The total number of eggs is 1542.

To find the total number of eggs, we can use the fact that the 540 eggs sold represent 35% of the total eggs. We can start by setting up a proportion:

35/100 = 540/x

where x is the total number of eggs. To solve for x, we can cross-multiply and simplify:

35x = 54000

x = 54000/35

x = 1542.86

Therefore, the total number of eggs is approximately 1542.86. Since we can't have a fraction of an egg, we can assume that the total number of eggs is 1542.

To find the number of eggs that are not sold, we can subtract the number of eggs sold from the total number of eggs:

1542 - 540 = 1002

90 mm Hg is Zigg's mean arterial pressure.

Here's the formula for calculating MAP: MAP = (CO x SVR) + CVPR

where:

CO stands for cardiac output (measured in liters per minute).

SVR stands for systemic vascular resistance (measured in mm Hg/L/min).

CVPR stands for central venous pressure (measured in mm Hg).

Now, let's get started with the calculation of MAP.

First, let's calculate CO (cardiac output): CO = HR x SV

where:

HR is heart rate (measured in beats per minute).

SV is stroke volume (measured in milliliters per beat).

CO = 140 bpm x 95 mlCO = 13300 ml/minCO = 13.3 L/min

Next, we need to calculate SVR (systemic vascular resistance).

The formula for calculating SVR is: SVR = (MAP - CVP) / CO

where:

MAP is mean arterial pressure (measured in mm Hg).

CVP is central venous pressure (measured in mm Hg).

CO is cardiac output (measured in liters per minute).

Since we don't have CVP in this question, let's assume it to be zero.

SVR = (MAP - 0) / 13.3 L/minSVR = MAP / 13.3 L/min

Now, we can rearrange the above equation to calculate

MAP:

MAP = SVR x 13.3 L/minMAP = 60 mm Hg (diastolic pressure) + 1/3 (systolic pressure - diastolic pressure)MAP = 60 mm Hg + 1/3 (150 mm Hg - 60 mm Hg)MAP = 60 mm Hg + 30 mm HgMAP = 90 mm Hg

Therefore, Ziggy's mean arterial pressure (MAP) is 90 mm Hg.

(a) To set up a proof by contradiction for the statement "For each positive real number r, if r^2 = 18, then r is irrational," we will assume the opposite of the given statement. Specifically, we would assume that there exists a positive real number r such that r^2 = 18, and r is rational (not irrational).

(b) To complete the proof by contradiction, follow these steps:

1. Assume that there exists a positive real number r such that r^2 = 18, and r is rational.
2. Since r is rational, we can write it as a fraction a/b, where a and b are integers with no common factors other than 1 (i.e., a and b are coprime) and b ≠ 0.
3. We have r^2 = 18, so (a/b)^2 = 18.
4. Squaring both sides, we get a^2 / b^2 = 18.
5. Rearrange the equation: a^2 = 18b^2.
6. Since 18 is an even number, a^2 is also an even number, which implies that a is an even number (let's say a = 2k, where k is an integer).
7. Substitute a with 2k: (2k)^2 = 18b^2, which simplifies to 4k^2 = 18b^2.
8. Divide both sides by 2: 2k^2 = 9b^2.
9. Now, we see that the left side of the equation is an even number (2k^2), which implies that 9b^2 is also an even number. However, 9 is an odd number, so for 9b^2 to be even, b must be even.
10. Both a and b are even, which contradicts our original assumption that a and b are coprime (having no common factors other than 1).

Therefore, our assumption that there exists a positive real number r such that r^2 = 18 and r is rational leads to a contradiction. Thus, the original statement is true: for each positive real number r, if r^2 = 18, then r is irrational.

The probability that 5 or less students will withdraw from a math course if 30 students are enrolled is 0.6826.

This can be calculated using the binomial probability formula, which states that the probability of a certain number of successes in a certain number of trials is equal to the number of combinations of successes times the probability of each success. In this case, the probability of success (withdrawing) is 0.10 and the number of trials (students enrolled) is 30.

For this example, the probability of 5 or less successes (withdrawals) is calculated by adding together the probabilities of 0 successes, 1 success, 2 successes, 3 successes, 4 successes, and 5 successes. That gives us a probability of 0.6826.

This is equivalent to saying that 68.26% of students enrolled in a math course will not withdraw. It is also equivalent to saying that 31.74% of students enrolled in a math course will withdraw.

To illustrate this, if we assume that 30 students are enrolled in a math course, we would expect that approximately 19 students will not withdraw (68.26%) and approximately 11 students will withdraw (31.74%).

In conclusion, the probability that 5 or less students will withdraw from a math course if 30 students are enrolled is 0.6826.

The equation in standard form for the circle is (x + 4)² + (y - 6)² = 9.

The midpoint of the diameter is the center of the circle. Therefore, we can first find the midpoint:

Midpoint = [(x1 + x2)/2, (y1 + y2)/2] = [(-4 + (-4))/2, (9 + 3)/2] = [-4, 6]

The distance from the center to either endpoint of the diameter is the radius of the circle. In this case, the distance is:

r = |9 - 6| = 3

So we have the center (-4, 6) and the radius 3. Using the standard form equation of a circle, we can write:

(x - (-4))² + (y - 6)² = 3²

Simplifying and expanding, we get:

(x + 4)² + (y - 6)² = 9

Therefore, the equation in standard form for the circle is (x + 4)² + (y - 6)² = 9.

Answer:

In this problem, we have a right triangle where the hypotenuse is the 30-foot support cable and one leg is 22 feet (the distance from the base of the pole to where the cable is attached). To find the angle that the cable makes with the ground, we need to use trigonometry. The tangent of an angle in a right triangle is equal to the length of the opposite side divided by the length of the adjacent side. In this case, we want to find tan(θ), where θ is the angle between the cable and the ground. Therefore, tan(θ) = opposite/adjacent = 22/30 = 0.7333. Taking inverse tangent on both sides gives us θ = tan^-1(0.7333) ≈ 36.7 degrees to one decimal place. Therefore, to the nearest tenth, the measure of the angle that the cable makes with the ground is approximately 36.7 degrees.

Additional comments

The parity of the integer side lengths of a right triangle is always even. That is, there can be two odd side lengths, but never just one odd side length.

Side lengths 54 and 66 are even, while length 87 is odd. There is only one odd side length, so this triangle cannot be a right triangle.

A tangent always meets a radius at right angles, so XY is a tangent if and only if angle X is a right angle.

The unit rate at which the bakery makes donuts is 2 donuts per minute.

The slope of the line would also be 2 since the number of donuts made is directly proportional to the time elapsed. This means that for every minute that passes, 2 donuts are made.

To find the unit rate, we divide the total number of donuts made (30) by the time it takes to make them (15 minutes).

Unit rate = 30 donuts ÷ 15 minutes = 2 donuts per minute

To find the slope of the line, we use the formula:

slope = rise ÷ run

Answer:

(a) To find the mean value, we sum up all the values and divide by the number of values:

Mean = (17 + 22 + 25 + 27 + 32 + 40 + 45 + 51 + 59 + 62) / 10 = 36.0

So, the mean value is 36.0.

To find the median value, we first need to put the data set in order from smallest to largest:

17, 22, 25, 27, 32, 40, 45, 51, 59, 62

The median is the middle value of the data set, which is 36 in this case.

So, the median value is 36.0.

(b) To find the mean absolute deviation (MAD), we first need to find the deviation of each value from the mean:

|17 - 36.0| = 19.0

|22 - 36.0| = 14.0

|25 - 36.0| = 11.0

|27 - 36.0| = 9.0

|32 - 36.0| = 4.0

|40 - 36.0| = 4.0

|45 - 36.0| = 9.0

|51 - 36.0| = 15.0

|59 - 36.0| = 23.0

|62 - 36.0| = 26.0

Next, we find the mean of these deviations:

MAD = (19.0 + 14.0 + 11.0 + 9.0 + 4.0 + 4.0 + 9.0 + 15.0 + 23.0 + 26.0) / 10

MAD = 13.0

So, the mean absolute deviation for this data set is 13.0.

(c) To find the percentage of the data set that lies closer than the MAD to the mean, we count how many values are within one MAD of the mean. We have:

17, 22, 25, 27, 32, 40, 45, 51, 59, 62

The values within one MAD of the mean (36.0 +/- 13.0) are:

17, 22, 25, 27, 32, 40, 45, 51

So, 8 out of 10 values are within one MAD of the mean.

The percentage of the data set that lies closer than the MAD to the mean is:

8 / 10 * 100% = 80%

(a) To find the mean value, we sum up all the values and divide by the number of values:

Mean = (7 + 7 + 7 + 8 + 8 + 9 + 10 + 32) / 8 = 9.5

So, the mean value is 9.5.

To find the mean absolute deviation (MAD), we first need to find the deviation of each value from the mean:

|7 - 9.5| = 2.5

|7 - 9.5| = 2.5

|7 - 9.5| = 2.5

|8 - 9.5| = 1.5

|8 - 9.5| = 1.5

|9 - 9.5| = 0.5

|10 - 9.5| = 0.5

|32 - 9.5| = 22.
