Answer:
the probability that exactly 30 of the 500 calculators IS 0.0495
Explanation:
Given data:
number of calculators n = 500,
percentage of defected calculators p = 0.05
From Normal approximation method;
Therefore probability is
P(X= 30) = P(29.5< X< 30.5) ( from continuous correction)
=0.0495 (from standard table of Z )
Answer:
<em>The monthly payments will be $353.12</em>
Explanation:
<u>Financing</u>
When a purchase is made at present value and the payment will be financed at a rate of interest i for n periods, the present value PV is
where R is the regular payment (usually monthly).
Solving for R
It's important to recall than only the unpaid amount goes financing, if some down-payment is made, it must be subtracted from the PV to be financed.
The present value of the car is 17,250 from which the buyer will make a 5% down-payment. It means that the real financing amount is
The rate of interest is
It also follows that n=54.
