12.6 ft³
Step-by-step explanation:
h = 1 ft
r = 2 ft
π = 3.14
V of cylinder = πr²h
= 3.14 × 2² × 1
= 12.56
= 12.6 ft³
Hope it helps ⚜
Answer:
A) Mean = 135 Variance = 62 Standard Deviation = 8
Step-by-step explanation:
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8
You have to measure the lines with a ruler.
Answer: 14.50 - 6.95 = 7.55$
7.55 + 5.00 = 12.55$ spent on a snack?! dang she was hungry
Step-by-step explanation:
Answer:
(-1, 7, 2)
Step-by-step explanation:
we suppose that ax + by + cz = d for the matrix
D = det [ 0 4 7] = 100
-6 0 -2
1 2 8
Dx= det [ 14 4 7] = - 100
10 0 -2
-3 2 8
Dy= det [ 0 14 7] = 700
-6 10 -2
1 -3 8
Dz = det [ 0 4 14] = 200
-6 0 10
1 2 -3
So the solution is:
x = Dx/D = -1, y = Dy/D= 7, z =Dz/D = 2
(-1, 7, 2)
have a good day!
