If the distance is 1.5 from -2, then it could be 1.5 less than -2 or 1.5 more than -2, so we know that we will have two points on the number line.
Let’s first find 1.5 less than -2
We will subtract 1.5 from -2
-2-1.5 = -3.5
Our first value of n will be -3.5
Next let’s find 1.5 more than -2
We will add 1.5 to -2
-2+1.5 = -0.5
Our second value of n will be -0.5
Our answers will be -3.5 and -0.5

<u>Given</u>:
Given that the pie chart shows the relative frequency distribution resulting from a survey of 6000 US rural households with internet connections in a certain year.
We need to determine the total number of households with each type of internet in the survey.
<u>Cable modem:</u>
Since, the relative frequency distribution for cable modem is 0.142
The total number of households that use cable modem is given by
![0.142 \times 6000=852](https://tex.z-dn.net/?f=0.142%20%5Ctimes%206000%3D852)
Thus, 852 households use cable modem.
<u>DSL</u>:
Since, the relative frequency distribution for DSL is 0.092
The total number of households that use DSL is given by
![0.092 \times 6000=552](https://tex.z-dn.net/?f=0.092%20%5Ctimes%206000%3D552)
Thus, 552 households use DSL.
<u>Dialup</u>:
Since, the relative frequency distribution for dialup is 0.747
The total number of households that use dialup is given by
![0.747 \times 6000=4482](https://tex.z-dn.net/?f=0.747%20%5Ctimes%206000%3D4482)
Thus, 4482 households use dialup.
<u>Others</u>:
Since, the relative frequency distribution for others is 0.019
The total number of households that use others is given by
![0.019 \times 6000=114](https://tex.z-dn.net/?f=0.019%20%5Ctimes%206000%3D114)
Thus, 114 households use others.
Answer:
Step-by-step explanation:
Using provided formula and filling in the variables:
z = ![\frac{(0.6-0.7)-(0)}{\sqrt{\frac{0.615782*0.384218}{88}+\frac{0.615782*0.384218}{82} }}](https://tex.z-dn.net/?f=%5Cfrac%7B%280.6-0.7%29-%280%29%7D%7B%5Csqrt%7B%5Cfrac%7B0.615782%2A0.384218%7D%7B88%7D%2B%5Cfrac%7B0.615782%2A0.384218%7D%7B82%7D%20%7D%7D)
Filling in in calculator:
z ≈ -1.34
