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
Devaughn is 6 years older than Sydney. The sum of their ages is 70. What is Sydney's age?
Answer:
29
Step-by-step explanation:
if you take 70 and divide it by 2 (cuz there are 2 People) then subtract 6 (because ones 6 years older) then you get 29

Permutations nPr Calculator
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.
At the Town Savings Bank, a new customer earns $2,950 in simple interest on a $5,000 deposit over the first 10 years. What rate of interest does that bank pay?
9514 1404 393
Answer:
5.9%
Step-by-step explanation:
The interest rate formula is useful:
I = Prt . . . . interest on amount P at rate r for t years
2950 = 5000·r·10
r = 2950/50000 = 0.059 = 5.9%
The bank pays 5.9% interest.

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]
