A group of seventh graders and a group of teachers at a local middle school were 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 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. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answers
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.

Josh rents a kayak at a nearby state park. He pays a one-time rental fee of $12.50 plus an additional $3.75 for each hour he spends in the water. How much did Josh spend if he was on the river for 4 1/3 hours a day?
Answers
Answer:
$28.75
Step-by-step explanation:
$12.50 + ($3.75 x 4) = ?
3 3/4 x 4 1/3
15/4 x 13/3 --> 5/4 x 13/1 = 65/4
65/4 can be simplified to $16.25
$12.50 + $16.25 = $28.75

there must be at least 2 boxes of fudge containing nuts at the fudge shop on Monday morning.The scenario states that the total amount of fudge containing nuts on Monday afternoon is at least 29(5/8) pounds. So, we can write the inequality:x + 12(3/4) ≥ 29(5/8)
How to solve the question?
(a) Let's define "x" as the amount of fudge containing nuts that was at the fudge shop on Monday morning. Since three-fourths of the fudge contains nuts, we can say that:
x = (3/4)total fudge at the fudge shop on Monday morning
Then, Helena prepares an additional 12(3/4) pounds of fudge containing nuts. Therefore, the total amount of fudge containing nuts on Monday afternoon is:
x + 12(3/4)
The scenario states that the total amount of fudge containing nuts on Monday afternoon is at least 29(5/8) pounds. So, we can write the inequality:
x + 12(3/4) ≥ 29(5/8)
(b) Let's first convert the mixed number 12(3/4) into an improper fraction:
12(3/4) = (4*12 + 3)/4 = 51/4
Similarly, we can convert the mixed number 29(5/8) into an improper fraction:
29(5/8) = (8*29 + 5)/8 = 233/8
Now, we can substitute these values into the inequality we wrote in part (a):
x + 51/4 ≥ 233/8
To solve for x, we need to isolate it on one side of the inequality. Let's start by subtracting 51/4 from both sides:
x ≥ 233/8 - 51/4
x ≥ 10/8
Simplifying the right-hand side:
x ≥ 5/4
Therefore, the inequality that represents the scenario is:
(3/4)total fudge at the fudge shop on Monday morning + 12(3/4) ≥ 29(5/8)
And the solution to this inequality is:
x ≥ 5/4
(c) Since fudge is packaged into 1-pound boxes, the fewest number of boxes of fudge at the fudge shop on Monday morning is equal to the amount of fudge containing nuts on Monday morning, which is "x". From part (b), we know that:
x ≥ 5/4
The smallest whole number that is greater than or equal to 5/4 is 2. Therefore, there must be at least 2 boxes of fudge containing nuts at the fudge shop on Monday morning.

Step-by-step explanation:
First you have to turn 2/3 into ninths which would be 6/9. Then you have to turn 1/9 into 10/9 by giving one whole and turning it into a fraction. Then you have to subtract 10/9 - 6/9 = 3/9. Finally you have to subtract the wholes 10-3= 7 then your answer would be 7 3/9
Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.
