Subtract 7x from 8x then add 25 to 5 then divide what you get when you subtract 7 from 8 by what you get when you add 25 to 5 and that's your answer ( add x to the answer).

7x + 5 = 8x - 25
- 5 = -8x -5
-------------------------------
7x - 8x = - 5 - 25

-1x = - 30
----- -------
-1 -1

x = 30

The director of the library calculates that 29% of the library's collection is checked out. If the director is right, what is th

marusya05 [52]

Answer:

The probability that the proportion of books checked out in a sample of 412 books would differ from the population proportion by less than 4% is P=0.9255.

Step-by-step explanation:

The population's proportion is $\pi=0.29$

If we take a sample of 412 books (n=412), we have a standard deviation of the sampling distribution of:

$\sigma_M=\sqrt{\frac{\pi(1-\pi)}{n}}=\sqrt{\frac{0.29*0.71}{412}}=\sqrt{0.0005} =0.0224$

We have to calculate the probabilty that the sample proportion will be between 0.25 and 0.33.

$z_1=(0.25-0.29)/0.0224=-0.04/0.0224=-1.7857\\\\z_2=1.7857\\\\\\P(0.25$

aliya0001 [1]

Answer: 429.88

Step-by-step explanation:

The first 40 hours is at 9.50

40 *9.50 =380

The remaining hours is at 9.50 * 1.5 or 14.25

43.5 -40 = 3.5

3.5 * 14.25

49.875 = 49.88 ( rounding to the nearest cent)

Add together

380+49.88 =429.88
