Suppose that 2 were subtracted from each of the values in a data set that
originally had a standard deviation of 7.5. What would be the standard
deviation of the resulting data?
o
ن
O A. 2
OB. 9.5
C. 5.5
O D. 7.5

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
