The true statement is Line MK is the perpendicular bisector of LN and ML is ≅ MN.
<h3>What is perpendicular?</h3>
Perpendicular lines are lines that intersect at a right (90 degrees) angle.
Given:
Δ LMN and Δ LKN are connected at side LN.
As per the information,

0.84 is 10 times as much as 0.084

Given:
population mean, μ =135
population standard deviation, σ = 15
sample size, n = 19
Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.
Estimate of sample mean

Estimate of sample standard deviation


to 5 decimal places.
Thus, using the normal probability table,





Therefore
The probability that the mean weight is between 125 and 130 lbs
P(125<X<130)=0.0731166-0.0018308
=
0.0712858
Add both pair of shoes together. Then take that total and multiply by7% or.07
the answer is -10 you just multiply 3 times -2 and then subract 4
