How much money would you have if you invested $3000 at 6.25% annual interest, compounded daily for 2 years?

grandymaker [24]

Answer:

$A\simeq3399.41$

Step-by-step explanation:

The amount formula in compound interest is:

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

where:

P = principal amount

r = annual interest

n = number of compounding periods

t = number of years

We already know that:

P = $3000

$r = 6.25\% = \frac{6.25\%}{100\%}=0.0625$

t = 2

n = 365

Then,

$A=3000(1+\frac{0.0625}{365} )^{(365)(2)}\\\\A=3000(1+\frac{0.0625}{365} )^{730}\\\\A=3399.408982\\\\A\simeq3399.41$

John davis, a manager of a supermarket, wants to estimate the proportion of customers who use food stamps at his store. he has n

8_murik_8 [283]

Answer:

1509

Step-by-step explanation:

We know that, formula for number of samples is,

$n= \frac{z^2 \times p \times q}{SE^2}$

When nothing is given, we take $p=0.5$ and we know that $q = 1-p=0.5$ .

SE = 0.03 (the true proportion should remain withing 3%)

Putting the values we get,

$n= \frac{(2.33)^2 \times 0.5 \times 0.5}{(0.03)^2}$

$n= \frac{5.4289 \times 0.5 \times 0.5}{0.03 \times 0.03} \approx 1509$

Therefore, the sample required to estimate the true proportion to within 3 percentage points is 1509.

This is multiplying fractions and i have to show work

grandymaker [24]

To solve:

$\frac{2}{3}\times(-4\frac{1}{3})$

Let us convert the mixed fraction into fraction first,

$\frac{2}{3}\times(-\frac{13}{3})$

On simplification we get,

$-\frac{26}{9}$

Hence, the answer is,

$-\frac{26}{9}$
