Answer: 97.72%
Step-by-step explanation:
Given : A shoe manufacturer collected data regarding men's shoe sizes and found that the distribution of sizes exactly fits the normal curve.
Let x be the random variable that represents the shoe sizees.
Also, The population mean = 
; Standard deviation: 
Formula for z:-
Put x= 8, we get
Now, the probability that the male shoe sizes are greater than 8 :-
Hence, the percent of male shoe sizes are greater than 8 is 97.72%.
The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a length of an arc of a circle of radius 7 is approximately 10.99 cm.
The radius r = 7 cm
The arc length l = 10.99 cm
We know,
l = rθ
θ is the central angle.
θ = l/r = 10.99/7 = 1.57 radians
To convert 1.57 radians into the degree multiply it by 180/π
θ = 89.95 degree
Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.

Answer:
17 boxes
Step-by-step explanation:
Let x be the number of boxes that you can buy.
14x = 150
x = 250 / 14 = 17.85
We cannot buy 0.85 of a box, so we can only buy 17 boxes.
