Answer:

11

Step-by-step explanation:

If the set of numbers are not in least to greatest first set them up into their positions. But since this set is already in least to greatest we can go to the next step.

6, 7, 10, 12, 12, 13

Cross off all numbers until you get to the middle:

6, 7, 10, 12, 12, 13

Find the mean of the numbers in the middle:

10 + 12 = 22

22 / 2 = 11

The answer is 11

Hope this helped.

uranmaximum [27]

Answer:

The degrees of freedom associated with this problem are 16.

Step-by-step explanation:

The degrees of freedom associated with a problem, independent of the confidence level, is the sample size subtracted by 1.

In this problem, we have that:

She takes a random sample of 17 trucks, so the sample size is 17.

This means that the degrees of freedom associated with this problem are 16.

The staff dietician at the California Institute of Trigonometry has to make up a meal with 600 calories, 20 grams of protein, an
Arlecino [84]

Answer:

The amount of rubbery jello=5.038 ounce

Dried fish stick = 4.886 ounce

Mystery meat = 1.526 ounce.

Step-by-step explanation:

Solutions/Explanation: (a) Suppose the amount of rubbery jello = x ounce,  

The dried fish sticks amount to be = y ounce  

The amount of mystery meat = ounce.

Specification of the ingredients

Rubbery jello has: Calories=10 Cal/ounce, Protien=1 gram/ounce, Vitamin C= 30 mg/ounce

Dried fish sticks: Calories=50 Cal/ounce, Protien=3 grams/ounce, Vitamin C=10 mg/ounce

Mystery meat: Calories=200 Cal/ounce, Protien=0.2 gram/ounce, Vitamin C=0 mg/ounce,

Now,  

Total calories = 600.  

Thus,

10x+50y+200z=600\quad\Idot (1)

The, total Protien = 20 g.  

Thus,

x+3y+0.2z=20 \quad\Idot (2)

also, total Vitamin C = .

Thus,

30x+10y+0z=200 \quad\Idot (3)

Therefore,

1, 2 and 3 are the mathematical models of the dietician's problem with a system of three linear equations.

(b) Now, we know three equations:

10x+50y+200z=600

OR  

x+5y+20=60 \quad\Idot (4)

From eqn 2,  

x+3y+0.2z=20 \quad\Idot (5)

From eqn 3.  

30x+10y=200

OR  

3x+y=20 \quad\Idot (6)

On solving the eqn 4, 5 and 6 for x, y and z,

Multiplying eqn 5 by 100,

100x+300y+20z=2000 \quad\Idot (7)

Now, subtract eqn 4 from eqn 7

99x+295y=1940 \quad\Idot (8)

Now, multiplying eqn 6 by 295. we have,

885x+295y=5900 \quad\Idot (9)

Now, subtract, eqn 8 from eqn 9, we get,

786x=3960

x=\frac{3960}{786}

 x=5.038 \quad\Idot (10)

Now, substituting into eqn 6, we get

y=4.886 \quad\Idot (11)

Now, substitute eqn 10 and 11 into eqn 4, we have

z=1.526
