Answer: 12

Step-by-step explanation:

Given

The probability of getting yellow color is 0.24

If the no of trials is 50

\text{No. of times yellow color shown(N) is}=p\times \text{no of trails}\\\Rightarrow N=0.24\times 50=12\ \text{times}

Yellow color appears 12 times

Joshua uses the Small Business Administration (SBA) Loan Program to obtain a loan to help expand his vending machine business. J
TiliK225 [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

Principal amount Joshua borrowed, P = $ 25000

rate of interest, r = 1.5 %

time, t = 2 years

simple interest = \frac{P*r*t}{100}

simple interest = \frac{25000*1.5*2}{100}=750

Means $ 750 will be the interest of Joshua's loan.

So, Joshua needs to repay the SBA = 25000+750=25750

Hence, Joshua will repay $ 25750 to SBA after two years.   :   Answer

Hope it will help :)

Heeeeeeelp pleasee pleasee

I'm going to convert all the values given to you in percentages, so hopefully you should be able to see the correct answer a little clearer. :)

Debbie said that 21/50 drink coffee in the morning. 21/50 can also be written as 42/100, and now that it's out of 100, it's basically a percentage. (42%).

Allen said that 45% of people drink coffee in the morning. His value is already written as a percentage, so we won't do anything with it.

Benny says that 0.495 of the people he surveyed drink coffee in the morning. 0.495 is the same as 49.5% (multiply it by 100 to get it in a percentage).

So, in Debbie's survey, 42% of people drink coffee.
In Allen's survey, 45% of people drink coffee.
In Benny's survey, 49.5% of people drink coffee.

Therefore, the answer is Benny's survey. :)

If the life in years of a television set is normally distributed with a mean of 36 years and a standard deviation of 8 years wha
TiliK225 [7]

Answer:

The company should guarantee a lifetime of less than equal to 20.95 years so that less than 3% of the television sets fail while under warranty.    

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 36 years

Standard Deviation, σ = 8 years

We are given that the distribution of life of television sets is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.03.

P( X < x) = P( z < \displaystyle\frac{x - 36}{8})=0.03  

Calculation the value from standard normal z table, we have,  

\displaystyle\frac{x - 36}{8} =-1.881\\\\x = 20.952\approx 20.95  

Thus, the company should guarantee a lifetime of less than or equal to 20.95 years so that less than 3% of the television sets fail while under warranty.
