If I'm right the principal amount is $1,000 and the interest(if $1,550) is $550 in the transaction.
The expression 8(-3) represents the recession of the coastline after 8 years if the coastline recedes 3 centimeters each year. 8(-3)=-24. So, the coastline's new position is 24 centimeters farther inland than it was 8 years ago.
answer= 24
If you're doing it mentally, you should find a common factor between the nominator and denominator that also multiplies to make 100.
So here,
Divide top and bottom by 6.
That gives you: 3/4
3/4 is 75%
3 x 25 = 75
Answer:
3.113, 4.507
Step-by-step explanation:
From the given values:
Mean = 3.81
Standard deviation = 1.74
Therefore
M = √(1.72/18) = 0.4
μ = M ± t(sM)
μ = 3.81 ± 1.74*0.4
μ = 3.81 ± 0.697
Recall that the mean is estimated at 90% confidence level,
Hence,
= 90% CI [3.113, 4.507]
