Step-by-step Answer:
One of the properties of a least-squares regression line (line of best fit) is that the line always passes through the point (xbar, ybar).
Assuming the given "line of best fit" is a least-squares line, then we are given
a slope m=1.885 passing through (x0,y0)=(3.448,12.318).
Applying the standard point-slope formula:
(y-y0) = m (x-x0)
we get
y-12.318 = 1.885(x-3.448)
Expand and simplify,
y=1.885x -1.885*3.448 + 12.318, or
y=1.885(x) + 5.81852
(numbers to be rounded as precision dictates).
The answer that is NOT the formula for an area of a rectangle is A= 1/2X h X (Base 1 + Base 2)
Description 1: "The integer n is between -7 and -4, excluding both endpoints"
Description 2: "The integer n is larger than -7 and smaller than -4"
To solve this problem you need to do a proportion. First you do 15 over x= 75 over 100. Now you multiply 15 by 100 which is 1500. Next, you divide 1500 by 75. YOUR ANSWER IS 20 peaches. To check your work, you could divide 20 by 4 which is 5. 5 times 3= 15 peaches.
Answer:
1) 1/7
2) 1/3
3) 1/4
Step-by-step explanation:
1) Since there are 7 days in a week it can be expressed as the fraction 1/7
2) Since there are 3 feet in a yard it can be expressed as the fraction 1/3
3) Since there are 4 quarts in a gallon it can be expressed as the fraction 1/4
