Answer: 0.254
Step-by-step explanation:
Given that:
Number of cars = number of trials (n) = 8
Number that will be stopped by a red light = Numbe rof successes (r) = 3
Probability of success :
Red light = 15 seconds ; yellow = 5 seconds ; green = 30 seconds
P(red) = p(success) = p = 15 / (15 + 5 + 30) = 15/50 = 3 /10 = 0.3
1 - p = 1 - 3/10 = 7/10 = 0.7
Using the binomial probability relation:
p(exactly 3):
P(8, 3) = 8C3 * p^3 * (1-p)^(8-3)
P(8, 3) = 8C3 * p^3 * (1-p)^5
P(8, 3) = 56 * 0.3^3 * 0.7^5
= 0.25412
= 0.254

Each chair in the Cut and Style Shop can hold a maximum weight of 450 pounds. A large gentleman walked into the shop. He told his stylist that he weighed 75 pounds less than a quarter of a ton. By how many pounds is the gentleman over or under the maximum weight?
Answer: under by 25
Step-by-step explanation:
Because first you have to know how much a ton it's than find 1/4 of it. When you find in you subtract 75. After that you subtract your answer from 450

P(n,r)= n!
(n−r)! = ?
n (objects) = 5
r (sample) = 3
Answer:
P(n,r)=P(5,3)
= 5! /(5−3)!
= 60
The result shows that Mark can put the 5 pebbles in the 3 fish tanks in 60 different ways, if each fish tank must have at least one pebble. Using the permutation calculator, the number of ways is calculated to be 60 ways.

Anna is ordering t-shirts for a community run. The company Anna is ordering from charges $12 per shirt and a shipping fee of $8. Based on this information, which function can be used to represent the relationship between the total cost, t, and the number of shirts Anna orders, m?
A. t=12m−8
B. t = 8m + 12
C. t = 12m + 8
D. t=8m−12
Answer:
D. t = 12m + 8
Step-by-step explanation:
This is the correct answer. I took the test.
The linear function that models the situation is:
[tex]t = 12m + 8[/tex]
A linear function is modeled by:
[tex]t(m) = am + b[/tex]
In which:
a is the slope, which is the rate of change per unit m.b is the y-intercept, which is the "fixed" value.In this problem:
Charge of $12 per shirt, hence [tex]a = 12[/tex].Shipping fee of $8, hence [tex]b = 8[/tex]Thus, the relationship is modeled by:
[tex]t = 12m + 8[/tex]

Answer:
John’s calculations are not correct. He compared the exact value to the absolute error. The absolute error should be in the numerator and the exact value in the denominator.
Step-by-step Explanation:
Yes, he applied formula incorrectly.
Given : Expected value = $100
Actual value = $10
Then,
So, Yes, the calculation did by him was incorrect .

Using the information below, answer the next 3 questions: The percent of fat calories that a person in America consumes each day is normally distributed with a mean of about 36 and a standard deviation of about 10. Suppose that 16 individuals are randomly chosen. For the group of 16, find the probability that the average percent of fat calories consumed is more than thirty-five (Round to 3 decimal places)
Answer: 0.655
Step-by-step explanation:
Let X be a random variable that represents percent of fat calories that a person in America consumes each day.
As per given , X is normally distributed with a mean [tex]\mu=36[/tex] and a standard deviation [tex]\sigma=10[/tex].
Sample size : n= 16
The probability that the average percent of fat calories consumed is more than 35:
[tex]P(\overline{X}>35)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{35-36}{\dfrac{10}{\sqrt{16}}})\\\\=P(Z>\dfrac{-1}{\dfrac{10}{4}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>\dfrac{-4}{10})\\\\=P(Z>-0.4)\\\\=P(Z<0.4)\ \ \ [P(Z>-z)=P(Z<z)]\\\\=0.655\ \ \ [\text{By p-value table}][/tex]
Hence, Required probability =0.655
