Using the line of best fit, estimate how may miles Jack ran the 10th week; show work.During which week would you expect Jack to run a full marathon, 26.3 miles? Do you think that you should round up or down to the nearest week? Why?

Answers

Answer 1

Answer: one way is to type it into your trusty TI and use the table from presing stat and then stat againg then calc then 4
so the equation that I got from your set of points is y=1.983333333333333x+0.80555555555

Answer 2

Answer: Take two points and find the slope.
(4,9) (6,13)
y2-y1/x2-x1
4/2=2=m
y=2x+b
9=8+1
b+1
y=2x+1
Set x to 10 to find the 10th week
y=20+1
21 miles
Set y=26.3 to find which week.
26.3=2x+1
2x=25.3
x=12.6 weeks or round to 13 weeks
I think he should round up because in more slopes in between points, there is a lesser slope than 2.
Hope this helps.

how many multiple- choices questions did tanika get correct

Answers

this is a ratio based problem.
knowing that there are 20 mc questions and she got 9/10 of them right, we can solve the problem by getting the equivalent fraction that has the same denominator as the total number of mc questions ( in this case,20)

multiplying 9/10 by 2/2, we get 18/20 and that's the answer

She got 19 answers correct.

What percent of the boxes have x's in them

Answers

There are 32 total boxes. Only 14 of the boxes in the grid have an x inside of the box. We can find what percent of the boxes have an x in them by making a fraction. $(14)/(32)$ represents the number of boxes that have an x in them out of all the boxes in the grid.

$(14)/(32)$ can be reduced to $(7)/(16)$ by dividing both the numerator and denominator by the Greatest Common Factor of 14 and 32 which is 2.

7 ÷ 16 = 0.4375

0.4375 × 100 = 43.75%

Therefore, 43.75% of the boxes have an x inside of them.

It is a 4 by 8 grid. So there are 32 squares total.
Now, count how many x's are on the boxes.
I counted 14 x'ed boxes.
Divide 14 by 32
14/32=0.4375
Now convert to a percent. Move the decimal two places to the left.
You get 43.75% as the answer.
