Answer:

The constant of proportionality k = 11.5.

The equation will be: \(\mathbf{y=11.5(x)}\)

Step-by-step explanation:

If x represents number of hours than y represents miles

We are given:

x        y

4         46

5         57.5

6         69

The constant of proportionality can be found using formula: \(k=\frac{y}{x}\)

Putting values and finding k

x        y               k (\(k=\frac{y}{x}\))

4         46            11.5

5         57.5         11.5

6         69            11.5

So, the constant of proportionality k = 11.5

Now, The equation will be:

\(k=\frac{y}{x}\\or \\y=kx\\Put \ k=11.5\\y=11.5(x)\)

So, the equation will be: \(\mathbf{y=11.5(x)}\)

The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.

From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:

= 0.5π / 180

= 0.008727 radians

Distance from the sun = 150 × 10^6

The physical diameter of the sun will be:

= 150 × 10^6 × 0.008727

= 1309000km

The difference between the diameters will be:

= 1390000 - 1309000

= 8.1 × 10^4.

The percentage of difference will be:

= (8.1 * 10^4) / 1390000 × 100

= 5.8%

The probability of drawing a king from a standard deck of 52 cards is 1/13.

In a standard deck of 52 playing cards, there are four kings: the king of hearts, the king of diamonds, the king of clubs, and the king of spades.

To find the probability of drawing a king, we need to determine the ratio of favorable outcomes (drawing a king) to the total number of possible outcomes (drawing any card from the deck).

The total number of possible outcomes is 52 because there are 52 cards in the deck.

The favorable outcomes, in this case, are the four kings.

Therefore, the probability of drawing a king is given by:

Probability = (Number of favorable outcomes) / (Number of possible outcomes)

= 4 / 52

= 1 / 13

Thus, the probability of drawing a king from a standard deck of 52 cards is 1/13.

This means that out of every 13 cards drawn, on average, one of them will be a king.

It is important to note that the probability of drawing a king remains the same regardless of any previous cards that have been drawn or any other factors.

Each draw is independent, and the probability of drawing a king is constant.

Answer:

p = - 5

Step-by-step explanation:

–2.5p – 20 = 9p + 37.5

combine like terms:

- 2.5p - 9p = 37.5 + 20

simplify:

- 11.5p = 57.5

p = 57.5 / -11.5

p = - 5

Answer:

The answer is p = -5

Step-by-step explanation:

-2.5p - 20 = 9p + 37.5

(move constants to one side by adding 20 to both sides)

-2.5p = 9p + 57.5

(move all terms with the "p" variable to one side by subtracting 9 from both sides)

-11.5p = 57.5

(divide both sides by -11.5 to isolate the variable)

The data points from the set of collected that are outside the [-2, 2] range means that the data is an outlier or unusual data

The z–score also known as standard score is the number of standard deviation a score is differs from the mean or average score

The z–score is given by the formula;

\(Z = \frac{x - \mu}{ \sigma} \)

The Z–Score is therefore, the number of standard deviations, a data point, x is far from the mean, \( \mu \)

The standard deviation, \( \sigma \), is given by the formula;

\( \sigma = \sqrt{ \frac{ \sum {( x_{i} - \mu)}^{2} }{N} } \)

As the value of \( \sigma \) increases, the variability increases, and the Z–Score decreases, such that a Z–Score of less than -2 or greater than 2 are unusual.

From the z–score calculator, the probability that a data point has a z–score of less than -2 or more than 2 is 0.02275

Such a data point can be taken as an outlier

Therefore, data that is outside the [-2, 2] range is an unusual (outlier) data

Hence the output variable (total weekly earnings) is a function of the input variable (number of hours worked as a payroll clerk) and may be expressed by the equation y = 16x + 120.

A variable is anything that may be altered in the context of a mathematical notion or experiment. Variables are frequently denoted by a single symbol. .

a. Input variables: hours worked as a cashier, payroll clerk, and assistant.

The total amount earned each week is the output variable.

b. To determine the weekly total, multiply the number of hours worked at each job by the hourly rate and put them together. As a result, the equation would be:

Total weekly wage = (hours worked as a cashier x cashier hourly rate) + (hours worked as a payroll clerk x payroll clerk hourly rate) + (hours worked as an aide x rate per hour as an aide)

c. The amount of hours worked as an assistant is always 10 hours fewer than that of a payroll clerk. Therefore, if x denotes the number of hours worked as a payroll clerk, then the number of hours worked as an assistant may be denoted as (x - 10).

d. The equation describing the total money earned each week is as follows:

(20 x 9.5) + (x x 9) + ((x - 10) x 7) = y

This expression is simplified as follows:

y = 190 + 9x - 70 + 7x

y = 16x + 120

Hence the output variable (total weekly earnings) is a function of the input variable (number of hours worked as a payroll clerk) and may be expressed by the equation y = 16x + 120.

f. The realistic replacement values for x would be determined by the maximum number of hours you may work at each job as well as the amount of time available to work. Working 8 hours as a payroll clerk may be a reasonable substitute value if you have restricted availability, but 50 hours is unlikely.

g. If you do not work as an aide, you may calculate your total weekly income by setting the number of hours worked as an aide to zero in the calculation for the total amount earned each week. This results in:

y = 16x + 120 + 0

y = 16x + 120

As a result, the total weekly wage would be determined only by the number of hours performed as a cashier and payroll clerk.

Answer:

Therefore, the Panthers had a better overall record for the season, with a total of 212 points earned compared to the Cowboys' total of 173 points.

Step-by-step explanation:

To compare the measures of center, we can calculate the mean and median points earned by each team:

Panthers: Mean = 212/15 = 14.13 points, Median = 14 points

Cowboys: Mean = 173/15 = 11.53 points, Median = 10 points

Based on these calculations, we can see that the Panthers have a larger mean value of about 14.13 points compared to the Cowboys' mean value of about 11.53 points. However, the median value for both teams is less useful for comparison since they are only one point apart. Therefore, we can conclude that the Panthers had the better overall record for the season based on both the total points earned and their larger mean value.

So, the answer is Panthers; they have a larger mean value of about 14.8 points (Option C is incorrect as the mean value of Panthers is approximately 14.13 and not 14.8).

the package should be released about 9,932 meters before the target to hit the target, rounded to the nearest meter.

what is  rounded to the nearest  ?

"Rounded to the nearest" means finding the nearest value of a specified degree of accuracy. For example, rounding a number to the nearest whole number means finding the closest whole number to that number. If the number is equally close to two whole numbers, it is rounded up to the higher number.

In the given question,

The trajectory of the package can be modeled using the equation:

y = -0.5 * g * x² / v² + tan(∅) * x + h

where:

y = height of the package above the ground at horizontal distance x

g = acceleration due to gravity (9.8 m/s²)

v = horizontal velocity of the drone (100 m/s)

theta = angle at which the package is released

h = initial height of the package above the ground (4500 meters)

To hit the target, we want the package to land on the ground, which means its final height should be zero. So, we can set y = 0 and solve for x to find the horizontal distance at which the package should be released. This gives:

0 = -0.5 * 9.8 * x² / 100² + tan(∅) * x + 4500

Simplifying and rearranging, we get:

0.049 * x² + tan(∅) * x - 4500 = 0

Using the quadratic formula, we can solve for x:

x = (-tan(∅) ± √(tan²(∅) + 0.049 * 4500 * 4)) / (0.098)

Since we want the package to land in front of the target, we take the positive root of the equation:

x = (-tan(∅) + √(tan²(∅) + 0.049 * 4500 * 4)) / (0.098)

Now, we need to find the value of theta that will make the package hit the target. Since the drone is traveling horizontally, the package will also have a horizontal velocity of 100 m/s when it is released. So, we can use trigonometry to find the angle at which the package should be released. This gives:

tan(∅) = 4500 / x

Substituting this into the equation for x, we get:

x = (-4500 / x + √((4500 / x)²+ 0.049 * 4500 * 4)) / (0.098)

Simplifying and rearranging, we get:

x² = 4500 * (√((4500 / x)² + 0.049 * 4500 * 4) - 4500 / x) / 0.098

Squaring both sides, we get:

x⁴ = 4500² * (√((4500 / x)² + 0.049 * 4500 * 4) - 4500 / x)² / 0.009604

Expanding and simplifying, we get:

x⁴ = 900000000 * (1 + 0.00012345679 * x² - 0.00012345679 * 4500 * x / √(x² + 202500)) / 0.009604

We can solve for x using numerical methods, such as using a graphing calculator or an online solver. Using such a method, we find that:

x ≈ 9,932 meters

Therefore, the package should be released about 9,932 meters before the target to hit the target, rounded to the nearest meter.
