To calculate the probability of choosing tiles with the numbers 7, 8, and 9 in that specific order, we need to consider the number of favorable outcomes and the total number of possible outcomes.

First, let's determine the number of favorable outcomes. Since we are choosing three tiles without replacement, the first tile must be number 7, the second tile must be number 8, and the third tile must be number 9. There is only one way to arrange these three numbers in the specific order we want.

Next, let's calculate the total number of possible outcomes. When we choose the first tile, we have nine options (since there are nine tiles in total). After putting the first tile aside, we have eight remaining options for the second tile. Finally, for the third tile, we have seven options left.

Therefore, the total number of possible outcomes is 9 * 8 * 7 = 504.

Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:

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

= 1 / 504

≈ 0.0020

Converting this probability to a percentage to the nearest tenth, we get 0.2%.

Answer:

C

Step-by-step explanation:

3x - 9y = 9 → (1)

- 2x +2y = 8 ( subtract 2y from both sides )

- 2x = - 2y + 8 ( divide through by - 2 )

x = y - 4

substitute x = y - 4 into (1)

3(y - 4) - 9y = 9

3y - 12 - 9y = 9

- 6y - 12 = 9 ( add 12 to both sides )

- 6y = 21 ( divide both sides by - 6 )

y = \(\frac{21}{-6}\) = - \(\frac{7}{2}\)

Using the range rule of thumb, we can find the values within one standard deviation of the mean foot length. The range of values within one standard deviation of the mean foot length is between 26.99 cm and 29.25 cm.

A group of adult males has foot lengths with a mean of 28.12 cm and a standard deviation of 1.13 cm. In this question, we are given that a group of adult males has foot lengths. The given mean of foot lengths is 28.12 cm, and the standard deviation is 1.13 cm.

The range rule of thumb states that for a normal distribution, about 68% of the values will fall within one standard deviation of the mean, about 95% will fall within two standard deviations, and about 99.7% will fall within three standard deviations. Therefore, we can use the range rule of thumb to find the values within one standard deviation of the mean foot length.

Adding and subtracting one standard deviation to the mean value gives the range of values: (28.12 - 1.13) cm to (28.12 + 1.13) cm, which simplifies to 26.99 cm to 29.25 cm. The range of values within one standard deviation of the mean foot length is between 26.99 cm and 29.25 cm.

Therefore, using the range rule of thumb, we can find the values within one standard deviation of the mean foot length. The range of values within one standard deviation of the mean foot length is between 26.99 cm and 29.25 cm.

The division of the polynomial x^2 + 2*x - 6 by (x + 1), using the long division method of dividing polynomials is x + 1 - 7/(x + 1)

The long division method allows the division of large numbers (which is the dividend) into the number of groups of the divisor and a remainder which is a value less than the expressed value of the divisor.

The expression \_f_rac{x}{y} x^2 + 2*x - 6/x + 1 can be presented as follows;

The long division showing the steps can be obtained using code found online as follows;

\(\begin{array}{*1r {\arraycolsep}{\arraycolsep} *{11}l} & && x + 1 \\\cline{4-3}& &x+1& \longdiv {) x^2 +2\cdot x - 6& & & & & \\ & & & x^2 +x \\\cline{4-} && &\ \ \ x -6& \\ & & \ \ \ & \ \ \ x +1 \\\cline{4-} & & & \ \ \ \ \ \ \ -7 & \\ \cline{4-} \end{array}\)

The remainder of the long division is -7, therefore, we get;

\(\dfrac{x^2+2\cdot x-6}{x + 1} = x + 1 - \dfrac{7}{x+1}\)

The value of the expression, \_f_rac{x}{y} x^2 + 2*x - 6/x + 1 following the long division is; x + 1 - 7/(x + 1)

Step-by-step explanation:

Answer:

y=-1/4x+6

Step-by-step explanation:

Subtract x on both sides:

4y=-x+24

Divide 4 on both sides:

y=-1/4x+6

So the slope-intercept form for x+4y=24 is y=-1/4x+6

Graph of the slope below same line so the equation is the same so there are no problems with the equation

Hope this helps!

Answer:

y=-1/4x+6

Step-by-step explanation:

Answer:

34 degrees

Step-by-step explanation:

The equation of the tangent line to the function \(f(x) = -2x^3 - 4x^2 - 3x + 2\) at the point where x = -1 is y = -x + 6. The slope of the tangent line is -1, and the point of tangency is (-1, 7).

To find the equation of the tangent line to the function\(f(x) = -2x^3 - 4x^2 - 3x + 2\) at the point where x = -1, we need to determine both the slope of the tangent line and the point of tangency.

First, we find the derivative of the function f(x) to obtain the slope of the tangent line. The derivative of \(-2x^3 - 4x^2 - 3x + 2 is f'(x) = -6x^2 - 8x - 3\).

Next, we substitute x = -1 into the derivative to find the slope of the tangent line at x = -1: \(f'(-1) = -6(-1)^2 - 8(-1) - 3 = -6 + 8 - 3 = -1\).

Now, we have the slope of the tangent line, which is -1. To find the point of tangency, we substitute x = -1 into the original function f(x): \(f(-1) = -2(-1)^3 - 4(-1)^2 - 3(-1) + 2 = -2 + 4 + 3 + 2 = 7\).

Therefore, the point of tangency is (-1, 7), and the equation of the tangent line can be written in a point-slope form as y - 7 = -1(x - (-1)) or y - 7 = -1(x + 1).

In slope-intercept form, the equation simplifies to y = -x + 6.

Therefore, the equation of the tangent line to the function \(f(x) = -2x^3 - 4x^2 - 3x + 2\) at the point where x = -1 is y = -x + 6. The slope of the tangent line is -1, and the point of tangency is (-1, 7).

To determine which interval has the most confidence in capturing the population mean, we need to look at the confidence level associated with each interval. A confidence interval is a range of values that we believe contains the true population parameter.

If we have three intervals with different confidence levels, the interval with the highest confidence level would be the one with the most confidence in capturing the population mean. For example, if Interval A has a confidence level of 90%, Interval B has a confidence level of 95%, and Interval C has a confidence level of 99%, then Interval C would have the most confidence in capturing the population mean.

It's important to note that the level of confidence we choose affects the width of the interval. The higher the confidence level, the wider the interval will be. Therefore, we need to balance the desire for a high level of confidence with the need for a narrow interval.

In summary, the interval with the highest confidence level is the one with the most confidence in capturing the population mean. Confidence intervals are a powerful tool in statistics that allows us to estimate population parameters from a sample with a known degree of uncertainty.

Answer:

6 + 12/13, or 90/13 people will be served

Step-by-step explanation:

Ratios stay the same, no matter the quantity.

Given this, we can say that (13 grapes / 3 people) = (30 grapes / x amount of people)

13/3 = 30 / x

multiply both sides by 3 to remove a denominator

13 = 30 * 3 /x

multiply both sides by x to remove the other denonimator

13 * x = 30 * 3

13 * x = 90

divide both sides by 13 to isolate the x

x = 90/13 = 6 + 12/13 ≈6.92 people

The answer is 11/20.

The number of revolutions per minute the wheels are rotating is 2293 rpm (approximately).

Given, the speed of the car is 65 miles per hour and the diameter of the wheels is 2.5 feet.

To find: The number of revolutions per minute the wheels are rotating.

Formula used: We know that the distance traveled in one revolution (circumference of the circle) = π * diameter

Let "r" be the radius of the circle, so the diameter of the wheel is 2.5 feet.

Therefore, radius of the wheel r = 2.5/2 = 1.25 feet = 15 inches.

=> Circumference of the wheel = 2πr= 2*π*1.25 = 2.5π feet

In one mile there are 5280 feet.

So, the distance traveled by the car in one hour = 65 * 5280 feet/hour = 343200 feet/hour.

To find the number of revolutions in one minute, we will need to convert feet per minute (fpm).

Therefore, number of feet per minute = 343200/60 = 5720 feet per minute (fpm).

Now, we can calculate the number of revolutions per minute (rpm):

The number of revolutions per minute (rpm) = Feet per minute (fpm) / distance traveled in one revolution (circumference of the wheel)

=> rpm = fpm / Circumference of the wheel= 5720 / 2.5π= 2292.9 rpm (approximately)= 2293 rpm (approximately)

Therefore, the number of revolutions per minute the wheels are rotating is 2293 rpm (approximately).
