<h3>Answer: D) $16.77</h3>

=====================================================

Explanation:

The meter goes from 9854 to 0023. You can think of 0023 as 10023 (even though the meter only has 4 digits, so it rolls over to start over again).

So,

10023 - 9854 = 169

This means 169 kw hours of electricity are used for the month of December.

The first 100 kw hours costs $4.35

There are 169-100 = 69 kw hours left, and they cost $0.18 each, so we add on 69*0.18 = 12.42 getting 4.35 + 12.42 = 16.77

Let N be the number of data entries in a population and n be the number of data entries in a sample data set. Describe the diffe

Shkiper50 [21]

Answer:

Step-by-step explanation:

During the calculation of any population standard deviation, the sum of the squared deviation is usually divided by N, which is the number of data entry in the population. Thereafter, the square root of the result would be taken.

On the other hand, during the calculation of the sample standard deviation, the sum of the squared deviations is usually divided by n - 1, with n being number of entries in the sample data set. Thereafter, the square root of the result would be taken.

Find the zero(s) of the rational expression below. fraction numerator 5 x squared plus 26 x plus 24 over denominator 3 x squared

SVETLANKA909090 [29]

For this case we have the following rational expression:
$\frac{5x^2 + 26x + 24}{3x^2 + 10x - 8}$
What we must do for this case, is to factor the numerator and the denominator.
We have then:
$\frac{(5x+6)(x+4)}{(3x-2)(x+4)}$
Then, canceling similar terms we have:
$\frac{(5x+6)}{(3x-2)}$
Then, the function is not defined for the values that make the denominator zero.
We have then:
$3x-2 = 0

3x = 2

$
$x = \frac{2}{3}$
And on the other hand, a zero of the function is:
$5x+6 = 0

5x = -6$
$x = \frac{-6}{5}$
Answer:
a zero of the function is:
$x = \frac{-6}{5}$
the function is not defined for the value:
$x = \frac{2}{3}$
