What is the answer to -4/3p -2/5

1 answer:

Answer:

Step-by-step explanation:

This expression consists of two fractions that have no common denominator but do have -2 as a common factor in the numerators.

Factoring out the -2, we get:

-2(2p/3 + 1/5)

If you want to go further, we can determine the LCD (which is 15) and then combine the fractions within parentheses:

-2(10p/15 + 3/15)

We could now factor out the 1/15 in each fraction:

-2

---- (10p + 3)

15

<span>a)

Z*_Upper = (76 - 62.7)/2.5 = 5.32

Z*_Lower = (57 - 62.7)/2.5 = -2.28

The requirement is to get p(-2.28 < Z < 5.32) = p(Z<5.32) - p(Z<-2.28).

Use normal distribution table to get the answer for p and multiply with 100 to get the percentage.

The other questions are now easy for you to answer on your own. Hope it helps.
