Step-by-step explanation:

We are dealing with theoretical probability. This means that our probability of said outcome is

\frac{x}{y}

where x is the outcome we want, and y is the total number of outcomes possible.

28. There is 3 triangles out of 6 polygons so the probability is 1/2.

29.There is 1 Pentagon so the probability is 1/6.

30. This is a complement to question 28. A complement is the inverse of the problem. A complement and its original add to 1 so the probability of both getting a triangle is 1/2.

31. There is 4 non quadraletrial so the probability is 2/3.

32. There is 3 figures that has more sides than three so 1/2 is the probability.

33.There is only multi right angles figures so 1/2 is the probability.

34. There is 30 days in April so the probability it's the 29th is

\frac{1}{30}

35. There is 31 days in July and 15 days after the 16th. So the probability

is

\frac{15}{31}

Let f(x)=x2−3x−4 . What is the average rate of change from x = 7 to x = 10? Question 6 options: 24 14 66 42
Fed [463]
Just find the slope between the points

basically find (f(10)-f(7))/(10-7)

f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66

slope=(66-24)/(10-7)=42/3=14
average rate of change is 14

Which would be a good estimate for the tax on $97.95 if the tax is 9.5%?$12$10.50$10$8.50
mamaluj [8]
First you need to turn 9.5% into a decimal so you need to move the dot " . " over to the left two times 9.5 ---> .95 ---> .095
Now that you turned the % into a decimal all thats left to do is multiply .095 by $97.95
$97.95 * .095= $9.30525 or $9.31
So the tax is $91.31
