garri49 [273]

Answer:

The standard deviation of given data is 12.36  

Step-by-step explanation:

We are given the following data in the question:

40, 12, 17, 25, 9, 46, 13, 22, 16,7

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}  

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{207}{10} = 20.7

Sum of squares of differences =

372.49 + 75.69 + 13.69 + 18.49 + 136.89 + 640.09 + 59.29 + 1.69 + 22.09 + 187.69 = 1528.1

\sigma = \sqrt{\dfrac{1528.1}{10}} = 12.36

Thus, the standard deviation of given data is 12.36

morpeh [17]
They would meet after 4 hours, as 65 x 4 = 260. And 60 x 4 = 240. If you add these, they become a value of 500. This also answers the 2nd question ; 65x + 60x = 500.

Tim is running extremely late and has just 5 minutes to return his rental car to the agency. The fuel tank in the car is half em
Whitepunk [10]

Answer:

B

Step-by-step explanation:

Although this problem is quite long and exhausting, it is deceptively simple.

We know that his 12-gallon fuel tank is only half full, so we know that the car needs 6 more gallons of fuel.

If he turns in the car late, he will have to pay y = 2.59x + 32.00, where x is the number of empty gallons (in this case, 6)

In this case, he will pay 2.59(6) + 32.00 = $47.54

If he turns in the car on time, he will have to pay y = 4.50x + 5.00, where x is the number of empty gallons (still 6).

In this case, he will pay 4.50(6) + 5.00 = $32.00

Using these results, we know that B must be true.
