The answer is <span><span>−<span>6<span>x2</span></span></span>+<span>7x</span></span>−<span>212</span>
y = 7 + 3x
y = 3x + 7
y = mx + b, therefore the y-intercept is 7.
3y = 6x + 12
y = 2x + 4
y = mx + b, therefore the y-intercept is 4.
First move the terms to get
6m-m=13+2
Then collect the like terms and calculate the sum, 5m=15
Divide both sides by 5
And you get m=3
A = x * x = x^2
B = 6 * x = 6x
C = 8 * x = 8x
D = 6 * 8 = 48
So the area of the whole shape is each side added up then multiplied to give (x+6)(x+8) =
x^2 + 14x + 48
Answer:
The statistic for this case would be:
And replacing we got:
Step-by-step explanation:
For this case we have the following info:
represent the sample size
represent the number of employees that earn more than 50000
We want to test the following hypothesis:
Nul hyp. 
Alternative hyp : 
The statistic for this case would be:
And replacing we got:
And the p value would be given by:
