This number has to be read with its whole part first (twenty-three) and then its decimal part (one hundreth), so the complete sentence to read this number is twenty-three and one hundredth.
Answer: D. Twenty-three and one hundredth
<span>The number of cell phone minutes used by high school seniors follows a normal distribution with a mean of 500 and a standard deviation of 50. what is the probability that a student uses more than 580 minutes?
Given
μ=500
σ=50
X=580
P(x<X)=Z((580-500)/50)=Z(1.6)=0.9452
=>
P(x>X)=1-P(x<X)=1-0.9452=0.0548=5.48%

It would be B) 6 cm. If you construct the triangle, and add the angle measure of 80 + 50= 130 , and then 180- 130= 50, you see that the triangle is isosceles.

Answer:
3929 square feet
Step-by-step explanation:
The radius of the fence circle is half its diameter, so is 51.4 feet. The area of a circle is given by the formula ...
A = πr^2
The difference in areas of the two regions is found by subtracting the smaller area from the larger one. So, the difference in area between the fenced area of radius 51.4 feet and the playground area of radius 37.3 feet is ...
∆A = π(51.4^2 -37.3^2) = 1250.67π ≈ 3929 . . . square feet
Incorrect
if we solve x
we divide both side by 8 at 8x=56
therefore X=7
