Answer:
don't understand
but mean = <u>summation x</u>
total number
15=<u>7+4+5+2x+11</u>
5
15=<u>27+2x</u>
5
multiply both sides by 5
15×5=<u>2</u><u>6</u><u>+</u><u>2</u><u>x</u> ×5
5
75=26+2x
75-26=2x
<u>49</u>=<u>2x</u>
2. 2
x= 24.5
Answer:lol can somebody please answer this I need an answer I have this question
Step-by-step explanation:
Percent formula : is/of = % / 100
what percent of 21.5 is 55.04...
% = x....because this is what we r looking for
is = 55.04
of = 21.5
now we sub into the formula
55.04 / 21.5 = x / 100
cross multiply because this is a proportion
(21.5)(x) = (100)(55.04)
21.5x = 5504
x = 5504 / 21.5
x = 256 <== so ur answer is 256%
Answer:
Median
Step-by-step explanation:
Median divide a frequency distribution in two equal halves. Median lies at the mid point of any frequency distribution data of any values or quantities.
For example if we have any distribution as [5,7,10,15,8,6.65,12,15,2,3] here 6 will be the median of the distribution as 6 lies at the mid point of the distribution
Answer: Hope it helps :)
<u>-4</u>
7
Step-by-step explanation:
You have to use the formula <u>y2-y1</u>
x2-x1
So <u>-4-4</u>
8--6
-4-4= -8
8--6= 14 (two negative signs become a positive sign)
You have -8 over 14
If you simplify it's -4/7 or <u>-4</u>
7
