Answer:
z = 1/2
Step-by-step explanation:
Step 1: Write equation
22z + 6 - 10 = 6z + 4
Step 2: Solve for <em>z</em>
- Combine like terms: 22z - 4 = 6z + 4
- Subtract 6z on both sides: 16z - 4 = 4
- Add 4 to both sides: 16z = 8
- Divide both sides by 16: z = 8/16
- Simplify: z = 1/2
Step 3: Check
<em>Plug in z to verify it's a solution.</em>
22(1/2) + 6 - 10 = 6(1/2) + 4
11 - 4 = 3 + 4
7 = 7
Answer:
<h3>20</h3>
Step-by-step explanation:
Standard deviation of the mean is expressed as:
SM = s/√n
s is the standard deviation of all invoices
n is the sample size of the invoiced
Given
s = $200
n = 100
Required
Standard deviation of the mean
Substitute the given parameters into the given equation
SM = 200/√100
SM = 200/10
SM = 20
Hence the standard deviation of xbar is 20
Answer:
x> y-300/12
Step-by-step explanation
1. Subtract 300 from both sides
2. Divide both sides by -12
3. Switch the sides
Answer:
To find the x-intercept of any equation, set the y-value to 0.
Step-by-step explanation:
Example:
y=1x+4
To find x-intercept:
0=1x+4
1. Subtract 4 from both sides
2. Divide both sides by 1
The x-intercept is -4
