Answer:
Step-by-step explanation:
Range = difference between the highest and the lowest
Mode = Data that occurs the most time
Median = Arrange the data in ascending order. The middle data is the median. If number of data is even, median is the average of the two middle terms.
1) Range = 28 -21 = 7
Mode = 25
Number of data (Count the total dots) = 14
Median = average of 7th and 8th term
Median = (25+25)/2 = 50/2 = 25
2) Range = 0.18 - 0.11 = 0.07
Mode = 0.15 and 0.16
Number of data = 23
Median =12th term = 0.15
Four? Isn't it stated in the question? Unless I am assuming wrong.
<span>DH = x + 2, HF = 2y, GH = 3x – 3, and HE = 5y + 1
DH = HF
</span>x + 2 = 2y
and
GH = HE
3x – 3 = 5y + 1
so now you have
x + 2 = 2y
3x – 3 = 5y + 1
re-write and simply
x = 2y - 2
3x = 5y + 4
substitute x = 2y - 2 into 3x = 5y + 4
3x = 5y + 4
3(2y - 2) = 5y + 4
6y - 6 = 5y + 4
y = 10
x = 2y - 2
x = 2(10) - 2
x = 20 - 2
x = 18
answer
x = 18 and y = 10
Answer:
1. 3(x^2+10x-24)
Step-by-step explanation:
3x^2 +30x-72
so you want to see what each element has in common with the whole equation. In this case, everything is divisible by 3 so we take out the 3.
3(x^2+10x-24)
Answer:
5%
Step-by-step explanation:
Lets say 10 add a 0 = 100 9.5 add a 0 = 95.0 (move ok decimal place) so there is a 5% error.
