P(Green ball) = 1/3
Step-by-step explanation:
You have a sack of 90 balls. 35 blue, 30 green and 25 pink. If you randomly pull one ball out of the bag, what is the probability of pulling a green ball?
The Probability of pulling a green ball =
P(Green ball) =
Number of green balls/ Total number of balls
= 30 green balls/90 balls
P(Green ball) = 1/3
Answer:
<h2>Mjhs needs 189.25 square feet of blue paint, approximately.</h2>
Step-by-step explanation:
As you can observe in the image attached, the basketball court is a composite figure formed by a rectangle and half of a circle.
The rectangle has dimensions of 10 feet by 15 feet. The circle has a diameter of 10 feet.
The expression of this composite area would be
![A= w \times l + \frac{\pi (\frac{l}{2} )^{2} }{2}](https://tex.z-dn.net/?f=A%3D%20w%20%5Ctimes%20l%20%2B%20%5Cfrac%7B%5Cpi%20%28%5Cfrac%7Bl%7D%7B2%7D%20%29%5E%7B2%7D%20%7D%7B2%7D)
Where
and
. Replacing these values, we have
![A= 15 \times 10 + \frac{3.14 (\frac{10}{2} )^{2} }{2}\\ A=150 + \frac{3.14 \times 25}{2}=150+39.25 \\ A \approx 189.25 \ ft^{2}](https://tex.z-dn.net/?f=A%3D%2015%20%5Ctimes%2010%20%2B%20%5Cfrac%7B3.14%20%28%5Cfrac%7B10%7D%7B2%7D%20%29%5E%7B2%7D%20%7D%7B2%7D%5C%5C%20A%3D150%20%2B%20%5Cfrac%7B3.14%20%5Ctimes%2025%7D%7B2%7D%3D150%2B39.25%20%5C%5C%20A%20%5Capprox%20189.25%20%5C%20ft%5E%7B2%7D)
Therefore, Mjhs needs 189.25 square feet of blue paint, approximately.
The number is positive, so she has money in her account. The answer is B.
