<span>Joe got an hourly raise at work and his new rate will be $10.25 per hour.
</span>If r represents the amount of the raise, then the following equation can be written:
X=10.25-r
where X is <span>Joe’s hourly rate was before his raise.
Joe was paid (10.25-r) USD per hour before he got a raise.</span>
The volume of the given composite figure is: 375 m³.
<h3>What is the
Volume of a Composite Figure?</h3>
Volume of the composite figure = volume of triangular prism at the bottom + volume of rectangular prism at the top.
Volume of the composite figure = 0.5 * b * h * length + (l)(h)(w)
= 0.5 * 5 * 4 * 5 + (13)(5)(5)
= 50 + 325
Volume of the composite figure = 375 m³

Answer:
z-interval: (-1.64, 1.64)
90% Confidence interval: (7954,8446)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= $8,200
Sample size, n = 225
Alpha, α = 0.10
Sample standard deviation, s = $750
90% Confidence interval:
Putting the values, we get,
z-interval: (-1.64, 1.64)
(7954,8446) is the required confidence interval.
