Shirts cost $20 each and ties cost $12 each.

<u>Expression for the cost:</u>

20s + 12t

Correct choice is B

<u>An expression that represents 40% of a number is:</u>

40*n/100 = 0.4n

Correct choice is B. False

t = -2, x = 3 and z = 5

4z + 3x − t =
4*5 + 3*3 - (-2) =
20 + 9 + 2 =
31

Correct choice is C. 31

A survey among freshman at a certain university revealed that the number of hours spent studying before final exams was normally

patriot [66]

Answer: 0.0775

Step-by-step explanation:

Given : Mean : $\mu = 25$

Standard deviation : $\sigma =15$

Sample size : $n=36$

Since its normal distribution , then the formula to calculate the z-score is given by :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x= 28.2 hours

$z=\dfrac{28.2-25}{\dfrac{15}{\sqrt{36}}}=1.28$

For x= 30 hours

$z=\dfrac{30-25}{\dfrac{15}{\sqrt{36}}}=2$

The P- value = $P(1.28$

$=P(z$

Hence, the probabiliy that the average time spent stydying for the sampe was between 28.2 and 30 hours = 0.0775
