(i) Monthly installment is $21.53 approximately.

(ii) Total amount man has to pay is $3716.8

(iii) Extra money he had to pay for buying the computer on hire is $516.8

Given,

Initial price of the computer(p) = $3200

Down payment = $480

Time period = 2 yrs

rate percent = 9.5%

(i) Monthly installment = ?

monthly installment =(capital amount × interest rate)/time in months

down payment to be paid = 3200 ₋ 480

= 2720

therefore, monthly payment = 2720 × 9.5 × 1/ 12

= $21.53

(ii) Total amount man has to pay = ?

= down payment ₊ remaining amount ₊ (remaining amount × t × r)

= 480 ₊ 2720 ₊ 2720 × 9.5 × 2

= $3716.8

(iii) If he buys the computer on hire then how much more he has to pay = ?

= total amount ₋ initial cost

= 3716.8 ₋ 3200

= $516.8

Hence the man has to pay $21.23 as a monthly installment, $3716.8 as a total cost of the computer system and $516.8 as an extra amount if he buys it on hire.

Theoretical probability is the probability that an event occurs when all of the outcomes of the experiment are equally likely.

MA_775_DIABLO [31]

1. The probability that we select a red marble is 1/3.

We found this out by taking the amount of red marbles there are and the total amount of marbles. The total amount of marbles is 18 and there are red marbles. So, it would become 6 out of 18 or 6/18. Then, we simplify 6/18 to the simplest form. The greatest common factor of both of those numbers is 6. Lastly, we divide each of them by 6 to get the simplest form.

6/18 = (6/6)/(18/6)

(6/6)/(18/6) = 1/3

So, therefore, the theoretical probability of picking a red marble is 1/3.

2. The probability that we select a blue marble is 2/3.

We can find this out by taking the amount of blue marbles there are and the total amount of marbles. We know that the total amount of marble is 18 and there are 12 blue marbles. So, we simply get the GCF (greatest common factor) and divide them by it.

Greatest Common Factor of 12 and 18 = 6

12/18 = (12/6)/(18/6)

(12/6)/(18/6) = 2/3

Thus, the theoretical probability of picking a blue marble is 2/3.

Adult red wolves vary in length from 137.16 cm to 168.64 cm. Estimate the difference in length between the longest and shortest

zhannawk [14.2K]

Answer:

As per the statement:

Adult red wolves vary in length from 137.16 cm to 168.64 cm.

To find the difference in length between the longest and shortest of these wolves.

Longest length of wolves = 168.64 cm

Shortest length of wolves= 137.16 cm

Then;

$\text{Difference of the length between the longest and shortest of these wolves}$ = $\text{Length of longest wolves} -\text{Length of shortest wolves}$

Substitute the given values we have;

$\text{Difference of the length between the longest and shortest of these wolves}$ = 168.64 - 137.16 = 31.48 cm

therefore, the difference in length between the longest and shortest of these wolves is 31.48 cm
