Find the equation of the line that passes through (-3,1) and is parallel to y = 1 − 2 x . Leave your answer in the form y = m x + c

Answers

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y - 1 = 0 ( subtract 3x - 1 from both sides )

y = - 3x + 1 ← in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (1, 4) into the partial equation

4 = - 3 + c ⇒ c = 4 + 3 = 7

y = - 3x + 7 ← equation of line in form y = mx + c

Sandy worked extremely hard at her job and earned a large bonus at the end of the year. She decided to give her children 2/5 of the money and her grandchildren 1/4 of her bonus. How much of her bonus did she keep for herself?

Answers

Answer:

7/20 of her bonus

Step-by-step explanation:

Solution:

She gives her children 2/5 of her bonus and grandchildren 1/4 of her bonus.

= 1 - 2/5 - 1/4

= 1 - 8/20 - 5/20

= 1 -13/20

in 2012, the general social survey included a question that asked participants how many hours they worked a week. do males work more hours at a job than females? would this be an example of independent or dependent samples?

Answers

Using sampling concepts, it is found that this is an example of independent samples.

For dependent samples, there is a paired measurement for one set of items.For independent samples, separate measurements are made on two different sets, that is, the value on one sample reveal no information about the values on the other sample.

In this problem, there are two samples, the sample composed of male workers and the one composed of female workers, and separate measurements are taken, hence, it is an independent sample.

The product of 7 and a number is greater than 42. If the number is a whole number less than 10 , what could the number be?

Answers

Answer:

8 or 9

Step-by-step explanation:

Your primary equation that they gave you is ?b and has to be greater than ?a 7 x ?a =42

So your answer to ?a is 7 because 7 x 7 =42 therefore your answer to ?b has to be 8 or above.

the next part of your problem states that it is a whole number UNDER 10.... this limits your possible answer to either 8 or 9.

Suppose that Ana picks a name, replaces it, and picks a name again.

What is the probability that NEITHER of the students selected are
9th graders?
Round your answer to two decimal places.

Answers

Answer:

P(Neither 9th grade)=16/28*16/28=16/28*16/28=(16/28)^2=256/784≈0.3265

Answer:

The probability that neither of the students selected are 9th graders is about 0.33.

Step-by-step explanation:

Pls give brainliest

Probabilities are used to determine the chances of events

The probability that neither of the students is a 9th grader is 0.33

From the table, the number of students that are not 9th graders are:

[tex]N9 =9 + 7[/tex]

[tex]N9 =16[/tex]

The total number of students is:

[tex]Total =12 + 9 + 7[/tex]

[tex]Total =28[/tex]

The probability that neither of the students is a 9th grader is calculated as follows

[tex]P =P(N9) \times P(N9)[/tex]

So, we have:

[tex]P =\frac{16}{28} \times \frac{16}{28}[/tex]

Multiply

[tex]P =\frac{256}{784}[/tex]

Divide and approximate

[tex]P =0.33[/tex]

Hence, the probability that neither of the students is a 9th grader is 0.33

What does a residual value of â€""0. 8 mean in reference to the line of best fit?.

Answers

Residuals are used to determine how the line of best fit relates to the data points

A residual value of -0.8 means, the point is 0.8 units above the line of best fit

The residual value is given as:

[tex]\mathbf{Residual = -0.8}[/tex]

When the residual value is less than 0 (i.e. negative), then the point is above the line of best fit.

So, the interpretation of a residual value of -0.8 is that, the point is 0.8 units above the line of best fit
