The middle value of the ordered data set is 7.
The value that occurs most often in the set is 7.
The difference between the smallest value and the largest value is 7.
The sum of all the data values divided by the number of data values is 7.
Answer:
4. The sum of all the data values divided by the number of data values is 7.
In short, the mean of the data is the average.

The red line is the entire angle which is shown as 66.8 degrees.
One of the two angles is shown as 40.8 and the other one is x.
To find x subtract 40.8 from 66.8
X = 66.8-40.8 = 26
X = 26 degrees.

Janet can make 1/2 of a necklace in 20 minutes. At this rate, how many necklaces can Janet make in 2 hours?
Answer:
3 necklaces
Step-by-step explanation:
2 hours = 120 minutes
1 necklace in 40 minutes
120/40 = 3
3 necklaces
Answer:
3 necklaces
Step-by-step explanation:
2 hours needs to be in the same units as the 20 minutes
2 hours = 2 * 60 minute = 120 minutes
Now we can use ratios to solve
1/2 necklace x necklaces
-------------------- = ----------------
20 minutes 120 minutes
Using cross products
1/2 * 120 = 20x
60 = 20x
Divide by 20
60/20 = 20x/20
3= x

With step by step explanation = Brainliest
Answer:
don't know
Step-by-step explanation:
ok please mark mr brainlist
Answer:
3%
Step-by-step explanation:
Interest rat is calculated by using the equation A = P(1 + r)^n
A is the amount after interest. Here, it is 1635.30
P is the principal, or base, amount. Here, it is 1422
r is the rate at which there is interest. It is what we need to find out.
n is the amount of years interest is calculated for. Here, it is 5
Now that we have everything, we calculate:
1635.30 = 1422(1 + r)^5
Now we have to get r on one side of the equation by itself:
Divide both sides by 1422:
1635.30/1422 = (1 + r)^5
5√(1655.30/1422) = 1 + r
5√(1.16406469) - 1 = r
Now r is on one side of the equation.
The 5th root of 1.16406469 is 1.03084987
1.03084987 - 1 = 0.0308, so it is 3%
The 5√ is the 5th root of the numbers
Or it's 2.835 percent I don't know

What is the probability of landing on A then a C?* First Spin Second Spir С C E A B A DC
Answer:
Probability of landing on A: 25% chance
Probability of landing on C: 37.5% chance
Step-by-step explanation:
A. There are 2 A’s out of 8 letters which gives us a fraction of 2/8.
2/8 = 1/4 = 0.25 = 25%
C. There are 3 C’s out of 8 letters which gives us a fraction of 3/8.
3/8 = 0.375 = 37.5%
Hopefully this helped, good luck!
pls help me find the volume of the triangular prism
Let's find the area of the triangle first:
2 x 5 = 10, 10 divided by 2( x 1/2 ) = 5
5 x 4(width) = 20
Formula of area of a Triangle:
BH x 1/2
(base) x (height) x 1/2(basically just dividing by 2)
Can someone help me with this question
anyone knows the answer ???
Answer:
C
Step-by-step explanation:
The answer is C because both of the equations have less than or equal to symbols. So, you would shade below both lines. The only place where the two lines mix shades is C.
The legs of a right triangle are 15 feet and 18 feet long. What is the area of the triangle?
Answer:
135
Step-by-step explanation:
Well, this is easy!
We just have to remember the formula!
L*W*1/2
We get 270/2.
This equals 135!

Which algebraic representation best represents the translation?
А.
A) x-3, y +4
B) x - 4, y + 3
C) x + 4, Y-3
D) x + 3, y - 4
Answer:
C
Step-by-step explanation:
The x-axis got added 4 units.
The y-axis got subtracted 3 units.
And that is what it says on answer C.
add 223+374+402 using expanded form
next,change your answer back too standard form

Choose the graph that represents the following system of inequalities:
y ≥ −3x + 1
y ≥ 1 over 2x + 3
In each graph, the area for f(x) is shaded and labeled A, the area for g(x) is shaded and labeled B, and the area where they have shading in common is labeled AB.
Graph of two intersecting lines. Both lines are solid. One line f of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line g of x passes through points 0, 1 and 1, negative 2 and is shaded above the line.

Answer:
FIRST.
64 square inches matches to a cross section parallel to the base of a right rectangle prism that is 3 inches long, 7 inches wide, and 11 inches tall
This is shown in the first figure below. A right rectangular prism where every edge connecting its base and the opposite face makes right angles with both faces. Since the tall is the side that measures 11 inches, then the base is formed by 3 inches long and 7 inches wide. Therefore, the area of this shape can be found as the area of a rectangle, which is: 21 in squared.
SECOND.
64 square inches matches to a cross section parallel to the base of a cube whose edges are 8 inches long.
This is shown in the second figure below. A cube is a prism whose sides all have the same length and in this case is 8 inches. We name cross section is to the slice that cuts through a solid. If the cross section is parallel to the base of a cube, then it forms a square with length . Therefore, the area of this shape can be found as the area of a square, which is: 64 in squared.
Third.
7 square inches matches to a cross section passing through the diagonal of opposite faces of a cube with edges that are 7 inches long and a diagonal that is approximately 10 inches
This is shown in the third figure below. As you can see, the cross section passes through the diagonals of the base and the top of the cube that are two opposite faces. This form a rectangle having sides where:
So: 70 in squared
FOURTH.
300 square inches matches to a cross section perpendicular to the base and passing through the diagonals of the base and opposite face of a right rectangular prism that is 24 inches wide, 7 inches long, and 12 inches tall and measures 25 inches along the diagonal of the base.
This is shown in the fourth figure below. The cross section passes through the diagonals of the base and the top of the right rectangular prism. They are opposite to each other, so the shape of the cross section is a rectangle whose sides are where:
So: 300 in squared.
