Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

A quadratic equation will always start with a term being squared. For example, 8x^{2} + 5x + 7 = 44. Another example would be 4x^{2} + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!

Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

Yes, they are different. Imagine your random variable takes only the values 0 and 1, with equal probability.

Squaring your value gives 0 and 1 with equal probability;

multiplying by itself gives 0*0,0*1,1*0, and 1*1 with equal probability.

The first has an expected value of .5 the second 0.25

An unusual number cube (with 6 sides) has the numbers 2, 2, 4, 4, 6, and 6 on its faces.
Hunter-Best [27]

P(2 or 4) = 2/3

p(multiple of 2) =  1

p(multiple of 3) = 1/3

P(odd prime numbers) = 0

<h3>What are the probabilities?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

P(2 or 4) = (number of sides that have a value of 2 / total number of sides) + (number of sides that have a value of 2 / total number of sides) = 2/6 + 2/6 = 2/3

p(multiple of 2) = number of sides that are a multiple of 2 / total number of sides

6/6 = 1

p(multiple of 3) = number of sides that are a multiple of 3/ total number of sides

= 2/6 = 1/3

P(odd prime numbers) = number of odd prime numbers / total number of sides  = 0
