Answer:
The slope of the perpendicular line to the line is
m =
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the line y =f(x) = 2x +6
⇒ y = 2x +6
comparing y =mx +c
The slope of the given line m =2
<u><em>Step(ii):- </em></u>
The slope of the perpendicular line =
The slope of the perpendicular line =
Answer:
8 portraits are going to be used in the display.
Step-by-step explanation:
This problem can be solved as a rule of three problem.
Each yd has 36 inches.
The display is to span a total width of 10 yd. So it is a total width of 360 inches.
Each portrait has a width of 45 in. How many portraits can there be?
1 portrait - 45 in
x portraits - 360 in
8 portraits are going to be used in the display.
Answer:
0.0417
Step-by-step explanation:
Given the following;
p = 0.7, n=121
The sampling distribution of sample proportion will be approximately normal with mean
\mu_{\hat{p}}=p=0.7
and standard deviation
\sigma_{\hat{p}}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.7\cdot 0.2}{121}}=0.0417
