1. 1-2x>13 ----> -2x>13-1  -----> -2x>12 ----> (divide both sides by -2 and switch the sign) ---> x<-6

The answer is A

Step-by-step explanation:

If x= -6, the the inequality becomes -5 - 3(-6)>10

first you do 3 times -6, which equals -18, and then you do -5 minus -18, and that gives you 13 . 13>10, so if x= -6, A becomes true.

(sorry if you didn't understand my explanation.)

Which expression is equivalent to -9(x – 4) – 6x?
kvv77 [185]
= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first

= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x

Combine like terms
= (-9x-6x) + 36

= -15x + 36

The middle choice is the answer:
-15x + 36

Hope this helps! :)

7. (05.02 MC)

Considering the Central Limit Theorem, we have that:

a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

b) The probability can be calculated, as the sample size is greater than 30.

<h3>What does the Central Limit Theorem state?</h3>

It states that the sampling distribution of sample means of size n is approximately normal has standard deviation s = \frac{\sigma}{\sqrt{n}}, as long as the underlying distribution is normal or the sample size is greater than 30.

In this problem, the underlying distribution is skewed right, that is, not normal, hence:

  • For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.
  • For item b, the probability can be calculated, as the sample size is greater than 30.

We will not regroup this ones place because the sum of the digits in the ones place is not up to. It's just 6+1+2 = 9.

Therefore, 13a) No.

There is no regrouped tens to add, so we would not able to regroup the ones place.

Therefore, 13b) No.

We regroup the tens place because the sum of the digits in the ones place is upto to 10.

And 13c) Yes.

We add the regrouped hundred as we regrouped the ones place.

Therefore,

13 D) Yes.
