Answer:

Step-by-step explanation:

To convert from liters per day to gallons per week, we need to use the conversion factors for these units. One gallon is equivalent to 3.785 liters, and one week is equivalent to 7 days.

We can use these conversion factors to write the following conversion equation:

1 gallon/week = (3.785 liters/gallon) / (7 days/week)

We can then use this equation to convert 400 liters per day to gallons per week by multiplying the number of liters per day by the conversion factor. This gives us:

400 liters/day * (1 gallon/week) / (3.785 liters/gallon) / (7 days/week)

We can simplify this expression by canceling out the units that appear on both the numerator and denominator. This gives us:

400 / 3.785 / 7 = 105.66

Therefore, 400 liters per day is equivalent to 105.66 gallons per week

The ratios that could be the lengths of the two legs in a 30-60-90 triangle are √3:3 (option E) and 12√3 (option D).

In a 30-60-90 triangle, the angles are in the ratio of 1:2:3. The sides of this triangle are in a specific ratio that is consistent for all triangles with these angles. Let's analyze the given options to determine which ones could be the ratio between the lengths of the two legs.

A. √2:√2

The ratio √2:√2 simplifies to 1:1, which is not the correct ratio for a 30-60-90 triangle. Therefore, option A is not applicable.

B. 15

This is a specific value and not a ratio. Therefore, option B is not applicable.

C. √√√√5

The expression √√√√5 is not a well-defined mathematical operation. Therefore, option C is not applicable.

D. 12√3

This is the correct ratio for a 30-60-90 triangle. The ratio of the longer leg to the shorter leg is √3:1, which simplifies to √3:3. Therefore, option D is applicable.

E. √3:3

This is the correct ratio for a 30-60-90 triangle. The ratio of the longer leg to the shorter leg is √3:1, which is equivalent to √3:3. Therefore, option E is applicable.

F. √2:√5

This ratio does not match the ratio of the sides in a 30-60-90 triangle. Therefore, option F is not applicable. So, the correct option is D. 1 √2.

The given double integral is ∫ ∫ (x² + y²)dx dy, and we need to evaluate it over the region in the positive quadrant where x+y≤1.

To evaluate this double integral, we can first determine the limits of integration for both x and y based on the given region. In the positive quadrant, x and y both range from 0 to 1.

Now, integrating the inner integral with respect to x, we get:

∫ (x² + y²)dx = (1/3)x³ + y²x + C1,

where C1 is the constant of integration.

Next, we integrate the resulting expression with respect to y:

∫ [(1/3)x³ + y²x + C1] dy = (1/3)x³y + (1/3)y³x + C1y + C2,

where C2 is another constant of integration.

Finally, we evaluate this double integral over the given region by substituting the limits of integration:

∫∫ (x² + y²)dx dy = ∫[0 to 1] ∫[0 to 1-x] (x² + y²)dy dx.

Performing the integration, we can find the numerical value of the double integral within the given region.

Answer:

∠ ABD = 20°

Step-by-step explanation:

since BD bisects ∠ ABC , then

∠ ABD = ∠ CBD ( substitute values )

3x - 1 = 34 - 2x ( add 2x to both sides )

5x - 1 = 34 ( add 1 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7

Then

∠ ABD = 3x - 1 = 3(7) - 1 = 21 - 1 = 20°

The history threat is never relevant to a repeated-measures design.

The threat to internal validity that is never relevant to a repeated-measures design is the history threat.
In a repeated-measures design, the same participants are measured multiple times under different conditions or treatments. This design eliminates the need for random assignment of participants to different groups, as each participant serves as their own control.
The history threat refers to external events or influences that occur during the course of an experiment and can affect the results. For example, if a study on the effects of a new teaching method is conducted over a semester, a history threat could be the introduction of a new curriculum that all students receive halfway through the study. This external event could confound the results and make it difficult to determine if the observed changes are due to the teaching method or the new curriculum.
However, in a repeated-measures design, the participants serve as their own control, and any external events or influences that occur will affect all conditions or treatments equally. This means that any history threat is the same across all measurements, making it irrelevant to the design.
Therefore, the history threat is never relevant to a repeated-measures design.

The height of the rectangular prism with a volume of 132.5cm³ and a base area of 25cm² is 5.3cm.

To find the height of the rectangular prism, we can use the formula for the volume of a rectangular prism, which is V = lwh (where l is the length, w is the width, and h is the height).

We are given that the volume is 132.5cm³ and the base area is 25cm². We can use the base area to find the length and width of the prism.

Since the base area is lw = 25cm², we can choose any two factors of 25 to be the length and width. Let's say the length is 5cm and the width is 5cm.

Now we can use the formula for the volume to find the height:

V = lwh
132.5cm³ = (5cm)(5cm)(h)
132.5cm³ = 25cm²(h)
h = 132.5cm³/25cm²
h = 5.3cm

Therefore, the height of the rectangular prism is 5.3cm.

C. n = 90; p = 0.8

Step-by-step explanation:

According to the Central Limit Theorem, the distribution of the sample means will be approximately normally distributed when the sample size, 'n', is equal to or larger than 30, and the shape of sample distribution of sample proportions with a population proportion, 'p' is normal IF n·p ≥ 10 and n·(1 - p) ≥ 10

Analyzing  the given options, we have;

A. n = 45, p = 0.8

∴ n·p = 45 × 0.8 = 36 > 10

n·(1 - p) = 45 × (1 - 0.8) = 9 < 10

Given that for n = 45, p = 0.8, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution

B. n = 90, p = 0.9

∴ n·p = 90 × 0.9 = 81 > 10

n·(1 - p) = 90 × (1 - 0.9) = 9 < 10

Given that for n = 90, p = 0.9, n·(1 - p) = 9  < 10, a normal distribution can not be used to approximate the sampling distribution

C. n = 90, p = 0.8

∴ n·p = 90 × 0.8 = 72 > 10

n·(1 - p) = 90 × (1 - 0.8) = 18 > 10

Given that for n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution

D. n = 45, p = 0.9

∴ n·p = 45 × 0.9 = 40.5 > 10

n·(1 - p) = 45 × (1 - 0.9) = 4.5 < 10

Given that for n = 45, p = 0.9, n·(1 - p) = 4.5 < 10, a normal distribution can not be used to approximate the sampling distribution

A sampling distribution Normal Curve

45 × (1 - 0.8) = 9

90 × (1 - 0.9) = 9

90 × (1 - 0.8) = 18

45 × (1 - 0.9) = 4.5

Now we will investigate the shape of the sampling distribution of sample means. When we were discussing the sampling distribution of sample proportions, we said that this distribution is approximately normal if np ≥ 10 and n(1 – p) ≥ 10. In other words

Therefore;

A normal curve can be used to approximate the sampling distribution of only option C. n = 90; p = 0.8

When we substitute these values into the equation, we get the required rate of return on AA Corporation's stock as 8.4%.

Required return on stock = Risk-free rate + Beta x (Market return - Risk-free rate)

Required return on stock = 4% + 0.8 x (12% - 4%)

Required return on stock = 8.4%

The required rate of return on AA Corporation's stock is 8.4%. To calculate this, we use the formula required return on stock = risk-free rate + beta x (market return - risk-free rate). In this equation, the risk-free rate is 4%, the beta of AA Corporation's stock is 0.8 and the expected return on the market is 12%. The risk-free rate remains constant, the beta of the stock gives an indication of its volatility and the market return reflects the overall performance of the market. When we substitute these values into the equation, we get the required rate of return on AA Corporation's stock as 8.4%.

Answer:

The number of clay flower pots = x = 19

The number of ceramic flower pots = y = 16

Step-by-step explanation:

Let

The number of clay flower pots = x

The number of ceramic flower pots = y

Tara bought 35 flower pots

= x + y = 35

x = 35 - y

The gardening store sells clay flower pots, which hold 2 litres of dirt, and ceramic flower pots, which hold 7 litres. Tara bought 35 flower pots, which will hold a total of 150 litres of dirt.

Hence:

2x + 7y = 150.... Equation 2

Substitute 35 - y for x in Equation 2

2 (35 - y) + 7y = 150

70 - 2y + 7y = 150

-2y + 7y = 150 - 70

5y = 80

y = 80/5

y = 16 flower pots

x = 35 - y

x = 35 - 16

x = 19 flower pots

The number of clay flower pots = x = 19
