Answer:
whats the question
Step-by-step explanation:
The set given by the project grade is {1, 2, 3, 4, 5}. If the random variable, X, is the project grade, the mean of the probability distribution is determined by:
Sum = 1 + 2 + 3 + 4 +5
= 15
Mean of the probability distribution is 15/n, where n = 5
= 15/ 5
= 3
Answer:
A
Step-by-step explanation:
write it as a ratio
11:6 = 110: x
cross multiply
11x= 660
divide by 11 on both sides
x= 60
Answer:
x=17
Step-by-step explanation:
well the triangles are congruent so that equation has to equal 61, so set it equal to 61, once you do that subtract 10 with 61 giving you 51, then divide 3 with 51 and you get 17
Answer:
60
Step-by-step explanation:
calculated it with scientific calculator
