Lets get started :)
We need to isolate t from x =
at²
Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²
Take a to the left-hand side { Do division since you see multiplication }
= t²
Take square root since t is to the power of 2
= t
Answer:
62: 300l/hr
63: .018mi/s
64: .46qt/s
65: 298.2mi/hr
Step-by-step explanation:
62: 5x60=300
63: 68/60=1.13/60=.018
64:7gal=28qt 28/60=.467
65: 8km=4.97mi 4.97x60=298.2

0.13
Step-by-step explanation:
Answer: We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
Step-by-step explanation:
Given : Significance level : 
Sample size : n= 52 , which is a large sample (n>30), so we use z-test.
By using z-value table,
Critical value: 
Sample mean : 
Standard deviation : 
The confidence interval for population means is given by :-
i.e. 
Now, the 95% confidence interval for the ppopulation mean = . (29.0813, 40.0187)
Hence, We are 95% confident that the mean SPF level of sunscreen used by all Cal Poly students is between 29.0813 and 40.0187.
