Which of the following is an example of theoretical probability? a. wendy flipped a coin 5 times, and the results were 4 tails. the probability of tails is 4/5 . b. kenny rolled a number cube 9 times and got 4 even numbers. the probability of an even number is 4/9 . c. there are 52 playing cards in a deck, and 4 of them are aces. the probability of turning over an ace is 4/25 . d. there were 73 people in a grocery store, and 45 of them bought milk. the probability of people buying milk is 45/73 .

I think D is the answer...

A. is the answer :) yw btw

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
