Step-by-step explanation:
apothem (AB)
1/2 of the length (10) is 5
AB^2 + 5^2 = 10^
AB^2 = 100-25
Square root of AB^2 = square root of 75

How many pairwise comparisons must you make for a case with 15 statistically independent scenarios?
There are 105 comparisons made with 15 statistically independent scenarios.
According to the statement
we have given value of n is 15.
Then r = 2. so,
we use the formula NcR then
Substitute the values in it then
15c2
we open it according to ncr formula
In this formula we arrange the terms according to the following
NcR formula = n! /r! * (n-r)!
then the terms will arrange in this way.
So,
ncr = 15! / 2! * 13!
After solving the statement some terms will be cancel with each other and remaining terms are
ncr = 15*14/2
ncr = 210/2
ncr = 105
here the value becomes 105.

A rectangular park is 70 meters wide and 120 meters long. Give the length and width of another rectangular park that has the same perimeter but a smaller area.
Answer:
1 m by 189 m
Step-by-step explanation:
The perimeter is 2(70+120)=380.
The area is (70)(120)=8400.
If we let the park have a width of 1 meter and a length of 189 meters, then the area will be 189 square meters, which is smaller than 8400 square meters, as required.
sutopa has 3/4 the money maneet has. maneet has $18 less than Kim. together, they have $286.40. How much money does each of them have?
The amount of money Kim, maneet and Sutopa have is $115.6, $97.6 and $73.2 respectively.
EquationKim = xManeet = x - 18Sutopa = 3/4(x-18)Total = $286.40x + (x - 18) + 3/4(x-18) = 286.40
x + x - 18 + 3/4x - 13.5 = 286.40
2 3/4x = 286.40 + 13.5 + 18
11/4x = 317.9
x = 317.9 ÷ 11/4

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Point B is 3/4 of the way from AB to AC, hence:
[tex]B - A = \frac{3}{4}(C - A)[/tex]
The points are:
A(-2,-3).B(x,y).C(3,1).
Then, to find the x-coordinate:

Find equation of the line passing through the point (-1,0) and parallel to the line y=-1/2x + 3/7
Answer:
Step-by-step explanation:
A parallel line will have the same slope, m, as the reference line given by the form y=mx+b. b is the y-intercept, the value of y when x=0.
The reference line of y = -(1/2)x + (3/7) has a slope of -(1/2).
The parallel line will have the same slope, so we can write:
y - -(1/2)x + b
We need a value of b that forces the line to go through point (-1,0). Enter that point in the equation and solve for b:
y - -(1/2)x + b
0 - -(1/2)(-1) + b
b = -(1/2)
The equation of the line parallel to y = -(1/2)x + (3/7) and going through (-1,0) is
y=-(1/2)x - (1/2)

What is a linear equation in math?
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.I spent a dollars at American Eagle, which is 4 more than the amount I spent at Banana Republic ( b ).
a = b + 4. Therefore: b = a - 4
Also I spent 15 less at American Eagle than I spent in Cole Haan ( c ).
a = c - 15, or: c = a + 15.
75 - a - ( a - 4 ) - ( a + 15 ) = 75 - a - a + 4 - a - 15 =

Which theorem correctly justifies why the lines m and n are parallel when cut by a transversal k
The theorem which justifies that two lines are parallel when cut by a transversal k is converse of the alternate interior angles theorem.
Given that two lines m and n are parallel.
We have to find the theorem which justifies that the lines m and n are parallel when cut by a transversal k.
Parallel lines are those lines which do not meet each other at any point on the surface.
If we know that the alternte interior angles are equal,then m and n become parallel to each other.
So the converse of the alternate interior angles theorem correctly justifies that the lines are parallel if cut by a transversal k.
Hence to justify that two lines are parallel if they are cut by a transversal k, we have to use converse of the alternate interior angles theorem.

If (x + 1)(x-3) = 5, then which of the following statements is true?
Ox+1=0 orx-3=0
Ox+1=5 orx-3=5
Ox-4-0 orx+2=0
Answer:
(x-4)=0 or (x+2)=0 is correct
Step-by-step explanation:
(x+1)(x-3)=5
x^2 -3x +x -3=5
x^2-2x-8=0
x^24x+2x-8=0
(x+2)(x-4)=0
so,
(x-4)=0 or (x+2)=0
The solutions to the expression are:
x - 4 = 0 or x + 2 = 0.
Option C is the correct answer.
We have,
To determine which of the following statements is true:
(x + 1) = 0 or (x - 3) = 0
(x + 1) = 5 or (x - 3) = 5
(x - 4) = 0 or (x + 2) = 0
We can solve the given equation (x + 1)(x - 3) = 5 by expanding the equation and setting it equal to 0:
(x + 1)(x - 3) - 5 = 0
Expanding the equation:
x² - 3x + x - 3 - 5 = 0
x² - 2x - 8 = 0
Now we can factor the quadratic equation:
(x - 4)(x + 2) = 0
From this factorization, we find two possible solutions:
x - 4 = 0 --> x = 4
x + 2 = 0 --> x = -2
Therefore,
The correct statement is:
(x - 4) = 0 or (x + 2) = 0
i.e
x - 4 = 0 or x + 2 = 0.
