Answer:
x = 20
Step-by-step explanation:
19 < x < 25
x had to be higher than 19 but lower than 25
18 cant be the answer because it is less than 19
27 cant be the answer because it is higher than 25
that leaves 20, which is the right answer
19 < 20 < 25
Answer:
75
Step-by-step explanation:
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.
Answer:
≈ 78mi^2
Step-by-step explanation:
To find approximate land area:
296,550/3,800 = 78.039
Round to nearest whole number:
Area = 78
