X+2y
Plug in the variables
4+2(7)
4+14
x+2y=18
Answer:
0.9812
Step-by-step explanation:
Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds
For a sample of 9 people std error of sample would be
Thus we find that sample mean is N(175, 12)
The plane will lift safely if sample average <200 pounds
i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)
=
~0.981
If one side is 8 inches then 8/2 is 4
to fill one face, 4 × 4 = 16
to fill a cube 16 × 4 = 64
Answer: 64 cubes will fit
Answer:
I don't know this exactly, but I'll give it my best go!
We can get the answer by answering questions we know are true and eliminating the ones we don't.
E: Experimental probability can be written in the form of a ratio.
- Any probability can be expressed by a ratio so this is true.
B: Experimental probability is the same as theoretical probability.
- They are two different 'types' of probability so this is most likely false.
A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.
- I'm fairly certain that applies to theoretical probability, not experimental.
So that means the answers are most likely C, D, and E. If I was wrong let me know!
