Zigmanuir [339]3 years ago
8 0

Answer:

B)

Step-by-step explanation:

If it's an easy quiz, there would be a lot of students with high grades, therefore, the data set would be skewed left, the mode would be in the right side of the graph, then we would have the median and the mean would be the lower value. There would be just a few students with lower grades and this grades would pull the mean away from the median toward the left.

Seven years ago, Gaetano found a box of old baseball cards in the garage. Since then, he has addeda consistent number of cards t
AURORKA [14]
Baseball cards

We know two things:

Gaetano had 52 cards on 3 years

Gaetano had 108 cards on 7 years

Then, from the fourth year to the seventh year he added

108 - 52 = 56 cards

In four years he added 56 cards. Then each year he added

56/4 = 14 cards

Since

14 * 3 = 42

On the first three years he added 42 cards to his collection.

Then he started with

52 - 42 = 10 cards

Answer: Gaetano started his collection with 10 cards and he adds 14 new cards to it each year

How do you do this?

Answer:

  see attached for 1 and 2

Step-by-step explanation:

It's almost like drawing any other graph. Here, you need to pay attention to the domain on which each piece is defined. You need to add dots where the function is discontinuous to show how the function is defined at the discontinuity.

__

1) The dividing line is at x=2.

To the left of that line, the graph is the constant function y=3.

To the right of that line, the graph is the quadratic function y = (x-3)².

The dots are placed where x=2 (at the boundary between the parts of the function). A solid dot is placed on the end of the horizontal line, since that is the function value at x=2. An open dot is placed on the end of the parabola, since the function is not defined at that point (2, 1).

The graph is shown in the first attachment.

__

2) Here, the dividing line between the pieces is at x=-4. Again, the function is constant to the left of that line. To the right of that line, it is a line with a slope of 2 and a y-intercept of 3. The treatment of dots at the ends of the curve is the same, since the function is defined at x=-4 as the left piece, not the right piece.

The graph is shown in the second attachment.
