Leno4ka [110]

Answer:

Johnny and his family left home at 10:00.

Step-by-step explanation:

First, You add all of the minutes up,  

45+20+10= 75

Then convert the minutes to hours,  

75 mins = 1 hr and 15 mins.

Add the hours together,

1 hr + 2 hrs = 3 hrs

Then add minutes,

3 hrs and 15 minutes

Subtract 3 hrs and 15 mins from 13:15,

13.15 - 3.15 = 10:00

Your answer is:  

Johnny and his family left home at 10:00.

A family goes grocery shopping every week. in a month the costs of the groceries are $72.42, $91.50, $58.99, and $69.02. 5. what
frozen [14]
1) Mean
The mean is given by the sum of the data divided by the number of data (4, in this case):
\mu =   \frac{1}{N} \sum x_i = \frac{1}{4}(72.42+91.50+58.99+69.02) = \frac{291.93}{4}=72.98 $

2) Standard deviation
The standard deviation is given by:
\sigma =  \sqrt{ \frac{1}{N} \sum (x_i-\mu)^2 }
where \mu is the mean, that we already found at point 1), and N=4. Substituting data, we have:
\sigma =  \sqrt{ \frac{1}{4} ((-0.56)^2+(18.52)^2+(-13.99)^2+(-3.96)^2) } =
= \sqrt{ \frac{1}{4}  (554.71)} = \sqrt{138.68} =11.78 $
