(7 points) Cars arrive at a toll both according to a Poisson process with mean 80 cars per hour. If the attendant makes a two-minute phone call, what is the probability that at least 1 car arrives during the call
Answer:
The probability that at least 1 car arrives during the call is 0.9306
Step-by-step explanation:
Cars arriving according to Poisson process - 80 Cars per hour
If the attendant makes a 2 minute phone call, then effective λ = 80/60 * 2 = 2.66666667 = 2.67 X ≅ Poisson (λ = 2.67)
Now, we find the probability: P(X≥1)
P(X≥1) = 1 - p(x < 1)
P(X≥1) = 1 - p(x=0)
P(X≥1) = 1 - [ (e^-λ) * λ^0] / 0!
P(X≥1) = 1 - e^-2.67
P(X≥1) = 1 - 0.06945
P(X≥1) = 0.93055
P(X≥1) = 0.9306
Thus, the probability that at least 1 car arrives during the call is 0.9306.

A line intersects the points (0,-4) and (1,2). What is the slope-intercept equation for this line
Answer:
y = -2x
Step-by-step explanation:
First you can find the difference between the two points to find the slope.
0, 4
- 1, 2
-1, 2
Now divide: y/x = 2/-1 = -2
Slope = -2
Formula: y=mx+b
Plug in the points for the variables.
2 = -2(1) + b
2 = -2 + b
Subtract 2 from both sides to get 0 = b so this line is proportional.
Hope that helps and have a great day!

Find the distance between Point A(9, 10) and B(-1,9) to the nearest tenth.
Answer:
10.0
Step-by-step explanation:
see attached for reference.
given two points in the x-y axis (x₁, y₁) and (x₂, y₂)
the distance bettween them is given by
Distance, D = √ ( (x₂-x₁)² + (y₂-y₁)² )
In our case we are given points (9,10) and (-1,9)
substituting these into the formula , we get:
D = √ ( (9-10)² + (-1-9)² )
= √ ( (-1)² + (-10)² )
= √ ( 1 + 100 )
=√101
= 10.04988
= 10.0 (rounded to nearest tenth)
Write 75% as a rate per 100
Answer:
75/100 = 3/4
Step-by-step explanation:
75% in rate form is: 75/100, which can be also given in reduced fraction form by simplifying two factors "5" : 75/100 = 3/4
Which transformation carries the trapezoid onto itself?
A. a reflection across the line y = 0
B. a rotation of 180° about the point (- 1, 0)
C. a rotation of 180 ° about the origin
D. a reflection across the line x = - 1 -1
Answer: D. a reflection across the line x = - 1
Step-by-step explanation:
First, you can see that the lengths of the top and the base of the figure are different, so we can discard the rotations of 180°, because those will give a different figure.
Now, for reflections, we need to reflect the image around a line of symmetry.
A line of symmetry means that the image at the right of the figure is an exact reflex of the image at the left of the figure, for this particular case, we can find a line x = c. Such that the distance between c and the x-component of the top vertexes is the same for both of them.
(Again, because the top and the bottom have different lengths, there is no line y = b such that a reflection across that line will leave the figure invariant)
The left top vertex is at x = -3
The right top vertex is at x = 1.
We can find the mid-value between them as:
c = (-3 - 1)/2 = -2/2 = -1
Then:
-3 - c = -3 - (-1) = -3 + 1 = -2
1 - c = 1 - (-1) = 2
While the numbers are different (in sign) as those represent distance between points, we only care for the absolute value, in that case:
I-2I = I2I
Then the distances are exactly the same, and we can take c = -1
This means that a reflection about the line x = -1 carries the figure onto itself.
Then the correct option is:
D. a reflection across the line x = - 1

Answer:
40 miles
Step-by-step explanation:
15 + 0.50m = 25 + 0.25m
0.50m = 10 + 0.25m
0.25m = 10
m = 40
The total charge in dollars for a car rental can be determined by using the function c = 0.4x + 35, where c represents the total cost of the rental and x represents the total distance traveled in miles. Which statement justifies that the total cost for renting this car and driving a distance of 100 miles is $75.00? The total cost increases $0.40 for every 35 miles traveled. The total cost increases $35.00 for every 40 miles traveled. There is an initial charge of $35.00 for every mile traveled. The cost increases $0.40 for every mile traveled after an initial charge of $35.00.
Answer:
There is an initial charge of $35.00 for every mile traveled.
Step-by-step explanation:
From the question, the cost function s given as follows:
c = 0.4x + 35 .................... (1)
Where;
Total cost = c
Variable cost per mile = $0.40
Number of miles traveled = x
Total variable cost = 0.4x = 0.40 * x
Fixed cost = Initial cost = $35
From the above, the fixed cost or initial cost implies that no matter the number of miles a passenger takes, he is going to pay $35 in addition to the variable cost to pay.
From the question, for driving a distance of 100 miles we have:
Number of miles traveled = x = 100
Total variable cost = 0.40 * 100 = 40
Substituting the relevant value into equation (1), we have:
c = 40 + 35
c = 75
Since the total cost obtained above is $75.00, it therefore implies that the correct statement that justifies that the total cost for renting this car and driving a distance of 100 miles is $75.00 is "There is an initial charge of $35.00 for every mile traveled".
if the area of the right angle to measure 308 square meters and solve an equation to find the value of y
Answer:
y = 14
Step-by-step explanation:
Area of rectangle = 308 m²
Length = (6y - 7) m
Width = 4 m
Area of rectangle = length × width
Plug in the values
308 = (6y - 7) × 4
308 = 6y×4 - 7×4
308 = 24y - 28
Add 28 to both sides
308 + 28 = 24y
336 = 24y
Divide both sides by 24
14 = y
y = 14
The length of a jogging trail is 3528 m. A jogger wants to complete the trail within 30 min. How many meters must the jogger travel each minute?
Step-by-step explanation:
We have to find the distance the jogger must travel each minute. The distance covered in one minute is:
d= 3528/1800= 1.96 m
Therefore, the distance covered in one minute, or 60 seconds is:
dt= 1.96 × 60 = 117.6 m
The solution needed is, dt=588/5 = 117 (3/5) m

The width of a piece of paper is 8.5in the length is 11in and the thickness is 0.0037inches there are 2700sheets sitting in a cabinet by the copy machine what is the volume of occupied by the paper.
Answer:
934.2 in³
Step-by-step explanation:
The following data were obtained from the question:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Number of paper = 2700 sheets
Volume occupied by the 2700 sheets of paper =?
Next, we shall determine the volume of 1 sheet of paper. This can be obtained as follow:
Width (W) = 8.5 in
Length (L) = 11 in
Thickness (T) = 0.0037 in
Volume (V) =?
Volume = Length × Width × Thickness
Volume = 11 × 8.5 × 0.0037
Volume = 0.346 in³
Thus, the volume of 1 sheet of paper is 0.346 in³
Finally, we shall determine the volume occupied by the 2700 sheets of paper as follow:
Volume of 1 sheet of paper = 0.346 in³
Volume of 2700 sheets of paper =?
1 sheet of paper occupied 0.346 in³.
Therefore, 2700 sheets of paper will occupy = 0.346 × 2700 = 934.2 in³
Thus, the volume occupied by the 2700 sheets of paper is 934.2 in³.

Sam and Carlos are bowling with plastic pins in Sam's living room.
Remarkably, Sam knocks down 8 pins on every bowl, and Carlos knocks down 9 pins on every bowl. At the end of the day, Sam and Carlos have knocked down the same total number of pins.
What is the least number of total pins that Sam and Carlos could have each knocked down?
What is the slope-intercept form of the equation of the line through the given point and slope?
through: (2,-2), slope = -3
Answer:
b = 4
Step-by-step explanation:
Remember y = mx+b (m = slope, b = y intercept.)
We have the slope, so, no need to solve for that.
To find the y intercept, plug in the ordered pairs to y=mx+b
-2=-3(2)+b
-2=-6+b multiply like terms
4 = b Add 6 on both sides
b = 4.
