A manufacturer produces three models of bicycles. The times (in hours) required for assembling, painting, and packaging each mod
Simora [160]

Answer:

we have to maximize the following equation:

45A + 50B + 55C

where:

A = number of model A bicycles produced

B = number of model B bicycles produced

C = number of model C bicycles produced

the constraints are:

2A + 2.5B + 3C ≤ 4006 (assembly constraint)

A + 0.5B + 2C ≤ 2495 (painting constraint)

A + 0.75B + 1.25C ≤ 1500 (packaging constraint)

A,B,C ≥ 0

using solver, the optimal solution is: 745A + 1006B = $83,825

using slack variables:

2A + 2.5B + 3C + S1 = 4006 (assembly constraint)

A + 0.5B + 2C + S2 = 2495 (painting constraint)

A + 0.75B + 1.25C + S3 = 1500 (packaging constraint)

A,B,C,S ≥ 0

slack variable tableau:

A         B         C           S1          S2          S3           Z            B

2         2.5       3           1             0            0            0            4006

1          0.5       2          0             1            0             0            2495

<u>1          0.75     1.25      0             0           1              0            1500</u>

Marcus pours 12 ounces of cranberry juice into a punch bowl. He uses a container to add sprakling water to the bowl one ounce at
melomori [17]

Answer: There is 20 ounces of liquid in the bowl after adding 8 containers of sparkling water.

Step-by-step explanation:

Since we have given that

Number of ounces of cranberry juice into a punch bowl = 12 ounces

According to question, he uses a container to add sparkling water to the bowl one ounce at a time.

Let the amount of sparkling water added to the bowl be 'x'

Let the total number of ounces of liquid Marcus will have be 'y'.

So, our equation becomes,

y=12+x

Here, we have asked after adding 8 containers of sparkling water .

So, now, our equation becomes,

y=12+x\\\\y=12+8\\\\y=20\ ounces

Hence, there is 20 ounces of liquid in the bowl after adding 8 containers of sparkling water.

The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor s
faltersainse [42]

Answer:

The parameters of the exponential distribution is 0.0133.

Step-by-step explanation:

Exponential distribution is a continuous probability distribution.

The density function of exponential distribution is,  

f _{X}(x)=\theta \cdot e^{-\theta\cdot x},\ x\geq 0

Here the parameter θ is the reciprocal of the mean of the random variable <em>X</em>.

The random variable <em>X</em> has an average value of 75 seconds.

Compute the parameters of the exponential distribution as follows:

\theta=\frac{1}{\mu}\\\\

  =\frac{1}{75}\\\\=0.013333333333\\\\\approx 0.0133

Thus, the parameters of the exponential distribution is 0.0133.
