The estimated sum is 1.75
<span>We know that sin^2(x) = 1 - cos^2(x), so
2 - 2 cos^2(x) = 2 + cos(x)
cos(x) + 2 cos^2(x) = 0
One immediate possibility is that cos(x) = 0, in which case x = Pi/2 or
3pi/4. If cos(x) is not zero, then divide both sides by cos(x) to obtain
cos(x) = -1/2
which gives x = 2Pi/3 and x = 4Pi/3.
So your solutions are
Pi/2, 3Pi/4, 2Pi/3, and 4Pi/3
Hope this helps :D</span>
Answer:
a) Marginal probability of X
b) Marginal probability of Y
c) The probability that the drive-through facility is busy less than one-half of the time is P=0.5.
Step-by-step explanation:
The joint density function of probability is:
a) The marginal density of X is
b) The marginal density of Y is:
c) Probability that the drive-through facility is busy less than one-half of the time. This is P(X<0.5).
A square<span> pyramid </span><span> has 5 faces, 8 edges, and 5 vertices. Remember: A face is a flat side of a solid. An edge is where 2 faces of a solid meet. A vertex is where 3 or more faces meet.</span>
6+5(m+1)=26
6+5m+5=26
11+5m=26
Putting like terms together;
26-11=5m
5m=15
m=3
