Answer:
D: All of the above.
Step-by-step explanation:
A. All simple machines are useful in some way, weather that be making it easier to lift heavy objects, activating other machines, or something else.
B. Any simple machine must be, well, simple. i. e. have few moving parts.
Take the lever, for example. It has only one moving part, yet it is still very useful.
C. They can be used to do work. Simple machines can be put together to make something that can do work.
Imagine a windmill that generates power, which then is taken by a motor attached to an Archimedes screw. All of these machines are simple, yet they are still used to do work.
Answer:
Option A is correct.
A uniform distribution.
Step-by-step explanation:
Complete Question
T-Mobile sells 6 different models of cell phones and have found that they sell an equal number of each model. The probability distribution that would describe this random variable is called:
A) Uniform Distribution
B) Continuous Distribution
C) Poisson Distribution
D) Relative Frequency Distribution
Solution
A uniform distribution is one in which all the variables have the same probability of occurring.
It is also known as a rectangular distribution, as every portion of the sample space has an equal chance of occurring, with equal length on the probability curve, leading to a rectangular probability curve.
And for this question, 6 different models of phones sell an equal number, hence, the probability of selling each model is equal to one another, hence, this is evidently a uniform distribution.
Hope this Helps!!!
So I believe it is 13.5 hours because you need to multiply 6 and 18, and the total of that should be divided by 8

Answer:</h3>
All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
15+w−12=15−12+w
Step 1: Simplify both sides of the equation.
15+w−12=15−12+w
Simplify: (Show steps)
w+3=w+3
Step 2: Subtract w from both sides.
w+3−w=w+3−w
3=3
Step 3: Subtract 3 from both sides.
3−3=3−3
0=0
