How would I find the mean, median and mode ?
snow_tiger [21]

Answer:

Mode is the number that occurs most often in the data set. lets say i have the numbers(6,9,2,0,3,2,1,2) it would be two because there are more two's than any other number in the data set.

Mean is found by adding all of the numbers together in the data set. you simply add your numbers together.

Median is the number that is found halfway in the data set. for example if i had the numbers (6,9,2,5,0,2,1) the median would be 5.

I hope this helps you!

Help me answer this and explain it please! :)
Fynjy0 [20]

Answer:

90. 04987916

Step-by-step explanation:

Let HI be a

and GH be c

and GI be b

and <GHI be B

Using the law of Cosines,

b^2= -2ac cos (B) + c^2 + a^2

= -2(42)(60) cos (123)+60^2+42^2

= -5040 cos (123) +3600+1764

= -5040(-0. 544639035) +5364

= 2744. 980736+5364

b^2= 8108. 980736

b= Sqrt ( 8108. 980736)

b= 90. 04987916

345 ft/min = ___________ ft/h
Pavlova-9 [17]

the rate given is 345 ft/min

this means within 1 min distance is - 345 ft

we have to convert this speed to ft/h

1 hour is equivalent to 60 minutes

so if 60 minutes equals 1 hour

1 minute is equal to - 1/60 hr

so the distance within 1 minute is - 345 ft

since 1 min = 1/60 hr

distance within 1/60 hour = 345 ft

therefore distance in 1 hour = \frac{345}{1/60} = 345 * 60 = 20 700 ft

answer is 20 700 ft/h
