Answer: The functions are both increasing.

The function for plan II has a greater unit rate.

The function for plan I has a greater y-intercept.

Step-by-step explanation:

According to the given question we have two functions.

Function 1. $y=12,000+400x$

Function 2. $y=11,000+420x$

Both are written in intercept form of linear equation $y=mx+c$ , where m is the slope of line or rate of change of y w.r.t. x.

Slope of function 1. = 400

i.e. Unit rate = $400 per month

Slope of function 2. = 420

i.e. Unit rate = $420 per month

⇒The function for plan II has a greater unit rate.

As both has positive slopes.

∴ Both functions are increasing functions.

For y intercept , put x=0 in the functions.

The y-intercept of function 1 = $12000

The y-intercept of function 2= $11000

⇒The function for plan I has a greater y-intercept.

A baseball collector took inventory of all of his baseball cards along with the value of each card. The box plot represents the

love history [14]

Answer: less than 25%

Step-by-step explanation:

The box plot can be read as follows:

The first black dot is the minimum value.

The first half of the rectangle is the lower quartile.

The line that separates the two rectangles is the median.

The second half of the rectangle is the upper quartile

The final point is the maximum.

Knowing that each quartile represents about the 25% of the elements for the set, we can see that both lower and upper quartile (and the 25% of the elements that come after the upper quartile) cost more than $45.

Then we know that at least the (25% + 25% + 25%) = 75% of the cards in the collection cost more than $45.

And we also have elements that are not in the lower quartile that cost more than $45, but we can not determine the percentage that they represent.

So we can only conclude that more than the 75% of the collection costs more than $45.

Now we want to know the percentage of the baseball cards valued at less than $45.

So if more than 75% is valued at more than $45.

Then less than 25% is valued at less than $25.

Darina [25.2K]

Answer:

40%

Step-by-step explanation:

First off, 1/5 is equal to 20%. If you're diving something into 5ths, you can do 100 / 5, which is 20. So you know that Raul scored at least 20% of the points. His friend Jake ALSO scores 20% of the teams points, making 20 + 20 = 40%. Therefore, 40% of the teams points were scored by Raul and Jake.
