What is the factorization or the trinomial below? -2x^3+2x^2+12x

katen-ka-za [31]

The answer is C because the 2x outside of the brackers must be negative to produce the beginning term. The next terms are positive and two negatives make a positive, therefore we can conclude that there must be a negative inside the brackets too.

Express 30 minutes as a percentage of 3 hours 20 minutes

liberstina [14]

Answer:

15%

Step-by-step explanation:

The quantities must be in the same units

Using the conversion

I hour = 60 minutes, then

3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.

Thus

$\frac{30}{200}$ × 100% = $\frac{30}{2}$ = 15%

A fair die is rolled in a board game to determine how many spaces a player can move on their turn. It has one of the numbers 1,2

Jet001 [13]

Answer:

(a)6 (b)3 (c)0.5

Step-by-step explanation:

Given a fair die with the numbers 1,2,3,4,5, or 6 on each of its faces.

Event A is the event of rolling an even number

Event B is the event of rolling an odd number.

(a)The sample space for the outcomes in this experiment is {1,2,3,4,5,6}

There are 6 outcomes in the sample space.

n(S)=6

(b)

Event A is the event of rolling an even number

Sample space of A = {2,4,6}

There are 3 outcomes in event A.

n(A)=3

(c)The probability of event A

$P(A)=\dfrac{n(A)}{n(S)} =\dfrac{3}{6} =0.5$

P(A) =0.5 is the probability that you choose an even number.
