Answer:
228 cm²
Step-by-step explanation:
The volume of a cylinder of radius r and height h is given by ...
V = πr²·h
Filling in the given information, we can solve for r:
235.5 = π·r²·12
√(235.5/(12π)) = r ≈ 2.49937 . . . . cm
The area of a cylinder is given by ...
A = 2πr² + 2πrh = 2πr(r +h)
Filling in the radius and height, we can find the area to be ...
A = 2π·2.49937·(2.49937 +12) ≈ 227.698 . . . . cm²
About 228 cm² of aluminum are required to make a typical soda can.
Answer:
D&B
Step-by-step explanation:
turn 6 to a fraction which is 6/1
So you keep the first fraction the same
change the division sign to a multiplication sign
change 3/4 to 4/3
so 6/1x4/3
multiply straight across the top and bottom
you get 24/3
simplified is 1/8lbs
Answer:
y=-7/2x - 2
Step-by-step explanation:
The slope is heading downwards so we know it is negative, for every two units moved on the x axis the y axis moves by 7 units. The starting point is -2
26.8% of examinees will score between 600 and 700.
This question is based on z score concept.
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.

where:
μ is the mean
σ is the standard deviation of the population
Given:
μ = 560
σ = 90
For
600≤ X≤700
for x = 700
Z score =x - μ/σ
=(700 - 560)/90
= 1.55556
P-value from Z-Table:
P(560<x<700) = P(x<700) - 0.5 = 0.44009
for x = 600
Z score =x - μ/σ
=(600 - 560)/90
= 0.44444
P-value from Z-Table:
P(560<x<600) = P(x<600) - 0.5 = 0.17164
∴ P(600<x<700) = P(560<x<700) - P(560<x<600)
= 0.44009 - 0.17164
=0.26845
∴26.8% percentage of examinees will score between 600 and 700.

Answer:
Domain = {-6, -2, -1, 3, 5}
Step-by-step explanation:
The domain represents the input or x values of a given relation.
In the given set of ordered pairs: (-2, 4) (-6,8) (3,6) (5,15) (-1, 4)
Domain (input/x values) = {-6, -2, -1, 3, 5}
Range (output/y values) = {4, 6, 8, 14}
