A farmer fills his field proportionately with soybeans and corn. Last year he planted 200 acres of corn and 50 acres of soybeans

malfutka [58]

Answer:

Part A) Is a directly proportional

Part B) The constant of proportionality is $k=0.25$

Part C) The equation is $y=0.25x$

Part D) $62.5$ acres of soybeans

Step-by-step explanation:

Part A) Are the number of acres of corn and the number of acres of soybeans directly proportional or inversely proportional?

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$

Let

x-----> the number of acres of corn

y----> the number of acres of soybeans

$y/x=k$

if the number of acres of corn increases then the number of acres of soybeans increases

if the number of acres of corn decreases then the number of acres of soybeans decreases

therefore

The relationship is a directly proportional

Part B) What is the constant of proportionality?

we have that

For x=200, y=50

substitute

$y/x=k$

$k=50/200$

$k=0.25$

Part C) Let x equal the number of acres of corn and y equal the number of acres of soybeans. Write an equation to show this relationship.

The linear equation that represent the direct variation is equal to

$y/x=k$

we have

$k=0.25$

substitute

$y/x=0.25$

$y=0.25x$

Part D) How many acres of soybeans can the farmer plant this year if he plants 250 acres of corn?

For x=250

Find the value of y

substitute in the linear equation the value of x and solve for y

$y=0.25(250)=62.5$ -----> acres of soybeans

Which of the box plots A,B Or C show a sample that has

Paul [167]

The answer is C
This is a box plot diagram also know as a box and whisker plot as you probably see where it gets its name from, to find which diagram is correct you need to look for the following things. First we need to see if the median which in this case is 12 is in on the correct place which in C it is nicely lines up to 12 in the center of the diagram. The median for a the line in the line in the middle of the box plot.
Now we need to have a look at our lower quartile and see that it does start at 6 and the upper quartile does end at 16 these are the lines that make the rectangle shape in the centre lucky for us in C they do. Then we need to see if the lines that run horizontally through the box ( may also be called the whiskers) start at the minimum 3 and end at the maximum of 22 which they do so in the end gives C is true only diagram with all of these in.
Hope this helps !
