Answer:
Range = 7
Mode = 1
Step-by-step explanation:
Given the data
8, 1, 1, 6, 2, 2, 1, 1,8
Range = Highest value in the data - Lowest value in the data
Highest value = 8
Lowest value = 1
Range = 8 - 1
Range = 7
The mode is the data value that is occurring most. from the set of data, we can see that 1 is occurring four times (most frequent). Hence the mode of the data is 1
When dealing with fractions, take the whole as 1.
in this case, the whole class is 1;
fraction of votes for Andrew: 1-1/2 -1/4 - 1/5
these fractions have different denominators (bottom), to continue, you have to make the denominators the same;
to do that, I usually count by the largest one. In this case, it is a 5. 5 is not divisible by 2 or 4, so I move on to 10. 10 is still not divisible by 2 and 4, so try 15, then 20.
20 works, so make all the denominators to 20. Remember 1 is 20/20:
20/20- 10/20 -5/20 -4/20 =1/20
so the fraction of votes Andrew got was 1/20.
For answer b, the whole is no longer 1. the whole is now 100.
1/2 of 100=50 for Amy
1/4 of 100=25 for Sophie
1/5 of 100=20 for Ryan
1/20 of 100=5 for Andrew
Notice the numbers add up to be exactly 100
Answers: Expression is the radical of 13+13, so the correct answers are both A and D
Answer:
k = 9/8
y = 9/8x
Step-by-step explanation:
45/40 = 9/8
To check:
40 * 9/8 = 45
Hope this helps!
(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
