Answer:
(a) 1, 2, 3, 6, 8
Step-by-step explanation:
Given
Required
The sequence of hours worked each day
<em>See attachment for options</em>
From the question, we understand that:
This means that, the middle number is 3 (when sorted)
So, we can conclude that (b) and (c) cannot be true because their middle numbers are 6 and 5 respectively
Next, is to determine the mean of (a) and (d)
The mean of a data is calculated as:
So, we have:
(a)
(d)
Option (a) is true, because it has:
Answer: y=-12
Step-by-step explanation: 4(6-x) -2(6-y)=-4x
24-4x-12+y=-4x
12-4x+y=-4x
y=-12
Answer:
x=46.8
Step-by-step explanation:
4x-29x =234
Combine like terms
-5x = 234
Divide each side by -5
-5x/-5 =234/5
x = 46.8

Step-by-step explanation:
<u>Step 1: Define</u>
2(3x - 1) ≥ 4x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 2: 6x - 2 ≥ 4x - 6
- Subtract 4x on both sides: 2x - 2 ≥ -6
- Add 2 on both sides: 2x ≥ -4
- Divide 2 on both sides: x ≥ -2
Here we see that any value <em>x</em> greater than or equal to -2 would work as a solution.
