I believe that there is 3 7/8 pounds of rocks left since 5lbs - 1 1/8lbs = 3 7/8lbs and 3 7/8lbs + 1 1/8lbs = 5lbs. Hope this helps and have a nice day!

A politician wants to estimate the proportion of constituents favoring a controversial piece of proposed legislation. suppose th
Volgvan

Answer:

We are given:

Confidence level = 99%. Therefore, the critical value at 0.01 significance level using the standard normal table is given below:

z_{\frac{0.01}{2}}=2.576

Margin of error is given in the question as:

E=0.05

Since the previous proportion is not given, therefore, we need to assume \hat{p} = 0.5

Therefore, the sample size is:

n=\hat{p}(1-\hat{p}) \left( \frac{z_{\frac{0.01}{2}} }{E} \right)

  =0.5(1-0.5) \left( \frac{2.576}{0.05} \right)

  =0.25 \times 51.52^2

  =663.6 \approx 664

Therefore, 664 sample observations are required.

<span>On an indifference curve, all bundles give the same amount of utility. (32,8) gives a utility of U(32,8)=32x8=256 If (4,y) is on the same indifference curve, then it must give the same utility. Hence, 256 = 4y y=64 64 bananas</span>

This is a simple exercise with rates.
You just have to divide the total profit of the store, that year, per the profit of the particular store.


[3.0479×10⁸ dollars] ÷ [2.102×10⁶ dollars] = 1,45 x 10²
