Answer:
864 miles
Step-by-step explanation:
648/9 = 72 mph
72 x 12 = 864
Answer:
The mean point is 459
Step-by-step explanation:
We use the formula:
Evelyn's points per pinball game are normally distributed with a standard deviation of 18 points.
This means:
From the question, the standard deviation of 405 points is -3.
We substitute x=405, and z=-3 to get:
Multiply through by 18 to get:
Divide through by -1
Answer:
<u>Step-by-step explanation:</u>
The standard form for an ellipse is: where
- (h, k) is the center
- a is the radius on the x-axis
- b is the radius on the y-axis
Given: (h, k) = (0, 0)
a = 8 (distance on x-axis from origin to -8)
b = 4 (distance on y-axis from origin to 4)
Input h = 0, k = 0, a = 8, b = 4 into the standard form for an ellipse:
Basically, you just have to distribute and then add. Let's do that:
30.
Combine like terms (and this is your answer):
31. Same thing (except convert 1 and 1/5 to an improper fraction):
Hope this helped!
<span>the answer:
the main condition can be found one of the following given methods:
if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B
in our case we have C = 2*Pi* R, if we want to find the value of Pi, it is Pi = C / 2*R
the true answer is D</span>
