The population of Austin, Texas in 1980 was 346,000 people. The population in 1990 was 472,000 people. What is the rate of change of the population with respect to the year for this function?
Answer:
12.6 thousand a year
Step-by-step explanation:
take the 346 add 126 thousand to it equaling a good 472 thousand divide 126 thousand by 10 cause it is a ten year span that equals you get 12.6 thousand.
I need brainliest please
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.

Three out of five people surveyed said that Shrek 2 is better than Shrek 3 and Shrek 4. If a total of 560 people are surveyed, how many would you expect to agree that Shrek 2 is better?
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.

Students in the science lab are measuring the mass of an object on a triple beam balance. The object has a mass of 38 grams. Complete the table below with the absolute and percent error for each students’ measurement. Round your answer to the nearest tenths place.
Answer:
The answer is 40
Step-by-step explanation:
have a nice day!
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.
What is the percentage?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].

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, are green. How many red key chains are inside the bin?
A.
26
B.
35
C.
126
D.
189
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

What is the x and y intercept of the following function
y=1-x
Please help me ASAP
I will give brainliest
Answer:
-23
Step-by-step explanation:
rearrange to point slope form first
slope can be fine by y2-y1/x2-x1 (im using the first 2 points)
so 13-25 = -12 and -54-(-72) = 18, and the slope is -12/18 which is -2/3
then you can use any point (i used the first point) to create the point slope form which is y-ypoint=slope(x-xpoint) and equation would be y-25=-2/3(x+72)
turn it into slope intercept form by multiplying -2/3 within the equation and adding -25 on both sides
you will get y= -2/3x-23
and the y intercept will be (0, -23)
