Answer:
57
Step-by-step explanation:
The midsegment is one half the length of the third side of the triangle, that is
6x + 3 =
(3x + 87)
Multiply both sides by 2 to clear the fraction
12x + 6 = 3x + 87 ( subtract 3x from both sides )
9x + 6 = 87 ( subtract 6 from both sides )
9x = 81 ( divide both sides by 9 )
x = 9
Thus
midsegment = 6x + 3 = 6(9) + 3 = 54 + 3 = 57

Answer:
Required probability is 0.9748
Step-by-step explanation:
given data
mean
= 117.7-cm
standard deviation
= 2.2-cm
sample size n = 29
solution
we consider here random variable which represents here length of rod= x
so get here first z that is express as
put here value with x value 118.5-cm

Z = 1.9582
p value is 0.9748
so required probability is 0.9748
Answer:
3.5
Step-by-step explanation:
Because if .5 turns into one whole if you add .5 then its a half and so when you put the .5 into a fraction so thats the answer.
