The cash back you would receive on your purchases of $2,738.21 using this credit card is $33.92.

To calculate the cash back you would receive using the given credit card, we need to multiply the total amount spent in each category by the corresponding cash back percentage, and then add up those amounts.

For gas purchases, you spent $134.92, so the cash back earned on that amount would be:

$134.92 x 3% = $4.05

For grocery store purchases, you spent $384.23, so the cash back earned on that amount would be:

$384.23 x 2% = $7.68

For all other purchases, you spent a total of:

$2,738.21 - $134.92 - $384.23 = $2,219.06

So the cash back earned on that amount would be:

$2,219.06 x 1% = $22.19

Adding up the cash back earned in each category, we get:

$4.05 + $7.68 + $22.19 = $33.92

∴ Cashback = $33.92

The final triangle has vertices at (3, -1), (3, -4), and (1, -4) on the graph.

In mathematics, a transformation refers to a function that maps points or shapes in one coordinate system to corresponding points or shapes in another coordinate system, while preserving certain properties such as size, shape, orientation, and distance.

Starting with the triangle on a graph with vertices at (-4, 4), (-4, 1), and (-2, 1), we can apply the given transformations as follows:

Go right 1 and down 5: This transformation corresponds to the function T(x, y) = (x + 1, y - 5). Applying this function to each vertex of the triangle, we get:

(-4, 4) -> (-3, -1)

(-4, 1) -> (-3, -4)

(-2, 1) -> (-1, -4)

Reflect on the y-axis: This transformation corresponds to the function R(x, y) = (-x, y). Applying this function to each vertex of the transformed triangle, we get:

(-3, -1) -> (3, -1)

(-3, -4) -> (3, -4)

(-1, -4) -> (1, -4)

Therefore, the final triangle has vertices at (3, -1), (3, -4), and (1, -4) on the graph.

Given that AB is a diameter. |BC| = |CD| and AÔD = 64°, The angles  of the quadrilateral ABCD is 90 degrees

Since |BC| = |CD|, we know that triangle BCD is an isosceles triangle.

Since triangle BCD is isosceles, angles BDC and CBD are equal. Let's call each of these angles x.

180 - 64

= 116 degrees

angle BCD = 180 - 116

Calculation:Let x, x + 2, x + 4 be the three consecutive odd integers.

Sum of three consecutive odd integers = 39

⇒ x + (x + 2) + (x + 4) = 39

⇒ 3x + 6 = 39

⇒ 3x = 33

⇒ x = 11

∴ The integers are 11, 13 and 15.

∴ Their product = 11 × 13 × 15 = 2145

The percent increase when [tex]$x$[/tex] increases by one unit is approximately 15.8%.

What is exponential function?

An exponential function is a mathematical function of the form:

[tex]f(x) = a^x[/tex]

where a is a constant greater than zero and not equal to 1, and x is the variable that takes on real numbers.

To find the percent increase for the exponential function [tex]$A = 82\times 1.16^x$[/tex], we need to find the ratio of the final value to the initial value, subtract one, and then multiply by 100 to convert to a percentage.

Let's suppose we are interested in finding the percent increase when [tex]$x$[/tex] increases by one unit. We can start by calculating the initial value of [tex]$A$[/tex] when [tex]$x = 0$[/tex]:

[tex]$$A = 82 \times 1.16^0 = 82$$[/tex]

Then we can calculate the final value of [tex]$A$[/tex] when [tex]$x = 1$[/tex]:

[tex]$$A = 82 \times 1.16^1 \approx 95.12$$[/tex]

Now we can find the ratio of the final value to the initial value:

[tex]$\text{ratio} = \frac{\text{final value}}{\text{initial value}} = \frac{95.12}{82} \approx 1.158$$[/tex]

Next, we subtract one and multiply by 100 to get the percent increase:

[tex]$$\text{percent increase} = (\text{ratio} - 1) \times 100 \approx (1.158 - 1) \times 100 \approx 15.8%$$[/tex]

Therefore, the percent increase when [tex]$x$[/tex] increases by one unit is approximately 15.8%.

1. sin ² x goes in the numerator. 2. sin x (sin x) is the numerator expanded. 3. Separate the two factors sin x / cos x and sin x / cos x. 4. Replace sin x / cos x with tan x. Use the trigonometric identity.

Simply put, trigonometric functions—also referred to as circular functions—are the functions of a triangle's angle. This means that these trig functions provide the connection between the angles and sides of a triangle. The three basic categories of trigonometric functions are sine, cosine, and tangent. In contrast to the fundamental trigonometric functions, the other three functions are essentially employed more frequently. For an explanation of these three main roles, use the diagram below as a guide. The sin-cos-tan triangle is the name for this illustration. Often, the right-angled triangle is used to define trigonometry.

The given trigonometric function is 1 / cos x csc² x.

Now, the csc²x can be written as:

sin²x / cos x. Thus, sin ² x goes in the numerator.

Now, sin x (sin x) is the numerator expanded.

Separate the two factors sin x / cos x and sin x / cos x

Replace sin x / cos x with tan x.

The equation of the line from the given graph is y = 3x + 1.

With the aid of the line's slope and a point on the line, the equation of a line may be created. For a better understanding of how a line's equation is created, let's learn more about the line's slope and the necessary point on the line. The slope of a line is the angle that the line makes with the positive x-axis and can be stated as a numerical integer, fraction, or as the tangent of that angle. The term "point" refers to a coordinate system point with the x and y coordinates.

From the given graph we observe the two coordinates of the line are (0, 1) and (3, 10).

The slope of the line is given as:

m = y2 - y1 / x2 - x1

m = (10 - 1) / (3 - 0)

m = 9/3 = 3

The point-slope intercept is given as:

y - y1 = m (x - x1)

Substituting the values:

y - 1 = 3 (x - 0)

y - 1 = 3x

y = 3x + 1

Yes, the ratio of the hypotenuse to a leg is the same for all isosceles right triangles.

What is hypotenuse ?

In a right triangle, the hypotenuse is the side that is opposite to the right angle. It is also the longest side of the triangle. The hypotenuse is always opposite the right angle and is found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. In a right triangle with legs of length "a" and "b", the length of the hypotenuse "c" can be found using the formula:

[tex]c^2 = a^2 + b^2[/tex]

Taking the square root of both sides gives us:

[tex]c = \sqrt{a^2 + b^2}[/tex]

The hypotenuse plays an important role in trigonometry, as it is used in the calculation of trigonometric ratios such as sine, cosine, and tangent.

According to the question:
Yes, the ratio of the hypotenuse to a leg is the same for all isosceles right triangles.

In an isosceles right triangle, the two legs are congruent, which means they have the same length. Let's call the length of each leg "a". The hypotenuse of the triangle can be found using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs:

[tex]hypotenuse^2 = a^2 + a^2 = 2a^2[/tex]

Taking the square root of both sides, we get:

[tex]hypotenuse = \sqrt{2a^2} = a * \sqrt{2}[/tex]

So, the ratio of the hypotenuse to a leg is:

[tex]hypotenuse / a = (a * \sqrt{2}) / a = \sqrt{2}[/tex]

This shows that the ratio of the hypotenuse to a leg in an isosceles right triangle is always equal to the square root of 2, which is a constant value. Therefore, the ratio is the same for all isosceles right triangles.

By answering the presented question, we may conclude that As a result, probability the chance of receiving heads and 4 is 1/12.

Probability is a measure of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing a rare event and 1 representing an inescapable event. Switching a fair coin and coin flips has a chance of 0.5 or 50% since there are two equally likely outcomes. (Heads or tails). Probabilistic theory is an area of mathematics that studies random events rather than their attributes. It is applied in many disciplines, including statistics, economics, science, and engineering.

Here is an example space diagram that depicts all of the possible outcomes when Leo flips a coin and rolls a dice:

Each row represents the outcome of rolling the dice, and each column indicates the outcome of flipping the coin. The table entries represent the combined outcome of rolling the dice and flipping the coin. For example, the occurrence of receiving heads on the coin flip and rolling a 1 on the dice is represented by the outcome in the top left corner (H1).

As a result, the chance of receiving heads and 4 is 1/12.

The exact value of the cosine of angle A + B is equal to - 1239 / 1961.

In this problem we need to determine the exact value of a trigonometric function, this can be done by using definitions of trigonometric functions, Pythagorean theorem and trigonometric formulas:

Trigonometric function

sin θ = y / r

cos θ = x / r

tan θ = y / x

Pythagorean theorem

r² = x² + y²

Trigonometric formula

cos (A + B) = cos A · cos B - sin A · sin B

First, determine the exact values of sines and cosines:

Angle A

r = √(28² + 45²)

r = 53

sin A = 45 / 53

cos A = 28 / 53

Angle B

y = √(37² - 12²)

y = 35

sin B = 35 / 37

Second, calculate the exact value of the trigonometric function by trigonometric formula:

cos (A + B) = (28 / 53) · (12 / 37) - (45 / 53) · (35 / 37)

The sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 98% confidence level with an error of at most 0.03 is approximately 904

Since the commission wants a 98% confidence level, the z-score associated with that level is 2.33 (which can be found using a standard normal distribution table).

We also know that the commission wants an error of at most 0.03, so we can set up an equation:

0.03 = 2.33 x √(0.23 x 0.77) / √(n)

Solving for n, we get:

n = (2.33 x √(0.23 * 0.77) / 0.03)²

n = 903.78

So, the commission would need a sample size of at least 904 tenth grade students in order to estimate the fraction of students with reading skills at or below the eighth grade level at the 98% confidence level with an error of at most 0.03.

Wendy's conclusion is invalid as she cannot generalize her findings as sample size is too small to represent the entire school population accurately.

Wendy's assessment is incorrect. This is due to the fact that she is unable to extrapolate from a sample of just 40 students who play football for the school. The sample size is insufficient to provide an accurate representation of the student body as a whole. Also, the football players might be more prone to injuries than those who don't participate in sports, which could further skew the results.

Moreover, Wendy did not choose the football team members using a random sample approach. Instead, she restricted her questions to those students who were already on the football team, thereby introducing sample bias. She might have unintentionally left out pupils who don't participate in athletics but may nonetheless have hurt themselves while doing other physical activities.

Wendy's assertion that 375 of the school's 1,000 kids have sustained sports-related injuries is therefore unfounded. Wendy would need to employ a more representative and random sampling technique that includes students from various sports teams as well as those who do not play sports in order to draw a reliable conclusion.

The method that is most appropriate when calculating margin-of-error for population mean is (b) Student's t-distribution.

When calculating the margin of error for the population mean, the most appropriate method depends on the sample size.

If the sample size is large (n > 30) and the population standard deviation is known, then a normal z-distribution can be used to calculate the margin of error.

If the sample size is small (n < 30) or the population standard deviation is unknown, then Student’s t-distribution should be used to calculate the margin of error.

In this case, we are told that the information was obtained from 14 strands of this particular virus. Since n < 30, we should use Student’s t-distribution to calculate the margin of error.
