Noah gathered information on the home states of the swimmers on Team USA. He organized the data in a table. Would a dot plot be appropriate to display his data? Explain your reasoning.This dot plot shows the ages of students in a swimming class. How many students are in the class?
Based on the dot plot, do you agree with each of the following statements? Explain your reasoning.
The class is an adult swimming class.
Half of the students are between 2 and 3 years old.
Answer:
1. No; 2. 16; 3. No; 4. Yes
Step-by-step explanation:
1. Home states of Olympic swimmers
A dot plot compares frequency counts within groups, usually with small sets of data.
Thus, it is great for visualizing quantitative data.
Home states are qualitative data.
It might be better to use a packed bubble chart, especially if more than 20 to 30 states are on the team.
In such a chart, the frequency with which the state name is mentioned would determine the relative bubble size.
It might look like the imaginary chart shown below.
A dot plot would not be appropriate.
2. Number of students
No. of students = 2 + 1 + 2 + 3 + 2 +1 + 1 + 2 + 2 = 16
3. Is this an adult swimming class?
The ages of the students range from 18 mo to 32 mo.
This is not an adult swimming class.
4. Ages of half the students
Half of 16 students is eight students.
The eight oldest students range in age from 25 mo to 32 mo.
This is between the ages of 2 yr to 3 yr (24 mo to 36 mo), so
Half the students are between 2 yr and 3 yr old.

The graph below shows the distance in miles, m, hiked from a camp in h hours.
Which hourly interval had the greatest rate of change?
1) hour 0 to hour 1
3) hour 2 to hour 3
2) hour 1 to hour 2
4) hour 3 to hour 4
Answer:
Option 1) is correct
Step-by-step explanation:
Given: The graph shows the distance in miles, m, hiked from a camp in h hours.
To find: hourly interval that had the greatest rate of change
Solution:
Rate of change between two points refers to the vertical change divided by the horizontal change.
For hour 0 to hour 1:
rate of change = [tex]\frac{2-0}{1-0}=2[/tex]
For hour 2 to hour 3:
rate of change = [tex]\frac{4.5-3.5}{3-2}=1[/tex]
For hour 1 to hour 2:
rate of change = [tex]\frac{3.5-2}{2-1}=1.5[/tex]
For hour 3 to hour 4:
rate of change = [tex]\frac{5-4.5}{4-3}=0.5[/tex]
So, rate of change is greatest in interval: hour 0 to hour 1
The greatest rate of change between the interval 0 to 1 hour.
Given that,
The graph below shows the distance in miles, m, hiked from a camp in h hours.
We have to determine,
Which hourly interval had the greatest rate of change?
According to the question,
The greatest rate of change between the interval is determined by the rate of change between two points refers to the vertical change divided by the horizontal change.
1. The rate of change between 0 to 1 hours is,
[tex]\rm Rate \ of \ change = \dfrac{2-0}{1-0}\\\\ Rate \ of \ change= \dfrac{2}{1}\\\\ Rate \ of \ change= 2[/tex]
The rate of change between 0 to 1 hour is 2.
2. The rate of change between 2 to 3 hours is,
[tex]\rm Rate \ of \ change = \dfrac{4.5-3.5}{3-2}\\\\ Rate \ of \ change= \dfrac{1}{1}\\\\ Rate \ of \ change= 1[/tex]
The rate of change between 2 to 3 hours is 1.
3. The rate of change between 1 to 2 hours is,
[tex]\rm Rate \ of \ change = \dfrac{3.5-2}{2-1}\\\\ Rate \ of \ change= \dfrac{1.5}{1}\\\\ Rate \ of \ change= 1.5[/tex]
The rate of change between 1 to 2 hours is 1.5.
4. The rate of change between 3 to 4 hours is,
[tex]\rm Rate \ of \ change = \dfrac{5-4.5}{4-3}\\\\ Rate \ of \ change= \dfrac{0.5}{1}\\\\ Rate \ of \ change= 0.5[/tex]
The rate of change between 2 to 3 hours is 1.
Hence, The required greatest rate of change between the interval 0 to 1 hour.

A car rental company charges x dollars to rent a truck, plus y dollars per kilometre. Find x and y if the rental charge is $90 for 100 km, and $110 for 150 km.
Answer:
X=50 dollars Y=0.4 dollars
Step-by-step explanation:
Starting with the two equations:
$90= X(truck cost)+ Y(cost per km)*100km
and
110=X+Y*150
we solve the first equation for X: X = 90-100Y
and plug X into the second equation: 110=90-100Y+150Y
add like terms: 20=50Y
so Y = 2/5 or .4
Plug Y into the first equation: 90= X+100(.4)
Evaluate: 90= 40+X so X= 50
Answer:
X = 50 dollars
and Y= o.4 cents

Answer: B (15 to 42)
Step-by-step explanation:
In order to get from 14 to 42, you must multiply by 3 (42/14 = 3). So to get an equivalent ratio, you must also multiply 5 by 3.

Twenty-two percent of the large pieces of mail that Rachel received this week were magazines and the rest were catalogs. Of the catalogs, 36 percent were for clothing. To the nearest whole percent, what is the probability that a randomly chosen large piece of Rachel’s mail was a clothing catalog? 8% 28% 46% 61%
Answer:
28%
Step-by-step explanation:
Given that
The calculation of probability that a randomly chosen large piece of Rachel’s mail was a clothing catalog is shown below:-
Remaining of large pieces of mail were catalogs
= 100% - 22%
= 78%
Now, we will solve the equation to find out the probability that a randomly chosen large piece of Rachel’s mail was a clothing catalog
[tex]= \frac{36}{100}\times \frac{78}{100}\times 100[/tex]
[tex]= \frac{2,808}{10,000}\times 100[/tex]

Answer:
9(3+4)
Step-by-step explanation:
27+36
Factor out 9
9*3 + 9*4
9(3+4)
Answer:
9(3+4)
Step-by-step explanation:
First, list all the factors of the two numbers. Factors are numbers that evenly divide into a number.
Factors of 27: 1, 3, 9, 27
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36
Now, find the GCF. The GCF is the largest factor both numbers share. In this case, the GCF is 9.
Now, find the equivalent expression.
27+36
Distribute out a 9. Divide both numbers inside the parentheses by 9.
9(27/9+36/9)
9(3+4)

Maria has a jewelry box and wants to increase its size. She decides she will double the length, width and height. How many times
bigger will the volume of the new box be?
2
3
5
8
Answer:
64 times bigger
Step-by-step explanation:
I will use random values for this explanation to make it more understandable.
Lets say the length of the box is 1 inch, width is 1 inch, and height is 1 inch.
The volume would be l*w*h = 1*1*1 = 1 cubic inch
If the dimensions were 4 times bigger, the length, width and height would all be 4 inches.
4*4*4 = 64 cubic inches, which is 64 times bigger than the smaller box with a volume of 1 cubic inch.

The points (-11, r) and (-7,5) lie on a line with slope

4
Find the missing coordinate r.
Answer:
r = 2
Step-by-step explanation:
Calculate slope m using the slope formula and equate to [tex]\frac{3}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 11, r) and (x₂, y₂ ) = (- 7, 5)
m = [tex]\frac{5-r}{-7+11}[/tex] = [tex]\frac{5-r}{4}[/tex] = [tex]\frac{3}{4}[/tex] ( multiply both sides by 4 to clear the fractions )
5 - r = 3 ( subtract 5 from both sides )
- r = - 2 ( multiply both sides by - 1 )
r = 2
