1 answer:
Burka [1]1 year ago
6 0

The answers are

1. 1

2. \frac{5}{8}

3. \frac{19}{5}

What are fractions?

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. In ordinary English, a fraction refers to the number of parts of a specific size.

We are given,

1. \frac{4}{7} + \frac{3}{7}

As the denominator of both fractions are same we add the numerator

We get,

\frac{7}{7}=1

2. \frac{7}{8}-\frac{2}{8}

As the denominator of both the fractions are same we subtract the value in the numerator we get,

\frac{7}{8}-\frac{2}{8}=\frac{5}{8}

3. 6\frac{4}{5}-3

We first simplify the first term of the equation,

6\frac{4}{5}=\frac{34}{5}

Now as the denominator is not same we use cross multiplication to perform the operation

\frac{34}{5}-3=\frac{34-15}{5}

On further simplifying we get,

\frac{34-15}{5}=\frac{19}{5}

Hence the answers are

1. 1

2. \frac{5}{8}

3. \frac{19}{5}

Which of the following are the zeros of the function y= 3(x-a)(x+b) in terms of a and b? ​
frosja888 [35]

The correct answer is option 2.

3 = 0

x - a = 0

x = a

x + b = 0

x = -b

We do not multiply any of these values by 3 because in a way, 3 is acting as another "zero" of the equation. Though, as shown above, it does not equal 0, it still does not apply to any of the other equations solved above.

Hope this helps!! :)

If A and B are independent events with P( A) = 0.60 and P( A| B) = 0.60, then P( B) is: a. 0.60 b. cannot be determined with the
Simora [160]

Answer:

<h2>B. cannot be determined</h2>

Step-by-step explanation:

For two events A and B to be independent, it means they can occur at the same time i.e the occurrence of one does not affect the other occurring. It is represented as P(A∩B) = P(A)P(B)

Given P( A) = 0.60 and P( A| B) = 0.60, to find P(B), we will use the formula for the conditional probability P( A| B) = P(A∩B) /P(B)

P( A| B) = P(A)P(B) /P(B)

P( A| B) = P(A)

Since  P( A| B) = 0.60, therefore P(A) is also equal to 0.60 and P(B) cannot be determined since they cancelled out already
