2x-6=0
2x-6+6=0+6
2x=6
2x/2=6/2
x = 3
Answer:
Slope is 2
Step-by-step explanation:
use the y2 - y1 / x2 - x1 method
9 - 5 = 4
over
6 - 4 = 2
so the slope is 2
Answer:
0.6826
Step-by-step explanation:
Mean(μ) = 37
Standard deviation (σ) = 9
P(28 < x < 46) = ???
Using normal distribution
Z = (x - μ)/σ
For x = 28
Z = (28 - 37)/9
Z = -9/9
Z = -1
For x = 46
Z = (46 - 37)/9
Z = 9/9
Z = 1
We now have
P(-1 < Z < 1)
= P(Z < 1) - P(Z < -1)
From the table, Z = 1 = 0.3413
φ(Z) = 0.3413
Recall that
When Z is positive, P(x<a) = 0.5 +φ(Z)
P(Z<1)= 0.5 + 0.3413
= 0.8413
When Z is negative, P(x<a) = 0.5 - φ(Z)
P(Z< -1)= 0.5 - 0.3413
= 0.1587
We now have
0.8413 - 0.1587
= 0.6826
Thank you for posting your question here. Below is the solution:
ark worked 5 2/3 + 9 1/3 = 15 hours. 8 3/5 + 9 2/5 = 18 hours + 9 hours.
<span>15 + 18 + 9 = 42 hours worked @ $6.55 per hour </span>
<span>40 hours regular pay and 2 hours overtime. </span>
<span>Over time is 1 1/2 X $6.55 = $9.83 per hour X 2 hours overtime worked = $19.65 in over time . </span>
<span>40 hours @ $6.55 = $262.00 + $19.65 = $281.65.Gross pay </span>
<span>Chris. </span>
<span>5 1/2 + 9 1/2 = 15 hours </span>
<span>8 4/5 + 5 1/5 = 14 hours </span>
<span>14 + 15 = 29 hours worked. @ $9.65 per hour = $279.85 Gross pay </span>
