Mean = 72
First round = 72-3 = 69
Second round = 72-1 = 71
Third round = 76
Explanation:
Total score = 72*3 = 216
69+71+x = 216
140+x = 216
x = 76
Answer:
You should use a calculator my friend.
Answer:
One-third
Step-by-step explanation:
we know that
The probability that a point chosen at random in the triangle is also in the blue square is equal to divide the area of the square by the area of triangle
step 1
Determine the area of triangle
step 2
Determine the area of the square
step 3
Determine the probability
simplify
therefore
One-third
Answer:
The answer is correct x =6.8, if she made an error, it might have been the steps she took.
Step-by-step explanation:
5.4 + x = 12.2
subtract 5.4 from both sides to put x terms on the left hand side, numerical number terms on the right hand side
5.4 - 5.4 + x = 12.2 - 5.4
x = 6.8
5 teachers and 10 tutors because we can make a proportion:
3/75=x/120, and when you cross multiply and solve for x you will get 4.8, but there can't be 4.8 teachers so we can say 5 teachers (round). Do the same for tutors: 6/72=x/120, x would equal 10.
Hope this helps!
