The value of n such that the number n and -3/4 are additive inverses is 3/4

<h3>How to determine the value of n?</h3>

The statement is given as:

The number n and -3/4 are additive inverses

The above statement means that

n = -1 * -3/4 --- by the definition of additive inverses

Next, we evaluate the product of -1 and -3/4

n = 3/4

Hence, the value of n such that the number n and -3/4 are additive inverses is 3/4

For a sample of n = 30 scores, X = 45 corresponds to z = 1.50 and X = 40 corresponds to z = +1.00. What are the values for the s
TEA [102]

Answer:

30

Step-by-step explanation:

Here, it is given that the Z – score corresponding to the score X = 45 is 1.5 and the Z – score corresponding to the score X = 40 is...

Z = \frac{X - M}{S}

So:

1/ 1.5 = \frac{45 - M}{S} and 1 = \frac{40 -M}{S} . solve the both equations, we found out:

<=> S = 10

=> M = 30

Hence, mean is:

M = 45 -1.5S = 45 - 1.5 (10) = 30
