3/5 i believe. if you take 7 and divide it by 2 its 3.5.
Answer:
see explanation
Step-by-step explanation:
Using the rule of exponents
= 
, then
2 ÷ 
= 2 ÷ 
To divide leave first, change ÷ to × , turn second upside down
= 2 × 
Answer:
26.2 feet
Step-by-step explanation:
tan(50°) = h/22
h = 22 × tan(50°) = 26.2 feet
Answer:
90
Step-by-step explanation:
The sum of squares of the deviation from mean=sum(x-xbar)²=?
x
12
6
15
9
18
12
xbar=sumx/n
xbar=(12+6+15+9+18+12)/6=72/6=12
x x-xbar (x-xbar)²
12 12-12=0 0
6 6-12=-6 36
15 15-12=3 9
9 9-12=-3 9
18 18-12=6 36
12 12-12=0 0
sum(x-xbar)²=0+36+9+9+36+0=90
So, the sum of squares of the deviations from the mean is 90.
There is nothing there sorry
