Answer:
To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often.

In an isosceles triangle, the length of the base is half of the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
Answer:
10 cm, 20 cm, 20 cmStep-by-step explanation:
Let the base is x, then the legs are 2x each.
The perimeter is:
x + 2x*2 = 505x = 50x = 10The base is 10 cm and legs are 20 cm each.
Please include working out. =D You will get 30 points for it.
Answer:
It should be c
Step-by-step explanation:
Your formula is
Number of color ball/total ball
so 8/20 x 7/19 x 3/18 then convert to fraction
The probability the first ball is red is 0.4 or 8/20 or 2/5
The probability the next is blue is 7/19
The probability of the next being white is 6/18 or 1/3.
Multiply them together because these are independent events that must all occur and we get 2*7*1= 14 as the numerator
5*19*3=285 for a total probability of 14/285.
CHIGHWAYS Interstate 90 is the longest interstate highway in the United States, connecting the cities of Seattle, Washington, and Boston,
Massachusetts. The interstate is 4,987,000 meters in length. If 1 mile = 1.609 kilometers, how many miles long is Interstate 90?
Oa 3.099,441 mi
Ob. 3099 mi
Oc. 8,024,083 mi
O d. 8024 mi
=============================================================
Explanation:
4,987,000 meters = 4,987 kilometers
Divide by 1000 to go from meters to kilometers. This is because 1 km = 1000 m. Or in short, we just chop off those last three zeros at the end.
Also, because 1 mile = 1.609 km (approximate), this means we divide by 1.609 when converting from km to miles
So,
4,987 km = 4987/(1.609) = 3,099.4406 miles approximately
This rounds to 3099 miles
----------------
You can optionally show your work like this:
[tex]4,987,000 \text{ m} * \frac{1 \text{ km}}{1000 \text{ m}}*\frac{1 \text{ mi}}{1.609 \text{ km}}\\\\ = \frac{4,987,000*1*1}{1000*1.609} \text{ mi} \\\\\approx 3099.4406 \text{ mi}\\\\ \approx \textbf{3099 mi}[/tex]
Notice that the "km" and "m" units cancel out when going from the first step to the second step. All that's left is the "mile" unit.

Not enough information
Answer:
non-proportional
Step-by-step explanation:
The line doesn't go through the origin and it's not a straight line therefore the graph is not proportional. Hope this helps :)
Answer:
Not proportional
Step-by-step explanation:
The graph is not proportional because the line doesn't go through the origin. If the line start from the origin and went up it would be a proportional graph.

A. y=5.5x+6.75
B.y=13.5x-1.25
C.y=13.5x+12.25
D.y=6.75x+5.5
Answer:
D. y = 6.75x + 5.5Step-by-step explanation:
The slope intercept form:
y = mx + b, where m- slope, b- y-interceptUse two ordered pairs from the table and work out the equation.
(1, 12.25) and (3, 25.75)Find the slope:
m = (y₂ - y₁)/(x₂ - x₁)m = (25.75 - 12.25)/(3 - 1) = 13.5/2 = 6.75Find the y- intercept:
12.25 = 6.75*1 + bb = 12,25 - 6.75b = 5.5The equation is:
y = 6.75x + 5.5Correct choice is D
Slope

Hello there!
When we are given the graph of a line and two points on the graph, we can calculate the slope of the line using Rise/Run.
Rise=How many units we move up (here, the rise is 3)
Run=How many units we move left or right (Here, the run is 5)
So the slope of this line is [tex]\frac{3}{5}[/tex]

Given the vertex ( 4, 6 )and the point(1, -3), write the vertex form equation of the quadratic
function.
Answer:
[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]
Step-by-step explanation:
A given quadratic has its vertex at (4, 6) and the point (1, -3). We want to write the equation in vertex form of the quadratic.
Recall that vertex form is given by:
[tex]\displaystyle f(x) = a(x-h) ^2 + k[/tex]
Where (h, k) is the vertex and a is the leading coefficient.
Since our vertex is at (4, 6), h = 4 and k = 6:
[tex]\displaystyle f(x) = a(x - 4)^2 + 6[/tex]
To determine the leading coefficient, since we are given that (1, -3) is a point on the parabola, when x = 1, y = -3. Substitute and solve for a:
[tex]\displaystyle \begin{aligned} (-3) & = a((1)-4)^2 + 6 \\ \\ -3 & = a(-3)^2 + 6 \\ \\ 9a & = -9 \\ \\ a & = -1 \end{aligned}[/tex]
Hence, the leading coefficient a is -1.
Then our equation in vertex form is:
[tex]\displaystyle f(x) = -(x-4)^2 + 6[/tex]
5. A w-foot wide path is to be built around a rectangular space that is 80
feet by 50 feet. Write and simplify an expression for the total area.
To find the area of the path, we'll need to find the area of the space with the path and subtract the area of the inner space.
Total area: (80 + w)(50 + w)
Inner area: 80 x 50
Area of the path: (80 + w)(50 + w) - (80 x 50)
(4000 + 80w + 50w + w^2) - (4000)
4000 + 130w + w^2 - 4000
w^2 + 130w
w(w + 130)
Expression for the total area: (80 + w)(50 + w)
Expression for the area of the path: w(w + 130)

Miguel Ponce has P1,500.00 cash. If he bought a pair of shoes for P1,325.00, what is the percent of the remaining cash he has left?
Answer:
Step-by-step explanation:
Cash remaining=P1, 500.00-P1,325.00
=P175
Percent of the remaining cash= Cash Remaining × 100
Cash he originally had
= P175 × 100
P1 500
=11[tex]\frac{2}{3}[/tex] %or 11.6666666% or 11.67% when rounded to two decimal places.
A percentage is a way to describe a part of a whole. The percent of the remaining cash he has left is 11.667%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Value of the Remaing Cash = P1,500.00 - P1,325.00
= P175.00
Now, the percent of the remaining cash he has left can be written as,
Percentage of remaining cash = (Remaining cash/ Total cash) × 100%
= (P175.00 / P1,500.00) × 100%
= 0.011667 × 100%
= 11.667%
Hence, the percent of the remaining cash he has left is 11.667%.
