Take the -3/5 and add it to 1/30 which would equal 19/30, so x= 19/30
The answer is 65 if your wondering why you have to put the numbers from least to greatest then find the one that is in the middle
Answer:
<em>Expected number of students would have a driver's license = 6</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given data In a class of 25 students, 15 of them have a driver's license
The sample proportion

Let 'X' be the binomial distribution
Given sample size 'n' = 10
<em>mean of the binomial distribution or expected number of students would have a driver's license</em>
μ = n p
= 10 × 0.6
= 6
<u><em>Conclusion</em></u>:-
<em>Expected number of students would have a driver's license = 6</em>
Solution here,
dimentions of is 20 in. by 10 in. by 12 in.
i.e. volume of tank=20×10×12=2400 cu. in.
Again,
the tank holds 10 gallons of water
i.e. 10 gallons of water occupies 2400 cu. in.
so, 1 gallon of water occupies 2400/10 cu.in.
=240 cu.in
