Based on the given information, determine which company has a lower minimum and find the minimum value. g(x) at (10, 855) f(x) a
Gekata [30.6K]

The minimum production cost of company 2 is greater than the minimum production cost of company 1. We arrived at this value by comparing the production cost of both companies.

<h3>What is meant by minimum production cost?</h3>

The overall cost incurred by a company to manufacture a product or provide services is known as the cost of production.

The objective of every company is to keep this cost at minimum, hence the minimum production cost.

<h3>How do find minimum Production Cost?</h3>

Recall that the production function is given as:

f(x) = 0.25x² - 8x + 600

Inserting the values given by the schedule we have

  1. f(6) = 0.25(6²) - 8(6) + 600 = 561
  2. f(8) = 0.25(8²) - 8(8) + 600 = 552
  3. f(10) = 0.25(10²) - 8(10) + 600 = 545
  4. f(12) = 0.25(12²) - 8(12) + 600 = 540
  5. f(14) = 0.25(14²) - 8(14) + 600 = 537

For company 2, we are given the various production costs as;

x   - g(x)

6  - 862.2

8  - 856.8

10 -  855

12 -  856.8

14 - 862.2

Juxtaposing the above, we can infer that the minimum production cost of company 2 is greater than the minimum production cost of company 1.

Approximate the probability that X is greater than 70 and less than 90.
Dima020 [189]

The probability that X is greater than 70 and less than 90 is; 0.85

<h3>How to find the probability?</h3>

Let X be the binomial random variable with the parameters:

n = 200

p = 0.4

Then, the random variable Z defined as:

Z = (X - np)/(√(np(1 - p)

The probability that X is greater than 70 and less than 90 is expressed as; P(70 < X < 90)

At X = 70, we have;

Z = (70 - (200*0.4))/(√(200 * 0.4(1 - 0.4))

Z = -1.44

At X = 90, we have;

Z = (90 - (200*0.4))/(√(200 * 0.4(1 - 0.4))

Z = 1.44

Thus, the probability would be expressed as;

P(-1.44 < Z < 1.44)

From online p-value calculator, we have;

P(-1.44 < Z < 1.44) = 0.85

Complete question is;

Suppose that X is a binomial random variable with n = 200 and p = 0.4 Approximate the probability that X is greater than 70 and less than 90.
