Suppose the test scores of students in a class are normally distributed with a mean of 92 and a standard deviation of 3.

1 answer:

7 0

Hello!

The mean is 92 with a deviation of 3

You count down by 3 till you reach 86

92 - 3 = 89

89 is -1 deviation

89 - 3 = 86

86 is -2 deviation

The answer is -2

Hope this helps!

Katherine and Shally had $288 altogether. Katherine gave 1/3 of her share to Shally and their father gave $68 to Shally. They no

erastova [34]

1/3 of $288 is $96 So, therefore Shally had $96 at first.
But They both didn't have the same amount of money after too because:
1/3 of $288 is $96
$96 + $68 = $164 So Shally has $164

Now, $288 - $96 = $192. So Katherine has $192

So therefore they did not have the same amount of money but 1/3 of $288 is $96
