Answer:
6x+1
is that one of your choices ?
4x-6
Step-by-step explanation:
first you multiply the 2 and the -7 to get -14.
afterwards you add the 8 and the -14 to get -6.
you can't do anything with the 4x because we don't know what the x is.
Your answer should be 4x-6.
All of this is easily solved using PEMDAS
(parentheses, exponents, multiplication, division, addition, subtraction)
First one:
Both the mean and median are greater for Plot A than for Plot B
Set A:
Mean:
[1×10 + 2×7 + 2×6 + 2×5 + 2×4 + 1×3]/10
= 5.7
Median:
Median position: (10+1)/2 = 5.5th value
(5+6)/2
Median = 5.5
Set B:
[1×7 + 3×6 + 3×5 + 2×4 + 1×3]/10
= 5.1
(5+5)/2
Median = 5
Mean: A is greater
Median: A is greater
I think the answer is going to be
x=9
