x - 3 < -5
add 3
x < -2
Answer:
$390+0.07s=$544+0.05s Subtract $390 from each side.
0.07s=$154+0.05s Subtract 0.05s from each side.
0.02s=$154 Divide each side by 0.02.
s=$7700 Both plans pay the same when sales=$7700
ANSWER With sales greater than $7700, Chris is better off with Plan A.
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).

The area is 270 inches, because you would do length times width, which in this situation is 28 and 15. You multiply them, and you get 270.
Answer:
x=1
Step-by-step explanation:
1) multiply the numbers
2) combine multiplied terms into a single fraction
3) distribute
4) combine fractions with common denominator
5) combine like terms
6) multiply all terms by the same value to eliminate fraction denominators
7) cancel multiplied terms that are in the denominator
8) multiply the numbers
9) add 35/4 to both sides of the equation
10) simplify
( add the numbers twice)
11) divide both sides of the equation by the same term
12) simplify
(divide the numbers, cancel terms that are in both the numerator and denominator, and last but not least move the variable to the left)
well and behold your answer is x=1
