Hi Kimberlys969pdrfzz,

Question:

Find the mean

Mean - "The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are."

Solution:

\frac{10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28}{9} = \frac{180}{9} = 20

Answer:

Mean = 20

Hope This Helps!

10 + 12 + 17 + 14 + 20 + 27 + 24 + 28 + 28 = 180/9 = 20

mean: 20

a boat is traveling at an average speed of 15 meters per second. how many kilometers per minute is the boat traveling?
lukranit [14]
We know that 1 meter is 0.001 km and that 1 minute is 60 seconds.
To transform 15m/s we into km/min we have to multiply 15 by 0.001 and multiply it by 60.
15*0.001*60=0.0015*60=0.09 km/min  - its the answer

How to solve frequency distribution problems
vova2212 [387]

Example 1 – Constructing a frequency distribution table

Divide the results (x) into intervals, and then count the number of results in each interval. ...

Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.

Could someone please help me? Thank you and explain the work because I don’t get this
lesya [120]

Answer:

5.59 times per second.

Step-by-step explanation:

Direct variation is in the form:

y=kx

Where <em>k</em> is the constant of variation.

Inverse variation is in the form:

\displaystyle y=\frac{k}{x}

In the given problem, the frequency of a vibrating guitar string varies inversely  as its length. In other words, using <em>f</em> for frequency and <em>l</em> for length:

\displaystyle f=\frac{k}{\ell}

We can solve for the constant of variation. We know that the frequency <em>f</em> is 4.3 when the length is 0.65 meters long. Thus:

\displaystyle 4.3=\frac{k}{0.65}

Solve for <em>k: </em>

<em />k=4.3(0.65)=2.795<em />

<em />

So, our equation becomes:

\displaystyle f=\frac{2.795}{\ell}

Then when the length is 0.5 meters, the frequency will be:

\displaystyle f=\frac{2.795}{.5}=5.59\text{ times per second.}

Choose all the lengths that are equal to 3 yards 16 inches.
kodGreya [7K]

Answer:

A: 124 in

D: 2 yd 52 in

E: 10 ft 4 in

Step-by-step explanation:

we know that

1 ft=12 in

1 yd=36 in

we have

3 yd 16 in

Convert to inches

3 yd 16 in=3(36)+16=124 in

<em>Verify each case</em>

case A) 124 in

124 in=124 in ------> is true

therefore

124 in is equal to 3 yd 16 in

case B) 4 yd 4 in

Convert to inches

4 yd 4 in=4(36)+4=148 in

124 in=148 in ------> is not true

therefore

4 yd 4 in is not equal to 3 yd 16 in

case C) 3 yd 1 1/2 ft

Convert to inches

3 yd 1 1/2 ft=3(36)+1.5(12)=126 in

124 in=126 in ------> is not true

therefore

3 yd 1 1/2 ft is not equal to 3 yd 16 in

case D) 2 yd 52 in

Convert to inches

2 yd 52 in=2(36)+52=124 in

124 in=124 in ------> is true

therefore

2 yd 52 in is equal to 3 yd 16 in

case E) 10 ft 4 in

Convert to inches

10 ft 4 in=10(12)+4=124 in

124 in=124 in ------> is true

therefore

10 ft 4 in in is equal to 3 yd 16 in
