Answer:
Hello your question is incomplete attached below is the complete question
answer : 192.15 pounds
Step-by-step explanation:
Given :
weight = - 99.41 + 3.94*Height
R^2 = 0.81
SER = 10.2
<em><u>Determine the regression weight prediction</u></em>
Height of man = 74 inches
Hence : weight = - 99.41 + 3.94 * 74 = 192.15
therefore the regression weight prediction = 192.15 pounds
The square root of 81 is 9, this can be proven by squaring 9, which's result is 81.
Using integration, it is found that the area between the two curves is of 22 square units.
<h3>What is the area between two curves?</h3>
The area between two curves y = f(x) and y = g(x), in the interval from x = a to x = b, is given by:

In this problem, we have that:
.
Hence, the area is:


Applying the Fundamental Theorem of Calculus:


The area between the two curves is of 22 square units.

Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
Y=-3x+1 this is the answer I think
