The mean length of 10 childrens' big finger is 8.1cm.
sergiy2304 [10]

Answer:

  • The mean length of 10 children's big finger is 8.1 cm

Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.

  • The mean length of 11 adult's big finger is 14.1 cm

Average length of all the 11 adult's big finger is (14.1×11) cm =155.1

  • Mean length of these 21 people's big finger is
  • \frac{(81 + 155.1)}{21}  = 11.242857
  • Hence, <em><u>11.24</u></em> is the right answer.

Use the following information for questions 1 through 6. The dietitian at a camp is planning breakfast for the first day of camp
Dima020 [189]

Answer:

Let x and y be the pieces of toast and sausage required.

Then the objective function is

Min Z=0.04x+0.08y

Constraints:

Vitamin A, 2x+4y≥20

Vitamin B, 3x+1.5y≥15

Iron, 2x+2y≥16

Sausage, y≤4

The non-negative constraints are x≥0, y≥0

Thus, the linear programming model is

Min Z=0.04x+0.08y

Subject to,

2x+4y≥20

3x+1.5y≥15

2x+2y≥16

y≤4

x≥0, y≥0

1) There are two variables in the LP model. So, option (B) is correct.

2) The LP model contains four constraints (excluding the non negative constraints). So, option (D) is correct.

3) Solving the LP model using a software, we get the solution as

z=0.4, at x=6 and y=2

So, The cost of the breakfast is $ 0.4. Option (B) is correct.

4) The breakfast should contains 6 toasts.

5) The amount of Vitamin B in the breakfast = 3(6)+1.5(2)=18+3=21 milligrams. So, option (C) is correct.

6) The amount of Iron in the breakfast= 2(6)+2(2)=12+4=16 milligrams. So, option (B) is correct.
