Answer:
A = 65, B = 75
Step-by-step explanation:
x + x + 10 + 40 = 180
2x + 50 = 180
2x= 130
x = 65
To solve this problem you must apply the proccedure shown below:
1. Clear the radius from the formula for the circumference of a circle and substitute values, as following:
![C=2\pi r\\ r=C/2\pi \\ r=37.699in/2\pi \\ r=5.99in](https://tex.z-dn.net/?f=%20C%3D2%5Cpi%20r%5C%5C%20r%3DC%2F2%5Cpi%20%5C%5C%20r%3D37.699in%2F2%5Cpi%20%5C%5C%20r%3D5.99in%20)
2. Substitute the radius calculated into the formula for calculate the surface area of the sphere:
![SA=4\pi r^{2} \\ SA=4\pi(5.99in^{2})\\ SA=450.88in^{2}](https://tex.z-dn.net/?f=%20SA%3D4%5Cpi%20r%5E%7B2%7D%20%5C%5C%20SA%3D4%5Cpi%285.99in%5E%7B2%7D%29%5C%5C%20SA%3D450.88in%5E%7B2%7D%20%20)
The answer is: ![450.88in^{2}](https://tex.z-dn.net/?f=%20450.88in%5E%7B2%7D%20%20)
Answer:
The probability of a customer buying carrots is 0.10.
Step-by-step explanation:
Here, given:
P (Customer buying apples) = 12%
⇒ P(A) = 12 \100 = 0.12
P(Customer Buying apples AND Carrots) = 5%
⇒ P(A ∩ C ) = 5 /100 = 0.05
P(Customer buying apples OR carrots ) = 17%
⇒ P(A∪ C) = 17/100 = 0.17
Now, we know that:
<h3>
P(X ∪ Y) = P(X) + P(Y) - P(X ∩ Y ) </h3><h3>
</h3>
Now, here substituting the values, we get:
P(A∪ C) = P(A) + P(C) - P(A ∩ C )
⇒ 0. 17 = 0.12 + P(C) - 0.05
or, 0.17 - 0.07 = P(C)
or, P(C) = 0.10
or, P(Customer Buying Carrots) = 0.10
Hence, the probability of a customer buying carrots is 0.10.
False. Anything times 0.8 except 0, is 0.8 or more.
