So all you have to do is multiply 400 times 400 which is 160,000 and divide 169,000 to 2 which is 80,000
Step-by-step explanation:
1.) Plug in one of the points.
y = 8x + b
6 = 8(4) + b
2.) Solve for b (or [?])

32 cancels out on the right side.
Subtract 32 from 6, which is -26
3.) -26 = b
4.) Check with other point:
-2 = 8(3) + b
-2 = 24 + b
Cancel out 24 on the right side: 24-24 = 0
-2 - 24 = -26
-26 = b
Answer:
The answer is "12 inches".
Step-by-step explanation:
Please find the image file of the graph.
We know
so because the triangle is isosceles.
when
is called by
.
We know that
since E and D are tangent points to a circle.
They have
since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:

Therefore the length of 
Let h = height of triangle
h^2 + 12^2 = 15^2
h^2 + 144 = 225
h^2 = 225 - 144
h^2 = 81
sqrt{h^2} = sqrt{81}
h = 9 cm
For part B, we need to find surface area because it represents the perimeter of this 3-D figure. The formula needed is SA = B + LA.
1. First find the lateral area.
LA = perimeter of triangle • height
LA = ph
p = 15 + 15 + 24
p = 30 + 24
p = 54 cm
LA = (54)(9)
LA = 486 cm^2
2. We now find the base of each triangle. This is found by finding the area of each triangle and multiplying by 2.
A = (1/2)bh
A = (1/2)(24)(9)
A = 108 cm^2
A = 2•108 cm^2
A = 216 cm^2 = our B in the surface area formula.
SA = B + LA
SA = 216 cm^2 + 486 cm^2
SA = 702 cm^2
The amount of cardboard needed is 702 cm^2.
Answer: The value of test statistic is -0.052.
Step-by-step explanation:
Since we have given that
n = 677
and

Claim that Most of the adults erase all of their personal details online.
p = 0.5
q = 1-0.5 = 0.5
So, the test statistic would be
