Answer:

The time for 22 leg-press reps is 11.9 seconds.

Step-by-step explanation:

The lines of best fit is the trend line of the dataset.

The equation of line of best fit is y = 0.120x + 9.274The time for 22 leg-press reps is 11.9 seconds(A) The equation of the line of best fit

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

(B) The number of seconds for 22 leg-press reps

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

  = 2.640 + 9.274

  = 11.914

(Approximate to the nearest hundredths)

  = 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.


Hope my answer helps you.

The like terms to 4/5 in the group 2 are given as follows:

D. -0.1.

F. 12.

What are like terms?

Like terms are terms that have the same letter and the same exponent, as thus they can be either added or subtracted to simplify expressions.

The most basic example of like terms are constants, as they can always be added or subtracted.

In group 2, the terms that are constant are the terms -0.1 and 12, hence they are like terms to the fraction 4/5, meaning that the correct options are given by options D and F.

The like terms to -2.1x would be of 3x and also x/3, as they would have the same variable x with exponent 1.

Answer: Y = 3/8

Step-by-step explanation:

You can either use the rise/run method or subtract 2 points from the line to get the slope. You can do the rise/run method by starting at a point that is on the corner of the square and keep counting how many spaces you have to go until you get to the next even point. This number will be on the bottom, then count up until you get to that even point,this amount of spaces this takes will be on top. Since there are only 2 visible points on this graph,I will use the other method. You can use either the y1-y2/x1-x2 formula or do this

8,3

0,0

8,3  
Remember,the y goes on top! Our slope is 3/8,also since the y intercept is the orgin/0,0 we don't need to add it at the end. I hope this helps and wasn't too complicated!

y =  3/8(x) is the equation that represents the proportional relationship in this graph, for y in terms of x.

What is proportional?

In mathematics, two sequences of numbers, frequently experimental data, are proportional or directly proportional if their corresponding elements have a constant ratio, known as the coefficient of proportionality or proportionality constant.

If corresponding elements in two sequences have a constant product—also known as the coefficient of proportionality—then the two sequences are inversely proportional.

This definition is frequently broadened to include associated varying amounts, also known as variables.

We can see that when y = 1.5, then x = 4

And when y = 3, x = 8

Putting the value in slope form

y - y1 = m(x - x1)

3 - 1.5 = m(8 - 4)

1.5 = m(4)

m = 1.5/4

m = 3/8

Now simply we put the value in y-intercept form

y - 3 = 3/8(x - 8)

y = 3/8(x) - 3 + 3

y =  3/8(x)

Answer:

B. y = 5x

Step-by-step explanation:

there are 2 coordinates (0,0) and (3,15)

slope m = (y2-y1)/(x2-x1)

m = (15 - 0)/(3 - 0) = 15/3 = 5

Using y = 0, x = 0, m - 5

y = mx + b

0 = 5(0) + b

b = 0

Answer:So let's start by guesstimating the slopes:

Next let's look at the solution: the two lines intersect at the point (1, -1).

**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)

A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2

B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense

C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations

D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1

the fewest number of people surveyed is 125, i’ll explain why.

the percentage of people that finished the survey is 93.6%, given.

this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.

you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.

p = 117/125.

the fraction can’t be reduced any further, so that’s your answer.
