Answer:
80 square m
Step-by-step explanation:
We are given that
Mean=150 m
S.D=4 m
We have to find the variance of the total length of the wire in the coils.
Let X1, X2,X3,X4 and X5 are random variable of sample space of coil are choosing.
Var for all i=1 to 5
Let X be the total length of coils
Hence, the variance of the total length of the wire in the coils=80 square m
Answer:
126°
Step-by-step explanation:
<u>Circle Theorem vocabulary</u>
- <u>Chord</u>: a straight line joining two points on the circle.
- <u>Inscribed angle</u>: the angle formed (vertex) when two chords meet at one point on a circle.
- <u>Arc</u>: the curve between two points on the circumference of a circle
- <u>Intercepted arc</u>: the arc that is between the endpoints of the chords that form the inscribed angle.
<u>Inscribed Angle Theorem</u>
The measure of an <u>inscribed angle</u> is half the measure of the <u>intercepted arc</u>.
Therefore:

Answers:
The graph has a y-intercept of 2 and is shifted to the right 6 from the parent function.
The parent function, y=√x, looks like a parabola laid on its side. We generally only consider the positive square root unless told otherwise. Since we have √(x-6) instead of just √x, the graph is shifted to the right 6 units. The +2 at the end of the equation shifts the graph up 2.
Length x Width x Height = Answer so 7 x 6 = 42. Volume is 42.
