Least to Most Likely:

In this order:

Honor (1/10=10%)

Simple (30%)

Bonus (3/5=60%)

Answer: honor tile, then simple tile, then bonus tile.

Explanation:

Let's get all the probabilities to become a fraction with a denominator of 10 so it will be easier to compare

simple tile - 30% equals 0.3=3/10

honor tile - 1/10 is already good

bonus tile - 3/5=6/10

1/10 is the least likely, followed by 3/10, and 6/10 is the most likely

honor tile, then simple tile, then bonus tile.

A survey of a group of seventh-graders and a group of teachers at a local middle school asked how many siblings they each have. The dot plots below show the results.

Students
A dot plot titled Students. A number line going from 0 to 9 labeled the number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9.

Teachers
A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9.

Based on the shape of the two-dot plots, which statements correctly compare them? Select three choices.
The center of the data for students has a value less than that of the center of the data for teachers.
The center of the data is to the right of the dot plot for both teachers and students.
There is a greater variation in the data for teachers than for students.
Both sets of data cluster around 2.

JJ’s Fitness Club offers two different fees for their yoga classes. Club members are charged a one-time membership fee of $24 and pay $3 per class. Non-members pay $7 per class. How many classes result in the same cost for a member and non-member?

Answers

Answer:

So the answer is 13 classes member and 9 non member

Step-by-step explanation:

so you gotta do 24 + 3x = 7y ok?

and x equals 13 so 39 + 24 = 63

and non member is 7x = 63

x = 9

Hope I helped :D

the answer is 5x. Step One: Where x equals the number of aerobics classes,
Members Nonmembers
Cost in Dollars 10+3x 0+5x
Step Two: We create an equation to solve for x.
Member Cost=Nonmember Cost
10+3x= 0+5x
Step Three: Solve for x:
10+3x= 5x Subtract 3 from both sides
10=5x-3x Combine like terms
10=2x
5=x

HELP MEEE PLEASE ILL MARK BRIANLIST!!!!

Answers

The points in order from top to bottom are :

F
E
C
H
I
a) -x= F
the start of the question gives x=-2 which then you flip the signs to get -x=2. The point that corresponds with 2 is F
b) |-1.5|= E
When a negative number is put in absolute values it becomes positive so in this case we would be looking for the point which had a value of 1.5 which is point E
c) -4= C
-4 is corresponding to C
d) |5|= H
As 5 is already positive the absolute values don’t matter. H corresponds with the number 5
e) |-6|=I
Similar to (b) the number is negative so the absolute values would make it positive and positive 6 is located at I
