How do rented housing units differ from units occupied by their owners? Here are the distributions of the number of rooms for ow

IrinaK [193]

Answer:

Standard deviation for owner-occupied units

2.9797

Standard deviation for renter-occupied units

3.1594

Step-by-step explanation:

Let us find first the mean. This is the distribution expected value or expectancy.

Mean for owner-occupied units

0.003 + 2*0.002 + 3*0.023 + 4*0.102 + 5*0.209 + 6*0.223 + 7*0.201 + 8*0.149 + 9*0.053 + 10*0.035 = 6.293

To compute the variance for owner-occupied units, we add these values

$(1-6.293)^2+(2-6.293)^2+(3-6.293)^2+(4-6.293)^2+(5-6.293)^2$

$+(6-6.293)^2+(7-6.293)^2+(8-6.293)^2+(9-6.293)^2+(10-6.293)^2$

then divide by 10 and take the square root to get the standard deviation 2.9797

Mean for renter-occupied units

0.008 + 2*0.027 + 3*0.287 + 4*0.371 + 5*0.155 + 6*0.090 + 7*0.043 + 8*0.013 + 9*0.003 + 10*0.003 = 4.184

To compute the variance for renter-occupied units, we add these values

$(1-4.184)^2+(2-4.184)^2+(3-4.184)^2+(4-4.184)^2+(5-4.184)^2$

$+(6-4.184)^2+(7-4.184)^2+(8-4.184)^2+(9-4.184)^2+(10-4.184)^2$

then divide by 10 and take the square root to get the standard deviation 4.184

Guided Practice

Allisa [31]

Answer:

1) NP

2) P

3) NP

4) P

5) P

Step-by-step explanation:

re-write all the pairs into fractions

1.) $\frac{4}{6} =\frac{20}{24}$ {4 x 5 = 20} and {6 x 4 = 24} 5 ≠ 4

(basically both the underlined numbers need to be the same)

I can do an explanation for each one if you need; just comment, cause I'll be on here for a while. Good luck! :D

What is the x-coordinate at the point of intersection for these equations? f(x) = 2.8x - 12 g(x) = 5.8x + 9

ratelena [41]

For this case we have the following equations:
f (x) = 2.8x - 12
g (x) = 5.8x + 9
We must equalize the equations.
We have then:
f (x) = g (x)
2.8x - 12 = 5.8x + 9
We clear x:
x (5.8-2.8) = -12 - 9
3x = - 21
x = -21 / 3
x = -7
Answer:
The x-coordinate at the point of intersection for these equations is:
x = -7
