The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.

Answer:
t is the x-intercept
and it represents the weeks
Step-by-step explanation:
Given that F is a distribution function then it is going to be said to be non decreasing.
<h3>How to define the random variable</h3>
Let Y = F(x)
Then we have a distribution function that we can define to be
Gy(Y) = P(Y≤y) = P[F(X)≤y]
= P[x≤F⁻¹(y)]
The inverse is said to exist given that the value F is non decreasing and it is also said to be continuous.
Such that Gy(Y) = F[F⁻¹(y)]
then we have to see f to be the distribution of x
Gy(Y) = y
The PDF of Y is denoted as Y = F(X)
then we would have
d/dy [Gy(Y)] = 1
Given that F is a df, then the value of the distribution function would always be 0, 1.
gy(y) would then have to be 1
0 ≤ y ≤ 1
This tells us that F(X) is a uniform variate of 0,1.
