Naomi deposited money into a savings account that is compounded quarterly at an interest rate of 6%. She thinks this quarterly r

Amiraneli [1.4K]

Answer:Yes, Naomi is incorrect.

Explanation: For explain this we can consider an example - Let us suppose Naomi deposited 100 rupees in her saving account at the rate 6% for 1 year .

Now, if the interest is quarterly then according to the formula

compound interest = $P(1+\frac{r/4}{100} )^{4n}$ -P where r is the rate annually and n is the number of years.

so CI= $100(1+\frac{6}{100})^4$ -100 ( here the rate is already given in quarterly)

CI= $100(1.06)^4$ -100= 1.26247696-100=26.247696 rupees=26(approx)

Now, if the compound interest is 1.25 per month then again from the formula-

CI= $P(1+\frac{r/12}{100})^{12n}$ -P

CI= $100(1+\frac{1.25}{100})^{12}$ -100= 100(1.16075452)-100=16.075452=16(approx)

Suppose that you draw two cards from a deck. After drawing the first card, you do not put the first card back in the deck. What

S_A_V [24]

Answer:

(B) 0.0588

Step-by-step explanation:

The probability is calculated as a division between the number of possibilities that satisfy a condition and the number of total possibilities. Then, the probability that the first card is diamonds is:

$P_1=\frac{13}{52}$

Because the deck has 52 cards and 13 of them are diamonds.

Then, if the first card was diamonds, the probability that the second card is also diamond is:

$P_2=\frac{12}{51}$

Because now, we just have 51 cards and 12 of them are diamonds.

Therefore, the probability that both cards are diamonds is calculated as a multiplication between $P_1$ and $P_2$ . This is:

$P=\frac{13}{52}*\frac{12}{51}=\frac{1}{17}=0.0588$
