The researchers used a sample of mice in a maze experiment to study learned behavior. They timed each mouse on its first run through the maze and again on its tenth run through the maze, recording the difference in times for each mouse.

The maze experiment is a common method used by researchers to study the learned behavior of animals, including mice. In this experiment, a maze is set up with food placed at the end to motivate the mouse to find its way through the maze. The researchers time the mouse on its first run through the maze to establish a baseline for the mouse's performance. They then repeat the experiment by timing the mouse on its tenth run through the maze to see if the mouse has learned and improved its performance. By subtracting the time of the first run from the time of the tenth run, the researchers can measure the difference in time and assess how much the mouse has learned.

The difference in time between the first and tenth run can be used as a measure of learning, and statistical analysis can be applied to identify significant changes in the mouse's performance. This type of experiment can be useful for studying the effects of different variables on learning, such as different training methods or drug treatments. The maze experiment can also be adapted to study other aspects of animal behavior, such as memory and decision-making.

Answer:

Graph under 10, only a bit, (0,9) because y = 9

Step-by-step explanation:

The volume of the given solid, with the boundaries, is given as follows:

661.5 cubic units.

The volume of the solid is obtained using a double integral.

The equation for the solid is given as follows:

7x + 9y + z = 63.

z = 63 - 7x - 9y.

The coordinate planes bound the plane, hence:

Hence the double integral that is used to obtain the volume of the solid is given as follows:

\(V = \int_{0}^{9}\int_{0}^{7 - \frac{7x}{9}} 63 - 7x - 9y dydx\)

The inner integral is given as follows:

\(I = \int_{0}^{7 - \frac{7x}{9}} 63 - 7x - 9y dy\)

Which, applying the Fundamental Theorem of Calculus, has the result given as follows:

\(I = -98x + \frac{49x^2}{9} - \frac{(7x + 63)^2}{18} + 441\)

Then the volume of the solid is given by the outer integral as follows:

\(V = \int_{0}^{9} \left(-98x + \frac{49x^2}{9} - \frac{(7x + 63)^2}{18} + 441\right) dx\)

Which has a numeric value of:

661.5 cubic units.

The median of the following set of numbers  (18, 26, 29, 18, 44) is 26. The correct option to this question is option A

To find median of the following sequence (18, 26, 29, 18, 44) we will arrange them in ascending order

                            18 , 18 , 26 , 29 , 44   . . . . . .  . . . .(1)

Since the number of terms is odd we will apply the formula

                     Median  = \(\frac{(n+1)}{2} th\) term . . . . . . .(2)

       Here n = number of terms

As per question the n = 5

Therefore putting in equation 2 we get

                      Median = \(\frac{(5+1)}{2} th\) term

                      Median = \(\frac{6}{2} th \\\)  term

                      Median = 3 term

Hence the third term from the sequence ( shown in 1 ) we get the median that is 26

Hence the median of the following set of numbers (18, 26, 29, 18, 44) is 26 .

Chanas distance from the starting line at a time when she is farther than Josiah.

The blanks are filled as follows

Step one

Equation 2x + y = 18 Isolate y,

y = 18 - 2x

Step Two:

Equation 8x - y = 22, Plug in for y

8x - (18 - 2x) = 22

Step Three: Solve for x by isolating it

8x - (18 - 2x) = 22

8x - 18 + 2x = 22

8x + 2x = 22 + 18

10x = 40

x = 4

Step Four: Plug what x equals into your answer for step one and solve

y = 18 - 2x

y = 18 - 2(4)

y = 18 - 8

y = 10

To find the z-value that corresponds to a certain percentile for a standard normal distribution, we can use a table of standard normal probabilities or a calculator.
Percentile:In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition). Percentiles are expressed in the same unit of measurement as the input scores, not in percent; for example, if the scores refer to human weight, the corresponding percentiles will be expressed in kilograms or pounds.
a) To find the z-value that corresponds to the 30th percentile, we first need to convert the percentile to a percentage. The 30th percentile corresponds to the bottom 30% of the distribution.

Using a table or calculator, we can find that the z-value that corresponds to the 30th percentile is approximately -0.52. This means that 30% of the area under the standard normal curve lies to the left of -0.52.

b) To find the z-value that corresponds to the 50th percentile, we can follow the same process. The 50th percentile corresponds to the middle 50% of the distribution, or the point where the distribution is split in half.

Using a table or calculator, we can find that the z-value that corresponds to the 50th percentile is 0. This means that half of the area under the standard normal curve lies to the left of 0, and the other half lies to the right.

c) Without a specific percentile value given, it's difficult to find the corresponding z-value. However, we can use the same process and plug in the desired percentile to find the corresponding z-value.

For example, if we wanted to find the z-value that corresponds to the 75th percentile, we would first convert 75th percentile to a percentage (75%) and then use a table or calculator to find the z-value that corresponds to that percentage.

Step-by-step explanation:

The probability that a randomly selected woman is less than 62 inches tall is approximately  20.23%.

To solve this problem, we need to standardize the height value of 62 inches using the mean and standard deviation given.

Allow X be the height of adult women in France. Then we've got:

X ~ N(64, 2.4)

To discover the probability that a randomly chosen woman is less than 62 inches tall, we need to discover P(X < 62).

Using the standard regular distribution components, we can standardize X as follows:

Z = (X - μ) / σ

Where μ is the imply and σ is the standard deviation of the regular distribution, and Z is a general regular random variable.

Substituting the given values, we get:

Z = (62 - 64) / 2.4 = -0.8333 (approx)

Now, we want to discover the chance P(Z < -0.8333) using the standard normal distribution table or a calculator.

Using a standard normal distribution table, we discover that

P(Z < -0.8333) is approximately 0.2023.

Therefore, the probability that a randomly selected woman is less than 62 inches tall is approximately 0.2023 or 20.23%.

The bottom width and depth of the trapezoidal channel are 2.25 m and 1.67 m, respectively.

In Windsor area of New South Wales, flood flow needs to be drained from a small locality at a rate of 120 m³/s in uniform flow using an open channel (n=0.018) Given the bottom slope as 0.0013 calculate the dimensions of the best cross section if the shape of the channel is (a) circular of diameter D and (b) trapezoidal of bottom width b.

(a) Circular channel:

For a circular channel, the best hydraulic section can be achieved by using the formula,

Q = (1 / n) x (A / P)2 / 3 x S0.5

where Q is the discharge; A is the area of the flow section; P is the wetted perimeter, S is the slope of the channel; and n is the roughness coefficient of the channel.

Assuming that the channel is flowing at full capacity, the depth of flow can be calculated using the following formula,

Q = (1 / n) x (π / 4) x D2 / 2 x D1 / 2 x S0.5

where D is the diameter of the channel; S is the slope of the channel; and n is the roughness coefficient of the channel.

Solving for D,

D = (8Q / πnD12S0.5)

For the given values of Q, n, and S,

D = (8 × 120 / π × 0.018 × 0.00132 × 120.5)

D = 1.98 m

Therefore, the diameter of the circular channel is 1.98 m.

(b) Trapezoidal channel:

For a trapezoidal channel, the best hydraulic section can be achieved by using the formula,

Q = (1 / n) x (A / P)2 / 3 x S0.5

where Q is the discharge; A is the area of the flow section; P is the wetted perimeter, S is the slope of the channel; and n is the roughness coefficient of the channel.

Assuming that the channel is flowing at full capacity, the depth of flow can be calculated using the following formula,

Q = (1 / n) x ((b + y) / 2) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5 x S0.5

where b is the bottom width of the channel; y is the depth of flow in the channel; S is the slope of the channel; and n is the roughness coefficient of the channel.

Rewriting the equation,

120 = (1 / 0.018) x ((b + y) / 2) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5 x (0.0013)0.5

Simplifying the equation,

658.5366 = (b + y) y / ((b / 2)2 + y2)0.5 x ((b / 2)2 + y2)0.5

Squaring both sides,

433407.09 = (b + y)2 y2 / ((b / 2)2 + y2) x ((b / 2)2 + y2)

Multiplying both sides by ((b / 2)2 + y2),

433407.09 ((b / 2)2 + y2) = (b + y)2 y2 x ((b / 2)2 + y2)

Simplifying the equation,

216703.545 = b2 y3 / 4 + b y4 / 2 + y5 / 4

Solving the above equation by using trial and error, the bottom width and depth of the trapezoidal channel are 2.25 m and 1.67 m, respectively.

Step-by-step explanation:

a) The bird would fly approximately 4.17 km in a straight line from the starting point to the final point. b) The bird would fly at an angle of approximately 47.46 degrees counterclockwise from the east.

To find the distance and angle that a bird would fly in a straight line from the starting point to the final point, we can use the concept of vector addition.

(a) Distance:

The person's total displacement can be represented as a vector sum of their individual movements: 2.8 km north + 2.9 km west - 5.8 km south.

To simplify this, we can break it down into horizontal (x-axis) and vertical (y-axis) components:

Horizontal displacement = -2.9 km (west)

Vertical displacement = 2.8 km (north) - 5.8 km (south) = -3 km (south)

Now, we can calculate the straight-line distance using the Pythagorean theorem:

Distance = √(Horizontal displacement² + Vertical displacement²)

= √((-2.9 km)² + (-3 km)²)

= √(8.41 km² + 9 km²)

= √(17.41 km²)

≈ 4.17 km

Therefore, the bird would fly approximately 4.17 km in a straight line from the starting point to the final point.

(b) Angle:

To determine the angle counterclockwise from the east, we can use trigonometry. The angle can be found using the inverse tangent function:

Angle = arctan(Vertical displacement / Horizontal displacement)

= arctan((-3 km) / (-2.9 km))

= arctan(1.034)

≈ 47.46 degrees

Therefore, the bird would fly at an angle of approximately 47.46 degrees counterclockwise from the east.

A charter flight club charges its members $320 per year. Therefore, having 20 members over 100 will lead to maximum revenue for the charter flight club.

We know that the club charges $320 per year for each member. However, for each new member in excess of 100, the charge for every member is reduced by $2. So, if we have x members over 100, the charge for each member will be $320 - $2x.

To calculate the total revenue, we need to multiply the number of members by the charge per member. Let's denote the total revenue as R and the number of members as N:

R = (100 + x) * (320 - 2x)

To find the value of x that maximizes the revenue, we can differentiate the revenue function with respect to x and set it equal to zero:

dR/dx = 320 - 4x - 2(100 + x) = 0

Simplifying the equation:

320 - 4x - 200 - 2x = 0

-6x + 120 = 0

6x = 120

x = 20

Therefore, having 20 members over 100 will lead to maximum revenue for the charter flight club.
