Answer:
27 cubic units
Step-by-step explanation:
Volume = length • width • height
3 • 3 • 3 = 27 (Break it down by solving 3 • 3 = 9. Then 9 • 3 = 27)
Answer:
7%
Step-by-step explanation:
14+Sale tax=14.98
14.98-14=sale tax
14.98-14=0.98
0.98 is the sale tax now we need to find the percent
Let represent t percent
14 of t%=0.98
14*t/100=0.98
we need to use inverse operation to isolate T on one side so if its multiplication we need to do division on both sides to un-due multiplication.
So to move 100 we need to multiply on both sides and we will get
14*t=0.98*100
0.98*100=98
14*t=98
to move 14 we need to divide
14/14=1
we dont need to put 1t becuase t is =1
so we just write it as t
98/14=7
t=7
so Sale tax percent is 7%
Answer:
Im confused on what the question is, ill change my answer when i can somehow understand the question
Step-by-step explanation:
Im confused what the question is
Let m be mean
Mean= sum/ n
Mean= (1720+1687+1367+1614+1460+1867+1436) / 7
m= 11151 / 7
M= 1593
Mean= 1593
Standard deviation
|x-m|^2
For 1st: |1720-1593|^2=8836
For 2nd: |1687-1593|^2=10201
For 3rd: |1367-1593|^2=51076
For 4th: |1614-1593|^2=441
For 5th: |1460-1593|^2=1689
For 6th: |1867-1593|^2=75076
For 7th: |1436-1593|^2=24649
Summation of |x-m|^2 = 171968
Standard deviation sample formula is:
S.D = sqrt((summation of |x-m|^2) / n-1)
S.D=sqrt(171968/6)
S.D=sqrt(28661.33)
S.D=169.30
Standard deviation is 169.30
