Answer:

Step-by-step explanation:

Total number of marbles = 5 + 2 + 3 = 10

Probability of choosing 1 green marble = 2/10

Probability of choosing 1 yellow marble = 3/10

Notice (and this is important) that the denominator didn't change. Why?

Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.

So what is the probability of P(green then yellow)?

P(green then yellow) = 3/10 * 2/10 = 6/100

Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

Evaluate Combination (6,6)
andrew11 [14]

Answer:

nCx = \frac{n!}{x! (n-x)!}

On this case n =6 and x =6 we got:

6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1

Step-by-step explanation:

The utility for the combination formula is in order to find the number of ways to order a set of elements

For this case we want to find the following expression:

6C6

And the general formula for combination is given by:

nCx = \frac{n!}{x! (n-x)!}

On this case n =6 and x =6 we got:

6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1

Find the fifth term in the sequence that is defined as follows:
hram777 [196]

Answer : The fifth term in the sequence is -2.

Step-by-step explanation :

As we are given that the expression to calculate the n^{th} term.

The expression is as follows:

a_n=2(-1)^n

where,

n is the number of term

Given:

n = 5

Now putting the value of n in the above expression, we get:

a_n=2(-1)^n

a_5=2(-1)^5

a_5=2\times (-1)

a_5=-2

Therefore, the fifth term in the sequence is -2.

Last week Lisa had gross earning of $441.30. Cathy receives a base salary of $375 and a commision on sales exceeding her quota o
vova2212 [387]

Answer:

4.25%

Step-by-step explanation:

<u>Step 1: Calculate the commission paid</u>

<em>Commission = Gross earning - base salary</em>

<em>Commission = 441.3 - 375</em>

Commission = 66.3

<u>Step 2: Calculate the commission sales</u>

<em>Commission sales = Total sales - quota sales</em>

<em>Commission sales = 6560 - 5000</em>

Commission sales = 1560

<u>Step 3: Calculate the rate of commission</u>

<em>x% of 1560 = 66.3</em>

<em>x% * 1560 = 66.3</em>

<em>x% = 0.0425</em>

x = 4.25%

Therefore, the rate of commission was 4.25%.
