Please answer this by solving it
mr Goodwill [35]

Answer:

5 5/6

Step-by-step explanation:

Change them into improper fractions.  Multiply the denominator by the whole number and then add the numerator.  Put that number over the denominator.

2 X 3 = 6           3 X 2 = 6

6 + 1 = 7            6 + 1 = 7

7/3                      7/2

New expression:    7/3 + 7/2

Find a common denominator.  Both denominators can go into 6.

14/6 + 21/6 = 35/6

Change this back into a mixed number by dividing.

Answer: 5 5/6

mafiozo [28]

The area to the right of z = 1.35 is 0.0885 and the area to the left of -0.47 is 0.3192.

<h3>How to compute the values?.</h3>

Given z = 1.35

= 1- P(z < 1.35)

= 1- 0.9115

= 0.0885

The area to the left of -0.47 will be:

= 1 - P(z < 0.47)

= 1 - 0.6808

= 0.3192
