Answer:

122.0627kg

Step-by-step explanation:

The standard deviation is the square root of the variance.

That means:

\sigma =  \sqrt{variance}

From the question, the standard deviation of the weights of the 10 random subjects is 11.0482kg

We substitute to get:

11.0482 =  \sqrt{variance}

We square both sides to get:

11.0482^{2} = variance

122.0627 = variance

Therefore the variance is 122.0627kg

umka2103 [35]

Answer:

Step-by-step explanation:

From the problem statement, we can create the following equation:

T = 100A + 40F

Where T is the total worth of all shares, A is the price of an Apple share, and F is the price of a Ford share.

Plugging in the numbers from the problem statement, we get the following:

T = 100(536) + 40(9.85)

Multiplying these numbers out and adding them together will give you your answer.
