Answer:
Time spend by Adelina at the tutoring session is 30 minutes.
Step-by-step explanation:
Given : In a tutoring session, of an hour was spent reviewing math problems and Adelina attended of the tutoring session.
We have to find the time Adelina spend at the tutoring session.
We know, 1 hour = 60 minutes.
Total time taken in tutoring session = minutes.
also, Adelina attended of the tutoring session that is of 40 minutes.
that is minutes.
Thus, time spend by Adelina at the tutoring session is 30 minutes.
Answer:
(B) 0.74 + or - 2.797 × 0.22/√25
Step-by-step explanation:
Confidence Interval = mean + or - t × sd/√n
mean = 0.74 hours
sd = 0.22 hours
n = 25
degree of freedom = n - 1 = 25 - 1 = 24
Confidence level = 99%
t-value corresponding to 24 degrees of freedom and 99% confidence level is 2.797
Confidence Interval = 0.74 + or - 2.797 × 0.22/√25
Answer:
See below in bold.
Step-by-step explanation:
Ship's vector:
Horizontal component = 30 cos 30 = 25.98.
Vertical component = 30 sin(-30) = -15.
So it is <25.98, -15).
The current's vector:
Horizontal component = 5 sin 20 = 1.71.
Vertical component = 5 cos 20 = 4.7.
So it is <1.71, 4.7>.
