How much greater is 42 inches than
1 yard? Explain.

Answers

Answer:

6 inches

Step-by-step explanation:

1 yard =36 inches

36 inches< 42 inches

42-36 inches = 6 inches

Answer:

.1666676

Step-by-step explanation:

1 in = 0.0277778 yard

42  × 0.0277778 = 1.1666676

1.1666676 - 1 = .1666676

so 42 inches is .1666676 greater than 1 yard

John recorded the weight of his dog Spot at different ages as shown in the scatter plot below.




Part A:
Write an equation that would describe the line of best fit.


Part B:
Using the line of best fit, make a prediction of Spot's weight after 18 months.

Answers

Answer:

A) y = 1.875x + 1.25

B) 35 pounds

Step-by-step explanation:

A) We need two points to define a line. To find an equation that would describe the line of best fit, we can use one of the first points and one of the last points. Let's use (2, 5) and (10, 20).

General equation of a line:

y = mx + b

Slope of the line:

m = (20 - 5)/(10 - 2) = 1.875

y-intercept is found replacing a known point and the slope into the general  equation:

5 = 1.875*2 + b

b = 5 - 1.875*2 = 1.25

The final equation is:

y = 1.875x + 1.25

where y represents weight (in pounds) and x represents age (in months)

B) At x = 18:

y = 1.875*18 + 1.25 = 35

Collete mapped her vegetable garden on the graph below. Each unit represents 1 foot.
Collete plants an 8-foot row of lettuce in the garden. Which points could tell where the row of
lettuce starts and ends?
(-1,-6) and (8, –6)
(-4, -1) and (-4,7)
(-6, -1) and (-6,8)
(-1,-4) and (7,-4)
Help pls

Answers

Answer:

(-4,-1) and (-4,7)

Step-by-step explanation:

If Collete planted a row of lettuce, that means their coordinates must have the same vertical coordinate, or the same horizontal coordinate. Another important characteristic is that between those points, there must have 8 units of separation, because it's an 8-foot row.

Only the first choice offers these characteristic to properly represent the row of plants with 8 feet distance between the first and the last plant.

Therefore, the answer is (-4,-1) and (-4,7)

what is the equation of the line passing through ( -5, -3 ) and perpendicular
to the line representing the equation y = - 5/7x + 2?

Answers

Answer:

y = 7/5x + 4

Step-by-step explanation:

use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.

(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4

An SUV costs $25,000. Their is 3% tax. How much will the SUV costs with tax?

Answers

Answer:

$25,750

Step-by-step explanation:

25000 x 3%=750

25000+750

Answer:

25,750.

Explanation:

Step one: Find what 3 percent of 25000 is.

25000 divided by 3 (tax percentage)

3% of 25,000 =750

Step two: add that to the original cost of the SUV.

25,000 (original cost) + 750 (3% of original cost) = 25,750

The points (-16,r) and (-4,11)lie on a line with slope 1/2. Find the missing coordinate r?

Answers

Answer: The missing coordinate R is 5.

Step-by-step explanation:

11=1/2(-4) + B

11=-2 +B  

B= 13

B represents the y-intercept

so we will use the equation y=mx + B  and we know the slope and y intercept.

r= 1/2(-16) + 13

r= 5

Answer:

26

Step-by-step explanation:

The mean absolute deviation of the data is 11.

The mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values.

Given: The data below show the weights, in pounds, of a group of professional football players.

325, 310, 289, 288, 285, 285, 285, 280, 280, 273

The mean of the data set is 290 pounds.

How to find the mean absolute deviation of the data

set, to the nearest whole number?

The average absolute deviation is

[(325-290)+(310-290)+|(289-290)|+|(288-290)|+3|(280-290)|+21(280-290)|+|(273-290)|]/10

=> (35+20+1+2+5+5+5+10+10+17)/10

=> 11.
