Answer:

she swam 63 minutes more than in the first

Step-by-step explanation:

first week only = 142 minutes

total week = 347

second week only = 347 - 142 = 205 minutes

205 - 142 = 63 minutes

Answer:

Both prices should be set to #25.

The maximum revenue is #4375

Step-by-step explanation:

Given

[tex]q_1 = 150-2p_1-p_2[/tex]

[tex]q_2 = 200-p_1-3p_2[/tex]

Start by calculating the total revenue (R):

[tex]R = p_1q_1 + p_2q_2[/tex]

[tex]R = p_1(150-2p_1-p_2) + p_2(200-p_1-3p_2)[/tex]

[tex]R = 150p_1-2p_1^2-p_1p_2 + 200p_2-p_1p_2-3p_2^2[/tex]

Collect and solve like terms

[tex]R = 150p_1+ 200p_2-2p_1^2-2p_1p_2 -3p_2^2[/tex]

Differentiate with respect to pi and to p2, respectively

[tex]\frac{dR}{dp_1} = 150 -4p_1 - 2p_2[/tex]

[tex]\frac{dR}{dp_2} = 200 -2p_1 - 6p_2[/tex]

Equate both to 0, to get the critical point

[tex]150 -4p_1 - 2p_2 = 0[/tex]

[tex]200 -2p_1 - 6p_2 = 0[/tex]

Solve for p1 in [tex]150 -4p_1 - 2p_2 = 0[/tex]

[tex]4p_1 = 150 - 2p_2[/tex]

[tex]p_1 = 37.5 - 0.5p_2[/tex]

Substitute [tex]p_1 = 37.5 - 0.5p_2[/tex] in [tex]200 -2p_1 - 6p_2 = 0[/tex]

[tex]200 - 2(37.5 - 0.5p_2) - 6p_2 = 0[/tex]

[tex]200 - 75 - p_2 - 6p_2 = 0[/tex]

[tex]125 - 7p_2 = 0[/tex]

[tex]-7p_2 =-125[/tex]

[tex]p_2 = 25[/tex]

Substitute [tex]p_2 = 25[/tex] in [tex]p_1 = 37.5 - 0.5p_2[/tex]

[tex]p_1 = 37.5 - 0.5 * 25[/tex]

[tex]p_1 = 37.5 - 12.5[/tex]

[tex]p_1 = 25[/tex]

So, we have:

[tex]p_1 = p_2 = 25[/tex]

This implies that the prices should be set to #25.

The maximum possible revenue is:

[tex]R = 150p_1+ 200p_2-2p_1^2-2p_1p_2 -3p_2^2[/tex]

[tex]R = 150 * 25 + 200 * 25 -2 * 25^2 - 2 * 25 * 25 - 3 * 25^2[/tex]

[tex]R = 4375[/tex]

The maximum revenue is #4375

The maximum possible revenue is 4375.

From the information given, the following can be deduced:

Q₁ = 150 - 2P₁ - P₂

Q₁ = 150 - 2P₁ - P₂Q₂ = 200 - P₁ - 3P₂

The total revenue will be:

R = P₁Q₁+ P₂Q₂

R = P₁(150 - 2P₁ - P₂) + P₂(200 - P₁ - 3P₂)

R = 150P₁ + 200P₂ - 2P₁² - 2P₁P₂ - 3P₂²

To maximize, differentiate it in both the direction of P₁ and P₂.

d/dP₁ = 150 - 4P₁ - 2P₂

d/dP₂ = 200 - 2P₁ - 6P₂.

Solving for P₁ goes thus:

4P₁ = 150 - 2P₂

Divide through by 4

P₁ = 37.5 - 0.5P₂

Since 200 - 2P₁ - 6P₂ = 0

200 - 2(37.5 - 0.5P₂) - 6P₂ = 0.

P₂ = 25

Therefore, the revenue will be:

= 150P₁ + 200P₂ - 2P₁² - 2P₁P₂ - 3P₂²

= (150 × 25) + (200 × 25) - (2 × 25 × 25) - (3 × 25²)

= 4375

In conclusion, the revenue is 4375.

Answer:

0.4 = 40% probability the marble is even numbered given the marble is yellow.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

There are 5 yellow marbles, which means that the number of total outcomes is [tex]T = 5[/tex]

2 of those(2 or 4) are even numbered, which means that the number of desired outcomes is [tex]D = 2[/tex]

Find the probability the marble is even numbered given the marble is yellow.

[tex]p = \frac{D}{T} = \frac{2}{5} = 0.4[/tex]

0.4 = 40% probability the marble is even numbered given the marble is yellow.

Answer:

If the circle's radius is 3, then its area is 28.27 cm.

Step-by-step explanation:

A circle's area is equal to (A = π r²).

Plug in the radius for R, and your equation should look like the following:

A = π3²

According to PEMDAS, you have to do the exponent first.

Do 3 squared, THEN multiply what you get by pi.

Then what you get should be your area.

Answer:

the standard deviation of the residuals

Step-by-step explanation:

The removal of the professional football players will cause the correlation, and consequently r2 to become closer to 0 due to the fact that the high school athletes tend to show no association between the number of energy drinks consumed and the number of pull ups that can be done. The slope of the regression line will also be nearly 0 without the professional football players. The standard deviation of the residuals, however, will increase without the presence of the professional football players because the remaining scatter about the new regression line will be greater due to the loss of the 4 professional football players which all had small residuals.

The option that will increase if the football players were removed from the data set is the standard deviation of the residuals

It should be noted that standard deviation simply means the difference between the observed data and the predicted values.

In this case, the standard deviation of the residual will increase if the football players were removed from the data set as the removal of the professional football players will cause the correlation.

7.7829

95% of the confidence interval for the true average proportional limit stress of all such joints

(7.7829, 9.3171)

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 12

Mean of the sample = 8.55

The standard deviation of the sample (S) = 0.76

Step(ii):-

95% of the confidence interval is determined by

[tex](x^{-} - t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } , x^{-} + t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} })[/tex]

Degrees of freedom = n-1 = 12-1 = 11

t₀.₀₂₅ = 3.4966

[tex](8.55 - 3.4966\frac{0.76}{\sqrt{12} } , 8.55 + 3.4966 \frac{0.76}{\sqrt{12} })[/tex]

(8.55 - 0.7671 , 8.55+0.7671)
