Seventy percent of children who go to the doctor have fevers. Of those with fevers, 30% also have a rash. Of those without fever
Allisa [31]

Answer:

The probability that a child with a rash does not have a fever is 22%

Step-by-step explanation:

1. Probability of having fever:

P(fever)=0.70

2. Probability of not having fever:

P(not fever)=1-P(fever)\\P(not fever)=1-0.70\\P(not fever)=0.30

3. Probability of fave fevers and a rash:

P(fever and rash)=(0.70)(0.30)=0.21

4. Probability of having a rash but not a fever:

P(rash and not fever)=(0.30)(0.20)=0.60

5. Probability of having a rash:

P(rash)=P(rash and fever)+P(rash and no fever)\\P(rash)=0.21+0.06=0.27

6. Probability a child with a rash does not have a fever

P=\frac{P(rash and not fever)}{P(rash)} =\frac{0.06}{0.27} =0.22

22% of the child at the doctor's office with a rash does not have a fever.

Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l=7 cm. Find the sum of all edges
Lelu [443]
The correct answer is 50 cm or 500 mm. There are 4 base edges and 4 lateral edges, so just multiply the number for both edges by 4 and add. The question threw a curveball at us by giving us two units of measurement, millimeters and centimeters, but since we know that there are 10 millimeters in a centimeter, we can just divide 55 by 10 to get 5.5.

5.5 x 4 = 22
7 x 4 = 28
28 + 22 = 50

If it helps, you can draw the figure and label the edges. Remember that the lateral edge of a quadrilateral pyramid is the slanted line leading up to the top of the pyramid, and that the base edges are the sides of the quadrilateral on the bottom.

Hope this helps!
