Answer:

380 seconds

Step-by-step explanation:

Convert 6 minutes to seconds by multiplying 6 times 60, because there are 60 seconds per minute.
6 x 60 = 360

Now add the 20 seconds.
360 + 20 = 380

6 minutes and 20 seconds are equal to 380 seconds.

Step-by-step explanation:

It is saying to subtract 3 from the product of 2 and the variable, y.

Step-by-step explanation: This simple confidence interval calculator uses a Z statistic and sample mean (M) to generate an interval estimate of a population mean (μ).

Note: You should only use this calculator if (a) your sample size is 30 or greater; and/or (b) you know the population standard deviation (σ), and use this instead of your sample's standard deviation (an unusual situation). If your data does not meet these requirements, consider using the t statistic to generate a confidence interval.

where:

M = sample mean

Z = Z statistic determined by confidence level

sM = standard error = √(s2/n)

As you can see, to perform this calculation you need to know your sample mean, the number of items in your sample, and your sample's standard deviation (or population's standard deviation if your sample size is smaller than 30). (If you need to calculate mean and standard deviation from a set of raw scores, you can do so using our descriptive statistics tools.)

Given statement solution is :-  For the third week of April, Patricia's:

Regular pay amount is $476.

Overtime pay is $231.45.

Gross pay is $707.45.

To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.

Regular Pay:

Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:

Regular Pay = Regular Hours x Hourly Rate

Regular Pay = 40 hours x $11.90/hour

Regular Pay = $476

Overtime Pay:

Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.

Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)

Overtime Pay = 13 hours x ($11.90/hour x 1.5)

Overtime Pay = 13 hours x $17.85/hour

Overtime Pay = $231.45

Gross Pay:

Gross Pay is the sum of Regular Pay and Overtime Pay.

Gross Pay = Regular Pay + Overtime Pay

Gross Pay = $476 + $231.45

Gross Pay = $707.45

Therefore, for the third week of April, Patricia's:

Regular pay amount is $476.

Overtime pay is $231.45.

Gross pay is $707.45.

Step-by-step explanation:

We have proved that the Newton-Raphson iteration formula for solving the equation\(x^k e^x = 0\) is given by \(x_{n+1} = (k - 1) x_n + x_n^2 / k + x_n.\)

To prove that the Newton-Raphson method for solving the equation \(x^k e^x = 0\), where k is a constant, is given by the formula

\(x_{n+1} = (k - 1) x_n + x_n^2 / k + x_n,\)

we can start by considering the iterative process of the Newton-Raphson method.

Given an initial guess \(x_n\), we want to find a better approximation \(x_{n+1}\)that is closer to the root of the equation \(x^k e^x = 0.\)

The Newton-Raphson method involves the following steps:

Calculate the function value \(f(x_n) = x_n^k e^x_n\) and its derivative \(f'(x_n) = k x_n^(k-1) e^x_n.\)

Find the next approximation x_{n+1} by using the formula:

\(x_{n+1} = x_n - f(x_n) / f'(x_n)\)

Let's apply these steps to our equation \(x^k e^x = 0\):

Calculate the function value and its derivative:

\(f(x_n) = x_n^k e^x_n\\f'(x_n) = k x_n^(k-1) e^x_n\)

Find the next approximation x_{n+1} using the formula:

\(x_{n+1} = x_n - f(x_n) / f'(x_n)\)

Substituting the function value and its derivative:

\(x_{n+1} = x_n - (x_n^k e^x_n) / (k x_n^(k-1) e^x_n)\\= x_n - (x_n^k / k)\)

Simplifying the expression by combining like terms:

\(x_{n+1} = x_n - (x_n^k / k)\\= x_n - x_n^k / k\\= (k - 1) x_n + x_n^2 / k + x_n\)

Therefore, we have proved that the Newton-Raphson iteration formula for solving the equation\(x^k e^x = 0\) is given by \(x_{n+1} = (k - 1) x_n + x_n^2 / k + x_n.\)

There are 16 outcomes in the sample space for pulling a marble out of the box and spinning the spinner.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To find the total number of outcomes in the sample space for pulling a marble out of the box and spinning the spinner, we need to multiply the number of outcomes for each event.

The number of outcomes for pulling a marble out of the box is 4, since there are 4 marbles in the box.

The number of outcomes for spinning the spinner is 4, since there are 4 equal sections on the spinner.

To find the total number of outcomes, we multiply the number of outcomes for each event:

Total number of outcomes = Number of outcomes for pulling a marble out of the box x Number of outcomes for spinning the spinner

Total number of outcomes = 4 x 4

Total number of outcomes = 16

Therefore, there are 16 outcomes in the sample space for pulling a marble out of the box and spinning the spinner.

Mean = average, add all numbers then divide by how many

Median = midpoint, middle number.  Be sure to list numbers from small to large if there are 2 middle numbers (this happens when there are an even amount), take the average of the 2 middle numbers

Mode = numbers that occurs the most in the list of numbers

Range = This is the largest number minus the smallest number.  

In the given graph, ABCD is the preimage and EGHF is the image. If the second step in a similarity transformation between these two figures is dilation by 1/2. So option D. (x,y)→(y,-x) is the answer.

Let us understand the steps in a similarity transformation: S1: We reflect (flip) the figure over the line y = x.

S2: We perform a dilation (stretch) from the origin.

S3: We reflect (flip) the figure over the line y = -x. Thus, when we perform a dilation by 1/2, it means we will be performing S2 first. The dilation occurs from the origin.

So, all points will be stretched to half the distance from the origin. Hence, the transformation is (x, y) → (1/2x, 1/2y).The correct option is D. (x,y)→(y,-x).

Here, we see that the figure is reflected over y = x first, and then over y = -x. Thus, we can say that the first step in this transformation is S1, (x,y)→(y,x).

Answer:

0.5 = 50% probability that 13 or more ounces will be dispensed in a given glass

Step-by-step explanation:

The uniform distribution is used when every outcome has the same probability.

It has two extremes, a and b.

If we want to find the probability of a value being higher than x, we use the following formula:

\(P(X > x) = \frac{b - x}{b - a}\)

Assuming that the amount of water dispensed follows a continuous uniform distribution from 10 ounces to 16 ounces

This means that \(a = 10, b = 16\)

What is the probability that 13 or more ounces will be dispensed in a given glass

\(P(X > 13) = \frac{16 - 13}{16 - 10} = 0.5\)

0.5 = 50% probability that 13 or more ounces will be dispensed in a given glass

Hey there!

so the first thing we want to do is find the scale factor

to do so we divide the actual length by the scale drawings length

33/11=3 so the scale factor is 3

then we divide the width by 3 to get the width of the scale drawing

now we can find the area of the scale drawing by multiplying the length and width

✓12*11=132

so the area of the scale drawing is

The distance between the tops of the buildings is 28.5 meters.

To find the distance between the top of the buildings, we can use the concept of similar triangles.

Let's denote the height of the shorter building as "a" (12 m) and the height of the taller building as "b" (19 m). The distance between the buildings can be denoted as "c" (18 m), and the distance between the top of the buildings as "x" (which we need to find).

We can set up a proportion based on the similar triangles formed by the buildings:

a/c = b/x

Substituting the known values:

12/18 = 19/x

To find "x," we can cross-multiply and solve for "x":

12x = 18 * 19

12x = 342

x = 342/12

x = 28.5 m

Therefore, the distance between the tops of the buildings is 28.5 meters.

Where ? = 2.

Step-by-step explanation:

We want to prove that the difference of the squares of two successive integers is equal to the sum of the integers.

In other words, we want to show that for any given integer n:

\(\displaystyle (n+1)^2 - n^2 = n + (n+1)\)

From the original equation, expand:

\(\displaystyle = (n^2 + 2n + 1) - n^2\)

Combine like terms:

\(= 2n +1\)

And rewrite. Hence:

\(\displaystyle = n + (n + 1)\)

Therefore:

\(\displaystyle \begin{aligned} \displaystyle (n+1)^2 - n^2 &= 2n +1 \\ &= n (n+1)\end{aligned}\)
