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...

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.

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
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
