a) The mean height of adult women in this distribution is 63.5 inches.

b) The standard deviation of heights in this distribution is 4.06 inches.

To calculate the mean and standard deviation of heights in inches, we need to convert the heights given in feet and inches to inches. We can use the formula:

height in inches = 12 x height in feet + height in inches

For the 10th percentile height:

height in inches = 12 x 5 + 0 = 60 inches

For the 90th percentile height:

height in inches = 12 x 5 + 7 = 67 inches

(a) To find the mean height, we can use the formula:

mean = (10th percentile + 90th percentile) / 2

mean = (60 + 67) / 2

mean = 63.5 inches

(b) To find the standard deviation, we can use the formula:

standard deviation = (90th percentile - 10th percentile) / (2 x 1.645)

where 1.645 is the z-score corresponding to a 90% confidence interval.

standard deviation = (67 - 60) / (2 x 1.645)

standard deviation = 4.06 inches

The total surface area of the pyramid is 261 square feet.

The area of a square of sidelength S is:

A = S^2

And the area of a triangle of base B and height H is:

a = B*H/2

Here we have a square base of 9ft by 9ft, then its area is:

A = (9ft)^2 = 81 ft^2

And 4 triangular faces with a base of 9ft and a height of 10 ft, then the area of each one is:

a = 9ft*10ft/2 = 45 ft^2

Then the total area of the pyramid is:

A coterminal angle is an angle that has the same initial side and terminal side as a given angle. The difference between the angle and the coterminal angle is a multiple of 360 degrees.

The following steps can be used to find a coterminal angle between 0 and 360 degrees:

Step 1: Identify the given angle. Let's assume that the given angle is 100 degrees.

Step 2: Add or subtract multiples of 360 degrees to the given angle to obtain a new angle that has the same initial and terminal sides. To obtain the angle that is between 0 and 360 degrees, add or subtract 360 degrees from the angle until the result is between 0 and 360 degrees.There are two ways to do this.

The first method is to add or subtract multiples of 360 until the result is between 0 and 360 degrees. The second method is to divide the given angle by 360 degrees and then multiply the quotient by 360 degrees.

The first method:Subtract 360 degrees from 100 degrees to get -260 degrees. Add 360 degrees to -260 degrees to get 100 degrees, which is between 0 and 360 degrees. Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

The second method:Divide 100 degrees by 360 degrees to get a quotient of 0.27777777778. Multiply 0.27777777778 by 360 degrees to obtain 100 degrees, which is between 0 and 360 degrees.

Therefore, 100 degrees and 460 degrees are coterminal angles between 0 and 360 degrees.

Because 88.9% of the data falls between approximately 47.62 and Blank.

The extreme point (x*, y*) of the function z = 3x² - xy + y² + 5x + 3y + 18 is (-1, -1), and it is a maximum point.

To find the extreme point, we need to find the critical points of the function. We take the partial derivatives with respect to x and y and set them equal to zero:

∂z/∂x = 6x - y + 5 = 0 ... (1)

∂z/∂y = -x + 2y + 3 = 0 ... (2)

Solving equations (1) and (2) simultaneously, we find x = -1 and y = -1. Substituting these values back into the original function, we get z = 3(-1)² - (-1)(-1) + (-1)² + 5(-1) + 3(-1) + 18 = 19.

To determine the nature of the extreme point, we need to analyze the second partial derivatives. Calculating the second partial derivatives:

∂²z/∂x² = 6

∂²z/∂y² = 2

∂²z/∂x∂y = -1

The discriminant D = (∂²z/∂x²)(∂²z/∂y²) - (∂²z/∂x∂y)² = (6)(2) - (-1)² = 12 - 1 = 11, which is positive. This indicates that the point (-1, -1) is a maximum point.

Khalid can make a maximum of 7 batches of muffins using the available cornmeal because he only has 2 bags of cornmeal, and each bag provides 25 cups. Hence, the correct answer is (a) 7.

To calculate the maximum number of batches, we need to consider the total amount of cornmeal available and the amount required per batch. Khalid has 2 bags of cornmeal, with each bag containing 25 servings. Since one serving is equivalent to one cup, each bag has 25 cups of cornmeal.For each batch of muffins, 2.5 cups of cornmeal are required. Therefore, to determine the maximum number of batches, we divide the total amount of cornmeal by the amount required per batch: 25 cups / 2.5 cups per batch = 10 batches.

To determine the number of possible subcommittees with three members out of seven, we can use the concept of combinations. In this case, we want to select three members from a group of seven.

The number of possible subcommittees can be calculated using the formula for combinations:

C(n, r) = n! / (r!(n - r)!)

where n is the total number of members and r is the number of members to be selected for the subcommittee.

Using this formula, we have:

C(7, 3) = 7! / (3!(7 - 3)!)

= 7! / (3! * 4!)

= (7 * 6 * 5) / (3 * 2 * 1)

= 35

The 7th term of the sequence is 48.

Sequence is an ordered arrangement of elements. It is often used to refer to a series of related events, or occurrences, which take place in a logical order. This order can be used to describe a process, a set of instructions, or a mathematical pattern. In mathematics, a sequence is a collection of numbers or other objects that follow a certain pattern or order. Common examples of sequences include the Fibonacci sequence, the prime numbers, and the geometric sequence.

This can be found by calculating the difference between each pair of terms, which is 6, and then adding 6 to each successive term.

Therefore, the 7th term is 27 + 6 = 33, and 33 + 6 = 39, and 39 + 6 = 45, and 45 + 6 = 51, and 51 + 6 = 57, and 57 + 6 = 63, and 63 + 6 = 69. Rounded to the nearest integer, the 7th term is 48.

To determine the number of bridge hands that contain exactly two aces or exactly five diamonds or both, we need to consider each condition separately and then combine the results.

To find the number of hands with exactly two aces, we first choose two out of the four aces, which can be done in (4 choose 2) = 6 ways. The remaining 11 cards can be chosen from the remaining 48 cards in (48 choose 11) ways. So, there are 6 * (48 choose 11) hands with exactly two aces.

To find the number of hands with exactly five diamonds, we choose five out of the 13 diamonds, which can be done in (13 choose 5) ways. The remaining 8 cards can be chosen from the remaining 39 cards in (39 choose 8) ways. So, there are (13 choose 5) * (39 choose 8) hands with exactly five diamonds.

To find the number of hands that satisfy both conditions (two aces and five diamonds), we multiply the results from the previous two steps. So, the number of hands with exactly two aces or exactly five diamonds or both is 6 * (48 choose 11) + (13 choose 5) * (39 choose 8).

For the second question, let's consider the following scenarios:

a) If each school can receive any number of projectors, the problem is equivalent to distributing 9 identical projectors among 5 distinct schools without any restrictions. In this case, the number of divisions is given by (9 + 5 - 1) choose (5 - 1) = (13 choose 4) = 715 divisions.

b) If each school must receive at least one projector, we can distribute 1 projector to each school initially, which leaves us with 4 projectors remaining. The problem is then reduced to distributing 4 identical projectors among 5 distinct schools without any restrictions, which gives us (4 + 5 - 1) choose (5 - 1) = (8 choose 4) = 70 divisions.

For the third question:

The total number of different outcomes when catching 10 fish, considering 5 distinct types, is given by the number of ways to distribute 10 indistinguishable fish into 5 distinct categories. This can be calculated using stars and bars or the concept of compositions, resulting in (10 + 5 - 1) choose (5 - 1) = (14 choose 4) = 1001 different outcomes.

When 3 out of the 10 fish caught are trout, we first choose 3 trout out of the 5 available types, which can be done in (5 choose 3) = 10 ways. The remaining 7 fish can be distributed among the remaining 4 types in (7 + 4 - 1) choose (4 - 1) = (10 choose 3) = 120 ways. So, there are 10 * 120 = 1200 different outcomes when 3 out of the 10 fish caught are trout.

When at least 2 out of the 10 fish caught are trout, we subtract the outcome where only 1 trout is caught from the total number of outcomes. The number of outcomes with only 1 trout is given by (5 choose 1) * (9 choose 9) = 5 ways. Therefore, the number of different outcomes when at least 2 out of the 10 fish caught are trout is 1001 - 5 = 996 different outcomes.

The height of the image formed by a concave mirror when an object of height 2 cm is placed 4 cm in front of the mirror and the focal length is 3 cm can be calculated using the mirror equation and magnification formula. The height of the image will be -1.5 cm.

To find the height of the image formed by a concave mirror, we can use the mirror equation:

1/f = 1/d_o + 1/d_i

Where:

f is the focal length of the concave mirror,

d_o is the object distance (distance between the object and the mirror),

and d_i is the image distance (distance between the image and the mirror).

In this case, the object distance (d_o) is 4 cm and the focal length (f) is 3 cm. Plugging these values into the mirror equation, we can solve for the image distance (d_i):

1/3 = 1/4 + 1/d_i

To simplify the equation, we can find the common denominator:

1/3 = (1 * d_i + 4) / (4 * d_i)

Now, cross-multiply and solve for d_i:

4 * d_i = 3 * (d_i + 4)

4 * d_i = 3 * d_i + 12

d_i = 12 cm

The image distance (d_i) is positive, indicating that the image is formed on the same side of the mirror as the object. Since the object is placed in front of the mirror, the image is also in front of the mirror.

Next, we can calculate the magnification (m) using the formula:

m = -d_i / d_o

Plugging in the values, we have:

m = -12 / 4

m = -3

The negative sign in the magnification indicates that the image formed is inverted compared to the object.

Finally, we can find the height of the image (h_i) using the magnification formula:

m = h_i / h_o

Where h_o is the height of the object.

Plugging in the values, we have:

-3 = h_i / 2

Solving for h_i:

h_i = -3 * 2

h_i = -6 cm

The negative sign indicates that the image is inverted compared to the object, and the absolute value of the height tells us the magnitude. Therefore, the height of the image formed by the concave mirror when the object of height 2 cm is placed 4 cm in front of the mirror is 6 cm, but the image is inverted.
