Answer:
Step-by-step explanation:
The complete question is given thus:
Suppose that computer literacy among people ages 40 and older is being studied and that the accompanying tables describes the probability distribution for four randomly selected people, where x is the number that are computer literate. Is it unusual to find four computer literates among four randomly selected people?
x P(x)
0 0.16
1 0.25
2 0.36
3 0.15
4 0.08
ANSWER:
The odds that this will occur according to the chart are 0.08, or 8%, so although this is unlikely, it's not terribly unusual.
⇒ NO
So from the following we can say it is not unusual to find four (4) computer literates among four randomly selected people.
ok, so P(1) + P(2) + P(3) + P(4) + P(0) = 0.16+0.25+0.36+0.15+0.08 = 1
Whereas the chance of finding four (4) out of four (4) computer iteration is low when compared to other factors.
cheers i hope this helped !!
Answer:
192
Step-by-step explanation:
To find how many phones are expected to be defective, we need to represent the values in a fraction.
x = number of defective phones
Now we can solve this using algebra.
To get the value of x we need to multiply both sides by 8000 to leave x alone.
So around 192 cell phones are expected to be defective out of 8000 phones.
Answer:
The given such number is 6.
Step-by-step explanation:
Let the given such number = m
Now, according to the question, the given expression is:
By the LAW OF EXPONENTS:
⇒Here 
or, the given expression becomes ![m^3 = 216\\\implies m = \sqrt[3]{216} = 6](https://tex.z-dn.net/?f=m%5E3%20%3D%20%20216%5C%5C%5Cimplies%20m%20%3D%20%5Csqrt%5B3%5D%7B216%7D%20%20%3D%206)
or, m = 6
Hence, the given such number is 6.
