A person invests 9000 dollars in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long

il63 [147K]

Answer:

$7.4\ years$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=?\ years\\ P=\$9,000\\ r=0.06\\n=12\\ A=\$14,000$

substitute in the formula above

$14,000=9,000(1+\frac{0.06}{12})^{12t}$

$(14/9)=(1.005)^{12t}$

Apply log both sides

$log(14/9)=(12t)log(1.005)$

$t=log(14/9)/[(12)log(1.005)]$

$t=7.4\ years$

The angle of deperession of aPt A, as measured form the top of

lara [203]

Answer:B

Step-by-step explanation:

Given

Height of building $h=30\ m$

Angle of depression $\theta =45^{\circ}$

Suppose distance of Point A from base of building be $x$

From diagram we can write

$\Rightarrow \tan \theta =\dfrac{h}{x}$

$\Rightarrow \tan (45^{\circ})=\dfrac{30}{x}$

$\Rightarrow 1=\dfrac{30}{x}$

$\Rightarrow x=30\ m$

So, point A is $30\ m$ from base of building

Eric throws a biased coin 10 times. He gets 3 tails. Sue throw the same coin 50 times. She gets 20 tails. Aadi is going to throw

iren2701 [21]

Answer:

(1) The correct option is (A).

(2) The probability that Aadi will get Tails is $\frac{2}{5}$ .

Step-by-step explanation:

It is provided that:

Eric throws a biased coin 10 times. He gets 3 tails.
Sue throw the same coin 50 times. She gets 20 tails.

The probability of tail in both cases is:

$P(\text{Tail})=\frac{3}{10}$
$P(\text{Tail})=\frac{20}{50}=\frac{2}{5}$

(1)

According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

In this case we need to compute the proportion of tails.

Then according to the Central limit theorem, Sue's estimate is best because she throws it n = 50 > 30 times.

Thus, the correct option is (A).

(2)

As explained in the first part that Sue's estimate is best for getting a tail, the probability that Aadi will get Tails when he tosses the coin once is:

$P(\text{Tail})=\frac{20}{50}=\frac{2}{5}$

Thus, the probability that Aadi will get Tails is $\frac{2}{5}$ .
