Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults.  A population, in this context, is the group being researched.

D isn't the correct answer; the fact that adults are the target population doesn't validify anything.

C doesn't entirely prove its point because there are other factors that go into the game being biased.  In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams.  Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.

A would be my answer for reasons stated above.

Which graph shows a line with the same y intercept as the graph of 10x - 16y = 40
Amanda [17]

Answer:

The graph option where the y-axis is intercepted at y = -2.5 by the line of the graph.

Step-by-step explanation:

The answer choices for the possible graphs that have the same y-intercept as the graph of 10x - 16y = 40 is missing here.

However, the answer can still be explained here.

We can figure out how the graph would look like.

First, understand that the y-intercept of a graph is the value of y, of the point where the line intercepts the y-axis.

Let's figure out what the y-intercept is given a graph represented by the equation, 10x - 16y = 40.

Rewrite the equation in slope-intercept form.

10x - 16y = 40

-16y = -10x + 40

y = -10x/-16 + 40/-16

y = ⅝x - ⁵/2

Therefore, the y-intercept of the graph of 10x - 16y = 40 is -⁵/2 or -2.5.

✅The graph shows a line with the same y-intercept as the graph of 10x - 16y = 40, would have it's y-axis intercepted at y = -2.5.

A person died leaving property worth Rs 4000.40. His widow got 0.125 of the property. His son got 0.4 of the remainder. What did
MakcuM [25]

Answer:

$2100.21

Step-by-step explanation:

If the widow gets 0.125 and the son gets 0.4, together they get 0.525, or 52.5%. If you multiply 4000.4 * 0.525, you get 2100.21, which is a little over half of 4000.
