Answer:
=452.16 ft^3
Step-by-step explanation:
Volume of cylinder formula: V=πr^2(h)
Note: Diamater/2=radius
Plug-in: V=3.14(4)^2(9)
=452.16 ft^3
The second option: “Keep track of the number of heads flipped in 50 flips. These represent the number of females born today.”
One flip represents one baby born, and one head represents a female birth, so the total number of heads out of 50 flips simulates finding the ratio of females in a sample of 50 births.
Y=-x+b
plug in x = 4 and y = 1 to find b
1 = -4 + b and we know that if you add 5 and -4 you get 1. So ...
5 = b so if we plug that in
y= -x + 5
which is the same as y + x = 5, So it would be A
Answer: 9
Step-by-step explanation:
From doing the math I think it should be 9
Answer:
A
Step-by-step explanation:
We know that in normal distribution, approximately 34% of bags will fall with in one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
So the answer is 1
That means, that 68% is the answer.
