Answer:
Bench costs $325
Step-by-step explanation:
Try setting up an equation
x = cost of garden table
y = cost of bench
equation 1: x + y = 585
We also know that the table costs 65 dollars less than the bench.
cost of garden table = bench - 65
or
equation 2: x = y - 65
Now just substitute equation 2 into equation 1
(y-65) + y = 585
and solve for y
2y-65 = 585
2y = 585 + 65 = 650
y = 325 = cost of bench

The sample of students required to estimate the mean weekly earnings of students at one college is of size 96.04.
For the population mean (μ) , we have the (1 - α)% confidence interval as:
X ± Zₐ / 2 + I / √n
margin of error = MOE = Zₐ / 2 ×I / √n
We are given:
σ = $10
MOE = $2
The critical value of z for 95% confidence level is
Zₐ / 2 = Zₓ = 1.96 ( for x as 0.025)
n = (1.96 (10))²
n = 96.04
Thus, the sample of students required to estimate the mean weekly earnings of students at one college is of size, 96.04.
