A 250 ml bottle of water treatment liquid will treat up to 625 litres of water. Given that 1 cubic meter=1000 litres, how much treatment liquid is needed to treat a water tank of 224m cubed when full. Please show workings. Many thanks

Answers

224 m cubed corresponds to:
224×1000=224,000 liters of water in your water tank.
Each bottle of liquid can treat 625 liters of water so you need:
224,000/625=358.4 bottles (a little bit less than 358 and a half bottle) corresponding to:
358.4×250=89,600 ml of treatment liquid.

so 224 cubic meters=224 times 1000 liters=224000 leters

so

250 ml=625 leter
divide 250 by 625 to find how many ml per liter
250/625=0.4
therefor
0.4ml=1 leter treted

so

224000 leters
0.4 ml per liter
224000 times 0.4=89600 ml total
89600=89.6 liters

total is 89600 ml or 89.6 liters

Step-by-step explanation:

A population has a mean of 300 and a standard deviation of 70. Suppose a sample of size 125 is selected and is used to estimate . Use z-table. What is the probability that the sample mean will be within +/- 8 of the population mean (to 4 decimals)? (Round z value in intermediate calculations to 2 decimal places.) What is the probability that the sample mean will be within +/- 17 of the population mean (to 4 decimals)? (Round z value in intermediate calculations to 2 decimal places.)

Answers

Following are the calculation to the given points:

Using central limit theorem:

$\to \mu_{\bar{x}}= \mu = 300\n\n\to \sigma_{\bar{x}}=(\sigma)/(√(n))=(70)/(√(125))= 6.261\n\n$

For point a)

Within $\pm 8$ population mean: $\to P(\mu-8<\bar{x}<\mu+8)=P\left ( (\mu-8-\mu)/(6.261)Within [tex]\pm 17$

For point b)

Within $\pm 17$ population mean:

[tex]\to P(\mu-17<\bar{x}<\mu+17)=P\left ( \frac{\mu-17-\mu}{6.261}

Final answer:

To find the probability that the sample mean will be within a certain range, we need to calculate the z-scores and look them up in the z-table.

Explanation:

To find the probability that the sample mean will be within +/- 8 of the population mean, we need to convert this range to z-scores. The z-score formula is calculated by subtracting the population mean from the sample mean and dividing by the standard deviation divided by the square root of the sample size.

For +/- 8, the z-score will be (8 - 0) / (70 / sqrt(125)) = 2.09.

Using the z-table, we can find the probability associated with a z-score of 2.09, which is approximately 0.9828. Therefore, the probability that the sample mean will be within +/- 8 of the population mean is 0.9828.

Similarly, for +/- 17, the z-score will be (17 - 0) / (70 / sqrt(125)) = 4.18. Using the z-table, the probability associated with a z-score of 4.18 is nearly 1.0000. Hence, the probability that the sample mean will be within +/- 17 of the population mean is 1.0000.

If necessary, use / for the fraction bar(s).James bought two T-shirts and one pair of jeans at an online store and paid $40, not including taxes, for his purchase. A month later, the same store sold the T-shirts and jeans at a 50% discount from their original prices. James bought two T-shirts and five pairs of jeans for $60, not including taxes.
Assuming the base prices of the T-shirts and the jeans are the same on both occasions, and ignoring the taxes, the price of a T-shirt is $ and the price of a pair of jeans is $.

Answers

Call T the price of the T-shirts and P de price of the jeans

Initially (without discount)
2T + P = 40

One month later (half prices)
2 (T/2) + 5(P/2) = 60
T +5P/2 = 60

To solve the system of equations multiply the second equation by 2 and substract it from the first equation

   2 T + 5P = 120
- (2 T +   P = 40 )
________________

   4P = 80

P = 80/4
P = 20

From 2T + P = 40

T = (40 - P) / 2 = (40 -20) / 2 = 20/2 = 10.

The price of a T-shirt is $10 and the price of a pair of jeans is $20.
