Answer:
R ≈ 7.4
Step-by-step explanation:
Substitute I = 25000000 into the equation
log(25000000 ) = R , then
R ≈ 7.4 ( to 1 dec. place )
Answer:
B: A systematic random sample
Step-by-step explanation:
Systematic sampling is a type of probability sampling in which members of a larger population are chosen at random from a larger population but at a fixed, periodic interval. This interval, also known as the sampling interval, is calculated by dividing the population size by the sample size desired. Despite the fact that the sample population is chosen in advance, systematic sampling is still considered random if the periodic interval is set in advance and the starting point is chosen at random.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
we are given
![F(d)=0.77d^2-1.32d-9.31](https://tex.z-dn.net/?f=F%28d%29%3D0.77d%5E2-1.32d-9.31)
where
F is the number of board feet
d is the diameter (in inches) of the log
Since, we have to minimize F
so, firstly we will find it's derivative
![F'(d)=0.77\times 2d-1.32\times 1-0](https://tex.z-dn.net/?f=F%27%28d%29%3D0.77%5Ctimes%202d-1.32%5Ctimes%201-0)
![F'(d)=1.54d-1.32](https://tex.z-dn.net/?f=F%27%28d%29%3D1.54d-1.32)
now, we can set it to 0
and then we can solve for d
![F'(d)=1.54d-1.32=0](https://tex.z-dn.net/?f=F%27%28d%29%3D1.54d-1.32%3D0)
![1.54d-1.32=0](https://tex.z-dn.net/?f=1.54d-1.32%3D0)
so, we get diameter as

Answer:
The length of the box is 10 feet.
Step-by-step explanation:
You have to work backwards to find volume, so just divide the volume (100) by the height (2) then divide that by the width (5) and you get your answer, 10
