Answer:

The answer is 8 quarters, 16 nickles, and 32 dimes

Step-by-step explanation:

First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.)
Then we slowly start to solve: 10/4d + 10d + 25/4d = 600
10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d)
75d= 600 x 4
d=600 x 4/75 (same here put everything over 75)
d=32
So then n= 2 x 32/4 = 16
Then n would be equal to : 1/4d= 1/4 x 32 = 8
So your answer would be 8 quarters, 16 nickles, and 32 dimes.

Hope this helped :)

In such cases binomial distribution is beneficial to use.

Binomial Distribution is simply the probability of failure or success in an experiment that is repeated multiple times.

for binomial to be used following three conditions are to be used:

What is the factorization of the expression below?

olchik [2.2K]

Answer: D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

$x^{2}-12x+36$ (1)

First term: $x^{2}$

Third term: $36=6^{2}$

If we factorize this expression we have:

$(x-6)(x-6)=x^{2}-6x-6x+36=x^{2}-12x+36$

As we can see, the trinomial (1) has two factors:

$(x-6)$ and $(x-6)$

Therefore, the correct option is D.
