Answers
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4

How do u find the area of this figure
Answers
Answer:
The answer is 52 in²
Step-by-step explanation:
You can't find the area of it all at once so you must cut it in have to have two shapes like in the picture above and then name them A and B
Now for the shapes we must use the formula Area= Lentgh times Breath
Shape A: A= L x B
8 x 6 = 48 in²
Shape B : A= L x B
2 x 2= 4 in²
now add 48 plus 4 = 52 in²

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Step-by-step explanation:
A ratio refers to a fraction. In this case the question asks how many players to coaches there are.
The word "to" means that is where the fraction bar goes.
Players/Coaches
There are 18 players and 3 coaches.

18 can be divided by 3, 6 times so the fraction can be simplified to
6/1 meaning there are 6 players for every coach.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Mean, Median, Mode, Range
Objective: Identify the mean, median, mode, and range in application problems
Directions: Watch the following video. Then read the lesson and take notes before completing the lesson review.
Introduction
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list. Mean, median, and mode are measures of central tendency and are three different ways of expressing averages of a set of data.
Mean: The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set. The mean is also called the average.
Example:
Data Set = 2, 5, 9, 3, 5, 4, 7
Number of Elements in Data Set = 7
Mean = ( 2 + 5 + 9 + 7 + 5 + 4 + 3 ) / 7 = 5
Median: The "Median" of a data set is dependent on whether the number of elements in the data set is odd or even. First, reorder the data set from the smallest to the largest then if the number of elements is odd, then the Median is the element in the middle of the data set. If the number of elements is even, then the Median is the average of the two middle terms.
Example: Odd Number of Elements
Data Set = 2,5,9,3,5,4,7
Reordered = 2,3,4,5,5,7,9
Median = 5
Example: Even Number of Elements
Data Set = 2,5,9,3,4
Reordered = 2,3,4,5,9
Median = (4+5)/2 = 4/5
Mode: The "Mode" for a data set is the element that occurs the most often. It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set. A data set with two modes is called bimodal. A data set with three modes is called trimodal.
Example: Single Mode
Data Set = 2,5,9,3,5,4,7
Mode = 5
Example: Bimodal
Data Set = 2,5,2,3,5,4,7
Modes = 2 and 5
Example: Trimodal
Data Set = 2, 5, 2, 7, 5, 4, 7
Modes = 2, 5, and 7
Range: The "Range" for a data set is the difference between the largest value and smallest value contained in the data set. First, reorder the data set from smallest to largest then subtract the first element from the last element.
Example:
Data Set = 2, 5, 9, 3, 5, 4, 7
Reordered = 2, 3, 4, 5, 5, 7, 9
Range = (9-2) = 7

A jar contains 5 blue marbles, 8 red marbles, 4 white marbles, and 3 purple marbles. Suppose you pick a marble at random without looking. Find the probability of the event.
Answers
Answer: A 1/5
Step-by-step explanation:
Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.
What is probability ?
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Number of blue marbles = 5,
Number of red marbles = 8,
Number of white marbles = 4,
And number of purple marbles = 3.
Total number of marbles = 5 + 8 + 4 + 3 = 20
Probability of getting blue marble = number of blue marbles/total number of marbles
=5/20=1/4
Apply same formula,
Probability of getting red marble= 8/20 = 2/5
Probability of getting white marble = 4/20 = 1/5
Probability of getting purple marble = 3/20
Answer:
A 1/5

Next, we calculate the fraction of a picture painted per hour:
Fraction painted per hour = (3)/(4) / (5)/(2) = (3)/(4) * (2)/(5) = (6)/(20) = (3)/(10)
Now, we can calculate the number of pictures painted in 5 hours:
Pictures painted in 5 hours = (3)/(10) * 5 = (15)/(10) = 1.5
