<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
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
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
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
Thus, 114 households use others.

Step-by-step explanation:
Step-by-step explanation:
For a moment let y = x^2 + 5
Then by the distributive property
(2x^2 + 4x - 3 ) P = . 2x^2p + 4xp - 3p
Again by the distributive
2x^2 p = 2x^2(x^2 - 2x +5) = 2x^4 - 4x^3 + 10x^2
4xp = 4x(x^2 + 5) = 4x^3 - 8X^2 +20x
-3p = -3(x^2 - 2x + 5) = -3x^2 + 6x -15
Taking everything together we get
(2x^2 + 4x -3 )(x^2-2x + 5) = (2x^4 -4x^3 +10X^2) + (4x^3 - 8x^2 + 20) + -3x^2 + 6x -15)(2X^2 + 4x - 3 )(x^2 -2x = 5) = 2x^4 + 26 - 15
Answer:
C
Step-by-step explanation:
She spent $102.44 in total.
She spent $36.44 on cookies.
And $11 per box of cupcakes.
This means that she knows the exact amount she spent on cookies and in total so now to find out how much she spent on cupcakes, she subtracts $36.44 from $102.44($66) and then divides 66 by 11(6). So if you needed the problem solved x=6.
