Zarrin [17]

Answer:

1.5

Step-by-step explanation:

The mean is the Middle number.

1 standard deviation in both sides of 7.5 makes it between 6 and 9.

What is the "common difference" in 6 to 7.5 and from 7.5 to 9?

$7.5-6=1.5$

and

$9-7.5=1.5$

So, we would say the standard deviation is 1.5

Answer choice A is right.

Vanyuwa [196]

Answer:

11/24

Step-by-step explanation:

7/8 + 11/12 + 3/4 + x = 3 km

7*3/8*3 = 21 / 24

11*2 / 12 * 2 = 22 /24

3*6 / 4*6 = 18/24

21/24 + 22/24 + 18/24 + x = 3

61 / 24 + x = 3

x = 72/24 - 61/24

x = 11 / 24

Tim has to run 11/24 of the race
