Answer:
Step-by-step explanation:
Given AB with coordinates A(3, -3) and B(1, -1)
Perpendicular bisector passes through midpoint of the segment.
<u>Midpoint of AB has coordinates:</u>
- x = (3 + 1)/2 = 2, y = (-3 - 1)/2 = -2
<u>Slope of AB</u>
- m = (-1 + 3)/(1 - 3) = 2/-2 = -1
<u>Slope of the perpendicular line is:</u>
<u>The equation of the line in point-slope form:</u>
- y - y₁ = m(x - x₁), where m = 1, x₁ = 2, y₁ = -2
- y - (-2) = 1(x - 2) ⇒ y + 2 = x - 2
<u>Converted into slope-intercept form:</u>
Answer:
a ) 400 percent
b ) n = 25
c) n= 36
Step-by-step explanation:
Is means equals, of means multiply and percents need to be changed to decimals.
a) 120 is what percentage of 30
120 = P * 30
Divide each side by 30
120/30 =P* 30/30
4 = P
Multiply by 100 to give the percentage
4 * 100
400 percent
b) 30 is 120% of what number
30 = 1.2 * n
Divide each side by 1.2
30/1.2 = 1.2n/1.2
25 = n
c) what number is 30%of 120
n = .3 * 120
n =36
The answer is (2,4), my work :
Two possible questions are:
- How many black shoes did the private company donate.
- What is the total cost of the black shoes donated to the private company?
<h3>What are the two questions?</h3>
The appropriate questions are questions that can be solved using either statistics or mathematical operation.
For example, In order to determine the total cost of the donation, the total shoes donated would have to multiplied by the cost per shoe.
Here is the complete question?
Directions: Read and analyze the situation below and write 2 possible
questions problems which you think can be solved using statistics.
1. A private company wanted to donate black shoes for the students for
the upcoming school year.
