SOVA2 [1]
First you have to make the assumption that these are the only two outcomes. There is also the possibility of hitting the ball and getting out. 

However, if we assume that these are the only two cases, we know that the probability is 58.3%. This is because it has been on base 7 times out of 12.

Answer:

Step-by-step explanation:

first we are told that side and ae and a f are the same

so that means one side of each triangle is the same

next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles

and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle

therefore since two sides are the same length then all 3 must be the same lengths

and b/c all three are the same these two triangles are the same .. congruent

Question 5
Darina [25.2K]

Answer:

the answer is 12.24 .

Step-by-step explanation:

that answer is right is because when you add of those you get 530 , then you divide by how many numbers there are which is 7 , which equals to 75.7 . when you get that number ( 75.7) you subtract that number to 65,90,85,70,70,95, and 55 . when you get the total of all of those you add those . which is 10.7, 14.3 , 9.3 , 5.7 , 5.7 , 19.3 , and 20.7 . from adding those you get 85.7. you divide by 7 and get 12.24 . hope this helps :) .
