The shaded area of the circle sector can be found by using the formula mentioned below. Area of Sector = (θ/360) × πr² Where  = the central angle of the sector and r = the radius of the circle,  = 3.14. By substituting the given values in the formula, we get: 100°r = 6 inches = 3.14.

We need to convert the central angle from degrees to radians, as the formula for area of a sector requires the value in radians. Radian measure = degree measure  /180 = 100  3.14/180 = 1.745 radians. Area of Sector = (/360)  r2 = (1.745/2)  3.14  62 = 15.3 square inches. The shaded area of the circle sector can be found by using the formula mentioned below. Area of Sector = (θ/360) × πr² Where,θ = Central angle of the sector r = Radius of the circle = 3.14. By substituting the given values in the formula, we get,θ = 100°r = 6 inches π = 3.14. We need to convert the central angle from degrees to radians, as the formula for area of a sector requires the value in radians. Radian measure = degree measure  /180 = 100  3.14/180 = 1.745 radians. Now, let us substitute the values in the formula to find the area of the sector. Area of Sector = (/360)  r2 = (1.745/2)  3.14  62 = 15.3 square inches. Therefore, the shaded area of the circle sector is 15.3 square inches (approx).

In conclusion, we can say that the area of the shaded region in the circle sector can be calculated by using the formula for the area of the sector.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

Answer:

  100 m²

Step-by-step explanation:

The scale factor for volume of similar figures is the cube of the scale factor for linear dimensions. The scale factor for area is the square of that linear dimension scale factor.

If the ratio of volumes is the cube of the scale factor, then the scale factor for the smaller figure in terms of the larger is ...

  \(k=\sqrt[3]{\dfrac{125\text{ m}^3}{729\text{ m}^3}}=\sqrt[3]{\dfrac{5^3}{9^3}}=\dfrac{5}{9}\)

The area of the smaller figure is found from ...

  \(\dfrac{A}{324\text{ m}^2}=\left(\dfrac{5}{9}\right)^2=\dfrac{25}{81}\\\\A=(324\text{ m}^2)\cdot\dfrac{25}{81}=\boxed{100\text{ m}^2}\)

The surface area of the smaller solid is 100 square meters.

(x, y) = (-8, 19)

Step-by-step explanation:

9x + 3y = -15

-4x - 3y = -25

(9x + 3y) + ((-4x) - 3y) = -15 + (-25)

5x = -40

x = -8.

So,

9x + 3y = -15

9 * (-8) + 3y = -15

-72 + 3y = -15

3y = 57

y = 19

The modal class of time spent exercising from the table that shows the time spent exercising, is 40 < x ≤ 50.

The class that the median lies is 30 < x ≤ 40.

The modal class would be the one that has the highest frequency which is the class that has the most time spent exercising. That class is the 40 < x ≤ 50 class with 21 people.

The class in which the median lies is the middle class and we need to find the total first:

Answer:

31 years

Step-by-step explanation:

65000*(1.07) ^31 is around $529000

however, 65000*(1.07) ^30 is around $491000

so you would need 31 years to gain more than $500,000.

It will take approximately 30 years to reach $500,000 in savings with an investment that earns an average of 7% per year.

To determine the number of years it will take to reach $500,000 in savings with an investment that earns an average of 7% per year, we can use the given investment model equation: y = 65000(1.07)ˣ.

We need to find the value of x, which represents the number of years.

Setting y = $500,000, we can solve for x:

500,000 = 65,000(1.07)ˣ

500,000/65,000 = (1.07)ˣ

100/13 = (1.07)ˣ

To solve for x, we take the logarithm of both sides:

ln 100/13 = ln (1.07)ˣ

ln 100/13 = x ln (1.07)

x = (ln 100/13)/(ln (1.07))

x = 30

Therefore, it will take approximately 30 years to reach $500,000 in savings with an investment that earns an average of 7% per year.

Let's start with the question at hand before providing an answer: Jason is interested in determining whether people who smoke require less sleep than non-smokers, who require an average of 7.5 hours per night with a population standard deviation of 0.7 hours. What is the z-score if the sample mean is 7.2 hours? The correct answer is -3.32.

To find the z-score, we use the formula:

z = (x - μ) / (σ / sqrt(n))

where n is the sample size, x is the sample mean, μ is the population mean, and σ is the population standard deviation.

In this instance, n = 60, x = 7.2 hours,  = 7.5 hours, and  = 0.7 hours.

When we enter the values, we obtain:

z = (7.2 - 7.5) / (0.7 / sqrt(60))

z = -0.3 / (0.0907)

z = -3.31

Rounding to two decimal places, we get z = -3.32.

Therefore, the z-score is -3.32.

The probability that it will take more than four draws until the third shiny penny appears is 2/5. Let A denote the event that it will take more than four draws until the third shiny penny appears.

Let X denote the number of dull pennies that are drawn before the third shiny penny appears.

Then, X follows a negative hypergeometric distribution with parameters N = 7 (total number of pennies), M = 3 (number of shiny pennies), and n = 3 (number of shiny pennies needed to be drawn).

The probability mass function of X is given by:

P(X = k) =\({{k+2} \choose {k}} / {{6} \choose {3}}\)  for k = 0, 1, 2.

Note that k + 3 is the number of draws needed until the third shiny penny appears.

Thus, we have:

P(A) = P(X > 1) = P(X = 2) + P(X = 3)

=\({{4} \choose {2}} / {{6} \choose {3}} + {{5} \choose {3}} / {{6} \choose {3}}\)

= 6/20 + 10/20= 8/20= 2/5

The probability that it will take more than four draws until the third shiny penny appears is 0.057, or 5.7%.

To find the probability that it will take more than four draws until the third shiny penny appears, we can use the concept of combinations and probability.

First, let's determine the total number of ways to draw 3 shiny pennies and 4 dull pennies in any order. This can be calculated using the formula for combinations:

\(\[C(n, r) = \frac{{n!}}{{r!(n-r)!}}\]\)

In this case, we have a total of 7 pennies (3 shiny and 4 dull), and we want to choose 3 shiny pennies. So, we can calculate C(7, 3) as follows:

\(\[C(7, 3) = \frac{{7!}}{{3!(7-3)!}} = \frac{{7!}}{{3!4!}} = \frac{{7 \cdot 6 \cdot 5}}{{3 \cdot 2 \cdot 1}} = 35\]\)

So, there are 35 different ways to draw 3 shiny pennies from the box.

Now, let's consider the different scenarios in which it will take more than four draws until the third shiny penny appears. We can break this down into three cases:

Case 1: The third shiny penny appears on the 5th draw.
In this case, we have 4 dull pennies and 2 shiny pennies to choose from for the first 4 draws. The third shiny penny must appear on the 5th draw. So, the probability for this case is:

\(P(case 1) = (4/7) \times (3/6) \times (2/5) \times (1/4) \times (2/3) = 0.019\)

Case 2: The third shiny penny appears on the 6th draw.
In this case, we have 4 dull pennies and 2 shiny pennies to choose from for the first 5 draws. The third shiny penny must appear on the 6th draw. So, the probability for this case is:

\(P(case 2) = (4/7) \times (3/6) \times (2/5) \times (1/4) \times (2/3) \times (1/2) = 0.019\)

Case 3: The third shiny penny appears on the 7th draw.
In this case, we have 4 dull pennies and 2 shiny pennies to choose from for the first 6 draws. The third shiny penny must appear on the 7th draw. So, the probability for this case is:
\(P(case 3) = (4/7) \times (3/6) \times (2/5) \times (1/4) \times (2/3) \times (1/2) \times (1/1) = 0.019\)

Finally, to find the probability that it will take more than four draws until the third shiny penny appears, we sum up the probabilities of all three cases:
P(more than four draws until third shiny penny appears) = \(P(case 1) + P(case 2) + P(case 3) = 0.019 + 0.019 + 0.019 = 0.057\)

Therefore, the probability that it will take more than four draws until the third shiny penny appears is 0.057, or 5.7%.

True. The variables x, y, and z have each been assigned an integer value.

Here is a fragment of code that assigns the least of three integer variables to another variable named min:

min = x  # initialize min to the value of x

if y < min:  # check if y is less than min

   \(min = y\) # \(update min to the value of y if y is less than min\)

if z < min:  # check if z is less than min

   \(min = z\) # \(update min to the value of z if z is less than min\)

In this code, the variable 'min' is first initialized to the value of 'x'. Then, the code checks if 'y' is less than 'min', and if so, updates the value of 'min' to 'y'. Finally, the code checks if 'z' is less than 'min', and if so, updates the value of 'min' to 'z'. At the end of this code fragment, the variable 'min' will contain the least of the three variables 'x', 'y', and 'z'.
