Answer:

The speed of a point on the rim of the wheel is approximately 207 feet per minute.

Step-by-step explanation:

we need to convert the given information into consistent units and apply the appropriate conversion factors.

Given:

Angular speed: 5 radians/sec

Diameter of the wheel: 83 inches

To convert the diameter from inches to feet, we divide it by 12 since there are 12 inches in a foot:

Diameter in feet = 83 inches / 12 = 6.92 feet (rounded to two decimal places)

To calculate the circumference of the wheel, we multiply the diameter by π (pi), which is approximately 3.14159:

Circumference = π * Diameter = 3.14159 * 6.92 feet ≈ 21.73 feet (rounded to two decimal places)

Now we have the distance traveled by a point on the rim in one revolution (circumference).

To find the speed in feet per minute, we need to convert the angular speed from radians per second to revolutions per minute.

Since there are 2π radians in one revolution, and 60 seconds in one minute, we can use the following conversion factor:

1 revolution/second = (1 revolution/2π radians) * (2π radians/1 revolution) * (60 seconds/1 minute) = 60/2π ≈ 9.55 revolutions/minute

Therefore, the speed of a point on the rim of the wheel is approximate:

21.73 feet/revolution * 9.55 revolutions/minute ≈ 207.41 feet/minute (rounded to two decimal places)

So, to the nearest foot, the speed of a point on the rim of the wheel is approximately 207 feet per minute.

The correct option is C. It is safe to apply the central limit theorem, even if the sample size for each sample is 15, if the sample population is normally distributed.

The central limit theorem states that, if you take repeated samples of a population and calculate the mean of each sample, the distribution of the means of those samples will tend to be normally distributed, provided that the sample size is large enough. This means that, even if the original population is not normally distributed, the distribution of the means of the samples will tend towards a normal distribution as the sample size increases.

However, if the original population is already normally distributed, then you can apply the central limit theorem with a smaller sample size and still expect the distribution of the means of the samples to be normally distributed. Therefore, in order for it to be safe to apply the central limit theorem with a sample size of 15, the sample population must be normally distributed.

The measure of angles inside the rhombus are:

∠1 = 56

∠2 = 56

∠3 = 34

∠4 = 34

We have,

In a rhombus,

The opposite angle is congruent.

So,

(56 + 56) = ∠1 + ∠2

And,

∠1 and ∠2 are equal angles.

So,

112 = 2∠1

∠1 = 56

∠2 = 56

Now,

All four angles in side the rhombus = 360

112 + 112 + ∠x + ∠x = 360

2∠x = 360 - 224

2∠x = 136

∠x = 68

This ∠x is the angle inside the rhombus.

And, ∠x/2 = ∠3 = ∠4

The platelet count is 652 x 10^3.

Based on the information provided, it seems that the platelet count from a test result is 652, and the normal range for platelet count is 150,000 to 450,000 platelets per microliter of blood. The value "10(3)" likely refers to the measurement being in thousands.

To convert the measurement to the standard unit of platelet count, we need to multiply the given value by 1,000. Thus, 652 * 1,000 = 652,000 platelets per microliter.

It's important to note that platelet counts can vary depending on various factors, and medical professionals typically interpret the results in conjunction with other clinical information. If the obtained value of 652,000 platelets per microliter is accurate, it would be significantly higher than the upper limit of the normal range.

It's crucial to consult a healthcare professional or a qualified medical practitioner for an accurate interpretation of test results and any necessary medical advice or treatment.

The rhombus earns the most points because it has the shortest perimeter, which is worth the most points at 3, and it still earns 1 point for having a right angle.

To determine which game piece is worth the greatest total 6 points, we need to evaluate each piece's attributes and determine which combination of attributes will result in the highest point value.

Let's start by looking at each game piece and its attributes:

Now, let's add up the points for each game piece:

Right angle: 1 + 0 + 0 = 1

Square: 1 + 2 + 0 = 3

Parallelogram: 1 + 2 + 0 = 3

Rhombus: 1 + 0 + 3 = 4

The equation that can be used to find the speed of the current, c, in miles per hour is 3(15 - c) = 2(15 + c). The boat's speed when going upstream can be given by⇒ the speed in calm water - the speed of the current. Similarly, the boat's speed when going downstream can be given by⇒ the speed in calm water + the speed of the current.

To explain this equation:
- The boat's speed in calm water is given as 15 mph.
- When traveling upstream (against the current), the boat takes 3 hours to travel a certain distance.
- When traveling downstream (with the current), the boat takes 2 hours to travel the same distance.
- The speed of the current affects the boat's overall speed, so we need to find the value of c.

Distance traveled by the boat upstream = speed x time = (15-c) x 3

Distance traveled by the boat downstream = speed x time = (15+c) x 2

We know that both the distances are same.
So ⇒ 3(15 - c) = 2(15 + c)

Probability that the ticketed passengers the proportion of no-shows in a sample would be greater then 7% is 4.9465.

Given that,

A director of reservations estimates that 7% of the passengers with tickets do not arrive.

We have to find what is the probability that a sample of 445 ticketed passengers would have a no-show rate that was higher than 3% different from the general rate, if the director is correct.

We can write as

Number of no shows ticketed passenger is 7% of 445

= 7% × 445 =31.15

Now,

We have to find probability that 31.15 people or less will be no shows.

Probability of No show ticketed passengers, p = 3% = 0.03

Probability of ticketed passengers who show tickets, q = 97% = 0.97

Mean Number of no shows = 3% of 445

= 0.03 × 445 = 13.35

The Standard Deviation for no show can be written as ,

σ =\(\sqrt{n\times p \times q}\)

σ =\(\sqrt{445 \times 0.03 \times 0.97}\)

σ =\(\sqrt{12.9495}\)

σ =3.5985

Now, z-score is x-μ/σ

=31.15-13.35/3.5985

=17.8/3.5985

=4.9465

Therefore, Probability that the proportion of no-shows in a sample would be less than 7% is 4.9465.

a. The probability of drawing a red ball from Box 1 is 30%.

b. If a red ball is drawn from Box 1, the probability of drawing another red ball from Box 2 on the second round is 60%.

c. If the first draw from Box 1 was black, the conditional probability of drawing a red ball from Box 3 on the second draw is 80%.

d. The probability of drawing two red balls at both draws, without any prior information, is 46%.

e. The probability of drawing a red ball at the first draw and a black ball at the second draw, without any prior information, is 21%.

a. The probability of drawing a red ball from Box 1 can be calculated by dividing the number of red balls in Box 1 by the total number of balls in Box 1. Therefore, the probability is 3/(3+7) = 3/10 = 0.3 or 30%.

b. Since a red ball was drawn from Box 1, we only consider the balls in Box 2. The probability of drawing a red ball from Box 2 is 6/(6+4) = 6/10 = 0.6 or 60%. Therefore, the probability of drawing another red ball when the first ball drawn from Box 1 is red is 60%.

c. If the first draw from Box 1 was black, we only consider the balls in Box 3. The probability of drawing a red ball from Box 3 is 8/(8+2) = 8/10 = 0.8 or 80%. Therefore, the conditional probability of drawing a red ball from Box 3 when the first ball drawn from Box 1 was black is 80%.

d. Before any draws, the probability of drawing two red balls at both draws can be calculated by multiplying the probabilities of drawing a red ball from Box 1 and a red ball from Box 2. Therefore, the probability is 0.3 * 0.6 = 0.18 or 18%. However, since there are two possible scenarios (drawing red balls from Box 1 and Box 2, or drawing red balls from Box 2 and Box 1), we double the probability to obtain 36%. Adding the individual probabilities of each scenario gives a total probability of 36% + 10% = 46%.

e. Before any draws, the probability of drawing a red ball at the first draw and a black ball at the second draw can be calculated by multiplying the probability of drawing a red ball from Box 1 and the probability of drawing a black ball from Box 2 or Box 3. The probability of drawing a red ball from Box 1 is 0.3, and the probability of drawing a black ball from Box 2 or Box 3 is (7/10) + (2/10) = 0.9. Therefore, the probability is 0.3 * 0.9 = 0.27 or 27%. However, since there are two possible scenarios (drawing a red ball from Box 1 and a black ball from Box 2 or drawing a red ball from Box 1 and a black ball from Box 3), we double the probability to obtain 54%.

So, we can see that the 4 in the original expression represents the height of the trapezoidal tabletop in feet.

The area of a trapezoid can be found by using the formula:

\(A = 1/2 * (b_1 + b_2) * h\)

where A is the area, b1 and b2 are the lengths of the two parallel sides (the bases), and h is the height of the trapezoid.

In this case, we are given that the bases have lengths x and 2x, and the height is x + 4. So, we can substitute those values into the formula and simplify:

\(A = 1/2 * (x + 2x) * (x + 4)\)

\(= 1/2 * 3x * (x + 4)\)

\(= 3/2 * x^2 + 6x\)

So, the expression \(\frac{x+2}{2} *(x+4)\) represents the area of the trapezoidal tabletop, which is equal to\(3/2 * x^2 + 6x\).

Now, we need to determine what 4 represents in the expression (x + \(\frac{x+2}{2} *(x+4)\).

The expression (x + 2x)/2 represents the average of the two base lengths, which is equal to (3x)/2. The expression (x+4) represents the height of the trapezoid.

So, the expression \(\frac{x+2}{2} *(x+4)\) can be rewritten as:

\(\frac{(3x)}{2} * (x+4)\)

Expanding this expression, we get:

\(3/2 * x^2 + 6x\)
