Answer:

  D.  y = -0.32x² -1.26x +15.81

Step-by-step explanation:

This is one of those multiple-choice questions where you only need a vague idea of what the answer is supposed to look like.

In this case the answer must be a quadratic equation with a negative leading coefficient. (The parabola opens downward.)

The only answer choice that is a 2nd degree polynomial with a negative leading coefficient is choice D.

__

A: linear equation

B: exponential equation

C: quadratic that opens upward (positive leading coefficient)

D: quadratic that opens downward -- the answer you're looking for

In a game of chance, the probability of winning a $50 is 40% and the probability of losing a $50 prize is 60%. what is the expec
melamori03 [73]
To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10

Consider the numbers 14.25 and 0.86.
klio [65]

Answer:

Part A

The given numbers are 14.25 and 0.86

By multiplying the two numbers, we have;

14.25 × 0.86 = 12.255

By adding the two numbers, we have;

14.25 + 0.86 = 15.11

Therefore, addition gives the greatest solution because one of the number is a fraction less than one

Part B

By dividing the two numbers (Dividing the larger number, 14.25 by the smaller number 0.86), we have 14.25/0.86 ≈ 16.57

Therefore, dividing the larger number by the smaller fraction gives a solution larger than the solution found in part A because the larger number multiplied by (1 - the inverse smaller fraction number) is larger than the value of the smaller (fraction) number
