Answer:

Shorter piece is 3 ft, longer piece is 8 ft

Step-by-step explanation:

Set up two equations...

Let x be the length of the shorter piece, and let y be the length of the longer piece.

The whole board is 11 feet long, so

x + y = 11

He wants the longer piece to be 4 feet less than 4 times the length of the shorter board, so

y = 4x - 4

Substitute the second equation into the first equation....

x + 4x - 4 = 11           (y becomes 4x - 4)

Now solve for x

5x = 15                 (combine like terms, add 4 to both sides)

   x = 3                (divide both sides by 5)

Now substitute 3 in for x in either equation and solve for y...

y = 4(3) - 4

    y = 12 - 4

            y  =  8

Identify the mean, median, and mode for the dot plot below.01 2 3 4MathBits.comNumbers of Brothers and SistersMeanMedianMode =
telo118 [61]

The mean, median and mode is 2 of the given data from the dot plot.

Given, the table is :

Number of brothers and sisters  0,0,1,1,1,2,2,2,2,2,3,3,3,4,4

First the mean

Mean = average which = sum of data points / # of data points

Sum of data points = 0+0+1+1+1+2+2+2+2+2+3+3+3+4+4 = 30

# of data points ( count the number of dots ) = 15

So average (mean) = 30/15

= 2

Next lets find the median.  

The median is the middle value.

We can find the median by listing the values and then meeting at the middle of the values

So we have 0,0,1,1,1,2,2,2,2,2,3,3,3,4,4

the list is odd, so we use median = n+1/2

= 15+1/2

= 16/2

= 8th term

= 2

Mode is simply the value that appears most.

The value that appears the most is 2 as it appears five times which is the most out of any other value.

Hence we get the mean, median and mode.

Please anybody help me in this
Simora [160]

Answer:

<h2>a) 0.38</h2><h2>b) 0.62</h2><h2>c) 0.78</h2><h2>d) 0.03</h2><h2>e) 0.02</h2><h2>f) 0.62</h2><h2>g) 0.38</h2>

Step-by-step explanation:

a)

Probability of a owner to be moved = \frac{total owner}{total Americans} = \frac{14.8}{39} = 0.379 ≅ 0.38

b)

Probability of a renter to be moved = \frac{total renters}{total Americans} = \frac{24.2}{39} = 0.62

c)

Probability of a person who moved in the same state = \frac{Persons who moved to the same state}{Total Americans} = \frac{30.4}{39} = 0.779 ≅ 0.78

d)

Probability of a person who moved to a different country = \frac{Total moved to different country}{Total Americans} = \frac{1.3}{39} = 0.033 ≅0.03

e)

Probability of a owner who moved to a different country = \frac{Owners that moved to different country}{Total people who moved to different country} = \frac{0.3}{14.8} = 0.02

f)

Probability of a renter moving in the same state = \frac{Renter that moved in the same state}{Total persons moved in the same state} = \frac{18.7}{30.4} = 0.615 ≅ 0.62

g)

Probability of an owner moved to different state = \frac{Owners moved in different state}{Total moved in different state} = \frac{2.8}{7.3} ≅0.38

Which of the following is an equation of the line that passes through the point (−2, 3) and is perpendicular to the graph of the
Ludmilka [50]

The equation of the line is y=-\frac{1}{3}+\frac{7}{3}

Explanation:

The given equation is y=3 x-2

<u>Slope:</u>

Since, the equation of the line is perpendicular to the equation y=3 x-2, then, the slope is given by

m=-\frac{1}{3}

Hence, the slope is m=-\frac{1}{3}

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y-y_1=m(x-x_1)

Substituting the point (-2,3) and the slope m=-\frac{1}{3}, in the above formula, we get,

y-3=-\frac{1}{3}(x+2)

Simplifying, we get,

y-3=-\frac{1}{3}x-\frac{2}{3}

     y=-\frac{1}{3}x-\frac{2}{3}+3

     y=-\frac{1}{3}+\frac{7}{3}

Therefore, the equation of the line is y=-\frac{1}{3}+\frac{7}{3}
