210 students were asked whether they want to go to a water park or a roller skating rink for a class party. 50 students are girls who want to go to the water park. 45 students are girls who want to go skating. 60 students are boys who want to go to the water park. Answer the questions to analyze the data. 1. Use the given information to fill in the two-way table. ‘a Water park Skating Total Boys 60 55 115 Girls 50 45 95 Total 110 100 210 2. How many boys want to go skating? 55 3. To the nearest hundredth, what is the relative frequency of boys who want to go to the water park? 4. The probability that a student is in a category can be approximated by the relative frequency. To the nearest hundredth, what is the probability that a randomly selected student is a girl who wants to go skating? Show how you know. 5. Are there more boy students or girl students? Do you read this information from the joint frequencies or the marginal frequencies? Explain how you know. 6. Which destination is more popular, the skating rink or the water park? Explain how you know.

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.

Answer:

maybe 3.6?? i dont exactly know what the absolute deviation for 3 is but i have the standard deviation

Step-by-step explanation:

sorry

Answer:

Maybe 3/4

Step-by-step explanation:

3/4 because when you use the gridlines, whenever the line passes each x value, the line goes 75% down each x value. (i dont know how to explain)

Answer: irregular

it is irregular because its sides are not equal

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

Answer:

hi

Step-by-step explanation:

A is 50 and B is 10

then, C is 5

50+10=60

50-10=40

50÷10=5

have a nice day

Answer:

Step-by-step explanation:

A+B=60

A=60-B

substitute the value of A in

A-B=40

60-B-B=40

60-40=2B

20/2=B

10=B

Now, substitute the value of B in

A+B=60

A+10=60

A=60-10

A=50

A/B=C

50/10=C

5=C

Answer:

1. 30 metres

2. 27 squared feet,

3.  25.13 cm

4. 50.27 sqared inches

5. 15.71 metres

6. 380.13 squared metres

7. Area is: 4.52 squared metres Circumference is: 7.54 metres

8. Circumference is: 47.12 feet Area is: 176.71 squared feet

Step-by-step explanation:

1. Since you're rounding pi, your calculation would be:

2 × 3 × 5 = 30

---------------------------------------------------------------------------------------------------------------

2. Since you're rounding pi, it would be:

3 × 3² = 27

---------------------------------------------------------------------------------------------------------------

3. Use the formula for number 5

---------------------------------------------------------------------------------------------------------------

4. Use the formula in number 6

---------------------------------------------------------------------------------------------------------------

5. Formula for the circumference of a circle is:

[tex]C=2\pi r[/tex]

So:

2 × 3.14 × 2.5 = 15.71

---------------------------------------------------------------------------------------------------------------

6.  Formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

So:

3.14 × 121 =  380.13

---------------------------------------------------------------------------------------------------------------

7. Use the formula for numbers 5 and 6 to figure these out

---------------------------------------------------------------------------------------------------------------

8. Use the formula for 5 and 6, except divide the diameter by 2 because the formula only works with the radius

---------------------------------------------------------------------------------------------------------------

Have a good day :)

Answer:

1. 31.4m

2. 26ft

3. 25.12 cm

4. 50.24 in

5. 15.71 meters

6. 380.13 inches

7. 7.5meters

8. 47.1 feet

Step-by-step explanation:

to find the circumference you do 2 x 3.14 x radius

to find the area you do radius squared x 3.14

Answer:

d = -10/7 = -1 3/7

that is the answer for number 1.

For number 2. the answer is U = 13/4 = 3 1/4 = 3.25

step by step explanation

multiply both sides of the equation by 4 the least common multiple of 2,4

2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10

2 (10 + 1) -4u =9

then add 10 and one to get 11

2 x 11 -4u =9

then multiply two and 11 to get 22

22 -4u = 9

then subtract 22 from both sides

subtract 22 - 9 to get -13

-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4

your answer is 13/4

When comparing bars side by side, they should have a consistent scale.

Use a side by side bar or a clustered bar graph to enable comparisons of individual values.

Use a stacked bar graph to highlight part to whole relationship.

Use a logarithmic scale if your audience can understand it.
