What percent increase?

Answer:

Part 1:

Make a scatterplot that represents this data. You may use a program such as Excel, or make the scatterplot by hand and scan it.

Part 2:

Does this data have a positive correlation, negative correlation, or no correlation?

Part 3:

Without the use of technology, find the equation of the line of best fit for the data. Tell which points that you used and show the steps you used to get the equation. Refer to the first 4 steps on page 2 of the lesson titled "Linear Regression - Line of Best Fit" to use as a guide.

Part 4:

Use the equation found in part 3 to predict the scores for two people who studied for 15 hours and 9 hours. Refer to the last step on page 2 of the lesson titled "Linear Regression - Line of Best Fit" to use as a guide.

Compile the results from parts 1 through 4 and put them in a Word document. Submit the document to your teacher.

Answer:

0.477121=−log(3x+7)+0.30103

Step 1: Flip the equation.

−log(3x+7)+0.30103=0.477121

Step 2: Add -0.30103 to both sides.

−log(3x+7)+0.30103+−0.30103=0.477121+−0.30103

−log(3x+7)=0.176091

Step 3: Divide both sides by -1.

log(3x+7)=−0.176091

Step 4: Solve Logarithm.

log(3x+7)=−0.176091

10log(3x+7)=10−0.176091

3x+7=0.666667

3x+7−7=0.666667−7(Subtract 7 from both sides)

3x=−6.333333

Step-by-step explanation:

The roots of an equation are simply the x-intercepts of the equation.

See below for the proof that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots

The equation is given as: [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]

There are several ways to show that an equation has real roots, one of these ways is by using graphs.

See attachment for the graph of [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]

Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)

From the attached graph, we can see that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] crosses the x-axis at approximately -2000 and 2000 between the domain -2500 and 2500

This means that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots

Answer:

The estimate is too low

Step-by-step explanation:

46×6=276 which isn't a very close estimate. However if you used 46×7=322 the estimate would be OK. Now if you used 46×8=368 that would be too high of an estimate here. In simpler terms 1 to 6 is too low of an estimate here and 8 to 9 is too high of an estimate. The number 7 is the middle ground here. Hope this helped.

Answer: 13

Step-by-step explanation:

Step-by-step explanation:

the slope is the y/x ratio of the y and x coordinate differences when going from one point to the other. and it is always the factor of x in the equation.

x changes by 4 units (from 0 to 4), y changes by -1 unit (from 3 to 2).

so, the slope is -1/4.

the intercept means the intercept with the y-axis. and that means the y value when x = 0. which is given already by the first point : 3

so, the equation is

y = -1/4 x + 3

Answer:

Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]

Step-by-step explanation:

a)

We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.

Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].

b)

We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.

Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].

So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Answer:

open left

Step-by-step explanation:

We can distribute the left side to get [tex]3x-27<-18[/tex].

We can then add [tex]27[/tex] to both sides of the equation to get [tex]3x<9[/tex].

We can finally divide both sides of the equation to get [tex]x<3[/tex].

Because it's a [tex]<[/tex] and not a [tex]<=[/tex], it is closed. And because the inequality opens to the right, it faces to the left.

So, it is a open left graph.

.:

Answer:

g = 2 1/5

Step-by-step explanation

get g by itself by canceling out the 5

whatever you do to one side you have to do to the other side.

5-5 leaves you with nothing but the g on the left side of the equals sign

7 1/5 -5= 2 1/5

so your left with g= 2 1/5

g + 5 = 7 1/5

    -5     -5

g  = 2 1/5

Step-by-step explanation:

If at June 1, 2022, Sheffield Corp. had an Accounts Receivable balance of $ 18,900. During the month, the company had credit sales of $

24,500 and collected Accounts Receivable of $ 28,500. The balance in Accounts Receivable at June 30, 2022 will be: $14,900

Using this formula

2022 Balance in Accounts Receivable=Accounts Receivable balance as on June 1, 2022+ Credit sales  -Collected Accounts Receivable

Let plug in the formula

2022 Balance in Accounts Receivable=$18,900+$24,500-$28,500

2022 Balance in Accounts Receivable=$14,900

Inconclusion if at June 1, 2022, Sheffield Corp. had an Accounts Receivable balance of $ 18,900. During the month, the company had credit sales of $
