Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
Answer:
Length is 3 meters and the Width is 5 meters
Step-by-step explanation:
L*W=15
L=2W-7
(2W-7)W=15
(2W+3)(W-5)=0, don't use (2W+3)=0, because it gives you a negative dimension.
W=5, L=3
Answer:
8
Step-by-step explanation:
you solve this by reversing the excercise.
17 + 7 = 24
24/3 = 8
A slope intercept form is, take as an example: y=mx + b, because b is the number where the line intercepts the y axis.
Assuming the space inbetween -7x and 8y is a plus sign.
To get the equation in the right format, one must do the following:
8y=7x-1
y=7/8x-1/8
And theres your answer!
Note: The line intercepts the y axis in -1/8 :)
(If the space isnt a plus, i can answer diffrently in the comments.)
