Answer:

$9,220,000(0.888)^t

Step-by-step explanation:

Model this using the following formula:

Value = (Present Value)*(1 - rate of decay)^(number of years)

Here, Value after t years = $9,220,000(1 -0.112)^t

          Value after t years =  $9,220,000(0.888)^t

Find the missing variable for a triangle: a=48in2
Galina-37 [17]
Assuming that the given triangle is a right triangle where height and base are equal, we can solve for the missing variables. Let us review the given problem, the given is the total area since unit of "a" is inch squared. 

The formula for an area of a triangle is At = 1/2(bxh). We substitute the given value and assume that h=b.

Therefore, 48=1/2bh. To eliminate 1/2, we multiply both sides by 2. Then we have 96=bh. When b=h, we have b^2=96.

The missing variables are b=h=9.8.

Answer:

b = 16.5; 13; 9.5; 6; 2.5

Step-by-step explanation:

Subscribe the given information to get an Answer.

b = 39 / 2 - 3 = 16.5

b = 32 / 2 - 3 = 13

b = 25 / 2 - 3 = 9.5

b = 18 / 2 - 3 = 6

b = 11 / 2 - 3 = 2.5

Legalize Marijuana, Part II. As discussed in Exercise 6.12, the 2010 General Social Survey reported a sample where about 48% of
kvv77 [185]

Answer:

Around 2397 Americans must be surveyed to get a margin of error of 2%.

Step-by-step explanation:

We are given the following in the question:

Proportion of US residents who thinks marijuana should be made legal = 48%

\hat{p} = 0.48

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.48(1-0.48)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.48(1-0.48)}}{0.02}\\\\\sqrt{n}=48.96\\n = 2397.0816\approx 2397

Thus, around 2397 Americans must be surveyed to get a margin of error of 2%.
