Answer:
You're wrong, the answer is C) 24
Explanation:
4d/h when b=3, d=12, h=2, r=7
Plug in the variables --> 4(12)/(2)
PEMDAS says do 4*12 first so --> 48/2
Which is 24.
Using the information given and the z-distribution, it is found that:
a) The point estimate of the population proportion is 0.5544.
b) The margin of error is: 0.0320.
c) The interval is: (0.5224, 0.5864).
d) The interpretation of the interval is: we are 95% sure that the true population proportion is between 0.5224 and 0.5864.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions has the bounds given by the rule presented as follows:
In which the variables used to calculated these bounds are listed as follows:
- is the point estimate of the population proportion.
The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of , so the critical value is z = 1.96.
From the sample, the sample size and the point estimate are given as follows:
The margin of error is given by:
M = 0.0320.
The interval is the point estimate plus/minus the margin of error, hence:
- Lower bound: 0.5544 - 0.0320 = 0.5224.
- Upper bound: 0.5544 + 0.0320 = 0.5864.

Answer:
Drugs whether it's medication or for your own use, it can be become dangerous. It can affect the way your body and mind function; changing how you feel, think and behave. It can become a huge social problem because people mostly think it only affects the person using it. However, that's not the case. It can create a domino effect on the lives of those around the user. It is a social problem that normalizes drug use and affects individuals and their families.
Hope this helps! :)

Ok, so first you have to count le 15% off. It means you pay 85% of the price
0,85•65= 55,25$
Second, you take the 10$ off
55,25-10=45,25$
Third, you have know what percentage of the original price you paid
45,25 divided by 65 =0,6962
So you actually paid 69,62% of the original price
