Altogether is 400 because total means to add and 200 + 200 = 400. That's the answer to your question.

 Divide 1 hour in the ratio 1 : 9 : 10
olganol [36]

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

x + 9x + 10x = 1 \: hour \\  \\ 20x = 60 \: minutes \\  \\ x =  \frac{60 \: minutes}{3}   \\  \\ x = 3 \: minutes \\  \\ 9x = 9 \times 3 = 27 \: minutes \\  \\ 10x =  10 \times 3 = 30 \: minutes

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes

The sample of eight companies in the aerospace industry, referred to in Exercise 36, was surveyed as to their return on investme
Vera_Pavlovna [14]

Answer:

Sample Variance = 6.008

Sample standard deviation = 2.451

Step-by-step explanation:

We are given the following in the question:

10.6, 12.6, 14.8, 18.2, 12.0, 14.8, 12.2, 15.6

Formula:

\text{Variance} = \displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{110.8}{8} = 13.85

Sum of squares of differences = 42.06

s^2 = \dfrac{42.06}{7} = 6.008

Standard Deviation =

s = \sqrt{s^2} = \sqrt{6.008} = 2.451
