Hey there! :)
Answer:
x = -4.
Step-by-step explanation:
We can write an algebraic equation to express this situation.
Let 'x' represent a number:
4(2x + 6) = -8.
Begin by dividing both sides by 4:
2x + 6 = -2
Subtract 6 from both sides:
2x + 6 - 6 = -2 - 6
2x = -8
Divide 2 from both sides:
2x/2 = -8/2
x = -4.
Answer:
non-proportional
Step-by-step explanation:
non-proportional because it doesn't pass through the origin.
Answer:
The projected annual sales of Satelite Corporation are $ 161,805.
Step-by-step explanation:
Given that Satellite Corporation projects a year-end net income of $ 64,722, and that the net income represents 40% of its projected annual sales, to determine the amount of the projected annual sales of the company the following calculation must be performed:
40 = 64.722
100 = X
(100 x 64,722) / 40 = X
6,472,200 / 40 = X
161.805 = X
Therefore, the projected annual sales of Satelite Corporation are $ 161,805.
Answer:
Sample size n = 1382
so correct option is D) 1382
Step-by-step explanation:
given data
confidence level = 99 %
margin of error = 3%
probability = 25 %
to find out
How large a sample size needed
solution
we know here P = 25 %
so 1 - P = 1 - 0.25
1 - P = 0.75
and we know E margin of error is 0.03 so value of Z for 99%
α = 1 - 99% = 1 - 0.99
α = 0.01
and =
= 0.005
so Z is here
= 2.576
so
sample size will be
Sample size n =
put here value
Sample size n = (\frac{2.576}{0.03})^2 * 0.25 * 0.75
Sample size n = 1382
so correct option is D) 1382
