According to the given expected value, it is found that Marcos' statement is correct.
-
The interpretation of the <em>expected value</em> is that <u>over a large number of trials, the average value will be close to the expected value</u>.
In this problem:
- The expected value is of $25.
- Hence, if many of the plans are sold, the average profit per plan will be of $25, and Marcos' statement is correct.
About Amaya's statement, among groups of 1,000 customers there can be variations, hence, she is incorrect.

Answer:
96 = 3 * 32, and 32 = 16 + 16, so we can say:
96 = 3(16 + 16)
96 is also equal to 2 * 48, and 48 equals 36 + 12, so we can also say:
96 = 2(36 + 12)
If you want to go with the ridiculous, you have an infinite number of combinations you could do like that. For example:
96 = 0.15(1423987123497 - 1423987122857)
9514 1404 393
Answer:
- wrong: -2x² -x² ⇒ -2x²
- correct: x³ -3x² +6
Step-by-step explanation:
The point of these "what was done wrong" exercises is to see if you know what the correct steps look like.
On line 2, Danielle correctly distributed the minus sign to eliminate the second set of parentheses. (There is often a problem with minus signs and parentheses, so it is nice to see it done correctly.)
On line 3, the two x² terms are incorrectly combined. It looks as though Danielle simply dropped the -x² term because it disappeared without changing the coefficient of x² from -2x². The correct sum of those terms is ...
-2x² -x² = -3x²
so the correct work on line 3 is ...
x³ -3x² +6
56543 or if say y plus x or back
You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor
. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
