Denise goes to work with her father. She notices that one man worked 31 1\ 4 hours for the week, and he was paid $9.20 per hour. How much was the man's paycheck, before taxes?

Answer:

3330.08 inches of 277.51 feet

Step-by-step explanation:

13.25X2X3.14159=length of one rotation=83.25

40 rotations=40(83.25)=3330.08 inches

The standard score for the distribution with mean at the height of 6 feet or 72 inches is 1.12.

The normal distribution of height of men is approximately normal with mean 69.2 inches and standard deviation of sigma=2.5 inches

According to the empirical rule of probability, about 95% observations falls within two standard deviation of mean.

Therefore,

Lower bound=μ + 2×σ

=69.2 + 2×2.5

=69.2 + 5.0

Lower bound = 74.2

Upper bound = μ - 2 × sigma

=69.2 - 5

Upper bound = 64.2

2. The distribution of the heights of young men is approximately normal with mean μ = 69.2 inches and standard deviation of σ = 2.5

The standard score of height of 72 inches is calculated by:

z = (72-69.2)/2.5

z = 2.8/2.5

z = 1.12

Therefore the standard score for the distribution with mean at the height of 6 feet or 72 inches is 1.12.

Answer:

whats the question

Step-by-step explanation:

The given expression consists of several mathematical series representing different functions, such as exponential, sine, cosine, and arctangent functions.

For f(x) = 5e^x + e^(5x), e^x can be represented as an infinite series using the power series expansion: e^x = 1 + x + (x^2)/2! + (x^3)/3! + ...
Similarly, sine and cosine functions have their respective Maclaurin series expansions:
sin(x) = x - (x^3)/3! + (x^5)/5! - (x^7)/7! + ...
cos(x) = 1 - (x^2)/2! + (x^4)/4! - (x^6)/6! + ...
The arctangent function can be represented as an alternating series:
tan^(-1)(x) = x - x^3/3 + x^5/5 - x^7/7 + ...
Lastly, the binomial expansion of (1+x)^k has its own series representation:
(1+x)^k = 1 + kx + k(k-1)(x^2)/2! + k(k-1)(k-2)(x^3)/3! + ...
The expressions with R=[infinity] signify that these series are convergent for all real numbers x within their radius of convergence.

Solving the provided question, we can say that the value inequality equation we have is x≥4

An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

Step-by-step explanation:

4) \(A_{QRST} = A_{Q'R'S'T'} = 9\).

5) The areas of the rectangles QRST and Q'R'S'T' are the same since the translation of the geometric loci conserved the Euclidean distance.

6) x = 1, w = 3, y = - 1/4, z = 1/3

Rigid transformations are transformations applied on geometric loci such that Euclidean distance is conserved. In this question we have applications of translations, a kind of rigid transformation.

Exercise 4

In this part we must determine the areas of rectangles QRST and Q'R'S'T':

Rectangle QRST

A = RS · QT

A = 3 · 3

A = 9

Rectangle Q'R'S'T'

Q'(x, y) = (2, - 3) + (- 3, - 3)

Q'(x, y) = (- 1, - 6)

R'(x, y) = (2, 4) + (- 3, - 3)

R'(x, y) = (- 1, 1)

S'(x, y) = (5, 4) + (- 3, - 3)

S'(x, y) = (2, 1)

T'(x, y) = (5, - 3) + (- 3, - 3)

T'(x, y) = (2, - 6)

A = R'S' · Q'T'

A = 3 · 3

A = 9

The rectangles QRST and Q'R'S'T' have both an area of 9 square units.

Exercise 5

The areas of the rectangles QRST and Q'R'S'T' are the same since the translation of the geometric loci conserved the Euclidean distance.

Exercise 6

In this case, we must solve the following equations:

PQ = A'(x, y) - A(x, y)

(4, 1) = (2 · x + 1, 4) - (- 1, w)

(4, 1) = (2 · x + 2, 4 - w)

(4, 1) = (2 · x, - w) + (2, 4)

(2, - 3) = (2 · x, - w)

(x, w) = (1, 3)

PQ = B'(x, y) - B(x, y)

(4, 1) = (3, 3 · z) - (8 · y - 1, 1)

(4, 1) = (2 - 8 · y, 3 · z)

(4, 1) = (- 8 · y, 3 · z) + (2, 0)

(2, 1) = (- 8 · y, 3 · z)

(y, z) = (- 1/4, 1/3)

Without the probability distribution, it is not possible to calculate the standard deviation accurately. Thus, none of the provided options can be considered correct without additional information.

To calculate the standard deviation of the returns, we need the probability distribution of the holding-period returns and their corresponding values. Since the probability distribution is not provided in your question, it is not possible to determine the standard deviation.

To calculate the standard deviation, you would typically need the individual returns and their corresponding probabilities. With that information, you can use the formula for calculating the weighted standard deviation:

σ = √[∑(Ri - E(R))^2 * P(Ri)],

where Ri represents the individual returns, E(R) is the expected return, and P(Ri) is the probability of each return.

Without the probability distribution, it is not possible to calculate the standard deviation accurately. Thus, none of the provided options can be considered correct without additional information.

Answer:

$400

Step-by-step explanation:

Answer:

400$

Step-by-step explanation:

A random sample of 16 statistics examinations from a large population was taken. The test statistic (t) for this hypothesis test is 1.8.

To determine whether the average grade of the population is significantly more than 75, we can perform a hypothesis test using the given sample data. We'll set up the null and alternative hypotheses as follows:

Null Hypothesis (H 0): The average grade of the population is not significantly more than 75.

Alternative Hypothesis (Ha): The average grade of the population is significantly more than 75.

To conduct the hypothesis test, we can use the t-test since the population variance is unknown. Here, we'll assume the sample is representative and the Central Limit Theorem applies.

To calculate the test statistic for this hypothesis test, we will use the t-distribution since the population standard deviation is unknown. The formula for the t-test statistic is as follows:

t = (sample mean - hypothesized mean) / (sample standard deviation / √(sample size))

Given the information:

Sample mean (x) = 78.6

Hypothesized mean (μ) = 75

Sample standard deviation (s) = √(variance) = √(64) = 8

Sample size (n) = 16

Let's calculate the test statistic using the formula:

t = (78.6 - 75) / (8 / √(16))

t = 3.6 / (8 / 4)

t = 3.6 / 2

t = 1.8

Complete Question:

A random sample of 16 statistics examinations from a large population was taken. The average score in the sample was 78.6 with a variance of 64. We are interested in determining whether the average grade of the population is significantly more than 75. Assume the distribution of the population of grades is normal.

How do you get the test statistic?

Based on the information given in the question, it is not clear whether the city locations are sampled uniformly at random from all the locations in the U.S. In order for a sampling method to be considered uniformly random, each possible location would have an equal chance of being chosen. Without additional information about how the locations were chosen, it is difficult to determine if the sample is truly random and uniform.

The expression that most accurately describes the change in the patient's temperature is -2° (3).

Option 3 is the correct answer.

We have,

The expression that most accurately describes the change in the patient's temperature would be:

-2° + (-2°) + (-2°)

This expression represents the successive temperature drops of 2° each time.

By adding the negative values, we account for the decrease in temperature.

This can be written as,

= -2° x 3

= -2° (3)

Thus,

The expression that most accurately describes the change in the patient's temperature is -2° (3).

In summary, to find an interval of length 1 and having integer endpoints on which the function has a root, we can use a trial-and-error method to identify intervals that satisfy the given criteria. The choice of interval may depend on the specific function and there may be multiple intervals that satisfy these conditions.

To find an interval on which the function has a root, we need to consider the function's behavior and identify any potential zero crossings. An interval of length 1 with integer endpoints can be represented as [a, a+1] where a is an integer.
One approach to finding a root is to plot the function and visually identify where it crosses the x-axis. Another approach is to use algebra and solve for when the function equals zero. However, without knowing the specific function, we cannot use these methods.
Instead, we can use a trial-and-error method to identify an interval that satisfies the given criteria. For example, we can start by choosing an integer a and evaluating the function at a and a+1. If the function has opposite signs at these two endpoints, then by the Intermediate Value Theorem, the function must have at least one root in the interval [a, a+1].
We can continue this process until we find an interval that satisfies the given criteria. Note that there may be multiple intervals that satisfy these conditions, and the choice of interval may depend on the specific function.

Answer:

$375.32

Step-by-step explanation:

100% - 40% = 80%

80/100 = 0.8 (multiplier)

521.28 x 0.8 = 417.024

417.024 to 417.02 (2 d.p.)

100 - 10 = (ans)/100 = 0.9

417.02 x 0.9 = 375.318

$375.32

Step 1: Find the sales price

The surfboard was marked down 40% of its original price, $521.28.

0.40(521.28) = 208.512

521.28 - 208.512 = 312.768

Step 2: Find the final price

We add the tax on the sales price, not the original price. The tax is 10% in this case.

0.10(312.768) = 31.2768

312.768 + 31.2768 = 344.0448

Final price = $344.04

---I did not round until the end in this case, but rounding at every step leads to an answer of $344.05
