For this case we have the following equation:
y = 14.25x
Where,
x: number of hours
y: total salary
For x = 175 we have:
y = 14.25 * (175)
y = 2493.75
The amount of money for unexpected expenses is:
unplanned expenses = 2493.75 - 1250 - 200 - 350 - 400 - 225 - 300
unplanned expenses = -231.25 <0
We note that there is no money left for unexpected expenses

90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
Step-by-step explanation:
<u><em>Step:-1</em></u>
Given that the random sample size 'n' = 50
The sample proportion

90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month

<u><em>Step(ii):-</em></u>
Level of significance = 0.90
Z₀.₉₀ = 1.645


(0.64 -1.645(0.06788) , (0.64 + 1.645(0.06788)
(0.52846 , 0.75166)
<u><em>Final answer:-</em></u>
90 percent confidence interval for the proportion of all students in her district who read at least 1 book last month
(0.52846 , 0.75166)
5≥x-2
add 2 toboth sides
7≥x
x≤7
