Hey can you please help me posted picture of question
Sergeeva-Olga [200]
Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = \frac{4}{10}= \frac{2}{5}

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = \frac{3}{9}= \frac{1}{3}

Thus, the probability of picking two white chips will be = \frac{2}{5}* \frac{1}{3}= \frac{2}{15}

Therefore, option B gives the correct answer.

Hi please help with a few (mean, median) math questions!
sattari [20]
1.rearrange your data from least to greatest:
<span>0,0,1,1,2,2,2,14 </span>

middle is 1 and 2 ... so median is 1+2/2= 1.5 and  it is the  median not the mean
2.I believe the only outlier is 50. Finding the mean would be 80.11.
<span>The answer would be D
</span>3.D. Mean always goes toward the skewness due to outliers.
<span>Median is minimally affected by outliers.
4.</span><span>We remove an outlier because we can simply assume that there was some type of extreme experimental error, or something went wrong. The mean shouldn't be effected that much, but the median will be greatly effected.</span>

Solve the system of equations<br> -5x+13y+-7<br> 5x+4y=24<br> y=<br> x=
aleksklad [387]
<h3>The value of y is equal to 1.</h3><h3>The value of x is equal to 4.</h3>

Because both equations have a term that will cancel out if they're added together, we're going to add both equations together.

-5x + 5x = 0

13y + 4y = 17y

-7 + 24 = 17

17y = 17

Divide both sides by 17.

y = 1

Now that we have a constant value of y, we can solve for x.

-5x + 13(1) = -7

-5x + 13 = -7

Subtract 13 from both sides.

-5x = -20

Divide both sides by -5.

x = 4
