To factor the expression x³ - y³ into factors of the lowest possible order, we can use the formula for factoring a difference of cubes: a³ - b³ = (a - b)(a² + ab + b²). In this case, we have x³ - y³, so our factors are (x - y)(x² + xy + y²). These are the factors using complex coefficients.

Kelly's estimated monthly payroll tax is $475.94, which is found by adding together all of her weekly taxes and then multiplying by the average number of weeks in a month.

To estimate the amount of payroll tax Kelly pays each month, we first need to find out how much she pays weekly and then multiply it by the number of weeks in a month on average.

Firstly, we add together all of the weekly taxes she pays, which includes federal income tax ($68.45), state income tax ($22.81), and other taxes ($18.75). The sum equals $110.01.

Then, to convert this weekly tax to a monthly estimation, we multiply by an average of 4.33 weeks in a month (since not every month is precisely 4 weeks). Therefore, $110.01 * 4.33 is approximately $475.94.

Therefore, the best estimation for the monthly payroll tax that Kelly pays is $475.94.

Answer:

[tex]13.19\ m[/tex]

Step-by-step explanation:

step 1

Divide the total height by the number of step leading

[tex]\frac{24}{91}=0.2637\frac{m}{step}[/tex]

step 2

Multiply [tex]0.2637\frac{m}{step}[/tex] by 50 step

[tex]0.2637(50)=13.19\ m[/tex]

If you were standing on the 50th step of the pyramid, you would be approximately 13.185 meters above the ground, calculated by finding the height per step and multiplying by the number of steps climbed.

The task is to calculate how high above the ground you would be if you were standing on the 50th step of a pyramid that has a temple approximately 24 meters above the ground with a total of 91 steps leading up to the temple. To solve this, we will assume that the height the steps cover (24 meters) is evenly distributed across the number of steps (91). So, each step represents 24 meters divided by 91 steps in height.

First, let's calculate the height of each step:

Height per step = Total height / Number of steps

Height per step = 24 meters / 91 steps ≈ 0.2637 meters per step

Next, we need to calculate the height at the 50th step:

Height at 50th step = Height per step * Number of steps climbed

Height at 50th step = 0.2637 meters per step * 50 steps ≈ 13.185 meters

Therefore, if you were standing on the 50th step, you would be approximately 13.185 meters above the ground.

To predict the number of defective products out of 3000, Ronen can use proportions. He found 6 defects in a sample of 75 products, which scales up to approximately 240 defects in 3000 products.

Ronen found that 6 out of 75 products had defects in a random sample. To predict how many out of 3000 products would have defects, we can set up a proportion because we are assuming that the sample proportion will be representative of the larger population. Here's the step-by-step explanation:

This calculates to 240. Therefore, Ronen can predict that approximately 240 out of 3000 products will have defects.

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the slope m = -4 and the point M(-2, 1).

The equation of a line:

[tex]y=-4x+b[/tex]

Put the coordinates of the point M to the equation of a line:

[tex]1=-4(-2)+b[/tex]

[tex]1=8+b[/tex]      subtract 8 from both sides

on edge it's C. If Terrence samples 800 more people, his margin of error will be the same as Deena’s.

Answer:

Step-by-step explanation:

Margin of error is calculated as

Critical value multiplied by Std error of sample

= Critical value multiplied by square root of (variance/sample size)

Hence Margin of error

=[tex]z/t*(\frac{\sigma}{\sqrt{n} } )[/tex]

Thus square root of n is inversely proportion to margin of error.

Thus we have margin of error of Terrena would be square root of 3 times that of Deena

Thus option a, b and d are wrong

C is right because when sample sizes equal, the margin of error also would be equal.

Answer:

[tex]P(x<4)=0.0994[/tex]

Step-by-step explanation:

If we call x the number of correct questions obtained in the 9 attempts, then:

x is a discrete random variable that can be modeled by a binomial probability distribution p, with n = 9 trials.

So, the p of x successes has the following formula.

[tex]P(x) =\frac{n!}{x!(n-x)!}*p^x(1-p)^{n-x}[/tex]

Where:

n = 9

p = 0.6

We are looking for P(x<4)

By definition:

[tex]P(x<4) = P(x\leq3) = P(0) + P(1) + P(2) +P(3)[/tex]

Then:

[tex]P(x\leq3)=\sum_{x=0}^{3} \frac{9!}{x!(9-x)!}*(0.6)^x(1-0.6)^{9-x}[/tex]

[tex]P(x\leq3)=0.0994[/tex]

Probabilities are used to determine the chances of an event

The probability that the number of correct answers is fewer than 4 is 0.0994

The given parameters are:

[tex]n = 9[/tex]

[tex]p =0.6[/tex]

The probability is a binomial probability, and it is calculated using:

[tex]P(x) = ^nC_x p^x (1 - p)^{n -x}[/tex]

Fewer than 4 means: x = 0, 1, 2 and 3

So, we have:

[tex]P(x<4) = ^9C_0 \times 0.6^0 \times (1 - 0.6)^{9 -0} +^9C_1 \times 0.6^1 \times(1 - 0.6)^{9 -1} +^9C_2 \times 0.6^2\times (1 - 0.6)^{9 -2} +^9C_3 \times 0.6^3\times (1 - 0.6)^{9 -3}[/tex]

This gives

[tex]P(x<4) = 1 \times 0.6^0 \times (1 - 0.6)^9 + 9 \times 0.6^1 \times(1 - 0.6)^8 +36 \times 0.6^2 \times (1 - 0.6)^7 +84 \times 0.6^3 \times (1 - 0.6)^6[/tex]

Using a calculator,

[tex]P(x<4) = 0.099352576[/tex]

Approximate

[tex]P(x<4) = 0.0994[/tex]

Hence, the probability that the number of correct answers is fewer than 4 is 0.0994

The total amount of sandwiches on the tray is 4+7+6. This makes 17. This will be the denominator of our fraction which we are going to use for the probability.

There are 7 ham sandwiches on the tray, therefore the probability that he will pick a ham sandwich is 7/17.

Brainliest? :)

Final answer:

The probability that Danny picked a ham sandwich is 7/17, since there are 7 ham sandwiches out of a total of 17 sandwiches on the tray.

Explanation:

The question is about calculating the probability that Danny picked a ham sandwich. To determine this, we count the total number of sandwiches and then count the number of ham sandwiches.

Total number of sandwiches = 4 turkey + 7 ham + 6 tuna = 17 sandwiches.

Since there are 7 ham sandwiches, the probability (P) that Danny picks a ham sandwich is calculated by dividing the number of ham sandwiches by the total number of sandwiches.
P(ham sandwich) = Number of ham sandwiches / Total number of sandwiches
P(ham sandwich) = 7 / 17

Therefore, the probability that Danny picked a ham sandwich is 7/17.

Answer:

4

Step-by-step explanation:

Since the value of the total prism is 28, and you know that there are two sides which are 2 from 2x1. Then you can subtract 4 from 28. You would have 4 sides left, 2 of which are px1 and the other 2 are 2xp. The total results would be 2p+4p which is 6p=24.

I hope this helps you out

Have a great Morning

FaithRawlins14

Final answer:

The term 'circle' does not represent a 3D object with volume. For calculating volume, one must consider 3D shapes like cylinders or spheres which do have volume; their volumes are calculated using the formulas V = πr²h for cylinders, and V = 4/3 πr³ for spheres, respectively.

Explanation:

It seems there is a confusion in the question as a 'circle' is a 2D shape and does not have volume. However, if we are referring to a cylinder which has a circular base, then the volume can be calculated. To find the volume of a cylinder, we use the formula V = πr²h, where V represents volume, π is approximately 3.142, r is the radius of the circular base, and h is the height of the cylinder.

In the case of a sphere, a 3D object that could be mistaken as a 'circle' in conversations, the volume formula is given by V = 4/3 π r³. This is derived from geometric principles, ensuring the units match, and considering the sphere's volume in relation to a cube that would contain it. Applying this to an example, the volume of a sphere with a radius of 4.30 inches can be converted to cubic centimeters, and would be calculated using the volume formula for a sphere.
