MN = √2
it comes from √(1^2 + 1^2) = √2 (use phytagoras)
LK = 2 x MN = 2 √2
NK = √(2^2 + 1^2) = √5
ML = NK = √5
so the perimeter
√2 + 2 √2 + √5 + √5
3 √2 + 2 √5
Answer:
x+5
Step-by-step explanation:
Simply it so it is
(x+5)(x+5)/(x+5)
And then you will take out the (x+5) from the numerator and denominator to get the answer.
Answer:
99.7%
Step-by-step explanation:
Given that:
sample size (n) = 655
sample mean () = 43.29
Standard deviation = 2.75
Let's assume we are to estimate the percentage between $33.72 and $51.54
Then;
The test statistics at 33.72 is :
Z at 51.54
Using the empirical standard rule, the percentage will be 99.7%
Answer:
Step-by-step explanation:
Angles around a point add up to 360
x + 53 + 37 + 139 = 360
x + 229 = 360
x = 360 - 229
x = 131
