Answer:
77.12 feets
Step-by-step explanation:
In a 33' by 69.7' room, what is the diagonal length from corner to corner along the floor?
Step one:
given data
Length of the room= 33 feets
width of the room = 69.7 feets
Required
The diagonal of the room
Step two:
from Pythagoras theorem
z^2= x^2+y^2
substitute
z^2= 33^2+ 69.7^2
z^2=1089+4858.09
z^2=5947.09
z=√5947.09
z=77.12 feets

Answer:
Step-by-step explanation:
Let μ - mean, σ - standard deviation.
<h3>Given:</h3>
A score of 30 falls three standard deviations below the mean:
A score of 60 falls three standard deviations above the mean:
Add up the two expressions and find the value of μ:
- μ - 3σ + μ + 3σ = 30 + 60
- 2μ = 90
- μ = 45
The mean is 45
