The Ohio Department of Agriculture tested 203 fuel samples across the state in 1999 for accuracy of the reported octane level. F
OlgaM077 [116]

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

<u>Answer</u>:

13. 6x^7 y^7   ||     14. \frac{25x^4}{y^6}

<u>explanation</u>:

13.

\frac{12x^9 y^5}{2x^2 y^-2}

6x^{9-2} y^{5--2}

6x^7 y^7

14.

(\frac{5y^{-3} }{x^{-2} } )^{2}

(\frac{5y^{-3} }{x^{-2} } )(\frac{5y^{-3} }{x^{-2} } )

\frac{\frac{25}{y^6}}{\left(x^{-2}\right)^2}

\frac{\frac{25}{y^{-6} }}{\left(x^{-4}\right)}

\frac{25x^4}{y^6}

I need help. Work has to be shown but i don’t know how to do them
mote1985 [20]

Step-by-step explanation:

1.

1% of 500 is 5 so multiply 5 by 8 for one year. which is 40 so multiply that by 2.

1% of 500 = 5

5 × 8 = 40

40 × 2 = 80

2.

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

3.

12 months = 6%

6/12 = 1 month

0.5 = 1 month

0.5 × 9 = 4.5 (the amount of interest for 9 months.)

800 × 4.5% = 36

4.

12 months = 7%

7/12 = 1 month ( i'll leave this in fraction form because of the decimal points.)

7/12 x 8 = 4.666667 or 4.7 rounded.

1200 × 4.7% = 56.40
