Answer:

percentage error = 7.14%

Step-by-step explanation:

Hank's speedometer reads 60 miles per hour, but during a road test he finds the he was actually driving 56 mph.

estimated/ read value = 60 miles per hour

actual value/correct value = 56 miles per hour

error = estimated or read value - correct value/actual value

error = 60 - 56 = 4 mph

percentage error = error / correct value × 100

percentage error = 4/56 × 100

percentage error = 400/56

percentage error = 7.1428571429%

percentage error = 7.14%

A principal of $3400 is invested at 7.75% interest, compounded annually. How much will the investment be worth after 15 years? U
DENIUS [597]
A = $ value after 15 years
P = principal (initial deposit)
r = annual % rate
n = # of times interest compounds per year
t = # of years the money is invested

Formula:
A = P (1 + r/n)^(nt)

A= $3400(1+ 0.0775/1) ^(1*15)
A= 3400(1.0775)^15
A= 3400(3.0637913274)
A= $10,417 investment after 15 years

Hope this helps! :)
