and 5 is 30. Now we can convert each fraction to an equivalent fraction with a denominator of 30:
(25/6) * (5/5) = 125/30
(29/5) * (6/6) = 174/30
Now, add the fractions:
(125/30) + (174/30) = (125 + 174) / 30 = 299/30

What is Poisson probability?The Poisson probability distribution is a statistical distribution that models the probability of a certain number of events occurring in a fixed interval of time or space, given the average rate of occurrence of the events.
The Poisson distribution has a mean and variance of λ. Therefore, in this case, the mean and variance of the number of Internet traffic arrivals in one thousandth of a minute are equal to λ.
We can find the value of μ by dividing the total number of arrivals (7000) by the total time period (16,780):

We can use μ as the value of λ in the Poisson distribution since they are equal.
To find the probability of exactly 3 arrivals in one thousandth of a minute, we use the Poisson probability formula:
P(x=3) = (e^(-λ) * λ^x) / x!
where x = 3.
Substituting the values we have:

Michael has an average daily balance on his credit card of $327.50. His credit card charges 11.99% annual interest. What will his monthly finance charge be?
Answer:
First, we need to calculate Michael's daily interest rate:
0.1199 / 365 = 0.0003282
Then, we can calculate his daily finance charge:
327.50 x 0.0003282 = 0.1075

For the pyramid below draw the net and then calculate its total surface area using your net. ( picture is uploaded)
The total surface area of the pyramid from the net is 286 square cm
Calculating the total surface area from the netTo calculate the total surface area of a pyramid from its net, you need to add up the areas of all its faces.
The net of a pyramid is a two-dimensional representation of the pyramid, where the edges of the net represent the edges of the pyramid.
In this case, the nets are
Rectangle of: 10 by 7Pair of triangles of: 10 by 12.5, 7 by 13Using the above as a guide, we have the following:
Area = 10 * 7 + 2 * (1/2 * 10 * 12.5 + 1/2 * 7 * 13)
Evaluate
Area = 286
Hence, the surface area is 286 square cm

Show that " if x and y are odd integers, then x+y is even" using an indirect proof ( a proof by contraposition)
Using a proof by contraposition we can see that the sum must be even.
How to use the proof by contraposition?Here we know that x and y are odd integers, then we can write thes two numbers as:
x = 2n + 1
y = 2m + 1
Where n and m are integers.
If we use the proof by contraposition, then we will assume that the outcome is also an odd number 2k + 1
Then we can write:
2n + 1 + 2m + 1 = 2k + 1
We can simplify this to get:
2n + 2m + 1= 2k
2(n + m) + 1 = 2k
So there we have an odd number is equal to an even number, that does not make sense, thus, the outcome of the sum can't be odd.

The highest temperature on Day 7 is equal to 60 degrees.
The day in which the highest temperature was 60 degrees is day 3.
Yes, the high temperature is a function of the day because it is dependent variable.
No, the day is not a function of the high temperature because it is an independent variable.
What is an independent variable?In Mathematics, an independent variable can be defined as the variable that is being manipulated by an experimenter, scientist, or a researcher.
This ultimately implies that, an independent variable is always considered as the cause in an experiment and it is represented by the x-axis value on a graph.
In this context, we can reasonably infer and logically deduce that time measured in days represent the independent variable while the highest temperature measured in degree Fahrenheit represent the dependent variable.

Write an equation to represent the function: reflected over the x-axis, then translated 6 units left
The equation of the transformed function is y = -f(x + 6)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x
On simplifying , we get
Reflecting over the x-axis: To reflect a function over the x-axis, we multiply the function by -1. This changes the sign of the y-coordinate of each point on the graph of the function. So, the function after reflection over the x-axis would be y = -f(x).
Translating 6 units left: To translate a function 6 units to the left, we replace x with (x + 6). This shifts the graph of the function horizontally to the left by 6 units. So, the function after translation 6 units left would be y = -f(x + 6)
Hence , the function is y = -f(x + 6)

1. An acrobat is on a platform that is 25 feet in the air. She jumps down
at an initial vertical velocity of 4 ft/s. Write a quadratic function to
represent the height h of the acrobat t seconds after the jump.
If a safety net is placed 5 feet above the ground, how long will it take
for her to land safely on the net?
It will take the acrobat 1/4 of a second to land safely on the net.
What is velocity?Velocity is a physical quantity that measures the rate at which an object moves in a particular direction. It is measured in terms of distance traveled per unit of time, usually expressed in terms of meters per second (m/s). Velocity is a vector quantity, meaning it has both a magnitude and a direction. It is an important concept in physics and is used to understand the motion of objects and forces.
The quadratic equation representing the height h of the acrobat t seconds after the jump can be written as follows: [tex]h=-16t^2+4t+25[/tex].
To find the time it takes for the acrobat to land safely on the net, we need to solve for t when h=5. We can do this by substituting 5 for h into the equation and solving for t:
[tex]h=-16t^2+4t+25\\\\5=-16t^2+4t+25\\\\=-16t^2+4t-20=0\\\\(4+\sqrt{64})/(-32)=t\\ \\t=(4+8)/(-32)\\\\t=1/4[/tex]
Therefore, it will take the acrobat 1/4 of a second to land safely on the net.
