The statement of the problem is
Kevin’s family has a history of diabetes. The probability that Kevin would inherit this disease is 0.75. Kevin decides to take a test to check if he has the disease. The accuracy of this test is 0.85
Probability
Test predicts he has it 0.85
Test predicts he doesn’t have it 0.15
Kevin has diabetes 0.75
<span>Kevin doesn’t have diabetes 0.25
</span>
Answers
<span>1) </span>The
probability that Kevin has diabetes and the test predicts he has diabetes
P=0.75*0.85=0.6375
<span>2) </span>The
probability that Kevin has diabetes and the test predicts the opposite to the
true
P=0.75*0.15=0.1125
<span>3) </span>The
probability that Kevin not have diabetes and the test predicts it correctly
P=0.25*0.85=0.2125
<span>4) </span>The
probability that Kevin not have diabetes and the test predicts he has diabetes
P=0.25*0.15=0.0375
Yes it is an imaginary number.
Answer:
B and C
Step-by-step explanation:
Using quadratic formula as it is shown in the attached picture
Answer:
$60
Step-by-step explanation:
To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.
Sales tax + Tips = $18.60
Let x = original price
Sales tax = 11% * original price
Sales tax = 0.11 * x
x= 0.11x
Tips = 20% * original price
Tips = 0.20 * x
x = 0.2x
Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:
0.11x + 0.2x = 18.60
0.31x = 18.60
Now we need to divide both sides by 0.31 to find x.
![\dfrac{0.31x}{0.31}=\dfrac{18.60}{0.31}](https://tex.z-dn.net/?f=%5Cdfrac%7B0.31x%7D%7B0.31%7D%3D%5Cdfrac%7B18.60%7D%7B0.31%7D)
x = 60
Zoe's dinner before the sales tax and tips was $60.
