Answer:multiplication Ex: 3 x 2 = 6
Division Ex: 6/2 =3
Step-by-step explanation:
3 x 2 = 3+3, add 3 2 times
6/2 = How many 2’s go into 6
Answer:
Step-by-step explanation:
9y-4 = 50
9y = 54
y= 6
9y-4+7x+xy = 180
9(6)-4+7x+6x= 180
54-4+13x = 180
13x+50 = 180
13x = 130
x = 10
The mean absolute deviation of the set of numbers is 5/4
<h3>How to determine the
mean absolute deviation?</h3>
The set of numbers is given as:
1 1/2, 0, 4 and 2 1/2
Rewrite the set of numbers as:
1.5, 0, 4 and 2.5
Calculate the mean of the set using:
= Sum/Count
So, we have:
= (1.5 + 0 + 4 + 2.5)/4
Evaluate
= 2
The mean absolute deviation is then calculated as:
M.A.D = 1/n * ∑|x - |
So, we have:
M.A.D = 1/4 * [|1.5 - 2| + |0 - 2| + |4 - 2| + |2.5 - 2|]
Evaluate the absolute difference
M.A.D = 1/4 * [0.5 + 2 + 2 + 0.5]
Evaluate the sum
M.A.D = 1/4 * 5
Evaluate the product
M.A.D = 5/4
Hence, the mean absolute deviation of the set of numbers is 5/4

Answer:
E
Step-by-step explanation:
Let's say "s" represents the number of steps you still need to take to achieve your goal of at least 12,100 steps. You've already walked 5204 steps, and if we add this to s, we should get a total of <em>at least</em> 12,100 steps:
s + 5204
The words "at least" means that we need to use ≥, so:
s + 5204 ≥ 12,100
The answer is E.
If we were to solve this inequality:
s + 5204 ≥ 12,100
s ≥ 6896
In other words, you still have to take at least 6896 more steps.
