Answer:
115°
Step-by-step explanation:
Measure of the degree of the angle represented by section B on the chart = percentage in the pie chart ÷ 100 × 360. A full circle makes 360°.
Section B represents 32% of the pie chart, therefore, number of degrees for section B =
Section B = 115° (to the nearest whole number)
A is 3/10 , if we multiply top and bottom by 4 we get 12/40 , which is not equivalent to 12/20.
B is 5:3 , it cannot be equivalent to 12/20.
C is 120 to 200 , if we divide both numerator and denominator by 10 we get 12/20, So option C is correct.
D is 60/80 , if we divide both numerator and denominator by 5, we get 12/16 , which is not equivalent to 12/20.
Hence option C is the correct answer.
Answer:
Probability that it does not rain during the entire festival = 0.19584
Step-by-step explanation:
We are given that you and a group of friends are going to a five-day outdoor music festival during spring break.
Also, Probability that there may be rain on first day, P(A) = 0.15
Probability that there may be rain on second day, P(B) = 0.10
Probability that there may be rain on third day, P(C) = 0.20
Probability that there may be rain on fourth day, P(D) = 0.20
Probability that there may be rain on fifth day, P(E) = 0.60
It is also provided that these probabilities are independent of whether it rained on the previous day or not.
Now, probability that it does not rain during the entire festival = Probability that there may not be rain on all five days
= (1 - P(A)) (1 - P(B)) (1 - P(C)) (1 - P(D)) (1 - P(E))
= (1 - 0.15) (1 - 0.10) (1 - 0.20) (1 - 0.20) (1 - 0.60)
= 0.85 0.90 0.80 0.80 0.40 = 0.19584
O B. Y= 2x – 9
O C. y² = x - 2
O D. x² + y² = 9
the answer is B -- no matter the x factor y should be single
friends. Keychains cost $2 each, and refrigerator magnets cost $1
each. Let x represent the number of keychains that Rosa bought,
and let y represent the number of refrigerator magnets.
Rosa bought 12 items and paid $18 more for the keychains than
for the refrigerator magnets.
9514 1404 393
Answer:
Step-by-step explanation:
We assume you want to know how many of each item Rosa bought.
The problem information lets us write two equations:
x + y = 12
2x - y = 18
Adding the two equations, we get ...
3x = 30
x = 10 . . . . . divide by 3
y = 12 -x = 2 . . . find y
Rosa bought 10 keychains and 2 magnets.
