Bob makes three different silverware - spoons, forks and knives. Each unit (dozen) of spoon gives him a profit of $9, forks of $

Gala2k [10]

Answer:

Solution is:

z (max) = 687.5

x₁ = 0

x₂ = 16

x₃ = 21

Step-by-step explanation:

From the problem statement we have:

Resources: machine time ( 183 h) labor (250 h) steel 185 (pounds)

Unit

Spoons 4 4 3

forks 4 9 2

knives5 5 5 4

Profit $ 9 20 17.5

Objective function z = 9*x₁ + 20*x₂ + 17.5 *x₃ to maximize

Subject to:

Availability of machine time : 183 h

4*x₁ + 4*x₂ + 5*x₃ ≤ 183

Availability of labor : 250 h

4*x₁ + 9*x₂ + 5*x₃ ≤ 250

Availability of steel : 185 pounds

3*x₁ + 2*x₂ + 4*x₃ ≤ 185

Requirement:

x₂ ≥ 16

General constraints:

x₁ ≥ 0 x₃ ≥ 0 all integers

After 6 iteration the solution using AtomZmath on-line solver

z (max) = 687.5

x₁ = 0

x₂ = 16

x₃ = 21

Resources used:

Machine time: 16* 4 + 21*5 = 64 + 105 = 169

remains 183 - 169 = 14 h

Labor: 16*9 + 21* 5 = 144 + 105 = 249

remains 250 - 249 = 1 h

Steel : 16*2 + 21*4 = 32 + 84 = 116

remains 185 - 116 = 69 pounds.

If it is decided that 20 units of forks are to be made then

we will need 4*4 = 16 h of machine time

9*4 = 36 h of labor

2*4 = 8 pounds of steel

We can get that from abandom to make one unit of x₃ ??

No because as we said we need 36 hours of labor ( we still have 1 we need 35 more hours ) if we make 20 x₃ insted of 21 we get only 5 hours.

z we got is maximum

In order to help identify baby growth patterns that are unusual, we need to construct a confidence interval of the mean head cir

sukhopar [10]

Answer:

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).

Step-by-step explanation:

Our sample size is 100.

The first step to solve this problem is finding our degrees of freedom, that is, the sample size subtracted by 1. So

$df = 100-1 = 99$ .

Then, we need to subtract one by the confidence level $\alpha$ and divide by 2. So:

$\frac{1-\alpha}{2} = \frac{0.01}{2} = 0.005$

Now, we need our answers from both steps above to find a value T in the t-distribution table. So, with 99 and 0.005 in the t-distribution table, we have $T = 2.626$

Now, we find the standard deviation of the sample. This is the division of the standard deviation by the square root of the sample size. So

$s = \frac{1.6}{\sqrt{100}} = 0.16$

Now, we multiply T and s

$M = Ts = 2.626*0.16 = 0.42$

For the lower end of the interval, we subtract the sample mean by M. So the lower end of the interval here is

$L = 40.6 - 0.42 = 40.18$ cm

For the upper end of the interval, we add the sample mean and M. So the upper end of the interval here is

$L = 40.6 + 0.42 = 41.02$ cm

So

The 99% confidence interval estimate of the mean head circumference of all 2-month-old babies is (40.18cm, 41.02cm).
