Answer by JKismyhusbandbae: 26d - 24

How to get Answer: \mathrm{Expand}\:2\left(d-6\right):\quad 2d-12\\=2d-12-4\left(-6d+3\right)\\\mathrm{Expand}\:-4\left(-6d+3\right):\quad 24d-12\\=2d-12+24d-12\\\mathrm{Simplify}\:2d-12+24d-12:\quad 26d-24\\=26d-24

Explanation: Use the distributive property to remove both sets of parentheses. Then combine like terms (terms involving the variable d and constant terms) to simplify the expression.

I'm assuming you want us to simplify this

remember the distributive property

a(b+c)=ab+ac



2(d-6)-4(-6d+3)


2(d-6)=2(d)+2(-6)=2d-12

-4(-6d+3)=(-4)(-6d)+(-4)(3)=24d-12


2(d-6)-4(-6d+3)=2d-12+24d-12=26d-24

The probability that an American CEO can transact business in a foreign language is .20. Twelve American CEOs are chosen at rand
NNADVOKAT [17]

Answer with Step-by-step explanation:

We are given that

The probability that an American CEO can transact business in  foreign language=0.20

The probability than an American CEO can not transact business in foreign language=1-0.20=0.80

Total number of American CEOs  chosen=12

a. The probability that none can transact business in a foreign language=12C_0(0.20)^0(0.80)^{12}

Using binomial theorem nC_r(1-p)^{n-r}p^r

The probability that none can transact business in a foreign language=\frac{12!}{0!(12-0)!}(0.8)^{12}=(0.8)^{12}

b.The probability that at least two can transact business in a foreign language=1-P(x=0)-p(x=1)=1-((0.8)^{12}+12C_1(0.8)^{11}(0.2))=1-((0.8)^{12}+12(0.8)^{11}}(0.2))

c.The probability that all 12 can transact business in a foreign language=12C_{12}(0.8)^0(0.2)^{12}

The probability that all 12 can transact business in a foreign language=\frac{12!}{12!}(0.2)^{12}=(0.2)^{12}

A bag has 3 red marbles, 2 blue, 4 greens and 1 yellow. What is the probability of pulling a blue, putting it back
Tomtit [17]

Answer: 2/25

Step-by-step explanation: Since we are replacing the marbles, these two events are independent which means that the outcome of the first does not affect the outcome of the second.

First find the probability of selecting a blue marble.

There are 2 favorable outcomes, the blue marbles,

and 10 possible outcomes, all the marbles in the bag.

So the probability of selecting a blue marble is 2/10 or 1/5.

<em>Always reduce when finding probability</em>

<em></em>

Now we find the probability of selecting a green marble.

There are 4 green marbles and 10 total so the probability of

selecting a green marble is 4/10 or 2/5.

Now we multiply the probabilities.

So we have 1/5 x 2/5 or 2/25.
