Answer:
(-1,1)
Step-by-step explanation:
To find where both lines intersect, solve for x and y with substitution.
Equation 1.
-8x+3y=11
Equation 2.
y=3x+4
Substitute y from equation 2 into equation 1.
-8x+3(3x+4)=11
-8x+9x+12=11
x=-1
Now plug x into the second equation to solve for y.
y=3(-1)+4
y=-3+4
y=1
Both lines intersect at (-1,1)
Answer: The conclusion cannot be confirmed unless we have the statistic of the men.
Step-by-step explanation: Only looking at the number of women in both times 8 am and 10 am, will not determine if the men prefer of do no prefer earlier classes. We would need the men's statistics as well for both time slots. There may be more men among the 8 am slot e.g 25 women and 30 men. There is incomplete information to come up with a sound conclusion.
Since the height of the pyramid is 3 times the radius of the cone we can
express height of the pyramid as a function of radius of the cone.
Let radius of cone = r
Then, height of the pyramid = 3r
Area of the base of the cone = pi x r^2 = area of the pyramid.
If the base dimensions of the pyramid are l and b, then area of the pyramid, l x b = pi x r^2.
The volume of the pyramid = 1/3 x l x b x h
We know, l x b = pi x r^2 and h = 3r.
Thus, volume of pyramid is = 1/3 x pi x r^2 x 3 r = pi x r^3
