Answer:
The correct answer is "(18, 30) minutes".
Step-by-step explanation:
Mean,
= 24
Standard deviation,
= 2
The range of minutes where 99.7% of individuals completed the quiz will be:
= 
On substituting the values, we get
= 
= 
now,
= 
= 
Or,
= 
= 
i.e., 18 to 30 minutes
Answer:
2
Step-by-step explanation:
We can use 2 points to find the slope
m = (y2 -y1)/(x2-x1)
Using ( 0,1) and (1,3)
= (3-1)/(1-0)
= 2/1
= 2
we are given
In A 4 year period, About 80,000 acres of coastal wetlands in United States are lost each year.
so, total area =80000 acres
total time = 4 years
now, we can use formula
total change in wetlands = ( total area)/(total time)
now, we can plug values
total change in wetlands is

Answer:
Y= 20
X= 25
Step-by-step explanation:
The angles of a triangle have to equal 180
So
80+60 = 140
180 - 140 = 40
40/2 = 20
Y = 20
The angles of a linear line split equal 180
So
2y is one side of it which we learned Y = 20 which makes that side 40
To find the other side just guess and check
6(25) = 150
150 - 10 = 140
So the 2y = 40 and the (6x-10) = 140
So yea boom done
