Answer:
40,000
Step-by-step explanation:120,000 divided by 30% is 40,00 because 120,000 divide by 30 is 40,000
Answer:
3xyz
Step-by-step explanation:
The required sum = 7xyz+(−5xyz)+9xyz+(−8xyz)
=7xyz–5xyz+9xyz–8xyz
=(7–5+9–8)xyz
=(16–13)xyz
=3xyz
Answer:
subtraction
Step-by-step explanation:
to start off the process of finding the answer to the equation you would have to subtract 5 from 9
F(-2)=1 the value for y when x=-2 is 1
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
