We can convert the fraction to a denominator of 100, since percents are parts of 100.

39 * 2 = 78
50 * 2 = 100

So we have 78/100 or 78%

never [62]

I found the missing parts of this question.
Test A
Gregorio’s score 62 
Mean score 80 
Standard deviation 6 

Test B 
Gregorio's score 70 
Mean score 90 
Standard deviation 10 

a. Test A: 3; Test B: 2; Test A 
c. Test A: –2; Test B: –3; Test A 
b. Test A: –3; Test B: –2; Test B 
d. Test A: –3; Test B: –2; Test A


Refer to the attachment for the formula of z score:

test A: z = (62-80)/6 = -18/6 = -3
test B: z = (70-90)/10 = -20/10 = -2

B. Test A: –3; Test B: –2; Test B

Fill in the question mark ?5

timurjin [86]

Do you mean ?5x7 = 455 ?
because then it would be :
455 divided by 7 which equals 65 :)
