Answer:
Step-by-step explanation:
Given that,
The base of a triangle = 2 km
The perpendicular height of the triangle = 
We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :
So, the value of x is equal to 
.
Answer:
(2,3)
Step-by-step explanation:
use the equal values method.
set y equal to itself.
y = -2x+7 but also 5x-7
-2x+7=5x-7 ............................. solve the equation
7x=14
x=2
Now substitute the x value into one of the equations given. for example i'll do -2x+7.
-2(2) +7 =y
-4+7=y
3=y
so thats your answer
x=2, y=3
(2,3)
The y intercept is 3 because the line intercepts the y axis at 3.

According to the hypothesis test, the correct statement of the p-value is mean value is against null hypothesis.
Hypothesis test:
In statistics, hypothesis test means a form of statistical inference that uses data from a sample to draw conclusions about a population parameter or a population probability distribution.
Given,
Here we need to find the correct statement of the p-value for the a hypothesis test for population proportion, you calculated the p-value is 0. 01 for the test statistic.
While we looking into the given question we have identified the value of p value of the test statistic is 0.01.
Then the correct statement of the p-value less than 0.01 will under normal circumstances mean that there is substantial evidence against the null hypothesis.

Step-by-step explanation:
5. Let the equation of the line be y = mx + c
m = (6-15)/(2-(-1)) = -3
sub (2, 6) and m = -3:
6 = -3(2) + c
c = 12
Equation of the line: y = -3x + 12
6. Let the equation of the line be y = mx + c
y-intercept of 7 means c = 7
y = mx + 7
x-intercept: value of x when y = 0
therefore, sub (4, 0):
0 = m(4) + 7
m = -7/4
Equation of the line: y = -7/4x + 7
