Mathematics
1 answer:
Effectus [21]3 years ago
6 0

Answer:

I agree with Noah's Method because following PEMDAS you have to do exponents first. 10^3 is 1000 and then you can add the 20. Jada's method is incorrect because you cannot add the two together.

Choose the correct simplification of (6x-5)(2x^2-3x-6)
bogdanovich [222]

Answer:

12x^3 -28x^2 -21x +30

Step-by-step explanation:

1) Distribute!

(6x-5)(2x^2-3x-6) = 12x^3 -18x^2 - 36x -10x^2 +15x+30

2) Combine like terms!

12x^3 -18x^2 - 36x -10x^2 +15x+30 = 12x^3 -28x^2 -21x +30

Answer is:

12x^3 -28x^2 -21x +30

Jaquelyn wants to start getting to school on time more often. She is looking at some of her habits.
olganol [36]

Given that Jaquelyn was tardy on Monday, there is a 12 percent chance she will be late on Tuesday as well.

What is the Probability?

How likely it is that a stated event would occur is assessed using probability. The event would have a probability of 1 if it happened with certainty. The probability of an occurrence would be zero if it were absolutely guaranteed that it would not occur.

As getting late on Monday and Tuesday are independent events, their probabilities can be multiplied.

So the probability of getting late on Tuesday, given she was late to school on Monday = Probability of being late on Monday x Probability of she being late on Monday and she is late on Tuesday 60% of the time.

= 0.2 x 0.6

= 0.12

Thus the approximate probability that Jaquelyn will be late on Tuesday, given she was late to school on Monday will be  0.12

KiRa [710]

Answer:

The horizontal axis in the coordinate plane is called the x-axis. The vertical axis is called the y-axis. The point at which the two axes intersect is called the origin. The origin is at 0 on the x-axis and 0 on the y-axis.
