Answer:

75%

Step-by-step explanation:

We are given that Sara bought a chest for $42, and then sold it for $73.50.

Recall that when finding by how much something was marked up, you should use the following formula:

(new price-original price)/(original price)

Let's substitute the values, like so:

[tex]\frac{73.50-42}{42}=\\\\ \frac{31.50}{42}[/tex]

Now, set up a proportion to find what this fraction is as a percentage:

[tex]\frac{31.5}{42} =\frac{x}{100} =\\42x=3150=\\x=75[/tex]

So, the price was marked up by 75%.

The probability of selecting no Independents is $\frac{{7 \choose 2} + {8 \choose 2}}{{20 \choose 2}} = \frac{91}{190} \approx 0.4789$.

The surface area of the cylinder is approximately 94.2 ft².

Surface area refers to the total area of the external or outer part of an object. It is the sum of the areas of all the individual surfaces or faces of the object. Surface area is typically measured in square units, such as square inches (in²), square feet (ft²), or square meters (m²), depending on the unit of measurement used.

According to the given information:

The surface area of a cylinder is the sum of the lateral surface area (the curved surface) and the area of the two circular bases.

The formula for the lateral surface area of a cylinder is given:

Lateral Surface Area = 2πrh

where r is the radius of the cylinder and h is the height of the cylinder.

Plugging in the given values for the radius (r = 3 ft) and height (h = 2 ft), we can calculate the lateral surface area:

Lateral Surface Area = 2π * 3 * 2 = 12π ft²

The formula for the area of a circle (which represents the bases of the cylinder) is given:

Circle Area = πr²

Plugging in the given value for the radius (r = 3 ft), we can calculate the area of each circular base:

Circle Area = π * 3² = 9π ft²

Since there are two bases in a cylinder, we multiply this by 2 to account for both bases:

2 * Circle Area = 2 * 9π = 18π ft²

Now, we can add the lateral surface area and the area of the two bases to find the total surface area of the cylinder:

Total Surface Area = Lateral Surface Area + 2 * Circle Area

= 12π + 18π

= 30π ft²

As a decimal rounded to the nearest tenth, the surface area of the cylinder is approximately 94.2 ft²

This means that we can be 95% confident that the true population means examination score falls within this range based on the sample data.

The confidence interval estimate of the population means examination score can be calculated using the sample mean and the margin of error. The margin of error depends on the level of confidence and the sample size.

For example, if a sample of 100 applications provided a sample mean score of 80, and a 95% confidence level is used, the confidence interval estimate of the population mean examination score would be:

Margin of error = (critical value) x (standard error)

The critical value for a 95% confidence level with 99 degrees of freedom is 1.984. The standard error can be calculated using the formula:

Standard error = (standard deviation) / sqrt(sample size)

If the standard deviation of the examination scores is known, it can be used in the formula. If not, the sample standard deviation can be used as an estimate.

Assuming a sample standard deviation of 10, the standard error would be:

[tex]Standard\  error = \frac{10} { \sqrt{(100)}} = 1[/tex]

Therefore, the margin of error would be:

Margin of error = 1.984 x 1 = 1.984

The confidence interval estimate of the population means examination score would be:

80 ± 1.984, or between 78.016 and 81.984.

To determine the confidence interval estimate of the population mean examination score based on a sample mean

provided to the nearest whole number, we need to know the sample size and the level of confidence.

Assuming a normal distribution and a level of confidence of 95%, we can use the following formula to calculate the

confidence interval estimate:

Confidence interval = sample mean +/- (critical value) x (standard error)

The critical value can be found using a t-distribution table or a calculator, based on the sample size and degrees of

freedom (n-1). For a sample size of 30 or more, we can use the z-score instead of the t-score.

The standard error is the standard deviation of the sample divided by the square root of the sample size.

For example, if a sample of 50 applications provided a sample mean of 75, and the standard deviation was 10, the

standard error would be 10/sqrt(50) = 1.41.

Assuming a level of confidence of 95%, the critical value for a sample size of 50 and degrees of freedom of 49 would be 1.96.

To determine if each ordered pair is a point of intersection between the line x - y = 6 and the circle y² - 26 = -x², we need to substitute the values of x and y in both equations and see if they are true for both.

For the ordered pair (1, -5):

x - y = 6 becomes 1 - (-5) = 6, which is true.

y² - 26 = -x² becomes (-5)² - 26 = -(1)², which is false.

Therefore, (1, -5) is not a point of intersection.

For the ordered pair (1, 5):

x - y = 6 becomes 1 - 5 = -4, which is false.

y² - 26 = -x² becomes (5)² - 26 = -(1)², which is true.

Therefore, (1, 5) is a point of intersection.

For the ordered pair (5, -1):

x - y = 6 becomes 5 - (-1) = 6, which is true.

y² - 26 = -x² becomes (-1)² - 26 = -(5)², which is false.

Every day, the number of views of the video increases by 80% of the previous day's views.

Every day, the number of views of the video increases by a certain percentage. To find the daily percent change in the views, we can use the formula for percent change, which is given by:

percent change = ((new value - old value) / old value) * 100

In this case, the old value is the number of views at the start, which is 500, and the new value is the number of views after one day, which is given by:

V(1) = 500*(1.8)^1 = 900

Substituting these values into the formula, we get:

percent change = ((900 - 500) / 500) * 100 = 80%

The radian measure of the center angle corresponding to the arc length of 10 centimeters is 2 radians.

An arc is a segment of a curve or a curved line that is a part of a circle, an ellipse, or any other curved shape. In geometry, arcs are important because they define a portion of the circumference of a circle or an ellipse.

An arc is defined by two endpoints on the curve and the points on the curve between the endpoints. The length of an arc is measured as the distance along the curve between the two endpoints. The measure of an arc is often expressed in terms of degrees or radians.

In a circle, an arc is a part of the circumference of the circle, and it is named based on the two endpoints of the arc. For example, if AB is an arc of a circle with endpoints A and B, then it can be denoted as arc AB or arc BA.

An arc can be measured in terms of its central angle, which is the angle formed by the two radii that define the endpoints of the arc and the center of the circle. The measure of the central angle of an arc is directly proportional to the length of the arc. In other words, if two arcs have central angles that are equal, then their lengths are also equal.

The radian measure of the center angle corresponding to an arc length of a circle is given by the formula:

θ = s/r

where θ is the radian measure of the center angle, s is the length of the arc, and r is the radius of the circle.

In this case, the radius of the circle is given as 5 centimeters, and the length of the arc is given as 10 centimeters. Substituting these values into the formula, we get:

θ = 10/5 = 2 radians

The statement that is true about Evan's expression is that it represents a linear function of the amount of medicine in his bloodstream, where the initial amount is 100 milligrams and the rate of change is -0.4 milligrams per minute.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

The expression 100 - 0.4m represents the amount of medicine in Evan's bloodstream after m minutes, where the amount of medicine decreases by 0.4 milligrams each minute.

The coefficient of the variable m (-0.4) represents the rate of change of the amount of medicine in Evan's bloodstream per minute. It tells us that for every one minute that passes, the amount of medicine in his bloodstream decreases by 0.4 milligrams.

The constant term (100) represents the initial amount of medicine in Evan's bloodstream before the medicine starts to decrease.

The formula for the general term of the arithmetic sequence is:

a) an = -10 + (n-1) * 6 and first-term = -10

b) an = -10 + (n-1) * 6 and first-term = 6

c) an = 36 + (n-1) * (-5) and first-term = 36

An arithmetic sequence is a sequence of numbers in which each term (after the first) is obtained by adding a fixed number called the common difference, d, to the preceding term. The first term of an arithmetic sequence is denoted by 'a'. The general formula for an arithmetic sequence is:

a, a + d, a + 2d, a + 3d, ...

where 'a' is the first term, 'd' is a common difference, and each term after the first is obtained by adding 'd' to the preceding term.

a) To find the common difference, we subtract any term from the term that comes after it. For example, we can subtract -10 from -4, or 2 from 8, and we get:

-4 - (-10) = 6

8 - 2 = 6

Since both of these subtractions give us the same result, we know that the common difference is d = 6. To find the first term, we can use any term and subtract the product of the common difference and its position in the sequence minus 1. For example, we can use the second term -4 and its position 2 to get:

a = -4 - (2-1) * 6 = -10

Therefore, the formula for the general term of the sequence is:

an = -10 + (n-1) * 6

b) The common difference between consecutive terms is -2 because each term is 2 less than the term before it. To find the first term, we can use any term and add the product of the common difference and its position in the sequence minus 1. For example, we can use the second term 8 and its position 2 to get:

a = 8 + (2-1) * (-2) = 6

Therefore, the formula for the general term of the sequence is:

an = 6 + (n-1) * (-2)

c) The common difference between consecutive terms is -5 because each term is 5 less than the term before it. To find the first term, we can use any term and add the product of the common difference and its position in the sequence minus 1. For example, we can use the second term 31 and its position 2 to get:

a = 31 + (2-1) * 5 = 36

The area of the region R is 4/3 square unit, while the value of c is 2 - √3.

To find the value of c for which the two subregions have the same area, we need to first find the points of intersection of the given curves.

Setting y = 2x - x^2 = 0, we get x = 0 and x = 2. So the curves intersect at the points (0,0) and (2,0).

Now, we can set up the integral to find the area of the region R:

A = ∫[0,2] (2x - x^2) dx

A = [x^2 - (x^3/3)]|[0,2]

A = (4/3) square units

Next, we need to find the value of c for which the two subregions of R have the same area. Let (a, 2a - a^2) be the point where the line y = cx intersects the curve y = 2x - x^2.

So we have:

2a - a^2 = ca

Rearranging, we get:

a^2 - 2a + c = 0

Using the quadratic formula, we get:

a = (2 ± √(4 - 4c))/2 = 1 ± √(1 - c)

Since a > 0, we must choose the positive root.

Now, we can set up the integrals to find the areas of the two subregions of R:

A1 = ∫[0,a] (2x - x^2 - cx) dx

A2 = ∫[a,2] (2x - x^2 - cx) dx

Setting A1 = A2, we get:

∫[0,a] (2x - x^2 - cx) dx = ∫[a,2] (2x - x^2 - cx) dx

Solving for c, we get:

c = (2a - a^2)/(2a - 2)

Substituting a = 1 + √(1 - c), we get:

c = 2 - √3

Therefore, the value of c for which the two subregions of R have the same area is 2 - √3.

The value of cos ( 90 - x ), given the side lengths of the right triangle would be B. 3 / 5.

In a right triangle, the sum of the two acute angles is always 90 degrees. If we have a right triangle with side lengths 3, 4, and 5, then it's a 3-4-5 Pythagorean triple, which means the angles are also in a specific ratio.

Now, we want to find cos(90 - x). Since the sum of the two acute angles in a right triangle is 90 degrees, the other angle in the triangle is (90 - x). We know that sin x = opposite / hypotenuse, so in our triangle, sin(90 - x) = 3/5.

The sine and cosine of complementary angles are related by the co-function identity:
