Frank says that 2/10 of the grid below is shaded. Kendra says that 20/100 of the grid is shaded. Who is correct and why?

Answers

Answer:

They are both correct because each fraction can simplify down to 1/5.

If you divide 2/10 by 2 you get = 1/5

Divide 20/100 by 20 to get = 1/5

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?

Answers

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.

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.

Answers

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.

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.

What is the affect on the graph of the linear parent function f(x) equals X when FX is replaced by FX +3

Answers

Answer:

The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).

Step-by-step explanation:

We know that when we add a constant to the input of the parent function, we get a horizontal shift.

The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.

For example, consider the function

f(x)

so adding [tex]3[/tex] in the put i.e. [tex]f(x+3)[/tex] would be a change on the inside of the function, giving a horizontal shift left by 3.

Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).

A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P ( red or blue)

Answers

Answer:

5/8

Step-by-step explanation:

To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.

Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.

[tex]\frac{10}{16} = \frac{5}{8}[/tex]

As we cannot simplify 5/8 any further, this is the final answer.

Noah has a coupon for 30% off at his favorite clothing
store. He uses it to buy a hoodie and a pair of jeans.
Noah paid $28 for the jeans after using the coupon.
What is the regular price of the jeans?

Answers

Answer:

$21.54

Step-by-step explanation:

price paid    = regular price ( 1 + coupon in percent)

             $28 = regular price x (1.3)

regular price = $28 / 1.3

                     = $21.54

           

The regular price of the jeans is equal to $93.33.

Let the cost price be C.

Given the following data:

Coupon = 30%Selling price = $28

To calculate the regular price of the jeans:

Since Noah had a coupon for 30% off, it simply means that he would get a discount of 30% for any clothing he buys at his favorite clothing store. Thus, the cost price of the jean multiplied by 0.3 would give the amount of money to be paid by Noah, which is $28.

Mathematically, the selling price is given by:

[tex]28 = \frac{30}{100} \times C\\\\2800 =30C\\\\C=\frac{2800}{30}[/tex]

C = $93.33

At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.
