For the sample of weight of corn chips dispensed in dispensing machine, probability that the sample mean weight of these 100 bags falls between 10.50 and 10.80 ounces is equals to 0.4332.
We have a sample of weight of corn chips dispensed by the dispensing machine.
Dispensed weight of bag by the dispensing machine = 10 ounces
The sample of weight of bags follows the normal distribution with, sample mean, [tex] \bar x[/tex] = 10.5 ounces
standard deviations = 2 ounces
Randomly selected from this dispensing machine. Sample size, n = 100
We have to determine probability that the sample mean weight of these 100 bags falls between 10.50 and 10.80 ounces,
[tex]P( 10.50 < \bar x < 10.80),[/tex]
Using Z-score formula for sample mean in normal distribution, [tex]Z = \frac{ \bar x - \mu}{ \frac{\sigma}{\sqrt{n}} }[/tex]
where μ--> population mean
σ -->standard deviations
n --> Sample size
Now, the required probability is [tex]P( 10.50 < \bar x < 10.80)[/tex]
= [tex]P(\frac{ 10.50 - \mu }{\frac{\sigma}{\sqrt{n}}} < \frac{ \bar x - \mu}{ \frac{\sigma}{\sqrt{n}} } < \frac{ 10.80 - \mu }{\frac{\sigma}{\sqrt{n}}} )[/tex]
= [tex]P(\frac{ 10.50 - 10 }{\frac{2}{\sqrt{100}}} < z< \frac{ 10.80 - 10 }{\frac{2}{\sqrt{100}}} )[/tex]
= [tex]P(\frac{ 0.50 }{\frac{2}{10} }< z< \frac{ 0.80 }{\frac{2}{10}})[/tex]
= [tex]P(2.5 < z< 4)[/tex]
= 0.4332
Hence, required value is 0.4332.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 5, 2,4/5,... Find the 10th term.
The 10th term round to the nearest thousandth of the geometric progression is found as 0.001.
Explain the term geometric progression?A sort of sequence known as geometric progression (GP) is one in which each following phrase is created by multiplying every preceding word by a fixed number, or "common ratio." This progression is sometimes considered to as a pattern-following geometric sequence of numbers.For the stated sequence:
5, 2,4/5,...
Check for AP:
a₂ - a₁ = 5 - 2 = 3
a₃ - a₂ = 4/5 - 2 = -6/10 = -3/10
As the common difference is not same, it is not an AP.
Check for GP:
a₁ = 5
a₂ = a₁ q²⁻¹
a₂ = 5q = 2
a₃ = a₁q³⁻¹
= a₁q²
a₃ = 5q² = 4/5
As,
a₂/ a₁ = 2/5
a₃/a₂ = 2/5, it is an GP
Thus,
a₁₀ = a₁qⁿ⁻¹
= 5*(2/5)⁹
= 0.001
Thus, the 10th term round to the nearest thousandth of the geometric progression is found as 0.001.

How do you dilate a triangle with center points?
To dilate a triangle with center points we multiply the coordinates of the points in the preimage by the scale factor to determine the points in the image.
What is a scale factor?
A scale factor is a numerical value that is used to represent an object's larger or shrunk shape. It is a number that can be used to alter the size of any geometric figure or shape in relation to its initial size. It aids in altering the figure's size but not its shape.
Here,
we have to determine how we dilate a triangle with center points.

When raising a complex number to a power, we can use the property [tex](a + bi)^n = a^n + (na^{(n-1)})bi + (n(n-1)/2!)a^{(n-2)(bi)^2} + .... + (n(n-1)...21)(a*bi)^n[/tex]
It is also possible to simplify the powers of complex numbers using De Moivre's Theorem:
[tex](a + bi)^n = a^n + (na^{(n-1)})bi + (n(n-1)/2!)a^{(n-2)(bi)^2} + .... + (n(n-1)...21)(a*bi)^n[/tex]
Where [tex](a + bi)^n = r^n * (cos(n\theta) + i*sin(n\theta))[/tex]
Where r is the magnitude, θ is the argument, and n is an integer.
For example, if we raise i to the power of 3, we can use De Moivre's Theorem:
i³ = (cos(90) + isin(90))³ = cos(270) + isin(270) = -i
So, i³ = -i
When raising complex numbers to powers, the magnitude will be raised to the power of n while the argument will be multiplied by n.

From the provided value of the paid price of the car and sales tax percentages, The answer is $564.
What do you mean by percentages?Percentages are a way to express a number as a part of 100. The symbol for percentage is %. For example, 25% means 25 out of 100, or one quarter. To convert a percentage to a decimal, divide it by 100. For example, 25% = 25/100 = 0.25. To convert a decimal to a percentage, multiply it by 100. For example, 0.25 = 0.25 * 100 = 25%. You can also calculate percentage by multiplying the number with the percentage rate. For example, if you want to find out what 25% of 50 is, you can calculate it by multiplying 50 by 0.25 (since 25% is the same as 0.25 as a decimal).

A car moving at a contant peed paed a timing device at t0. After econd, the car ha traveled ft. Write a linear function rule to model the ditance in feet d the car ha traveled any number of econd t after paing the timing device
The required equation is:
1. d = 81t
2. f(t) = 81t
Now, According to the question:
Given that a car moving at a constant speed passed a timing device at t=0.
In other words, at t = 0 second, d = 0 ft.
We know that
distance = rate × t
After 7 seconds, the car has traveled 567 ft.
In other words, at t = 7 seconds, d = 567 ft
Thus, there are two points
(0, 0)
(7, 567)
Finding the slope between (0, 0) and (7, 567)
Using the formula
Slope = Rate of change = [y₂-y₁] / [x₂-x₁]
= [567 - 0] / [7-0]
= 567 / 7
= 81 ft./second
Given that the car is moving at constant speed. So, we don't have any other factor or term to consider
Thus, the required equation is:
distance = rate × t
d = 81 × t
d = 81t
or
f(t) = 81t
VERIFICATION
Given the equation
d = 81 × t
Put t = 0 to find the distance in 1 sec
d = 81 × (0) = 0 ft.
Put t = 7 to find the distance in 7 seconds
d = 81 × (7) = 567 ft.

The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, the opposite of z is greater than 5.
So, we have the following absolute value inequality.
|z|>5
This can be written as z>5 or z<-5
5 is a positive number.
So, we make use of the inequality z<-5.
From the above inequality, the possible values of z are -6 and -7
Note that there are other values of z
The values that z cannot be
We have: z>5 or z<-5
The values that z cannot be, are represented with the inequality z>5.
From the above inequality, z cannot be 6 and 7

The graph of the player two's function g(t)=16(t-5)²+290 is given in the attachment. The baseball's maximum height is 290 ft. At 5 seconds the baseball was at its maximum height. After 9.25 second the baseball hit the ground.
What is function?A function is a mathematical device that converts one value to another in a predictable manner. We can think of it as a machine. You give the machine an input, it performs some calculations on it, and then returns another value - the result of the calculations.
The function's name is f. We can call it anything we want, but single letters are common. The input* value is referred to as x. Again, we could use anything, but x is common. What the function does with the input is shown to the right of the equals sign.
In this case, the function takes the input x, multiplies it by three, and returns the result.

There is no function in the first set of ordered pairs. It is not a function because the X value of 7 repeats.
what is function ?The subject of mathematics includes quantities and their variations, equations and related structures, forms and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A relationship between inputs and outputs in which each input leads to a single, distinct result is known as a function. Each function is given a domain and a codomain, or scope. Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, within functions, and on functions.
given
Only the first set of ordered pairs is a function; the second, third, and fourth do not represent functions.
This is due to the need that each x value have a unique y value. So you note that, with the exception of the first set of ordered pairs, all sets of ordered pairs have two distinct x-values that share a same y-value, which is not possible.
