Answer:
(d) a matched pairs experiment.
Step-by-step explanation:
The correct answer is option D that is d) a matched pairs experiment.
A matched pair experiment is special case of randomize block design. This experiment can be used when the statement has two treatment conditions and subjects are grouped into pair based on some treatment. For each pair, random treatments are assigned to the subjects. It is an improvement over complete randomized design.
This is an experiment because a treatment (the MP3 players) was assigned to different members of the sample(the assembly line workers) randomly.

Answer:
A = $ 5,875.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
A = 5000(1 + (0.05 × 3.5)) = 5875
A = $ 5,875.00
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 5,000.00
at a rate of 5% per year
for 3.5 years is $ 5,875.00.
G(x) = x^2 - 6x + 14
g(x) = (x - 3)^2 + 5
