Find the length of the midsegment.
Gala2k [10]

Answer:

57

Step-by-step explanation:

The midsegment is one half the length of the third side of the triangle, that is

6x + 3 = \frac{1}{2}(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

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 117.7-cm and a standard dev
Andre45 [30]

Answer:

Required probability is 0.9748

Step-by-step explanation:

given data

mean \mu = 117.7-cm

standard deviation \sigma = 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

Z = \dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}    

put here value with x value 118.5-cm

Z = \dfrac{118.5-117.7}{\dfrac{2.2}{\sqrt{29}}}

Z = 1.9582

p value is 0.9748

so required probability is 0.9748
