Answer:

C≈47.25

Step-by-step explanation:

Use the formula C= πd, where C is circumference, π is pi, and d is diameter.

Input the numbers and we'll shorten π to 3.15

C=3.15(15)

C≈47.25

Hi!

To find the circumference of a circle, use the following formula:

$\implies\sf{Circumference_o=\pi d}$

where d is the diameter.

Now, we know that the diameter is 15 ft, so let's plug that into the formula:

$\implies\sf{Circumference_o=15\pi }$

We've found the circumferencce in terms of pi! Cheers :)

Have a nice day!

I hope this helped.

The line plot below shows the heights of flowers in a garden. How much taller is the tallest flower than the shortest flower?

Marat540 [252]

Answer:

1 3/4 inches

Step-by-step explanation:

Given:

The line plot below shows the heights of flowers in a garden.

To Find:

How much taller is the tallest flower than the shortest flower?

Solve:

Knowing that each dot represent it's heights.

Let's makes a table:

6 1/2 ⇒ О О

6 3/4 ⇒ О

7 ⇒ ОООО

7 1/4 ⇒ ОООООО

7 1/2 ⇒ ОООО

7 3/4 ⇒ ОО

8 ⇒ none

8 1/4 ⇒ О

8 1/2 ⇒ none

It's also given that the tallest flower and the shortest flower.

Which is:

Smallest → 6 1/2

Tallest → 8 1/4

Now all we have to do is subtract tallest flower from the shortest flower.

8 1/4 - 6 1/2

Break off 1 from 8 : 8 1/4 = 7 5/4

Now we have:

7 5/4 - 6 1/2

Subtract whole number: 7 - 6 = 1

Combine fraction:

5/4 - 1/2 = 3/4

1 + 3/4

= 1 3/4 inches

Hence, the answer is [B] 1 3/4

In which of these examples, binomial distribution can be used? a) Finding the best month to launch a new product b) Accurately p

irina1246 [14]

Answer: The answer is (d) Accurately predicting who will be promoted at work.

Step-by-step explanation: We are given four options and asked in which of these four, we can use binomial distribution.

Binomial distribution is used in that experiments where there are only two outcomes, either success or failure.

In the given four options, (a), (c) and (d) are incorrect, because the number of outcomes are not fixed there and hence we cannot use binomial distribution.

Only option (b) will serve our purpose, as we are accurately predicting who is getting promoted at work.

Thus, the correct option is (b).

Create a word problem on Algebraic Expressions and Measurement (grade 10)

Frank can build a fence in twice the time it would take Sandy. Working together, they can build it in 7 hours. How long will it take each of them to do it alone?

Answer

If Frank and Sandy can build the fence in 7 hours, they must be building

of the fence every hour.

Now, let the amount of time it takes Sandy be

hours so that Frank takes

hours. Sandy can build

of the fence every hour and Frank can build

of the fence every hour.

We now have the following equation to solve.

10.50

Thus, Sandy takes

10.50

hours and Frank takes

hours.
