Answer:
16
Step-by-step explanation:
Simply plug in 2 for a, then 6 for b and substitute
(2+6)2
Then do order of operations to simplify PEMDAS
First what's inside the parenthesis
(8)2
Then multiply
16.
Answer:The mode if 5, because 5 occurs 8 times, which is more than any other numbers occurring more than once. The median is 6, and this is because when you line up the numbers in order and cross them off to find the middle number, it is 6. I rounded to the mean to about 6.4. I got this by adding all of the numbers up, or by doing 12 + 40 +18 +7, etc, and got the total of 165. Because there is a total of 26 data points, I divided those numbers and got 6.3461, which ends up rounding to 6.4.
Step-by-step explanation:
Median is the middle number and you have to put each set in order like you've done, tick each number off and each side working in:
3,4,-6-,7,8 =6
3,3,-4-,5,5 =4
6,7,-7-,8,9 =7
2,2,-3-,4,6 =3
Mode is the number that shows up the most
3,4,6,7,8= no mode
3,3,4,5,5= 3 and 5
6,7,7,8,9=7
2,2,3,4,6=2
6,7,7,8,9 both have 7 for mode and median
Answer:
y = -2x
Step-by-step explanation:
Find the slope and y-intercept to write an equation in the form y = mx + b
Slope = - 20/10 so -2, m = -2 since the line goes down to the right
Then it crosses the y-axis at (0,0) so b = 0 [which is the y value]
Put it all together y = -2x + 0 so y = -2x
Answer:
y = 3/2x + 2
Step-by-step explanation:
first things first write the equation is y = mb+b form which would be 2y = 3x + 14 then divide everything by 2 to get y by itsself --> 3/2x + 7 for an equation to be paralle the equation needs the same slope which is -6 so 3/2(-6) = -9 so the next equation would also start with 3/2x, so you would then do this:
-11 = -9 + b (y = mx+b)
b = -9 + 11 --> b = 2
so the equation is
y = 3/2x + 2
