Seventy percent of kids who visit a doctor have a fever, and 30% of kids with a fever have sore throats. What’s the probability that a kid who goes to the doctor has a fever and a sore throat?

Answers

Answer:

0.21

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat

0.7 x 0.3 = 0.21

Find the value of X please help

Answers

Answer:

x = 119°

Step-by-step explanation:

The angle between chord KJ and chord LM is half the sum of the arcs intercepted by the angle and its vertical angle, that is

[tex]\frac{1}{2}[/tex] (75 + 47)° = 0.5 × 122° = 61°

This angle and x are adjacent angles and sum to 180° , then

x = 180° - 61° = 119°

The spinner above is used in a game. What is the theoretical probability of the given event with one spin? P (5)

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually. How much will the investment be worth after 5 years? Round to the nearest dollar.

Answers

The value of his investment at the third year is
F (3)=300×(1.02)^(3)=318.36

The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22

The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year

The investment worth after 5 years to the nearest dollar will be $3601.

What is compound interest?

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Shawn has a bank account with $3,069. He decides to invest the money at 3.25% interest, compounded annually.

The worth of investment after 5 years is calculated as,

A = $3,069 x (1 + 0.0325)⁵

A = $3,069 x 1.0325⁵

A = $3,069 x 1.1734

A = $3601

The investment worth after 5 years to the nearest dollar will be $3601.

Answers

Answer:

150

Step-by-step explanation:

Surface area is the area of all the surfaces (or sides). To find the surface area, find the area of one side of the cube. Since a side of a cube is a square, all the lengths are the same. So, 5*5= 25. There are 6 sides to a cube, so multiply 6 by one of the faces 's area (aka sides), so 6*25=150.
