Which of the following is a common denominator of 1/4 and 5/6? Answers:

Mathematics
1 answer:
kondaur [170]3 years ago
5 0

Answer:

C, 12

Step-by-step explanation:

least common multiple of 4 and 6 is:

prime factorization of 4: 2*2

prime factorization of 6: 3*2

common factors: 2, so you should only multiply one of the common 2s when multiplying the factors to get the least common multiple

2*2*3=12

12 is a common denominator of 1/4 and 5/6

There are 11 books on a shelf. 5 of these books are new. (a) What is the ratio of new books to used books? (b) What is the ratio
ser-zykov [4K]
A) 
Since 5 of the books are new, that means that the other books are used. So, there are 11-5=6. The ratio would be 5:6.

b) 
The ratio is 6:11. You get the 6 from the above problem.

A group of people were asked if they had run a red light in the last year. 290 responded "yes", and 177 responded "no". Find the
GuDViN [60]

Answer:

0.621

Step-by-step explanation:

Number of people that have run a red light in the last year = 290

Number of people that have not run a red light in the last year = 177

Total number of respondents = 290 + 177

                                                 = 467

Pr(if a person is chosen at random, they have run a red light in the last year) = \frac{number of people who has run the red light last year}{total number of respondents}

                   = \frac{290}{467}

                   = 0.621

The probability that if a person is chosen at random, they have run a red light in the last year is 0.621.

What is 2^0 evaluated?
emmainna [20.7K]
2^0 is 1. The reason for this because zero is indeterminate (like how 0 * 0 is). In fact, any number to the power of 0 is 1 because of this. 

Hope this helps!

Enter the number of complex zeros for the polynomial function in the box.
Finger [1]

Given polynomial function:

f(x)=x^3-96x^2+400.

We need to apply Descartes' rule of sign to identify the number of complex roots.

The given polynomial is f(x)=x^3-96x^2+400

Let us see the number of sign changes in f(x)

There are 2 sign changes in f(x). One from plus to minus and second from plus to minus. Hence, there 2 or 0 positive roots.

Now, let us see the number of sign changes in f(-x)

f(-x)=-x^3-96x^2+400

There are only one sign change. Hence, there will be 1 negative roots.

The degree of the polynomial is 3.

Hence, there will be exactly 3 zeros.

<em>Therefore, the possible numbers of zeros are:</em>

<em>2 positive, 1 negative and 0 complex</em>

<em>0 positive, 1 negative and 2 complex.</em>

Let us see the graph:

In the graph, we can see that the graph cuts the x axis at three points (2 positive, 1 negative points).

<h3>Hence, the number of complex zeros for the given polynomial is zero.</h3>
