Find the mean, variance, and standard deviation of the sample with

azamat

Mean:-

$\\ \tt\hookrightarrow \dfrac{\sum x}{n}=\dfrac{210}{10}=21$

Standard Deviation:-

$\\ \tt\hookrightarrow \sqrt{\dfrac{\sum x^2}{n}-(\sum x/n)^2}$

$\\ \tt\hookrightarrow \sqrt{\dfrac{5006}{10}-(21)^2}$

$\\ \tt\hookrightarrow \sqrt{500.6-441}$

$\\ \tt\hookrightarrow \sqrt{59.6}$

$\\ \tt\hookrightarrow 7.72$

Variance:-

$\\ \tt\hookrightarrow (S. D)^2=(7.72)^2=59.6$

Jamina drove for 2 hours at an average speed of 40km/h. She then drove for 3 hours at an average speed of 50km/h. What was her a

cestrela7 [59]

Remark

Average Speed = Total distance divided by total time.

Total Time

2 hours + 3 hours = 5 hours. The total time is 5 hours.

Total Distance

d = rate * time

d1 = 40 km/hour * 2 hours = 80 km

d2 = 50 km/hour * 3 hours = 150 km

d = d1 + d2

d = 80 + 150 = 230 km

Average Speed

Av = Total distance / Total Time = 230 / 5 = 46 km/hr
