Part A: What is the approximate y-intercept of the line of best fit and what does it represent? (5 points) Part B: Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice. Show your work and include the points used to calculate the slope

Answers

Answer:

Well I can't do it if you don not show the graph :(

Step-by-step explanation:

Answer:

Let's actually find the line of best fit...

m=(nΣyx-ΣyΣx)/(nΣx^2-ΣxΣx)

m=(11*836-130*55)/(11*385-3025)

m=2046/1210  

m=93/55

b=(Σy-93Σx/55)/n

b=(55Σy-93Σx)/(55n)

b=(7150-5115)/(55*11)

b=185/55, so the line of best fit is:

y=(93x+185)/55

A)  The approximate y-intercept (the value of y when x=0) is 185/55≈3.36.

Which means that those who do not practice at all will win about 3.36 times

B) y(13)=(93x+185)/55

y(13)≈25.34

So after 13 months of practice one would expect to win about 25.34 times.

3 feet = 1 yard
John has 476 feet of yarn and he needs to know how many yards he has. How many yards of yarn does John have. (solve and explain)

Answers

You get 158.667 yards of yarn

Explanation-You dived the length value by 3 since 3 feet = 1 yard
158.7 this is because you have to divide 476 by 3 because each 3 feet of yarn is a yard. Hope that makes sense I’m not very good at explaining.

Daniel and Edwin went to lunch. Daniel’s meal cost $20 and Edwin’s meal cost $18.50. They each left an 18% tip on the price of their own meal. How much did Daniel and Edwin pay in total?

Answers

Answer:

$45.43

Step-by-step explanation:

20 × 0.18 = 3.60

18.50 × 0.18 = 3.33

3.60 + 3.33 = 6.93

The total in tips is 6.93

20 + 18.50 = 38.50

The total meal cost is 38.50

38.50 + 6.93 = 45.43

The total of everything is 45.43

Answer:

The answer is $45.43
