Answer:

22 people

Step-by-step explanation:

Using the concept of a Venn Diagram, you place the 3 people in the intersection. Then, you subtract the three from both groups to keep the balance.

Since you said "or", you just add the entirety of the population.

(16 - 3) + (9 - 3) + 3 = 22

Vivian found data about her city's population and made a scatter plot the equation of the linebbest fit for. Her data is p= 637.
Andre45 [30]

Answer:

annual growth rate m = 637.5 people / year

Step-by-step explanation:

Solution:-

- The scatter plot displaying the city's population was modeled by a linear equation of the form:

                               y = m*x + c

Where, m and c are constants.

- The scatter plot displayed the following relation of the city's population (p):

                               p = 637.5*t + 198,368.1

Where, p : The population in t years after after 1990

            t : The number of years passed since 1990.

- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:

                             dp / dt = m = 637.5

- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year

HELP ME NOWWWWWW LIKE JUST GIVE ME THE ANSWER PLEASEEEEE
Minchanka [31]

Answer:

$997

Step-by-step explanation:

Okay, so the first thing you need to do is find how much commission Luis received so that we can add that to the base salary. To do that, we could set up a proportion.

Since percentages are out of 100, we'll need to put 14 over 100. Because $6050 is the total amount he sold, we'll put that number in the denominator corresponding to the total, or 100. The proportion will look somewhat like the following:

\frac{14}{100} =\frac{x}{6050}

To find X, we have to multiply across (14 × 6050, which is 84700) then divide that by 100 (or the denominator right on the other side), which would result in 847.

So... X = $847. Now we add that to the base salary (150 + 847), and that gets us $997 for the total he was paid last week.

I apologize for taking so long to help ^-^;
