Answer:
Step-by-step explanation:
Given that Heights of 10-year-olds, regardless of gender, closely follow a normal distribution with a mean of 55 inches and a standard deviation of 6 inches.
If X is height then X is N(55,6)
Z score would be 
b) 
c) Tallest 10% z = 1.28
X score = 
inches
d)
i.e. 16.37% cannot go on this ride.
Imagine this pole of height h sticking out of the ground. A wire of length 15 feet connects the top of the pole to a stake in the ground which is located 5 feet from the base of the pole. This arrangement creates a right triangle with legs h (the height of the pole), 5 ft (distance of bottom of pole from stake) and hypotenuse 15 ft.
We can find the height of the pole (h) using either trig or the Pythagorean Theorem. If we use the P. T., then h^2 + 5^2 = 15^2.
This results in h^2 + 5^2 = 15^2, or h^2 + 25 = 225, and so:
h^2 = 200. Thus, h = +√200 = +10√2.
The height of the pole is 10√2 ft, or approx. 14.14 ft.
Answer:
x=7
Step-by-step explanation:
Add 10 to both sides to isolate x.
4x=28
x=7
I think the answer is A. It has more potential energy because it is stretched out more & when you let go, it will have more kinetic energy.
The height scale is 75
Step-by-step explanation:
The height scale is the ratio between the height of the final image and the height of the original image.
In this problem, we have:
(height of the original image)
Converted into meters,
(height of the enlarged image)
Therefore, the height scale is given by the following ratio:
So, the height scale is 75.
