Answer:
Last option
Step-by-step explanation:
I think it would be the last option because when you reflect over the x-axis, the x-axis switched signs.
So, -8 would be 8 , -7 would be 7, and 3 would be negative 3.
Dont think the y-axis value would change..
Hope this helps!
(If this was good..please give brainly.)
Answer:
0
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-4)/(4-(-8))
m=0/(4+8)
m=0/12
m=0
The triangle (call it <em>T </em>) has base and height 4, so its area is 1/2*4*4 = 8. Then the joint density function is
where <em>T</em> is the set
(a) I've attached an image of the integration region.
(b) <em>X</em> and <em>Y</em> are independent if the joint distribution is equal to the product of their marginal distributions.
Get the marginal distributions of one random variable by integrating the joint density over all values of the other variable:
Clearly, , so they are not independent.
We have been given a sphere with radius 8.6 ft. We are asked to find the surface area of the given sphere.
We know that surface area of a sphere is equal to .
Upon substituting in surface area formula, we will get:
Upon rounding to nearest hundredth, we will get:
Therefore, the surface of the given sphere would be approximately .
