Ber [7]

Answer:

The answer to your question is $40

Step-by-step explanation:

Data

Total payment = $240

Proportions Brian: Tim: Kenny 5:9:10

Process

1.- Sum the proportions

5 + 9 + 10 = 24

2.- Divide the total payment by the previous result

240 / 24 = 10

3.- Determine the money that every neighbor earn

Brian = 10 x 5 = 50

Tim = 9 x 10 = 90

Kenny = 10 x 10 = 100

4.- Determine how much less did Brian make than Tim.

90 - 50 = 40

5.- Conclusion

Brian made $40 less than Brian

I have 90 coins and I sold 15% of them. How many coins did I sell?

To do this problem, we could set up an equation by putting 15% into a decimal.

90 coins * 0.15 = amount of coins sold

13.5=amount of coins sold

You sold 13.5 coins.

The Ohio Department of Agriculture tested 203 fuel samples across the state in 1999 for accuracy of the reported octane level. F

Answer:

The Sample size is 1918.89035

Step-by-step explanation:

Consider the provided information.

It is given that 14 out of 105 samples failed.

Therefore p = 14/105 = 0.13 3... and q=1-0.133=0.867

Samples would be needed to create a 99 percent confidence interval.

Subtract the confidence level from 1, then divide by two.

$\frac{(1 -0.99)}{2}=0.005$

By standard normal table z=2.5758≈2.58

Calculate the sample size as:

$n=\frac{z^2pq}{e^2}$

Where, e is the margin of error,

Substitute the respective values.

$n=\frac{(2.58)^2(0.133)(0.867)}{(0.02)^2}=1918.89$

Hence, the Sample size is 1918.89035
