Answer:

$11988

Step-by-step explanation:

Given that,

The unit cost is given by :

C(x)=0.7x^2-462x+88218

We need to find the minimum unit cost.

For minimum cost,

Put \dfrac{dC}{dx}=0

So,

\dfrac{d}{dx}(0.7x^2-462x+88218)=0\\\\1.4x-462=0\\\\x=\dfrac{462}{1.4}\\\\x=330

Put x = 330 in equation (1).

C(330)=0.7(330)^2-462(330)+88218\\\\=\$11988

So, the minimum unit cost is equal to $11988.

The cylinder shown has a radius of 3 inches. The height is three times the radius. Find the volume of the cylinder. Round your s
MrRa [10]

Answer:

254.5 Inches Cubed

Step-by-step explanation:

Formula for Finding the Volume of a Cylinder: V=\pi r^2h

The radius is 3 inches.

r=3

The height is three times the radius.

Multiply the radius by three to get the height.

h=3*3\\h=9

The height is 9 inches.

Use the formula to find the volume.

\pi (3)^29= \pi (9)9=81\pi

The exact volume is 81\pi inches cubed.

81 * \pi ≈ 254.47

254.47 ≈ 254.5

The volume of the cylinder should be about 254.5 inches cubed.

find the probability of exactly two successes in five trials of a binomial experiment in which the probability of success is 50%
HACTEHA [7]

ANSWER: 31.25%

Explaination:

Suppose (x+y)(x+y)^{5} is the binomial distribution with 5 trials. Given that, probability of exactly two success in five trials of a binomial experiment in which the probability of success is 50%.

So, x = 0.5 and y = 0.5

The term

5C2*x²*y³ representing 2 successes and 3 failures.

Now find the value of this term.

5C2*(0.5)²*(0.5)³ = \frac{5!}{2!3!}*(0.5)^{5}

=10*0.03125

= 31.25%
