Answer:

(A) The rate of change in the price of a bushel of corn in the current year is $7.

(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Step-by-step explanation:

The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.

Part A:

The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.

The formula to compute the slope is:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Consider the ordered pairs: (4, 28) and (10, 70)

Compute the slope of the line as follows:

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{70-28}{10-4}\\\\=\frac{42}{6}\\\\=7$

Thus, the rate of change in the price of a bushel of corn in the current year is $7.

Part B:

The data for the price of bushels in the previous year is as follows:

Number of Bushels Price

2 10

4 20

6 30

8 40

Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:

Consider the ordered pairs: (2, 10) and (6, 30)

$\text{Slope}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\frac{30-10}{6-2}\\\\=\frac{20}{4}\\\\=5$

The rate of change in the price of a bushel of corn in the previous year is $5.

Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

A map of a bike race has a scale of 2 inches=50 miles. The distance to the 1st aid station from the starting line is about 1.25"

svp [43]

2 inches = 50 miles
1 inch = 25miles
0.5 inches = 12.5 miles
0.25 inches = 6.25
you need 1.25 so you do 25+ 6.25 and get 31.25. To the nearest mile this would be 31 miles.

Slope -2/3, through (-1,-6) <br><br> What is the equation of the line?

Arturiano [62]

Answer:

Step-by-step explanation:

y + 6 = -2/3(x + 1)

y + 6= -2/3x - 2/3

y + 18/3 = -2/3x - 2/3

y = -2/3x - 20/3

Yuri surveyed a random sample of 75 students in his school about their favorite color. Of the students surveyed, 49 chose lavend

anastassius [24]

Answer:

600

Step-by-step explanation:

Take the number that answered lavender and divide by total # of students surveyed

49/75 = .653333 or 65.3%

then take the total # of students and multiply by .6533333

908x .6533333 = 593.22

so the closest estimate is 600
