Answer:
In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were:
Inches of Rain 1 2 3 4 5 6
Frequency 2 4 3 3 7 3
The mean (¯xx¯) rain intensity: ____ inches (Please show your answer to 1 decimal place.)
The median rain intensity: __3.8__ inches
Step-by-step explanation:
the answer is 3.8
The answer is x = -2. The steps are in the image below.

Answer:
Increase of 8
Step-by-step explanation:
x = y-8
y=x+8
<span>given:
bull's eye radius= x
width of surrounding rings=y
solution:
Radius of the circle=x+4y
Area of the outermost ring=Area of the circle-Area of the penultimate ring
=Ď€(x+4y)^2-Ď€(x+3y)^2
=Ď€(x^2+8xy+16y^2-x^2-9y^2-6xy)
=Ď€(2xy+7y^2)
hence the area of the outermost ring in terms of x and y is π(2xy+7y^2).</span>
