25m + 100 - 24m - 75 = 68.

Maksim231197 [3]

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

Rashid [163]

A random variable x is normally distributed with a mean of 100 and a variance of 25. Given that x = 110, its corresponding z- score is 0.40.

Answer: The given z-score is false.

Explanation: We are given:

Mean, $\mu=100$ ,

Variance, $\sigma^{2}=25$

$\therefore\sigma=\sqrt{\sigma^{2}}$

$=\sqrt{25}$

$=5$

The z-score formula is given below:

$z=\frac{x-\mu}{\sigma}$

$=\frac{110-100}{5}$

$=\frac{10}{5}$

$=2$

Therefore, the z-score corresponding x=100 is 2

Therefore, the given z-score = 0.4 is false.
