Answer: V≈ 394.57m³
Step-by-step explanation:
We are given:
sample size= n = 45
sample mean = x = 61,300
sample standard deviation =18,246
Since the population standard deviation is not known we will use t distribution to find the confidence interval.
Confidence interval = 99%
Degrees of freedom= n - 1 = 45 – 1 = 44
Critical t value = 2.692
The 99% confidence interval will be:
Thus, the 99% confidence interval for the population mean is:53978 to 68622

Answer:
Graph 1 ➡ y = 1/5 x + 3
Graph 2 ➡ y = 3x
Graph 3 ➡ y = -3x + 5
Graph 4 ➡ y = 1/3 x + 5
Step-by-step explanation:
Remember that slope is basically rise/run, where rise is up and down movement and run is left and right movement.
Also remember the formula for slope is y=mx+b, where m is slope and b is y-intercept. Additionally if y-intercept is 0 you don't write it.
Hope this helps :)
5,486 plus 8,602 is equal to around 14,000, give or take.
