2. Cathy wants to buy a new dishwasher for her apartment. Cathy does some research online,
She finds that the mean repair cost of 20 Whirlpool machines is $211 with a standard deviation
of $23. She finds that the mean repair cost of 29 Samsung machines is $239 with a standard
deviation of $22. Construct and interpret a 98 percent confidence interval for the difference in
mean repair costs between the Whirlpool and Samsung dishwashers,

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

c. side angle side. u shares the same sides

p = 6s
