What are the odds in favor of choosing a person at random who chose juice a?

stealth61 [152]

37:53

Step-by-step explanation:

Step 1 :

Given

Number of people choosing Juice A = 37

Number of people choosing Juice B = 32

Number of people choosing Juice C = 21

We need to find the odds in favor of choosing a person who chooses juice A

Step 2 :

Here the number of success is the number of people choosing juice A = 37

Number of failures is the number of the people not choosing juice A = Number of people choosing juice B + Number of people choosing juice C = 32+21 = 53

Hence the odds in favor of choosing a person who chooses juice A is 37:53

An office manager needs to decide between two tables for the conference room. One is rectangular, 5 feet wide by 10 feet long. T

7nadin3 [17]

Answer:

The rectangular 5 x 10 table.

Step-by-step explanation:

To find which table the office manager needs to get so he can sit more people at it is decided by one factor, the perimeter. The rectangular one, which is 5 x 10 the perimeter is (5 x 2) + (10 x 2) = 10 + 20 = 30. The circular one can be calculated by the equation $\pi * d$ where d = 8. Putting $/pi$ x 8 in my calculator and it comes out approximately at 25.132, having a less amount of perimeter space to work with, making the rectangular table the way to go.

A factory produces car tires. The number of miles each tire lasts before it completely wares out follows a normal distribution w

qwelly [4]

Answer: 0.0668073

Step-by-step explanation:

Given : The number of miles each tire lasts before it completely wares out follows a normal distribution with mean μ = 50,000 miles and standard deviation σ = 8,000 miles.

Let x be the random variable that represents the number of miles each tire lasts.

z-score : $\dfrac{x-\mu}{\sigma}$

For x= 62,000

$z=\dfrac{62000-50000}{8000}=1.5$

By using the standard z-value table , the probability for a randomly selected tire to last for at least 62,000 miles will be :_

$P(x\geq62000)=P(z\geq1.5)=1-P(z$

Hence, the probability for a randomly selected tire to last for at least 62,000 miles = 0.0668073
