We want to find the rate of change of the population of Austin, Texas in the years between 1980 and 1990.

The answer is: r = 12,600 people/year.

We will assume that this increase in population is modeled with a linear equation, remember that a general linear equation is:

y = a*x + b

Where the rate of change, or slope, is a.

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope is given by the formula:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

For this case we have two points, these are:

(1980, 346,000)

(1990, 472,000)

Then the slope or rate of change is just:

[tex]a = \frac{472,000 - 346,000}{1990 - 1980} = 12,600[/tex]

To be complete we need to add the correspondent units, which are people per year.

Then the rate of change is:

r = 12,600 people/year.

Answer:

c.126 red

Step-by-step explanation:

red+green+yellow=350

10% out of 350 are yellow

0.1 times 350=35

350-35=315

3/5 out of 315 are green

red is not green so

2/5 of what is left is red

2/5 of 315 is red

2/5 times 315=430/5=126

126 red

Answer:

Shrek 2 IS better than the other 2 because THE OTHER TWO HAS NO PLOT!!

Answer:

336

Step-by-step explanation:

To find the answer, we will cross multiply.

3         ?

5       560

We will first multiply 3*560.

= 1680

Next, we will divide our previous answer by 5.

1680/5= 336

therefore, you would expect 336/560 people to like Shrek 2 better than 3 and 4.

The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Actual mass = 38

Danielle error = 40 - 38 = 2 grams

% error = 2/40 x 100 = 5%

Iris error = 4 - 34 = 6 grams

% error = 6/40 x 100 = 15%

HB error = 41 - 40 = 1 grams

% error = 1/40 x 100 = 2.5%

Hence "The absolute error of Danielle, Iris, and HB is 2,6 and 1 gram respectively. The percentage error of Danielle, Iris, and HB  are 5%,15%, and 2.5%  respectively".

Answer:

The slope is  [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

If you graph out the points on a line, you can clearly see that the rise between the points on the graph is 2, while the run is 4. This would give you [tex]\frac{2}{4}[/tex], so if you simplify the fraction, you would get [tex]\frac{1}{2}[/tex].
