Answer:
To find x, y, z, p and q, you need to know about the property of Rhombus.
13y + 10 = 7y + 16 (pair of equal opposite sides)
=> 6y = 6
=> y = 1
x = 7x + 16 (2 equal adjacent sides)
= 7*1 + 16
=23
z = 90 deg (angle between 2 diagonals)
q = 22 deg (isosceles triangle)
p = 90 - 22 = 68 deg (right triangle)
1. Use substitution to create a one-variable linear equation: -3= 4x - 5.
2. Solve to determine the value of the unknown variable.
3. Write the solution to the system of equations as an ordered pair.
The solution to the system is (
-3).
Intro
3 of 15
Answer:
x = 1/2
Step-by-step explanation:
-3= 4x - 5 becomes 5 - 3 = 4x when 5 is added to both sides. Then:
2 = 4x, and x = 2/4, or x = 1/2.
The solution of the linear equation -3= 4x - 5 is x = 1/2.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
An equation: -3 = 4x - 5.
Simplifying,
by using substitution,
4x - 2 = 0
This is a one variable linear equation. Where x is a variable.
In order to solve the equation:
Simplifying,
4x = 2
x = 1/2
Therefore, the solution of the equation is 1/2.

At Ken's boutique, 33 customers wore a size small, and 51 customers wore a different size.
What is the probability that a randomly selected customer wore a size small?
Write your answer as a fraction or whole number.
Answer:
11/28
Step-by-step explanation:
1. Add up all of the customers to get the sample size.
33 + 51 = 84
2. Since we are finding the chance of it being a size small, 33 will be out numerator.
3. Create the final fraction, (33/84)
4. Simplify (11/28)
Hope this helps! Comment if you have any questions. :)
Answer:
11/28
Step-by-step explanation:
First, you add 33 and 51 to get a total of 84 customers. Then you put the number of selections you want (33) as the numerator to 84, to get 33/84. Finally you simplify and get the probability of selecting a customer at random. Answer= 11/28 is your probability

What is the relative frequency for females in the age group 60-69?
a. 3/20
b. 1/5
c. 9/40
d. 2/5
Answer:
b) 8/40 = 1/5
The probability of the relative frequency for females in the age group 60-69 is 0.625.
We know that the probability of a function is the ratio of favorable cases to the total number of cases possible.
here we have to find the probability that a resident is female.
What is the formula for probability?[tex]Probability=\frac{Total \ numbers \ of \females}{Total \ number \of people}[/tex]
here the total number of females are=19+2+4
=25
and the total number of males=1+9+5
=15
Hence, the total number of people=25+15=40
So Probability=25/40
=0.625

A 29% B 31% C 33% D 35%
Answer:
A - 29%
Step-by-step explanation:
Bianca's 1/5 would be converted to 20%
Chelsea's .26 would be 26%
Darnell's is 25%
Adding these together you get 71. To find the remaining votes that Francisco received you would..
Subtract
100 - 71 = 29%
Therefor, your answer is A.
If Darell earned 25% of the vote and Francisco received the remaining votes, Chelsea would have garnered 0.26 percent of the vote. 29% of the votes were cast in favor of Francisco. Option A is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Given that there were four candidates running for office in the school election, Bianca won 1/5 of the vote, Chelsea got 0.26, Darell got 25%, and Francisco got the remaining votes.
Bianca's 1/5 would be converted to 20% and Chelsea's .26 would be 26%, Darnell's is 25%
Adding these together you get 71. To find the remaining votes that Francisco received you would be applying the subtraction operations,
100 - 71 = 29%

Find the area of the shaded region:
Find the area of the circle:
Area = PI x r^2
Area = 3.14 x 9^2
Area = 3.14 x 81
Area = 254.34 square cm
Now multiply the area of the circle by the shaded portion which is the fraction of the degree over 360 degrees:
254.34 x 80/360 = 20,347.2/360 = 56.52
The shaded area is 56.52 square cm.
Area of circle formula: A = πr²
A = π(9)²
A = 81π
A = 254.34cm²
The ratio of degrees in the shaded region to total degrees in a circle:
80/360 = 40/180 = 20/90 = 10/45 = 2/9
Multiply:
254.34/1 * 2/9
508.68/9
56.52
Therefore, the area of the shaded region is 56.52cm²

Mrs. Harless surveyed 18 students about the number of movies they watched this past summer. She displayed the results in a circle graph and a line graph. Which is the better display? Why?
The line graph is bettee.
The better display for the survey of 18 students about the number of movies they watched this past summer is a circle graph.
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given that, Mrs. Harless surveyed 18 students about the number of movies they watched this past summer, she used a circle graph and a line graph.
Since, a line graph used to track changes over short and long periods of time, It represents the change in a quantity with respect to another quantity. It shows how the value of something changes over time, or compare how several things change.
Whereas, a circle graph helps organize and show data as a percentage of a whole, it is divided into slices to illustrate numerical proportion.
Therefore, if Mrs Harless used a circle graph, it would be better to understand the data of the students.
Hence, the better display for the survey of 18 students about the number of movies they watched this past summer is a circle graph.

The function f(x) = 7x + 1 is transformed to function g through a horizontal compression by a factor of 1/3.What is the equation of function g?
Substitute a numerical value for k into the function equation.
g(x) = (7) kx
The correct question is;
The function f(x) = (7^x) + 1 is transformed to function g through a horizontal compression by a factor of 1/3.What is the equation of function g?
Substitute a numerical value for k into the function equation.
g(x) = 7^(kx)
Answer:
Value of k = 1/3 if the function is compressed by compression factor of 1/3.
Step-by-step explanation:
In transformations, the horizontal stretch or compression for a function f(x) is given by g = f(bx) where:
b is a constant.
If b > 0, then the graph of function is compressed.
Now, from the question, we are told that the function is transformed by a compression factor of 1/3.
Function is;f(x) = (7^x) + 1
In transforming to g = f(bx), we have;
g = (7^(x/3)) + 1
Since, we want to find k from the format g = 7^(kx)
Comparing with g = (7^(x/3)) + 1, we cans see that ; k = 1/3
The function g(x) is, [tex]g(x)=7(\frac{1}{3}x )+1[/tex]
The value of k is [tex]\frac{1}{3}[/tex]
To understand more, check below explanation.
Compression of function:The given function is,
[tex]f(x)=7x+1[/tex]
We have to find function g(x) from f(x) after compression by a factor of 1/3.
To find g(x), replace x by [tex]\frac{1}{3}x[/tex].
[tex]g(x)=7(\frac{1}{3}x )+1\\\\g(x)=\frac{7}{3}x+1[/tex]

in a survey of 80 people.it was found that 60 liked oranges only and 10 liked both oranges and apples.the number of people who liked oranges is five times the number of people who liked apples. by using venn-diagram, find the number of people who liked apples only and who didn't like any of these fruits
There are 4 people who only like apples, and 6 people who do not like any fruit.
Since in a survey of 80 people it was found that 60 liked oranges only and 10 liked both oranges and apples, and the number of people who liked oranges is five times the number of people who liked apples, to determine the number of people who liked apples only and the number of people who didn't like any of these fruits, the following calculations must be performed:
First, the number of people who like apples must be determined, knowing that it is 5 times less than the number of people who like oranges.
(60 + 10) / 5 = X 70/5 = X 14 = X
Thus, 14 people like apples, of which 10 of them also like oranges. So there are 4 people who only prefer apples, added to 60 people who prefer oranges and 10 who like both fruits. This gives a total of 74 people, which implies that 6 people do not like any fruit.
