Area = l x w
Area =9 x 4.25
A = 48.25
A≈ 48 in²
244 divided by 60 = 4.0666
Answer:
The answer would be option B.
Step-by-step explanation:
There are more people clustered in 22-25 years and the outlier is 38-41 years.
Answer:
14.2, 16.96
Step-by-step explanation:
given is a probability distribution of X
X is discrete taking values as 7, 11, 15 and 19
X 7 11 15 19 total
p 0.10 0.35 0.20 0.35 1
x*p 0.7 3.85 3.0 6.65 14.20
x^2*p 4.9 42.35 45 126.35 218 .60
Hence mean = sum of prob (x) = 14.20
9514 1404 393
Answer:
y = 2x -4
Step-by-step explanation:
The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:
-1/(-1/2) = 2
The point-slope form of the equation of a line can be used to find the desired equation:
y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m
For (x1, y1) = (2, 0) and m = 2, the equation is ...
y -0 = 2(x -20
y = 2x -4
