Using the z-distribution, it is found that the 98% confidence interval for the difference in the proportion of apples with blemishes is of (-0.1055, 0.2655).

The sample proportions, and standard error for each sample, are given as follows:

[tex]p_G = \frac{48}{75} = 0.64[/tex]

[tex]s_G = \sqrt{\frac{0.64(0.36)}{75}} = 0.0554[/tex]

[tex]p_R = \frac{42}{75} = 0.56[/tex]

[tex]s_R = \sqrt{\frac{0.56(0.44)}{75}} = 0.0573[/tex]

The distribution of differences has mean and standard error given by:

[tex]p = p_G - p_R = 0.64 - 0.56 = 0.08[/tex]

[tex]s = \sqrt{s_G^2 + s_R^2} = \sqrt{0.0554^2 + 0.0573^2} = 0.0797[/tex]

The confidence interval is given by:

[tex]p \pm zs[/tex]

z is the critical value. We have a 98% confidence level, hence, using a z-distribution calculator, it is of z = 2.327.

The lower limit of this interval is:

[tex]\pi - zs = 0.08 - 2.327(0.0797) = -0.1055[/tex]

The upper limit of this interval is:

Explanation:

If donations are received from 45 people, each one should contribute 75 dollars to get the total necessary to build the playground.

To calculate how much each donor must contribute, we must take into account the total money that it is worth to build the park. To do this, we perform the following operation:

25 × $135 = $3,375

So if 45 people donated, we need to divide this value by that number of people as shown below:

$3375 ÷ 45 = $75

Note: This question is incomplete because there are some information missing. Here is the missing information:

A neighborhood group wants to build a new playground using donations from residents. The amount needed from each donor varies inversely to the number of people donating.

The correct statement is the customer would pay $19,324 for Car S.

A discount is when the price of an item is reduced by a certain amount or percentage. A discount reduces the cost of an item. A rebate is a form of cash back on the price of an item. A rebate reduces the cost of an item.

Price of Car R = (100% - 5%) x $25,340

95% x $25,340

0.95 x $25,340

= $24,073

$24,073 - $3,500 = $20,573

Price of Car S = (100% - 10%) x $22,860

90% x  $22,860

$22,860 x 0.9

= $20,574

$20,574 - $1,250 = $19,324

Answer:

A, B, and E are the correct options.

Explanation:

Two disjoint pairs of consecutive sides are congruent by definition - QP≅QR and QR is not congruent to RS (one side can’t be used in both pairs);

One diagonal (segment QS, the main diagonal) is the perpendicular bisector of the other diagonal (segment PR, the cross diagonal), so PM≅MR;

The opposite angles at the endpoints of the cross diagonal are congruent, thus ∠QPS≅∠QRS.

∠PQR is not congruent to ∠PSR, because they are not angles at the endpoints of the cross diagonal.

Therefore, A, B, and E are the correct options.

The level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

The volume of the spherical tank is calculated by using the following formula as shown below;

[tex]V = \frac{4}{3} \pi r^3= \frac{4}{3} \pi (\frac{d}{2} )^3= \frac{4}{3} \pi \frac{d^3}{8} = \frac{1}{6} \pi d^3[/tex]

The level lines on the tank showing the depths of different capacities is calculated as follows;

[tex](\frac{1}{6} \pi d^3 )k = V\\\\k = \frac{V}{d^3} \\\\\frac{V_1}{d_1^3} = \frac{V_2}{d_2^3}\\\\d_2 = \sqrt[3]{\frac{V_2d_1^3}{V_1} }\\\\for \ 10,000 \ L\\\\d_2 = \sqrt[3]{\frac{10,000\times 4^3}{33,500} }\\\\d_2 = 2.65 \ m\\\\for \ 20,000 L\\\\d_3 = \sqrt[3]{\frac{20,000\times 4^3}{33,500} }\\\\d_3 = 3.36\ m\\\\d_4 = \sqrt[3]{\frac{30,000\times 4^3}{33,500} }\\\\d_4 = 3.85 \ m[/tex]

Thus, the level line at 10,000 liters is 2.65 m, the level line at 20,000 liters is 3.36 m and the level line at 30,000 liters is 3.85 m.

The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

Given data :

Diameter of tank ( d ) = 4 m

1 cm³ = 1000 l

The volume of a spherical tank can be calculated as

V = [tex]\frac{4}{3}\pi r^3 = \frac{1}{6}\pi d^3[/tex]

Next step : calculate the level lines at various capacities

applying equation above

V = [tex](\frac{1}{6} \pi d^3)k[/tex]

where k = v / d³

therefore : di = [tex]\sqrt[3]{\frac{Vid^3}{V_{1} } }[/tex]  ------- ( 1 )

where : di = level line , Vi = volume of tank , V1 = capacity of tank = 33500

             d = diameter of tank

Applying equation ( 1 )

   level line ( di ) = 2.65 m

 level line ( di ) = 3.36 m

  level line ( di ) = 3.85 m

Hence we can conclude that The level line for 10000 l is : 2.65 m , The level line for 20000 l is : 3.36 m . and The level line for 30000 l is : 3.85 m

Considering the reaction stoichiometry and the definition of limiting reagent, the percent yield for the reaction is 42.86%.

The balanced reaction is:

2 NO + O₂ → 2 NO₂

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.

To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) and use a simple rule of three as follows: if by stoichiometry 1 mole of O₂ reacts with 2 moles of NO, if 5 moles of O₂ react how much moles of NO will be needed?

[tex]moles of NO=\frac{5 moles of O_{2} x2 moles of NO}{1 mole of O_{2} }[/tex]

moles of NO= 10 moles

But 10 moles of NO are not available, 7 moles are available. Since you have less moles than you need to react with 5 moles of O₂, NO will be the limiting reagent.

Then you can apply the following rule of three, considering the limiting reagent: if by stoichiometry 2 moles of NO produce 2 moles of NO₂, 7 moles of NO will produce how many moles of NO₂?

[tex]amount of moles of NO_{2} =\frac{7 moles of NOx2 moles of NO_{2}}{2 moles of NO}[/tex]

amount of moles of NO₂= 7 moles

So, the amount of moles of NO₂ produced is 7 moles.

The maximum amount of product that can be produced is called the theoretical yield.

Percent yield is the amount of product actually obtained from a reaction and determines the efficiency of the reaction.

The expression for percent yield is:

[tex]Percent yield=\frac{actual yield}{theoretical yield}x100[/tex]

To determine the percent yield for the reaction in this case, you know:

Replacing in the definition of percent yield:

[tex]Percent yield=\frac{3 moles}{7 moles}x100[/tex]

Percent yield= 42.86%

Finally, the percent yield for the reaction is 42.86%.
