Your school is 4 miles east and 1 mine south of your apartment there is a park 3 miles east and 4 miles south of your apartment estimate the distance between the park and your school
The estimated distance between the park and your school is 5 miles.
Here,
To estimate the distance between the park and your school, we can use the Pythagorean theorem, as the distance forms a right-angled triangle with the school, apartment, and park as its vertices.
Let's label the points as follows:
S = School
A = Apartment
P = Park
Given:
School (S) is 4 miles east and 1 mile south of the apartment (A).
Park (P) is 3 miles east and 4 miles south of the apartment (A).
Now, we have two right-angled triangles:
The triangle formed by S, A, and P. This is the triangle for which we want to estimate the distance between the school and the park.
The triangle formed by A, S, and P.
Since both triangles share the side AS (4 miles east), we can use the Pythagorean theorem for the triangle ASP to find the distance between the school and the park.
The Pythagorean theorem states that for a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, let's represent the distance between the school and the park as d (the hypotenuse), and the other two sides as 3 miles (east) and 4 miles (south).
Using the Pythagorean theorem:
[tex]d^2 = 3^2 + 4^2\\d^2 = 9 + 16\\d^2 = 25\\[/tex]
Now, take the square root of both sides to find d:
d = √25
d = 5
So, the estimated distance between the park and your school is 5 miles.

To find the distance between (17,3) and (17,−5), Marcia used the following equation. Is Marcia correct? Explain. D=|3−(−5)|=8
Answer:
Step-by-step explanation:
The formula for finding the distance between two points is expressed as shown
D = √(x₂-x₁)²+(y₂-y₁)²
Given the coordinate (17,3) and (17,−5), from the coordinates x₁ = 17, y₁ = 3, x₂ = 17 and y₂ = -5.Substituting the values given into the formula;
D = √(17-17)²+(-5-3)²
D = √0²+(-8)²
D = √64
D = 8
According to the result gotten, it can concluded that Marcia is correct although she didn't use the right expression to calculate her distance. She should have taken the square root of the sum of the square of difference in the coordinates axis according to the formula used.
Rodney rented a machine for $70.00 to make popcorn at a school event. In addition to the machine rental cost, the popcorn supplies cost him $0.15 per bag sold. Rodney sold popcorn for $1.00 per bag how much profit did rodney make if he sold 200 bags of popcorn
Answer:
170
Step-by-step explanation:
The amount of profit Rodney made when he sold 200 bags of popcorn is given by A = $ 100
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the equation is
Let the amount for renting the machine be = $ 70
The amount per bag for packing popcorn = $ 0.15 per bag
The sale price of the popcorn per bag = $ 1.00
And ,
The total number of bags sold by Rodney = 200 bags
So , the total profit made by Rodney A is calculated from the equation ,
Total amount made by Rodney = total number of bags sold by Rodney x sale price of the popcorn per bag
Substituting the values in the equation , we get
Total amount made by Rodney = 200 x 1
Total amount made by Rodney = $ 200
Now , the cost per bag is deducted from the total amount made by Rodney
So ,
Total amount made by Rodney after deduction of bag cost = ( Total amount made by Rodney - amount per bag for packing popcorn x 200 )
Substituting the values in the equation , we get
Total amount made by Rodney after deduction of bag cost =
= 200 - ( 0.15 x 200 )
= 200 - 30
= $ 170
Now , the cost of renting the machine should also be deducted from the remaining amount to calculate the profit earned by Rodney
So , The profit earned by Rodney A = 170 - amount for renting the machine
The profit earned by Rodney A = $ 170 - $ 70
The profit earned by Rodney A = $ 100
Therefore , the value of A is $ 100
Hence , The amount of profit Rodney made when he sold 200 bags of popcorn is given by A = $ 100

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (w.y) be the unknown endpoint. Apply the midpoint formula, and solve the two equations for x and y)
midpoint (2.2), endpoint (1. - 2)
The other endpoint is
Answer:
(3,6)Step-by-step explanation:
Given two coordinates (x₁,x₂) and (y₁,y₂), their midpoint (w,y) is expressed as:
M(X,Y) = [tex](\dfrac{x_1+w}{2}, \dfrac{y_1+y}{2})[/tex]
From the question, we are given the midpoint (X,Y) to be (2,2) and one endpoint as (1, -2) and we are to find the other end point expressed as (w,y). From the coordinates given, i can be seen that X = 2, Y =2, x₁ = 1 and y₁ = -2
Substituting the given end points into the given formula to get the other end points, we will have;
[tex]X = \dfrac{x_1+w}{2} \\2 = \dfrac{1+w}{2} \\cross\ multiply\\4 = 1+w\\w = 4-1\\w = 3[/tex]
Similarly;
[tex]Y = \dfrac{y_1+y}{2} \\2 = \dfrac{-2+y}{2} \\cross\ multiply\\4 = -2+y\\y = 4+2\\y = 6[/tex]

3. Kay owns a small business that employees 6 other people. Kay makes $90,000 per year, and the other 6 employees make between $45,000 and $60,000 per year. Kay decided to increase her salary by $20,000 and leave the rest of the salaries the same. How will increasing her salary affect the mean and median?
• Both the mean and median will increase .
• The mean will increase, and the median will stay the same.
• The median will increase, and the mean will stay the same.
• The mean will increase, and the median will decrease.
Answer: B) The mean will increase and the median will stay the same.
======================================================
Explanation:
Let's look at a small example of why this works.
Suppose that we had the set of 5 items {1,2,3,4,5}. The value 3 is right in the middle so this is the median. The mean is also 3 because adding all the values gets us 15 and then we divide over 5 (the number of items in the set) to get 15/5 = 3.
For any symmetric set of data like this, the mean and median are the same value.
Now let's change that last item 5 to something larger. Let's bump it up to 10
The new data set is {1,2,3,4,10}. The median is still 3 as it's still in the middle. But now the mean is (1+2+3+4+10)/5 = 20/5 = 4. The old mean was 3, and the new mean is 4. So we have the mean increased thanks to that 5 increasing to 10.
We could increase 10 to 20 getting {1,2,3,4,20}. The median is still the same. The mean is now (1+2+3+4+20)/5 = 30/5 = 6. So we've increased the mean again. This process can be continued on for as long as you like.
The outliers to the right hand side effectively pull on the mean in a similar analogy to how gravity pulls on an object. So this is one way to remember that the mean is effected by outliers. The median only cares about being in the middle so that's why it doesn't change. If we changed the number of items in the data set, then it's a different story. However, Kay is only changing her salary rather than bring on a new hire (or two).
So that small example can be applied to Kay's situation even though the numbers are much larger. The median stays the same, but Kay's (much) higher salary pulls on the mean to make it larger than it should be. This is often why a trimmed mean is used when looking at centers of data sets. For data sets that have very large outliers, the median is the more reliable measure of center.

A floor 5 m by 20 m is covered by square tiles of side 20 cm. How many tiles are needed
Answer:
number of tiles needed = 2500 pieces
Step-by-step explanation:
Floor area = 5m x 20m = 100 m²
area of 1 square tile = 20cm x 20cm = 400 cm² ---- convert to m²
400 cm² x [tex]\frac{1 m^{2} }{100^2 cm^2}[/tex] = 0.04 m²
To get the number of tiles required to cover the floor area 5x20 = 100 m²
just divide it by the area of tile.
so Number of tile req'd = 100 / 0.04 = 2500
therefore,
the number of tiles needed = 2500 pieces
