Answer:
F. $155
Step-by-step explanation:
For this problem we simply need to multiply the base hourly pay by the amount of hours worked to find the straight-time pay for each week.
$7.75 * 20 = $155
Thus, your weekly pay will be $155.
Cheers.
Replace -6 for x
-32=-4(-6)-2(-6)+4
-32=24+12+4
-32=40
No, x=-6 is not a solution
55/8 or 55:8 will be the unit rate I think

Answer:
The probability that the stock will sell for $85 or less in a year's time is 0.10.
Step-by-step explanation:
Let <em>X</em> = stock's price during the next year.
The random variable <em>X</em> follows a normal distribution with mean, <em>μ</em> = $100 + $10 = $110 and standard deviation, <em>σ</em> = $20.
To compute the probability of a normally distributed random variable we first need to compute the <em>z</em>-score for the given value of the random variable.
The formula to compute the <em>z</em>-score is:
![z=\frac{X-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D)
Compute the probability that the stock will sell for $85 or less in a year's time as follows:
Apply continuity correction:
P (X ≤ 85) = P (X < 85 - 0.50)
= P (X < 84.50)
![=P(\frac{X-mu}{\sigma}](https://tex.z-dn.net/?f=%3DP%28%5Cfrac%7BX-mu%7D%7B%5Csigma%7D%3C%5Cfrac%7B84.5-110%7D%7B20%7D%29)
![=P(Z](https://tex.z-dn.net/?f=%3DP%28Z%3C-1.28%29%5C%5C%3D1-P%28Z%3C1.28%29%5C%5C%3D1-0.89973%5C%5C%3D0.10027%5C%5C%5Capprox0.10)
*Use a <em>z</em>-table for the probability.
Thus, the probability that the stock will sell for $85 or less in a year's time is 0.10.
