X-5/5+10
=x-1+10
=x+9. As a result, x+9 is your final answer. Hope it help!
After 401 flyers Company A has a better deal.
First it's important to note that, at 400 flyers they are equal.
39.99+0.5x=0.6x
-0.5x. -0.5x
39.99=0.1x
multiply both sides by ten
399.9=x
there can't be .9 flyers so round up to four hundred.
so, go one up (the easiest way to find which is larger after the part where they are equal) sorry this probably makes no sense... but
this is algebra. if this is to complex, try graph it. just use the cost for flyers as the x axis and the design as the initial cost so the y intercept.
but if u want to do it as an equation, just plug in 401 to both equations.
here are the equations I used from above:
company A- 39.99+0.5x
company B- 0.6x
I used a calculator for this part because it's easier. the second one had more. it was 240.6 for 401 flyers for the second one, and 240.49 for 401 flyers for the first. So... company A is actually cheaper at 401 and the more you purchase the better the deal will be compared to B.
I'm sorry if I explained that badly. just use a graph. lol
Complete Question
Although the first quarter of 2002 was quite dismal on Wall Street, mutual funds investing in gold companies rose an average of 35.2%. Assume that the distribution of returns in the first quarter of 2002 for mutual funds specializing in gold companies is fairly symmetrical with a mean of 35.2% and a standard deviation of 20%. If random samples of 16 gold stock funds were selected:
90% of the sample mean returns are between what two values symmetrically distributed around the mean?
Answer:
The two values symmetrically distributed around the mean are
21.87\% and 43.17\%
Step-by-step explanation:
From the question we are told that
The sample size is
The sample mean is
The standard deviation is
Generally the degree of freedom is mathematically represented as
=>
=>
From the question we are told the confidence level is 90% , hence the level of significance is
=>
Generally from the t distribution table the critical value of at a degree of freedom of is
Generally the margin of error is mathematically represented as
=>
=>
Generally 90% confidence interval is mathematically represented as
=>
converting to percentage
=>
Hence the 90% of the sample mean returns are between 21.87\% and 43.17\%

Answer:
x - 8y = - 56
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = x + 7
Multiply through by 8 to clear the fraction
8y = x + 56 ( subtract 8y from both sides )
0 = x - 8y + 56 ( subtract 56 from both sides )
- 56 = x - 8y, that is
x - 8y = - 56 ← in standard form
