A screening test for a disease shows a positive result in 91% of all cases when the disease is actually present and in 7% of all
Jobisdone [24]

Answer:

0.0713 = 7.13% probability that the result is positive.

Step-by-step explanation:

Probability of a positive test:

91% of 1/650(has the disease).

7% of 1 - 1/650 = 649/650(does not have the disease). So

p = 0.91\frac{1}{650} + 0.07\frac{649}{650} = \frac{0.91 + 0.07*649}{650} = 0.0713

0.0713 = 7.13% probability that the result is positive.

A) if x=4 evaluate the perimeter of the blanket. Don’t forget to include the measurement in your final answer.
Tanzania [10]
Formula for perimeter of a rectangle:  P = 2W + 2L

Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14   (cm)

Combine like terms:  8x + 8   cm (simplest form)  This is the perimeter.

Now let x = 4:  P(x=4) = 8(4) + 8   cm   = 40 cm
