a. Without making scatterplots, find the correlation and the least-squares regression line for all four data
sets. What do you notice? Use the regression line to predict y for x = 10.
b. Make a scatterplot for each of the data sets and add the regression line to each plot.
c. In which of the four cases would you be willing to use the regression line to describe the dependence of
y on ar? Explain your answer in each case.

What to do?

Solution:

The equation has only one variable i.e. m. For finding m we need to isolate it any one side of the equation. Before that, let's expand the parentheses,

⇒ 6(m - 1) = 3(3m + 2)

⇒ 6m - 6 = 9m + 6

Now moving m to the left hand side and constant terms to the right hand side,

⇒ 6m - 9m = 6 + 6

⇒ -3m = 12

Dividing the Equation by -3,

⇒ m = 12 / -3

⇒ m = -4

Thus, the required value of m is -4.

Answer:

4

Step-by-step explanation:

1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.

Complete Question

A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20​

Answer:

$7

Step-by-step explanation:

From the question we are told that :

Any 4 entrees = $20,

And there is a discount of $2 per entree.

Let us represent the original average cost of entrees as = a

Hence, we have the algebraic expression

4(a - 2) = 20

4a - 8 = 20

4a = 20 + 8

4a = 28

Divide both sides by 4

4a/4 = 28/4

a = 7

Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.

Answer:

first one is 2.2mm/year and second is 6.2years and -2.2mm/year

Step-by-step explanation:

plz trust me i just did it

The decimals in the problem should be represented as a negative rate is -2.2mm/year

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

Ericka is also in Mr. Whittaker’s science class and she recorded the variation in water level at a different part of the river.

Ericka should first one is 2.2mm/year and the second is 6.2years and -2.2mm/year

Thus, the decimals in the problem should be represented as a negative rate is -2.2mm/year

Answer:

The sum is -1/2

Step-by-step explanation:

Your question is not too clear to me but if I reframe it, it will turn to this;

Find the sum of In{1 - (1/n^2)} for n >= 2

£n>=2 = In{1 - (1/2^2)} + In{1 - (1/3^2)} + In{1 - (1/4^2)} + ......

£n>=2 = In{1 - (1/4)} + In{1 - (1/9)} + In{1 - (1/16)}

£n>=2 = In(3/4) + In(8/9) + In(15/16)

£n>=2 = -0.287 + -0.117 + -.064 = −0.468

£n>=2 = -0.5 by approximation

£n>=2 = -1/2 is the sum and by evaluation it converge.

Answer:

His extra pay would be of $79.69

Step-by-step explanation:

Assuming that the clerk works regular 40 hour per week, then he has worked 6.25 extra (overtime) hours this week. Then his extra pay for overtime work would be:

6.25 times $12.75 = $79.69

Answer:

g= −6/13o5

Step-by-step explanation:

Let's solve for g.

−3−(−8)−(−2)=x0−13ogo3o

Step 1: Flip the equation.

−13go5+1=7

Step 2: Add -1 to both sides.

−13go5+1+−1=7+−1

−13go5=6

Step 3: Divide both sides by -13o^5.

−13go5

−13o5

=6−13o5

g=−6/13o5

Answer:

L = (14x+33) inches.

Step-by-step explanation:

We know that,

1 feet = 12 inches

For example,

2 feet = 12(2) inches

Now, the length of one board is (x+3) feet

The length of second board is (2x-3) inches

We can convert length into inches as follows :

l = (x+3) feet

l= (x+3)(12) inches

l = 12x+36 inches

It means, total length,

L = 12x+36 inches + (2x-3) inches

L = (14x+33) inches.

Answer:

The table shows conversions of common units of length.

Answer:

92

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the expression chase was asked to simplify as [tex](-3) ^ 4 * (-3) ^ 9[/tex], lets first solve and compare our solution with chases's

Using the law of indices [tex](a) ^ m * (a) ^ n = a^{m+n}[/tex]

[tex]= (-3) ^ 4 * (-3) ^ 9 \\\\= (-3)^{4+9}\\\\= (-3)^{13}[/tex]

Chases reasoning is wrong according to his answer [tex](-3) ^ 4 * (-3) ^ 9 = (-3)^ {36}[/tex]. What chase's did was to multiply the power of -3 together instead of adding. In indices when the bases are equal and we are multiplying, the powers of the bases will be added not multiplies=d as chase's did.
