Here is the equation:

$-15.6 = -3.9r$

Since both decimals are negative, the answer will be positive.

Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

$-15.6 \div -3.9 = -3.9r \div -3.9 \\ 4 = r$

r is equal to 4 → r = 4

2. Rainey graphed a function with exponential growth and an initial value of 15. Which of the following could represent the equa

Mars2501 [29]

Exponential equation are functions defined by $y =ab^x$

The equation that could represent Rainey graph must take the form $y =15b^x$

<h3>How to determine the equation</h3>

An exponential equation is represented as:

$y =ab^x$

Where:

a represents the initial value
b represents the rate

The initial value (a) is 15.

So, the equation becomes

$y =15b^x$

The graph is not given;

So, the equation cannot be determined.

Assume that the rate is 2.

Then the function would be: $y =15(2)^x$

Jane is trying to estimate the average electric bill amount of people who live in Las Cruces in summer time. She randomly select

Lina20 [59]

Answer:

The estimated average electric cost amount of all residents in Las Cruces = 182.9

Step-by-step explanation:

The bill amounts from the electric company for the month of July for 10 randomly selected houses from the map was obtained to be

135 265 215 103 156 203 125 156 230 241

Using the Central Limit theory, the mean of a sample extracted randomly from an independent distribution is approximately equal to the population mean of the independent distribution.

This means that the sample mean of a random sample extracted from the population is a good estimate of the population mean.

Sample mean ≈ Population mean

μₓ = μ

Mean = = (Σx)/N

The mean is the sum of variables divided by the number of variables

x = each variable

N = Sample size = 10

Σx = (135+265+215+103+156+203+125+156+230+241) = 1,829

Sample mean = (1,829/10) = 182.9

Population mean ≈ sample mean

Population mean ≈ 182.9

Hope this Helps!!!
