A cylindrical can has a volume of 16 cm 3. What dimensions yield the minimum surface area? 1. The radius of the can with the mi

kykrilka [37]

Answer:

radius = 1.37 cm

height = 2.71 cm

Step-by-step explanation:

We are given volume = 16 m³.

Formula for volume of a cylinder is;

V = πr²h

Thus,

πr²h = 16

h = 16/πr²

Now formula for the surface area is;

S = 2πr² + 2πrh

Putting 16/πr² for h gives;

S = 2πr² + 2πr(16/πr²)

S = 2πr² + 2π(16/πr)

S = 2π(r² + 16/πr)

To minimize, we will find the derivative of S and equate to zero

S' = 2π(2r - 16/πr²) = 0

4πr - 32/r² = 0

4πr = 32/r²

r³ = 32/4π

r = ∛(32/4π)

r = 1.37 cm

From h = 16/πr²;

h = 16/(π × 1.37²)

h = 2.71 cm

X = 2y + 12 5x + 3y =-44

Dmitry [639]

Answer:

(-4, -8)

Step-by-step explanation:

Note that x in terms of y is x = 2y + 12. Substitute 2y + 12 for x in the second equation:

5(2y + 12) + 3y = -44

10y + 60 + 3y = -44

Then 13y= -104, and y = -8

From the first equation we find x = 2(-8) + 12, or x = -16 + 12, or x = -4

Then the solution is (-4, -8)

negative binomial rv is the number of failures that occur before the rth success in a sequence of independent and identical succ

astra-53 [7]

Answer:

The probability mass function (pmf) of X is:

$P(X=k)={{k+r-1}\choose k}\cdot (1-p)^{k}\cdot p^{r};\ k=1,2,3,...$

Step-by-step explanation:

The random variable X is said to be a Negative Binomial random variable.

The random variable X is defined as the number of failures in a series independent and identical Bernoulli trials, before a specific number of success takes place.

For example, consider rolling a 5 on a six-sided die as the success and any other number as failure. Then the number of rolls before 5 occurs three times in a row can be defined as a negative binomial experiment.

The probability mass function of a negative binomial random variable X is:

$P(X=k)={{k+r-1}\choose k}\cdot (1-p)^{k}\cdot p^{r};\ k=1,2,3,...$

Here,

k = number of successes

r = number of failures

p = probability of success
