Prob ( a tail in one toss) = 1/2
Prob( 3 tails in 3 tosses) = 1/2 ^3
= 1/8 (answer)
5-10(|0.8-3/6|)
5-10(|1/5|)
5-(10)(0.2)
5-2
=3, so C would be your best answer.
Answer:
B) 
Step-by-step explanation:
That is a triangular prism and thus, it has two bases that are triangles, in this case, right triangles, whose hypotenuse is 5 in. long and one of its legs is 4 in. and the other one, 3 in.
The first step is to find the area of both bases like this:

The second step is to get the lateral area, which is compound of three rectangles, hence the process is the following:

Finally, we sum both of the areas found to calculate the total area.

So, the answer is option B).
Try this solution (see the attachmed pictures), modify the design according to the local requirements.
Note, the points (-6;-16) and (-9;-28) are the intersection points of the parabola and the line, given in the condition.
I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1
