Convert to degrees
34°18' is the same as 34° 18' 0"
34° 18' 0" = 34° + 18'/60 + 0"/3600
= 34.3°
putting tan(34.3) into a calculator in degree mode
tan ( 34°18' )= tan(34.3) = 0.6822
The product of 3/5 x 7/4 is 1 1/20
1 is whole number and then the fraction is 1/20
1 1/20 in decimal form is 1.05
Answer:
402.1 in^2
Step-by-step explanation:
Find the area of the circle with the 18 in. radius first.
Formula for a circle is πr^2
So the area of the circle with the 8 in. radius is 1017.9 in^2
Now do the same for the 14 in. radius circle.
The area for the 14 in. radius circle is 615.8
Now subtract:
1017.9 - 615.8 =
402.1 in^2
hope this helped!
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
It’s is 15/31 because you have to add 15+16 and you get 31 so since there is 15 boys it would be 15/31
