Key: 3|1 means 3.1

What is the mean, and what does it tell you in terms of the problem?
A.3.1 feet; The value means the furthest the ball went.
B.3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.
C.4.1 feet; The value means this measurement had the most occurrences.
D.4.65 feet; The value means that a typical throw of the ball results in 4.65 feet.

Answers

Answer: B) 3.875

Step-by-step explanation:

To start off, finding the mean is the AVERAGE. To find the average, you must add all of the values, and divide by however many values there are (in this case, there are 12) So first add all of the values:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2+2.2+2.5+3.1+3.3+3.4+4.1+4.1+4.5+5+5.6+6.7 = 46.5 (or 46.50)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

next, you divide 46.5 by however many values there are (in this case, there are 12)

So, 46.5 / 12 is equal to 3.875

This tells us that the average distance of the throw is 3.875 feet

Therefore, the correct answer is B.3.875 feet; The value means that a typical throw of the ball results in 3.875 feet.

Answers

Answer: predator is a tiger

climate change is making the rabbit heat up

Step-by-step explanation:

Answer:

Step-by-step explanation:

Introducing a predator to the area would help to stabilize the rabbit population over time. As the predator hunts the rabbits, it would reduce the population, preventing it from growing too large and potentially causing overgrazing and resource depletion. This would lead to a more stable population over time. Climate change is unlikely to have a stabilizing effect on the population as it can have unpredictable and often negative impacts on ecosystems and their inhabitants.

Step-by-step explanation:

Answer:

41.7 square meters

Step-by-step explanation:

First, rectangle A:

4 x 6 = 24 square meters

Second, rectangle B:

We know the length of this section is 3.5m. For the height/width, we can look at rectangle C. The height of C is 3.8m, and we see the part of C that is NOT part of B is 2m long. So we subtract 2 from 3.8 to find the height of B.

3.8 - 2 = 1.8m

Then, for the area of B:

3.5 x 1.8 = 6.3 square meters

Third, rectangle C:

3 x 3.8 = 11.4 square meters

Add up areas of A, B, C:

24 + 6.3 + 11.4 = 41.7 square meters

A new roller coaster just opened at Friday Fun Park. When Lisa got in line, a sign said the wait from that point would be 45 minutes. The actual wait was only 35 minutes. What is the percent error for the park sign's estimate?
If necessary, round your answer to the nearest tenth of a percent.

Answers

Answer: 28.6%

Step-by-step explanation:

To calculate the percent error:

1) Subtract the estimated amount by the actual amount

45-35=10

2) Divide the answer by the actual amount

10/35=0.2857

3) Multiply the answer by 100 to get the percent error

0.2857×100=28.57

Rounded that equals 28.6%

Answer: hope this helps ♡

The percent error for the park sign's estimate is 29%.

Step-by-step explanation:

45 - 35 = 10

(10 out of 35 because it's the actual amount)

10 of 35 in percentage:

(10 ÷ 35) × 100 =

0.28571..... × 100 =

whats the surface area?

whats the surface area?

Answers

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

Base area

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

Lateral area

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

Total area

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500
