A set of data has the following linear regression equation:= 1 + 3x

What does the equation predict for a value of x = 13?

A. y = 40
B. y = 38
C. y = 4
D. y = 9

Answers

Answer 1
Answer: We put in 13 as the value for x:


y = 1 + 3(13)


y = 1 + 39

y = 40

A bag of chips costs $3.79 including tax Mr.Connor wants to purchase chips for his class and has a $15 budget. Write and inequality to solve for the number of bags of chips Mr.Connor can purchase with his budget A. $15x > $3.79 B.$15x < $3.79 C $3.79 > $15 D. $3.79 < $15 (There is a flat line under all the greater than and less than signs)

Answers

The inequality equation that could best express the statement will be letter d. 3.79x < 15. This is because there is only 15 budget from Mr. Connor, and his spending must not exceed the budget. Then the price per pack is 3.79, so it is express as 3.79x.

Answer:

D.3.79x\leq 15

Step-by-step explanation:

We are given that

Cost of one bag of chips including tax=$3.79

Mr.Connor  has  budget=$15

We have to write an equality to  solve for the number of bags of chips can purchased by Mr.Connor with his budget.

Let x be the number of bags of chips

According to question

3.79x\leq 15

Hence, option D is true.

Answer:D.3.79x\leq 15

Which of the following values are solutions to the inequality -5 ≤ x + 5? A) -7 B) -10 C) -3

Answers

Answer:

x ≥ -10

Step-by-step explanation:

We can solve the given inequality for the variable x by subtracting 5 from both sides:

-5 ≤ x + 5

- 5        - 5

-10 ≤ x

Optionally, we can swap the sides and flip the sign:

x ≥ -10

Further Note

The '≥' sign means "greater than or equal to", which means that the variable being compared can be either the exact value of the constant or anything greater than it.

Draw the graph of the line: with a slope of -1/2 and that passes through the origin

Answers

To draw the graph of a line with a slope of -1/2 that passes through the origin (0, 0), we can use the slope-intercept form of a linear equation, which is y = mx + b, where 'm' is the slope and 'b' is the y-intercept.

In this case, the slope (m) is -1/2, and since the line passes through the origin, the y-intercept (b) is 0.

So, the equation of the line is y = (-1/2)x + 0, which simplifies to y = -1/2x.

Now, to plot the graph, start at the origin (0, 0). Since the y-intercept is 0, the line passes through the origin itself.

Next, use the slope (-1/2) to find other points on the line. The slope represents the change in y divided by the change in x. So, for every increase of 2 units in the x-direction (rise), the y-value decreases by 1 unit (run).

Plot additional points using this information and draw a straight line through all the points. The resulting graph is a downward-sloping line passing through the origin, representing the equation y = -1/2x.
