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

A local hamburger shop sold a combined total of 500 hamburgers and cheeseburgers on Wednesday. There were 50 more cheeseburgers

Komok [63]

500-250=250 so if there were 50 more cheeseburgers it would be 300 cheeseburgers so they would of have to sold 200 hamburgers on Wednesday to have sold 500 burgers in total do the answer is 200 hamburgers

SOMEONE HELP ME PLEASE WITH THESE PROBLEMS AND PLEASE SHOW YOUR WORK FOR 50 points and BRAINLIEST THANK YOU

ELEN [110]

<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% 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

1% of 1000 = 10

10 × 5 = 50

50 × 3 = 150

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

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
