The scatter plot and line of best fit below show the length of 9 people's femur (the long leg bone in the thigh) and their height in centimeters. What is the meaning of the xx-value on the line when y=160y=160?

Answers

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The true statement is (d) The expected height of 160 cm when the femur length has a length of 42.5 cm

How to interpret the scatter plot?

From the given figure, we have:

x values represents the femur length in centimetersy values represents the height in centimeters

So, when the y value is 160, the x value is:

The expected height of 160 cm when the femur length has a length of 42.5 cm

Hence, the true statement is (d)

Explain the difference between parallel and perpendicular slope in fewer than twenty words.

Answers

Answer:

parallel refers to two equidistant lines, Because the lines are equally distant, they have the same slope and the angle between them is zero. On the other hand, when two lines intersect at a right angle, they are called perpendicular.

Answers

Answer:

Angles B & C both = 157 degrees .

Step-by-step explanation:

Angle A is adjacent to Angle B, which means they are the same size. 23 degrees for A & B.

23+23 = 46.

We have two straight lines, one line = 180. 180*2 = 360.

Take 46 from 360 because we already figured out two angles.

360 - 46 = 314

Divide 314 by 2 because we have two unknown angles...

314 / 2 = 157 .

Angle B & C = 157.

Ahmed And Ebrahim are recording how far a ball rolls down a ramp during each second. the table below shows the data the have collected.

Answers

Answer:

Read below for the answer :)

Step-by-step explanation:

So, when you read it at first, it doesn't seem to match in any way. Well look at it from left to right. If you take notice of the bottom numbers, 1 to 9 is a difference of 8. And 2 to 13 = a difference of 11. 8-11 = a plus 3 system. Likewise, 3 to 17 = 14, or, 11 +3.

The answer is yes, and that is the reason above :)

Is there a relationship between the percent of high school graduates in each state who took the SAT and the state’s mean SAT Math score? Here is a residual plot from a linear regression analysis that used data from all 50 states in a recent year
A residual plot shows “Percent of high school graduates taking the SAT” along the horizontal axis ranging from 0 to 90 in increments of 10 and “Residual” along the vertical axis ranging from negative 50 to 50 in increments of 25. A horizontal line is drawn at 0 on the vertical axis across the graph. Dots are scattered on the either side of the line across the graph and between negative 30 and 35 on the vertical axis. A dot is shown before 20 on the horizontal axis between negative 70 on the vertical axis.
Explain how the residual plot shows that the Linear condition for performing inference about the slope is, or is not, met.

The variability of the residuals in the vertical direction is roughly the same from the smallest to the largest -value, which suggests that the relationship between mean SAT score and percent taking is not linear.

There is clear curvature in the residual plot, which confirms that the relationship between mean SAT score and percent taking is linear.

identify an equation in point slope form for the line perpendicular to y=-2x+8 that passes through (-3,9)

Answers

Answer:

y - 9 = 1/2(x + 3)

Step-by-step explanation:

find the slope that is perpendicular to line y = -2x + 8, which is the negative reciprocal slope: 1/2

substitute the new slope 1/2 and the given/known point (-3, 9) into the point-slope form:

=> y - 9 = 1/2(x - (-3)) => y - 9 = 1/2(x + 3)

Consider the line - 5x – 3y = 7.
(a) What is the slope of a line parallel to this line?
(b) What is the slope of a line perpendicular to this line?

Answers

Answer:

a: m=5/3

b: m=-3/5

Step-by-step explanation:

first, before answering the questions, let's change the line from standard form (ax+by=c), where a and b are free coefficients into slope-intercept form (y=mx+b), where m is the slope and b is the y intercept

subtract 5x from both sides

-3y=-5x+7

divide by -3

y=5/3x-7/3

now to answer part a:

parallel lines have the same slopes, but different y intercepts.

the slope of the given line is 5/3, so therefore, a parallel line to the line y=5/3x-7/3 will also be 5/3

part b:

perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1

so to find the slope of a perpendicular line, use this formula:

5/3m=-1

multiply by 3/5 to isolate the variable

m=-3/5

therefore the slope of a perpendicular line will be -3/5

hope this helps!

Please help me on this for my quiz: Which equation represents an inverse variation with a constant of 56?

Answer:

D) xy/2 = 28

Step-by-step explanation:

Inverse Variation:

y = k/x
