A group of students was asked about the number of e-mails they each sent
that day. The results are:
0,0,0,0,1,2,2,3,5,5, 8, 9, 10, 10, 10
Which histogram correctly shows the data set?

Answer:

EG = 84

Step-by-step explanation:

Here, we want to get the length of EG

Mathematically, we will be considering two triangles

these are EFJ and EHG

These two triangles are similar as can be seen

when two triangles are similar, the ratio of their corresponding sides are equal

Thus, we have it that;

EH/EG = EJ/EF

let us represent EF by x

so; EG is (x + 72)

EH = 3 + 18 = 21

Hence, we have it that;

21/x+ 72 = 3/x

21(x) = 3(x + 72)

21x = 3x + 216

21x-3x = 216

18x = 216

x = 216/18

x = 12

EG = 12 + 72 from EG = x + 72

EG = 84

Answer:

the answer is d=20.5 hope this helped

Answer:

d= 20.5

Step-by-step explanation:

d/4+7/8=6

(we know that to add fractions, we have to have both denomiators the same number. We aslo know that that means 8. Using that information, we know that to top number must be 48. 48/8 = 6. We can substract)

48-7= 41

(we then need to divide by 2 as we would have had to already multiplyed 4 by 2.)

41/2 = 20.5

Answer: 1.2 blocks

Step-by-step explanation:

Timothy walks 12 blocks in 10 minutes so it can be written as

12 blocks = 10 minutes

divide both sides by 10

1.2 blocks per minute

10 and -6

Answer:

18 is 3 more than 9- false

18 is 3 times as much as 6 - true

9 is 3 times as much as 27- false

9 is 3 more than 6 - true

Answer:

£2308.5 per day

Step-by-step explanation:

Since in one day they have to deliver 384 catalogues and 1890 leaflets and each student can deliver either 16 catalogues or 90 leaflets in hour, the amount of students required to deliver 384 catalogues in one hour is 384/16 =  24 students.

Also, the number of students required to deliver 1890 leaflets in one hour is 1890/90 = 21 students.

So the total number of students required to make the delivery is thus 24 + 21 = 45 students. This is the minimum number of students required for the delivery.

Since all students hired are paid £51.30 per day, even if they don't work a full day, so the amount of wage paid for this minimum amount of students is thus minimum amount × wage = 45 × £51.30 per day = £2308.5 per day

Answer:

£307.80

Step-by-step explanation:

Wow seems the verified answer is wrong.

Who would've thought?

16*384=24

90*1890=21

21+24=45

45/8=5.62500

5.625 rounds to 6

51.30*6=£307.80

Thats your working out

You have to divide 45 by 8 because there are 8 hours in a day in which they can work.

Then round the number as you cant have a fraction of a person

Which you would then multiply by 51.30

Brainliest would be appreciated <33

Answer:

85

Step-by-step explanation:

425 divided by 8= 85

Answer:

He as 85 race cars.

Step-by-step explanation:

Just divide 425 by 5 and you have your answer.

2x^2 = 72

Divide both sides by 2:

X^2 = 36

Take the square root of both sides

X = 6

Answer:

12

Step-by-step explanation:

Through 12 years  he would have painted 72 paintings and since he hasn't sold two of them he has only sold 70.

Answer:

3,992

Step-by-step explanation:

1/10 = 0.1

399.2/0.1 = 3,992

Answer:

3990

Step-by-step explanation:

Place the decimal to a fraction:

399.2 = 399 2/10

Simplify =  399 1/5

Put in improper fraction = 1995/5

Simplify more = 399/1 or 399

So:

399 divided by 1/10 = 3990

Answer:

click c

Step-by-step explanation:

and its right

21 is the right answer.

180-138=42°

and since it is given in the question that the triangle is isoceles ,so half of 42 is 21°

Step-by-step explanation:

Answer:

D. The length is the same as line MN.

Step-by-step explanation:

Even if the line is moved any one bit, the length of the line will not change. So as a result, A, B & C are already out. That leaves D as our answer.

Answer:

[tex]\{x: 0 \le x \le 40 \}[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

The domain of the graph

To do this, we simply write out the range of value of the x-coordinate.

From the attached graph, the x values are:

[tex]x = [0,40][/tex] i.e. from 0 to 40 (both inclusive)

So, the domain is:

[tex]\{x: 0 \le x \le 40 \}[/tex]

Answer:

x = -5

Step-by-step explanation:

Please write this as y = x^2 + 10x + 25.  Here the coefficients are {1, 10, 25}.

The equation of the axis of symmetry is x = -b/[2a], which here is

x = -10 / [2*1] = -5

Answer:

6 in. per triangle & 24 in total (white squares only)

Step-by-step explanation:

 So, one side is 12 inches and each side is made up of one blue and one white. With this you can just divide each side by 2, getting 6. There are 4 sides so,

4 sides X 6 in. per each square= 24

Therefore, she used 24 in. in total and 6 for each triangle.

Answer:

FV= 11.369 gr

Step-by-step explanation:

Giving the following information:

Growth rate (g)= 25% per day

Number of periods (n)= 14 days

Present Value (PV)= 0.5 gr

To calculate the Future Value(FV) in grams, we need to use the following formula:

FV= PV*(1+i)^n

FV= 0.5*(1.25^14)

FV= 11.369 gr
