Please look up "volume of a cylinder."
The formula for the volume of a cylinder of radius r and height h is
V = pi*r^2*h
So, if r = 1.5 m and h = 10 m, the volume of the tank is
V = pi*(1.5 m)^2*(10 m) = 70.69 cubic meters.
Answer:
A = 5t +7000
Step-by-step explanation:
Tim's rate of increasing altitude is 5 ft/min, so his change in altitude in t minutes is 5t.
If he started at 7000 ft, his altitude as a function of time is the sum of his initial altitude and his change in altitude:
A = 5t +7000
So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!
Make an equation:
J = 1/2F - 10
Where 'J' represents Justin's age and 'F' represents his Father's age.
Plug in 12 for J:
12 = 1/2F - 10
Add 10 to both sides:
22 = 1/2F
Divide 1/2 to both sides or multiply by its reciprocal, 2:
F = 44

Step-by-step explanation:
1) Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
2) Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For what proportion of groups will at most two of the households have cable tv?
So we want to find this probability:
