Answer:
Hi there!
The correct answer to this question is: 0.00770734662926
Step-by-step explanation:
because it's (5+3/12)^12
Mean is same as average
to find average
add up terms
divided that sum by the number of terms you have
example
mean of x,y,z
x+y+z
3 terms
(x+y+z)/3=mean
so
represent next test score as x
89+94+82+84+98+x
count how many terms ther are (6 terms)
mean is 90
(89+94+82+84+98+x)/6=90
add the like terms
(447+x)/6=90
multiply both sides by 6 to clear fraction
447+x=540
subtract 447 from both sides
x=93
she needs a score of 93 on next test
