16x + 27<br> 14x – 45<br> 25x

Very much need some help ASAP !!

Rudiy27

Answer:

D

Step-by-step explanation:

It cannot be Option A because the values are halve and there is nothing to distribute to them to make the values equal.

It's not option C because if you distribute 2y to each term in the parenthesis

you get -4 $y^{5}$ + 6y³ + 4y². But where is the 8y² and -2y?

While Option B is equivalent, you can factor it out more and find the common factor of -2 to distribute among them as shown in option D

It is option D because distributing the -2y to each term solves to

-4 $y^{5}$ + 6y³ + 8y² -2y.

-9+100 divided by 4•3

loris [4]

You would divide 100 by 4 first because according to PEMDAS (If you learned it already), you would have to go from left to right, and multiplication/division comes before addition/subtraction--so you do that math first--and you would get 25. Then you would do the multiplication because, like I said from before, Multiplication/division comes before addition/subtraction, so you then multiply 25 by 3 to get 75. After this, you do the math from the left to the right, and adding -9 to 75 is the same as 75 minus 9, so you would get 66, and that is your answer.

The phone lines to an airline reservation system are occupied 45% of the time. Assume that the events that the lines are occupie

dimaraw [331]

Answer:

0.1569 = 15.69%

Step-by-step explanation:

If eight calls were placed, and we need to know the probability of exactly two calls were occupied, we need to calculate a combination of 8 choose 2 (all the combinations of 2 occupied calls in the 8 total calls), and multiply by the probability of each case in the 8 calls (2 cases occupied and 6 cases not occupied):

P(8,2) = C(8,2) * p(occupied)^2 * p(not_occupied)^6

P(8,2) = (8*7/2) * (0.45)^2 * (0.55)^6

P(8,2) = 28 * 0.2025 * 0.02768 = 0.1569 = 15.69%
