The scatter plot below shows the relationship between the age of a house and the number of days it takes for the house to be sold after being listed for sale.
The equation y = 0.95x + 17.56 describes the line of best fit for the scatter plot. Based on the equation, which value is most likely the number of days it takes for a 60-year-old house to be sold after being listed for sale?
A. 45
B. 70
C. 75
D. 83

Answers

Answer 1

Put 60 as x and get no of days .

y=0.95x+17.56y=0.95(60)+17.56y=57+17.56y=74.56y=75days

Option C

Answer 2

Answer:

C. 75

Step-by-step explanation:

The scatter plot shows a positive correlation since the y-value increases as the x-value increases.

Given equation of the line of best fit:

y = 0.95x + 17.56

To estimate the number of days it takes for a 60-year-old house to be sold, input x = 60 into the given equation:

⇒ y = 0.95(60) + 17.56

⇒ y = 57 + 17.56

⇒ y = 74.56

⇒ y = 75 (nearest whole day)

Therefore, according to the line of best fit, an estimate of the number of days it will take for a 60-year-old house to be sold is 75 days.

Extrapolation

For this problem, we have used the line of best fit (regression line) to predict a value of that is outside the range of the original data. When using values of x outside the range to predict corresponding values of y, this is called extrapolation. These predictions can be unreliable because there is no evidence that the relationship described by the regression line is true for all values of x. Therefore, caution should be applied in these cases.

Exact form: 17/12
Decimal form: 1.416
Mixed number: 1 5/12

Answer:

1[tex]\frac{5}{12}[/tex]

Step-by-step explanation:

As we can see, the mixed numbers have different denominators. Our goal is to get them to have the same bottom number so we can subtract them.What is the smallest number that both 4 and 3 goes into? (psst! 4 • 3)12 is the correct answer! Now we multiply [tex]\frac{3}{4}[/tex] by 3 on the top and bottom, and [tex]\frac{1}{3}[/tex] by 4 on the top and bottom.Now we have 2[tex]\frac{9}{12}[/tex] - 1[tex]\frac{4}{12}[/tex].When you subtract, don't subtract the bottom!2 - 1 = 1 and 9 - 4 = 5, so now we have 1[tex]\frac{5}{12}[/tex].

A keyboarding instructor at a community college collected data comparing a student's age and their typing speed. The equation for the line of best fit is given at y = -1.4x + 117.8, where x is the "age in years" and y is the "typing speed."

If you are 25 years of age. what is your typing speed?
A-153 words per minute
B-83 words per minute
C-63 words per minute
D-102 words per minute

HELP THIS IS TIMED!!!!

Answers

in answer:

The answer would be B

Step-by-step explanation:

Going off the y=mx+b equation, you would multiply -1.4 by 25 then add 117.8 to that result. The total of your equation would result in 82.8 words per minute.

{30 POINTS!} HELP! Two communications companies offer calling plans. With Company X, it costs 35¢ to connect and then 5¢ for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X charges, in cents, for n minutes
(35+5n)−(20+4n)

Answers

Answer:

(20 + n)¢

Step-by-step explanation:

With Company X, it costs 35¢ to connect and then 5¢ for each minute.

So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢

Again, With Company Y, it costs 15¢ to connect and then 4¢ for each minute.

So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.

Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

correct answer- (20+n) cent sign

Jasmine picked 2/5 of a bucket of strawberries. Her friend picked 3/4 of the amount Jasmine picked. How much
of a bucket of strawberries did Jasmine's friend pick?

Answers

Answer:

If Jasmine picked 4/10 (which is equivalent to 2/5) then that would mean Jasmine's friend picked 3/10.

If Jasmine picked 4 berries out of 10, that means Jasmines friend picked 3 berries out of ten.

Step-by-step explanation:

2/5 x 4 = 8/20

8/20 x 5 = 40/100

three quarters of 40/100 is 30/100

if you divide 3/4 from 2/5, you get 8/15
