Answer:
h = 430
Step-by-step explanation:
1290 = h/10 + h/5 Make h/5 into something that is something / 10
1290 = h/10 + 2h/(5*2) Clean up the brackets.
1290 = h/10 + 2h/10 Add the right.
1290 = 3h/10 Multiply both sides by 10
1290*10 = 10(3h/10)
12900 = 3h Divide both sides by 3
h = 430
"mean" just means arithmetic average...
(22+11+10+14+10)/5=13.4
"median" is the center term (if there is one) or the average of the two center terms in an ordered sequence...so our elements ordered are:
10,10,22,14,22 Since there is a single middle term 22, 22 is the median.
"mode" just refers to the element that occurs most in the set...10 appears twice so 10 is the mode.
