Answer:
120°
Step-by-step explanation:
Area of a sector is:
A = πr² (θ/360°)
Plugging in values and solving:
49/3 π = π (7)² (θ/360°)
49/3 π = 49π (θ/360°)
1/3 = θ/360°
θ = 120°
The correct option is If the bag is 7/8 full and 1/3 drops on the floor, the amount that drops on the floor is 7/8 x 1/3.
<h3>What is the correct option?</h3>
A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.
Multiplication is the mathematical operation that is use to determine the product of two or more numbers. The sign that is used to represent multiplication is x.
If the area of the park is 7/8 and the width is 1/3, the length is: area / width : 7/8 ÷ 1/3 = 7/8 x 3
If the bag is 7/8 full and 1/3 drops on the floor, the amount that drops on the floor is : 7/8 x 1/3.
If the rope is 7/8 long and he cuts off 1/3, the remaining rope is: 7/8 ÷ 2/3
The number of bowls that Julia can fill is: 7/8 ÷ 1/3 = 7/8 x 3

Answer: j = 13.5
Step-by-step explanation:
1) The probability that Kevin has diabetes and the test predicts opposite to be true = Probability Kevin has diabetes x Probability that test predicts opposite to be true.
Probability that Kevin has diabetes = 0.75
Probability that test predicts opposite to be true (i.e test predicts he doesn't have diabetes) = 0.15
So,
The probability that Kevin has diabetes and the test predicts opposite to be true = 0.75 x 0.15 = 0.1125
2) The probability that Kevin does not have diabetes and the test predicts this correctly = Probability Kevin does not diabetes x Probability that test predicts this correctly.
Probability that Kevin does not have diabetes = 0.25
Probability that test predicts this correctly (i.e. test predicts he does not have diabetes) = 0.85
So,
The probability that Kevin does not have diabetes and the test predicts this correctly = 0.25 x 0.85 = 0.2125
3) The probability that Kevin does not have diabetes and the test predicts the has diabetes = Probability Kevin does not diabetes x Probability that test predicts he has diabetes.
Probability that Kevin does not have diabetes = 0.25
Probability that test predicts has has diabetes = 0.15
So,
The probability that Kevin does not have diabetes and the test predicts the has diabetes = 0.25 x 0.15 = 0.0375
