Sonya infers that, on average, most seventh graders use the Internet a little more than 7 hours each week. Based on the dot plot, which number is the median of Sonya's data?
Answer:
I Think that it is 7.5

Hope that his helps you :-)
The median and mean of the data is 7.5
What is Arithmetic Mean?The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.
Given:
According to box plot the mean is
= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26
= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26
= 195 / 26
= 7.5
Hence, the mean is 7.5.
Also, the median = (7+8)/2 = 7.5

Create an equation modeling the scenario. Use the equation to solve for the missing number. In your final answer, include the equation and all necessary calculations. Twice the sum of a number and seven is three times the number.
Answer:
2(n+7)=3n
Step-by-step explanation:
"A number" is unknown so just create a variable in this case I made it "n."
We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.

Maria has a new fish tank for her goldfish. The tank measures 912 inches long, 312 inches wide, and 612 inches tall.
Part A:
What formula should Maria use if she wants to know the volume of her new fish tank?
Part B:
Using the formula you wrote for Part A, what is the volume of Maria's new fish tank?
I'm giving out Brainliest!
Step-by-step explanation:
step 1. V = LWH. L = length. W = width. H = height.
step 2. V = (912)(312)(612) = 174,140,928 in^3.
The volume of Maria's new fish tank is 174,140,928 cubic inch.
It is required to find the volume of Maria's new fish tank.
What is cuboid?In geometry, a cuboid is a solid shape or a three-dimensional shape. A convex polyhedron that is bounded by six rectangular faces with eight vertices and twelve edges is called a cuboid.
Given :
Maria has a new fish tank for her goldfish.
The fish tank is in the shape of cuboid.
length=912 inches
width=312 inches
Height=612 inches
Part A
The formula of volume of her new fish tank
Volume=length ×width × height.
Part B
Volume=length ×width × height.
By the use of formula we have,
V = (912) ×(312) ×(612)
V= 174,140,928 cubic inch.
Therefore, the volume of Maria's new fish tank is 174,140,928 cubic inch.

Function 2:
Graph of a line passing through the point begin ordered pair negative 2 comma 0 end ordered pair and the point begin ordered pair 0 comma 4 end ordered pair.
Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
Step-by-step explanation:
Given that function 1 has the table;
x y
0 -2
2 0
3 1
5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
