A supply company manufactures masks and ventilators for hospitals. To maintain hugh quality, the company should not manufacture
notsponge [240]

Answer:

20 masks and 100 ventilators

Step-by-step explanation:

I assume the problem ask to maximize the profit of the company.

Let's define the following variables

v: ventilator

m: mask

Restictions:

m + v ≤ 120

10 ≤ m ≤ 50

40 ≤ v ≤ 100

Profit function:

P = 10*m + 65*v

The system of restrictions can be seen in the figure attached. The five points marked are the vertices of the feasible region (the solution is one of these points). Replacing them in the profit function:

point          Profit function:

(10, 100)    10*10 + 65*100 = 6600

(20, 100)    10*20 + 65*100 = 6700    

(50, 70)      10*50 + 65*70 =  5050

(50, 40)     10*50 + 65*40 = 3100

(10, 40)      10*10 + 65*40 =  2700

Then, the profit maximization is obtained when 20 masks and 100 ventilators are produced.

What is the z score associated with 75 percentile
ddd [48]

Answer:

First, determine how many standard deviations above the mean one would have to be to be in the 75th percentile. This can be found by using a z table and finding the z associated with 0.75. The value of z is 0.674. Thus, one must be .674 standard deviations above the mean to be in the 75th percentile

What is the volume of the composite figure? (Round to the nearest hundredth. Use 3.14 for Pi.)
Natasha2012 [34]

The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.

Step-by-step explanation:

The given is,

              Composite figure is combination of a  half sphere and cone

              Both have a radius of 4 centimeters

              The cone has a height of 15 centimeters

Step:1

   Volume of composite figure = Volume of half sphere + Volume of cone  

Step:2

     Formula for volume of semi sphere,

                                    Volume of half sphere, V_{Half sphere} = \frac{2}{3}  \pi  r^{3}

     Where, r - Radius of Half sphere,

     From given, r = 4 centimeters

                                    V_{Half sphere} = \frac{2}{3}  \pi  4^{3}

                                                       = (0.6667) (3.14)  (64)        (∵ \pi = 3.14 )

                                      V_{Half sphere} = 133.9733 cubic centimeters

     Formula for volume of cone,

                      Volume of cone, V_{cone} = \frac{1}{3} \pi r^{2} h

     where, r - Radius of cone

                h - Height of cone

     From given,

                 r = 4 centimeters

                h = 15 centimeters

     Volume of cone,

                                                V_{cone} = \frac{1}{3} \pi 4^{2}(15)    

                                                         = (0.333333) (3.14)(16)(15)       (∵ \pi = 3.14 )

                                                 V_{cone} = 251.1997 cubic centimeters

Step:3

        Volume of composite figure =  133.9733 + 251.1997

       Volume of composite figure  = 385.17 cubic centimeters

Result:

         The volume of composite figure is 385.17 cubic centimeters, if a half sphere and cone have a radius of 4 centimeters and height of 15 centimeters.
