Answer:3 - x/4
Step-by-step explanation: quotient of x and 4 = x/4. 3 minus x/4 = 3 - x/4.
The expression representing the sentence is [tex]$3 -\frac{x}{4}[/tex].
We have a sentence - "3 minus the quotient of x and 4".
We have to determine the expression that represents the sentence.
Express the statement - "The difference of x and y is equal to an irrational number" in the form of expression.The expression representing the above statement is -
x - y = π.
According to the question, we have -
3 minus the quotient of x and 4.
Using the Division Algorithm -
x = 4q + r
Substituting r = 0 by introducing decimals in the quotient, we get -
q = [tex]$\frac{x}{4}[/tex]
Therefore -
[tex]$3 -\frac{x}{4}[/tex]
Hence, the expression representing the sentence is [tex]$3 -\frac{x}{4}[/tex].

What is the maximum value of the transformed function, y = -3cos (2x - 8) + 5
A. 3 units
B. 5 units
C. 8 units
D. 11 units
Answer:
C. 8 units.
Step-by-step explanation:
The maximum value of the cosine ( cos) function is 1
So, for y = 3cos(2x - 8) + 5
Maximum value is 3 *1 + 5 = 8.
y = -3cos(2x - 8) + 5 is the above graph reflected in the y axis so the maximum value is also 8.

Considering the given graph, we have that:
The slope of the graph of the function is equal to 1 for x between x = -3 and x = -2.The slope of the graph is equal to 0 for x between x = 3 and x = 4.The greatest value of y is y = 4.The smallest value of y is y = -3.How to find the slope of a function?The slope of a function, given two points, is given by the change in y divided by change in x.
When x = -3, y = -3, and while x = -2, y = -2, hence when x changes by 1, y also changes, hence the slope of the graph of the function is equal to 1 for x between x = -3 and x = -2.
When x = 3, y = 4, and when x = 4, y = 4, hence the slope of the graph is equal to 0 for x between x = 3 and x = 4.

factor (16x^2-8x+1)
Please show your work lol
Answer:
(4x - 1)^2.
Step-by-step explanation:
16x^2 - 8x + 1
Multiplying the first and last coefficients:
16 * 1 = 16
We need 2 numbers whose product is 16 and whose sum is -8.
These are - 4 and -4.
So we now write:
16x^2 - 4x - 4x + 1
Now factor by grouping :
= 4x(4x - 1) - 1(4x - 1)
= (4x - 1)(4x - 1)
= (4x - 1)^2
This method of factoring quadratics is called the 'ac' method - you split the middle term ( in this case the -8x) into 2 parts.
Answer:
[tex](4x-1)^2[/tex]
Step-by-step explanation:
Given quadratic expression:
[tex]16x^2-8x+1[/tex]
To factor a quadratic in the form [tex]ax^2+bx+c[/tex], find two numbers that multiply to ac and sum to b:
[tex]ac = 16 \times 1 = 16[/tex][tex]b = -8[/tex]Therefore, two numbers are: -4 and -4
Rewrite the middle term as the sum of these two numbers:
[tex]\implies 16x^2-4x-4x+1[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 4x(4x-1)-1(4x-1)[/tex]
Factor out the common term (4x - 1):
[tex]\implies (4x-1)(4x-1)[/tex]
Apply the exponent rule: aa = a²
[tex]\implies (4x-1)^2[/tex]

Answer:
y = 5x - 6
Step-by-step explanation:
We are given a line, which is parallel to the line y=5x+3.
We also know that this line passes through the point (3,9).
We want to find the equation of this line.
Parallel lines have the same slopes, yet different y intercepts.
So, let's find the slope of the line y=5x+3.
The line is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the value of y at the y intercept.
As 5 is in the place of where the slope (m) is, 5 is the slope of the line.
It is also the slope of the line parallel to it (which is the line we are trying to find).
We can write the equation of this new line in slope-intercept form as well, which is also the format your system wants.
Before we write the equation of the line in slope-intercept form, we can write it in point-slope form, then convert it into slope-intercept form.
Point-slope form is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point.
As we have already found the slope (5), we can immediately plug it into the formula.
[tex]y-y_1=5(x-x_1)[/tex]
Now, remember that we were also given a point, that passes through the line. This point is (3,9).
We can use its values in the formula.
Substitute 3 as [tex]x_1[/tex] and 9 as [tex]y_1[/tex].
y - 9 = 5(x-3)
Now, we have written the line in point-slope form.
However, we're not done yet; remember that we want it in slope-intercept form.
We can solve the equation for y to get slope-intercept form.
So, on the right, open up the parentheses and distribute 5 to both x and -3.
y - 9 = 5x - 15
Now add 9 to both sides.
y = 5x - 6

Which function in vertex form is equivalent to f(x) = 4 + x² - 2x?
O f(x) = (x - 1)² + 3
O f(x) = (x-1)² + 5
O f(x) = (x + 1)² + 3
O f(x) = (x + 1)² +5
Answer:
f(x)=(x-1)^2+3
Step-by-step explanation:
Both equations vertexes equal (1, 3) while the rest do not match.
f(x) = (x - 1)² + 3 function in vertex form is equivalent to f(x) = 4 + x² - 2x.
We can use the technique of completing the square to rewrite the given function f(x) in vertex form.
f(x) = 4 + x² - 2x
f(x) = (x² - 2x) + 4
Adding and subtracting (1) inside the parentheses
f(x) = (x² - 2x + 1) + 4 - 1
f(x) = (x - 1)² + 3
So, the equivalent function in vertex form is f(x) = (x - 1)² + 3.
Therefore, the correct option is f(x) = (x - 1)² + 3.

Izzo's Pizza sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what he found. Type of Crust Number Sold
Thin crust 307
Thick crust 224
Stuffed crust 161
Pan style 191
Based on this information, of the next 2000 pizzas he sells, how many should he expect to be stuffed crust or pan style? Round your answer to the nearest whole number. Do not round any intermediate calculations.
Answer:
797
Step-by-step explanation:
First, we need to find the number of pizzas sold last week by finding the sum of the pizzas sold:
307 + 224 + 161 + 191 = 883
Next, we need to find the proportion of stuffed crust and pan style pizzas sold last week by adding the number of both sold and dividing by the total number of pizzas sold:
(191+161) / 883 = 352 / 883
Now we need to multiply this proportion by 2000 to find the expected number of stuffed crust or pan style pizzas:
(352 / 883) * 2000 = 797.28 = 797

If amy cuddy and her research team originally established a sample size of n=200 (100 in each group) and then discovered that 86% of the high-power group (86 of 100) took a gambling risk while 60% of the low-power group (60 of 100) took the risk, then the p-value would have been much lower than that originally found in question 1. this p-value would have been less sensitive and would have provided stronger evidence for the researcher's hypothesis. state the p-value, rounding to 5 decimal places.
The p-value that would be given as the evidence would be given as p-value = 0.00002 and also P value = 0.00003
How to solve for the p valueThe sample size of the first sample = 100
x1 = success 0f 86%
We have to find the proportion of this = 0.86
The sample size of the second sample n2 = 100
x12 = success 0f 60%
We have to find the proportion of this = 60/100
= 0.6
The difference = 0.86-0.6= 0.26
Next we have to find the pooled proportion. This is taken given as p = (x1+x2)/(n1+n2) this gives us 0.73
Next we have to find the standard error
= √(p*(1-p)*(1/n1+ 1/n2)= 0.06279
Z stat = (0.26-0)/0.0628= 4.1411
From here the p value would have to be
p-value = 0.00002 and also
