These are not division problems...." the product " means multiply

5 3/4 * 3/2 .....turn mixed number into improper fraction, then multiply
23/4 * 3/2 =
(24 * 3) / (4 * 2) =
72/8 which equals 9 <==
==============
1/3 * 1/4 =
(1 * 1) / (3 * 4) =
1/12 <==
=============
2/1 * 5/9 =
(2 * 5) / (1 * 9) =
10/9 or 1 1/9 <===

Step-by-step explanation:

Let the price of the house when it is being sold be = x

The Annual return received from the fund after a year that house is being sold is : A - P

where ;

P = current market price

A = price after one year

A is given by the formula:

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

where ; P = x

r = 8.5% = 0.085

n = 12

t = 1

$A= x(1+\frac{0.085}{2})^{12*1}$

$A= x(1.00708333)^{12}$

A = 1.08839 x

The annual return is A - P = 1.08839 x - x

= 0.08839x

However, the house should be sold when this return is equivalent to the annual increase in value of the house

∴ 0.08839x = 31250

$x = \frac{31250}{0.08839} \\ \\ x = 353546.78$

Thus , the current price (x) = $353546.78

Profit till that time = Current price - Initial Price

= (353546.78- 250000)$

= $103546.78

The time taken for this much profit to accumulate = $\frac{Total \ profit}{Annual \ profit}$

= $\frac{103546.78}{31250}$

= 3.3135

≅ 3.3 years ( to one decimal place)

SpyIntel [72]

Answer:

A point estimate for the true population proportion is $\hat{p} = 0.83$ and the 90% confidence interval is (0.8025, 0.8575)

Step-by-step explanation:

We have a large sample of people of size n = 506. Let X be the random variable that represents the number of adults who feel that education is one of the top issues facing California. We are interested in the unknown true proportion p of adults who feel that education is one of the top issues facing California. A point estimate for the true population proportion is given by $\hat{p}$ = X/n = 418/506 = 0.83, the standard deviation is given by $\sigma_{\hat{p}} = \sqrt{p(1-p)/n}\approx\sqrt{\hat{p}(1-\hat{p})/n} = \sqrt{(0.83)(0.17)/506} = 0.0167$ . Therefore, the 90% confidence interval for the true population proportion is $\hat{p}\pm z_{0.1/2}\sqrt{\hat{p}(1-\hat{p})/n}$ , i.e., $0.83\pm z_{0.05}0.0167$ , i.e., $0.83\pm (1.6448)(0.0167)$ , (0.8025, 0.8575).
