Answer:

The probability that in a given day the store receives four or less bad checks is 0.70.

The probability that in a given day the store receives more than 3 bad checks is 0.50.

Step-by-step explanation:

The data provided shows the number of bad checks received by the management of a grocery store for a period of 200 days.

The probability distribution and the cumulative probability distribution are shown in the table attached below.

Let the number of bad checks received in a day be represented by <em>X</em>.

Compute the probability that in a given day the store receives four or less bad checks as follows:

P (X ≤ 4) = P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3) + P (X = 4)

              =0.04+0.06+0.10+0.30+0.20\\\\=0.70

Thus, the probability that in a given day the store receives four or less bad checks is 0.70.

Compute the probability that in a given day the store receives more than 3 bad checks as follows:

P (X > 3) = 1 - P (X ≤ 3)

              = 1 - [P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3)]

              =1-[0.04+0.06+0.10+0.30]\\=1-0.50\\=0.50

Thus, the probability that in a given day the store receives more than 3 bad checks is 0.50.

What is the total finance charge for a $4,250 loan at 13.25% interest compounded monthly for 24 months? ( I hate asking for help
antoniya [11.8K]
<span>There is a formula for a loan : A = P * r * ( r + 1 ) ^n / (( r + 1 ) ^n - 1 ), where P is the loan and A is the monthly payment. So P = $4,250 and r = 0.1325 : 12 = 0.011. ( 13.25 % = 0.1325 and we divide it by 12, because the interest is compounded monthly ). A = 4,250 * 0.011 * 1.011^(24) / ( 1.011^(24) - 1 ) = 4,250 * 0.11 * 1.3 / 0.3 = 4,250 * 0.0477; A = $202.55. Finally we have to multiply this sum by 24 : the total finance charge: $202.55 * 24 = $ 4,861.20. Answer: D ) $4,861.20 </span>
