The population of a certain inner-city area is estimated to be declining according to the model P(t)=385,000e−0.022t, where t is the number of years from the present. What does this model predict the population will be in 9 years? Round to the nearest person.
Answer:
This model predicts that population will be 315,842 in 9 years.
Step-by-step explanation:
Let the population of the city be represented by the function [tex]p(t) = 385,000\cdot e^{-0.022\cdot t}[/tex], where [tex]t[/tex] is the number of years from the present. The negative exponent means that such city is expected to experiment a sustained decrease. The predicted population in 9 years is determined by evaluating the function at [tex]t = 9[/tex]:
[tex]p(9) = 385,000\cdot e^{-0.022\cdot (9)}[/tex]
[tex]p(9) = 315,842.394[/tex]
[tex]p(9) = 315,842[/tex]
This model predicts that population will be 315,842 in 9 years.

When the errors show a non-random pattern in a residual plot, that means that your model probably is not appropriate for linear regression. True or false and why?
Answer: True
The errors represent how far off the guess is to the true value. The points on the residual plot must be scattered randomly around 0, in both positive and negative regions. Ideally, the smaller the errors, the better the fit. So we want these errors to be as close to 0 as possible. This is why we try to minimize the sum of the squared error (SSE) when trying to find the linear regression equation. The r and r^2 value are related to this idea as well.
If we don't have randomly scattered errors, and some pattern shows up, then this means a linear equation is not a good fit. Another model such as a quadratic model may be the better option.
As for the "why" this works, try to think of a person throwing darts. Their accuracy isn't perfect so they'll likely miss on the left and right sides of the target. Stuff on the left is negative territory, while stuff on the right is positive. Each side is fairly equal assuming the thrower isn't biased in some way. That's why we have randomly scattered points in both regions. In the case of a regression line, that's where our guess goes while the actual data point is the observed value. The difference between the two is the error.
What is the slope of a line parallel to y=1/3x + 2 explain.
Answer:
1/3
Step-by-step explanation:
since you're finding the parallel it would have the same slope since it is parallel and since this equation is already in slope-intercept form, you can see that 1/3 is the slope

The graph shows a proportional relationship between the cups of flour a baker uses and the number of cookies made.
A. What does the point (0,0) represent in the situation?
B. What does the point( 1, 18) represent?
Answer:
Step-by-step explanation:
(0,0)A baker doesn't use any cups of flour so he can't make any cookies
(1,18)A baker uses 1 cup of flour and makes 18 cookies
(0,0)A baker doesn't use any cups of flour so he can't make any cookies
(1,18)A baker uses 1 cup of flour and makes 18 cookies.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given graph is a proportional relationship between the cups of flour a baker uses and the number of cookies made. proportional relationship graph means the slope of the graph will be same.

I need help with finding x
ill give brainiest to whoever shows work
Answer:
x=-5
Step-by-step explanation:
-3-(7x+5)+9x=x-8+3x+10
Distribute the -1 to the terms in parentheses.
-3-7x-5+9x=x-8+3x+10
Combine like terms on both sides.
-8+2x=4x+2
Add 8 to both sides.
2x=4x+10
Subtract 4x from both sides.
-2x=10
Divide both sides by -2
x=-5

Which describes the first step in solving the equation 4x - 7 = -15?
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
