The probability that a randomly selected single parent in the U S military is In the Army is:_______
P = number of required outcome/ Total possible outcomes
P(single parent) :
Number of required outcomes = (number of single parents in the army = 38000
Total number of single parents in the military = 87000
P(single parent in army) = 38000 / 87000 = 38/87

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]

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

The distance between two towns is 120 kilometers there are approximately 8 kilometers in 5 miles which measurement is closest to the number of mules between these two towns
Answer:
75 Kilometers
Step-by-step explanation:
We have been given that the distance between two towns is 120 km.
We are also told that there are approximately 8 km in 5 miles. Let us find number of miles per km by dividing 5 by 8.
\text{Number of miles in 1 km}=\frac{5\text{ miles}}{\text{8 Km}}
\text{Number of miles in 1 km}=0.625\frac{\text{ miles}}{\text{ Km}}
Therefore, there are 0.625 miles in 1 km.
To convert our given distance into miles we will multiply our given distance by number of miles in 1 km.
\text{Number of miles in 120 km}=120\text{ km}\times \frac{0.625\text{ miles}}{\text{ km}}
\text{Number of miles in 120 km}=120\times 0.625\text{ miles}
\text{Number of miles in 120 km}=75\text{ miles}
Therefore, the distance between two towns is 75 miles.
Answer:
The answer is 75, I had this question a few days ago and I got it right
