X=2
its x=2 because you have to divide -20x by -40 so the two negatives cancel out each other and then you get 2.
Answer:
d. each trial has exactly two outcomes whose probabilities do not change
Step-by-step explanation:
A binomial experiment is one where there are exactly two outcomes for each trial and probability for getting success is constant in each trial.
In other words, each trial is independent of the other.
The trials need not be continuous nor time between trials to be constant.
Since trials are to be independent, each trial cannot influence the next.
Only option d is right.
d. each trial has exactly two outcomes whose probabilities do not change
Examples are tossing of coins, throwing dice, drawing cards or balls with replacement, etc
Answer:
A.(26)X =1
26x =1
divide both sides by 26 to make x the subject
26x/1=1/26
x = 1/26
Step-by-step explanation:
B 50(x) =1
50x =1
x =1/50
Answer:

Step-by-step explanation:
We are given

Let's assume it can be factored as

now, we can multiply right side
and then we can compare it


now, we can compare coefficients



now, we can find all possible factors of 48
and then we can assume possible prime factors of 48





Since, we have to find the largest value of n
So, we will get consider larger value of r because of 5r
and because n is negative of 5r+s
so, we will both n and r as negative
So, we can assume
r=-48 and s=-1
so, we get


1 cubic foot = 7.48 gallons
hence

unit conversion

3000 x 7.48 =22440
