Answer:
Let the number be x
The expression above is written as
15x² = 20x
Divide both sides by x
We get
15x²/x = 20x/x
15x = 20
Divide both sides by 15
x = 20/15
x = 4/3
Hope this helps

Answer:
The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.
Step-by-step explanation:
The point estimate of the mean of the sample is (<span>39 + 31 + 38 + 40 + 29 + 32 + 33 + 39 + 35 + 32 + 32 + 27 + 30 + 31 + 27 + 30 + 29 + 34 + 36 + 25 + 30 + 32 + 38 + 35 + 40 + 29 + 32 + 31 + 26 + 26 + 32 + 26 + 30 + 40 + 32 + 39 + 37 + 25 + 29 + 34) / 40 = </span>1292/40 = 32.30
The point proportion of defective units is 2/40 = 0.05
