Answer:

15N + 21

Step-by-step explanation:

We are given that,

Amount of carpet bought by Peter = N meter²

The cost per meter square of the carpet = $15

So, the cost of 'N' meter square of carpet = 15N dollars.

Also, the delivery charge for the carpet = $21

Thus, the total cost of the carpet is given by,

Total cost = Cost per square meter + Delivery charge

i.e. Total cost = 15N + 21 (in dollars).

Hence, the expression representing the cost in dollars is '15N + 21'.

Answer:

The sample space would be infinite

{HH, TTTHH, TTTTHH, TTTTTTTHH.......................}

1/8

Step-by-step explanation:

The sample space would be infinite

{HH, TTTHH, TTTTHH, TTTTTTTHH.......................}.

This is because the number of times the coin would be flipped is not specified. So, you can keep flipping the coin forever.

If the coin is tossed four times then the sample space would be

{HHHH HTHH THHH HTHT

HHHT HTTH TTHH THTH

HHTT HHTH TTTH THHT

HTTT TTTT TTHT THTT}

HTHH and TTHH are the only two cases where two consecutive tosses will result in two heads

Probability that the coin will be tossed four times is 2/16 = 1/8

Find the value of annuity if the periodic deposit is $400 at 4% compounded monthly for 18 years
vlada-n [284]

Answer:

~820.8$

Step-by-step explanation:

The total money (M) after 18 years could be calculated by:

M = principal x (1 + rate)^time

with

principal = 400$

rate = 4% compounded monthly = 0.04/12

time = 18 years = 18 x 12 = 216 months (because of compounded monthly rate)

=> M = 400 x (1 + 0.04/12)^216 = ~820.8$
