Does someone mind helping me with this problem? Thank you!
faltersainse [42]

\frac{10-(3 \cdot 2^2 - 23)}{(1 + 10^2)-2^2 \cdot 5^2} =

10-\left(3\cdot \:2^2-23\right) =10-\left(-11\right) =21

\left(1+10^2\right)-2^2\cdot \:5^2 =  101-2^2\cdot \:5^2 = 101-4\cdot \:5^2 =101-4\cdot \:25 =101-100 = 1

=\frac{21}{1}

\frac{a}{1}= a

=21

I hope I helped you!

For synthetic division:
1) Write the coefficients of the polynomial under the division symbol, in order. Make sure you include coefficients that are 0, so they may not be written out in the polynomial! 
The coefficients are 7, 1, 0 (the coefficient of x), and -4 in that order

2) The divisor is in the form of x - a. The number "a" goes outside the bracket.
a = 5

Since 7, 1, 0, -4 are under the bracket and 5 is outside the bracket, the answer is C.

------

Answer: C

Based on a​ poll, among adults who regret getting​ tattoos, ​16% say that they were too young when they got their tattoos. Assum
e-lub [12.9K]

Answer:

The problem is incomplete, but it is solved using a binomial distribution with n = 8 and p = 0.16

Step-by-step explanation:

For each adult who regret getting tattoos, there are only two possible outcomes. Either they say that they were too young, or they do not say this. The answer of an adult is independent of other adults, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

​16% say that they were too young when they got their tattoos.

This means that p = 0.16

Eight adults who regret getting tattoos are randomly​ selected

This means that n = 8

Find the indicated probability.

The binomial distribution is used, with p = 0.16, n = 8, that is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = x) = C_{8,x}.(0.16)^{x}.(0.84)^{8-x}
