The answer is $113 because you add the money
Using the z-distribution, the 99% confidence interval to estimate the population proportion is: (0.2364, 0.4836).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 99% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 2.575.
The estimate and the sample size are given by:
.
Then the bounds of the interval are:
The 99% confidence interval to estimate the population proportion is: (0.2364, 0.4836).

Let the first number be x and decide number be y
therefore x+y = -42
also. x-y = 52 using the process of elimination
we get: 2x = 10
we divide both sides by 2, which gives us x=5
then we substitute the value of x in the first equation
that gives us. 5+y = -42
thus. y = -47
Answer:
130
Step-by-step explanation:
If you replace the value of c with 130, you can multiply 13 with 130 to get your answer.
13 x 130 = 1690
Or, you can multiply 13 with 13 and add the 0 onto the end. This makes the same answer. To add a zero onto the end of a number multiply it by ten.
169 x 10 = 1690
S<span>o is it saying what is the monthly fixation charge ? if it is the answer would be </span><span>if it's 500 minutes for $5 so fixed cost would be $30
cost = $30 + $5 * the number of mins divided by 500
Hope this helps
