Using the it's concept, the correct calculation for the probability of choosing a red grape and then without putting the red grape back into the bowl, choosing a green grape is:

p = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem, we have that there is a total of 6 + 10 + 8 = 24 grapes. For the first grape, 10 are red, hence the probability that the first grape is red is:

pR = \frac{10}{24} = \frac{5}[12}

For the second grape, considering that the first was red and was removed, there will be 23 grapes, out of which 6 will be green, hence the probability that the second grape is green is:

pG = \frac{6}{23}

Hence the correct expression is found as follows:

p = pR \times pG = \frac{5}{12} \times \frac{6}{23} = \frac{5}{2} \times \frac{1}{23} = \frac{5}{46}

The number:

5.634\times10^2

is going to be between the numbers 563 and 564; since 10 squared equals 100 and the decimal point will move to places to the right.

Therefore, the answer is D.

Solve for x. <br> 4x-5/y=2z
Monica [59]
So you don't know the value of x, y, or z; all you're told is to solve for x. This is not impossible (even though it may seem like it). Your answer will have several variables in it, but in algebra you won't always have the complete answer.
Start with the equation: 4x - 5 / y = 2z
The first thing you'll want to do to it is try to get x alone on one side.
4x - 5 / y = 2z
       +5       +5 --> 4x / y = 2z +5
                               *y           *y --> 4x = y (2z + 5)
                                                        /4              /4   --> x = (y (2z + 5)) / 4 
Your final answer will be: x = (y (2z +5)) / 4
Hope it makes sense to you!!
