The problem would be, 10+6x=4-4x. Then solve the problem by adding or subtracting the lowest variable to the other side and figure out the rest, if you can.
Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
Answer:
y-y1 = m(x-x1)
Step-by-step explanation:
Letter m is the slope.
x1, and y1 is a given point.
Answer: 6.4
Step-by-step explanation:
you take help of ratio in this case.
8/x = 2.5/2
or, (2.5).(x) = (8).(2)
or, x = 16/2.5
so, x = 6.4
The first two numbers of each result are the product of the two numbers
E.g. 8x2= 16- which are the first 2 numbers of 16106
The second set of numbers are the sum of the two numbers
E.g. 8+2=10- which are the next two numbers of 16106
The last set of numbers are the difference between the two numbers
E.g. 8-2= 6- which is the last number in 16106
Just apply this system to all the equations, but take care in noticing whether 1 or 2 digits are involved. Hope this helps!
