Answer:
y = 5x + 15
Step-by-step explanation:
the y intercept is 15 because that is the about that will initially be paid no matter how much or how little you swim, and the slope is five because the amount paid in all is determined by how much he swims. hope this helps :)
Answer:
First 25% 10 - 22.5
Next 25% 22.5 - 35
Third 25% 35 - 47.5
Last 25% 47.5 - 60
Step-by-step explanation:
First get the median of the entire data.
From the median, you split the data into two and find the median for both sections.
Finally, your smallest median is your first 25% and so on.
Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 4500
A = 6300
r = 6.75% = 6.75/100 = 0.0675
n = 2 because it was compounded 2 times in a year.
Therefore,.
6300 = 4500(1 + 0.0675/2)^2t
6300/4500 = (1 + 0.03375)^2t
1.4 = 1.03375^2t
Taking log of both sides of the equation, it becomes
Log 1.4 = 2t log 1.03375
0.1461 = 2t × 0.0144 = 0.0288t
t = 0.1461/0.0288
t = 5.1 years.
