Consider the experiment of selecting a card from an ordinary deck of 52 playing cards and determine the probability of the stated event. A face card or a 5 is drawn. So there are 12 face cards. Plus 5. So that is 13 options out of 52?

**Math**

I don't see any drawbacks

**Math**

Roughly speaking, the standard deviation indicates how far, on average, the observations are from the mean. Do you think that for the data set below the standard deviation will give a good indication of the typical deviation from the mean? 2, 3, 4, 4, 5, 5, 6, 6, 100 What draw...

This would be slope equalls rise over run? would it be 1/16?

**Math, please check answer**

Find the slope of the line through the given points. ( 8, -2) and ( 8, -1) Since 8-8 is 0 would the slope be 0 or would there be no slope?

okay, I understand now. Thank you. This is so confusing to me.

**Math**

x 5 10 15 20 25 30 y 50 60 70 80 80 90 Is this not linear?

**Math, please check work**

Thanks so much!

**Math, please check work**

find the other endpoint of a line segment with the given midpoint and one endpoint. Endpoint: (0,0) midpoint: (4, -3) I would Double the midpoint and add on the endpoint The other endpoint would be (8, -6) is this correct?

**Math**

Thank you.

**Math**

how would I find the slope of the line passing through each pair of points in (3, 7) and (6, -11)

**Math**

Very helpful! Thank you!

**Math**

Find the equation of a line that passes through the point (1,2) and has a slope of 1/3 Can you please show me how you found the equation.

**Math**

I would/could have done the work. I just didn't know which technique is best. The name of the technique. Thank you for your help!

**Math**

Which linear technique would be best to solve this problem? 3x/4 + 6 = -12 And which quadratic equation would be best for -4x^2=0 Thanks for any suggestions.

**Math**

I still can't quite grasp it but your explanation is very helpful. Thank you!

**Math**

For which values is the relationship linear? Tell how you decided. Write the equation for each linear relationship x 5 10 15 20 25 30 y 20 30 40 50 50 50

**Math**

Ms. Sue, do you have a suggestion?

**Math**

Which linear technique would be best to solve this problem? 3x/4 + 6 = -12

**Math**

The problem is actually y = 20 + x/3. Would it still be the same?

**Math**

Give five ordered pairs that makes the equation true y = 20 + x3

**Math**

Does anyone know how to solve this.

**Math**

For which values is the relationship linear? Tell how you decided. Write the equation for each linear relationship x 5 10 15 20 25 30 y 20 30 40 50 50 50 I don't understand what the relationship has to do with being linear?

**Math**

I thought so, just wanted to verify. Thank you

**Math**

Yes, it meant divisible by, or I am assuming so. That is how it was asked on paper. So, the answer isn't true.

**Math**

Determine whether the statement is true or false. Show or explain why. If n is a natural number and 4 | n, then 8 | n.

**Math**

Yea, that is what I am confused about as well. So is it 1 if that is the only possibility?

**Math**

Yes, the answer given was that "clearly, there is no common factor " But that isn't a possiblity. The answer is either A) 65, B)26, C) 1 or D)6
