Answer:
Rational
Step-by-step explanation:
We first have to define what these numbers mean:
Real numbers are all the numbers on the number line, they are not imaginary numbers that cannot be quantified on the number line.
Rational numbers are numbers that have either terminating decimals or recurring decimal, for example 5.3 (terminating decimal) or 1.333...(recurring decimal). I did not use the traditional definition of "a/b where a and b are integers and b ≠ 0" because it poses some problems. For instance 22/7 fulfills this condition but it is not a rational number! So it is best defined the way I just defined it.
An irrational number is a number that does not have terminating and recurring decimal, like 3.565215805.....
Integers are real numbers that are whole numbers.
Looking at the situation, which is the money in a bank account. The value will be a number that is rational because it is always an exact amount and this implies that it will always be a terminating decimal. Note that 45.00 is also a terminating decimal.
which two values of x are roots of the polynomial below 4x^2-6x+1
Step-by-step explanation:
Just apply the quadratic formula [tex]x=\frac{-b \left \ {{+} \atop {-}} \right. \sqrt{b^{2}-4ac} }{2a}[/tex] Your equation is [tex]4x^2-6x+1[/tex] Every quadratic equation follows the general form [tex]ax^2+bx+c[/tex] In this case [tex]a=4,b=-6,c=1[/tex] Substitute into the quadratic formula:[tex]x=\frac{-(-6) \left \ {{+} \atop {-}} \right. \sqrt{(-6)^{2}-4(4)(1)} }{2(4)}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{36-16} }{8}\\x=\frac{6 \left \ {{+} \atop {-}} \right. \sqrt{20} }{8}[/tex] Now take note that the square root of any number gives a (+) and (-) result, so two different answers[tex]x=\frac{6 + \sqrt{20} }{8} ,and\\x=\frac{6 - \sqrt{20} }{8}[/tex] are the answersclick on the photo , please help

Jason is throwing a pizza party.He has 4/18 pounds of cheese available and he needs 3/8 pounds of cheese to make a pizza. How many pizzas can he make?
Step-by-step explanation:
It is given that,
Jason has 4/18 pounds of cheese available and he needs 3/8 pounds of cheese to make a pizza.
Let he can make x pizzas. It can be calculated by dividing 4/18 by 3/8 such that,
[tex]x=\dfrac{4/18}{3/8}\\\\=\dfrac{4}{18}\times \dfrac{8}{3}\\\\=0.592[/tex]
or
x = 0.6
So, he can make 0.6 part of the pizza.

A random sample of online makeup tutorial videos and sales of makeup was measured, and the computer output for regression was obtained:
Coefficients Standard Error t Stat P-value
Intercept −7.567857143 0.426240686 −17.7549 1.04E-05
Makeup Tutorial Videos 0.917857143 0.028166777 32.58652 5.11E-07
R-sq. = 99.53% R-sq. (adj) = 99.44%
Part A: Use the computer output to determine the LSRL. Identify all the variables used in the equation. (3 points)
Part B: What proportion of the variation in makeup sales is explained by its linear relationship to makeup tutorial videos? Explain. (4 points)
Part C: Determine if increased makeup sales were caused by online makeup tutorial videos. Explain your reasoning. (3 points)
Answer:
Explained below.
Step-by-step explanation:
A.
The least square regression line is:
[tex]\hat y=-7.567857143+0.917857143\cdot x\\\\\approx \\\\\hat y=-7.568+0.918\cdot x[/tex]
Here,
y = estimated sales of makeup
x = number of online makeup tutorial videos
a = -7.568 = intercept
b = 0.918 = slope of the regression line
B.
The coefficient of determination R² specifies the percentage of the variance in the dependent-variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).
So, the proportion of the variation in makeup sales that can be explained by its linear relationship to makeup tutorial videos is 99.53%.
C.
Consider the LSRL.
The slope of the regression line is positive, i.e. there is a positive relationship between the makeup sales and the online makeup tutorial videos.
So, with one unit increase in the online makeup tutorial videos the makeup sales goes up by 0.918 units.
Thus, it can be said that the increased makeup sales were caused by online makeup tutorial videos.

The area of a rectangle when the width and the length are enlarged by
1 : 2 the area c. became twice as large
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
We know the area of a rectangle is (length×width).
So, The area of a rectangle with a width of 4 in and length of 7 inch is (4×7) = 28 sq in.
Now, Its width and length are enlarged in the ratio 1 : 2.
∴ The new width is (2×4) = 8 and the new length is (1×7) and it's area is (8×7)
56 sq inches became twice as large.

Using f(x) =x^2/3-2, determine if each statement below is true or false. Show the work that justifies your answer. The statements are A. F(6)=f(-6) B. F(6)=2 • f(3)
Answer:
[tex]f(6) = f(-6)[/tex] --- True
[tex]f(6)=2 * f(3)[/tex] --- False
Step-by-step explanation:
Given
[tex]f(x) = \frac{x^2}{3} - 2[/tex]
Solving (a): f(6) = f(-6)
First, we solve for f(6) by substituting 6 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(6) = \frac{6^2}{3} - 2[/tex]
[tex]f(6) = \frac{36}{3} - 2[/tex]
[tex]f(6) = 12 - 2[/tex]
[tex]f(6) = 10[/tex]
Next, we solve for f(-6) by substituting -6 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(-6) = \frac{-6^2}{3} - 2[/tex]
[tex]f(-6) = \frac{36}{3} - 2[/tex]
[tex]f(-6) = 12 - 2[/tex]
[tex]f(-6) = 10[/tex]
We have that:
[tex]f(6) = f(-6) = 10[/tex]
Hence, the statement is true
Solving (b): [tex]f(6)=2 * f(3)[/tex]
We have that:
[tex]f(6) = 10[/tex]
Next, we solve for f(3) by substituting 3 for x in [tex]f(x) = \frac{x^2}{3} - 2[/tex]
[tex]f(3) = \frac{3^2}{3} - 2[/tex]
[tex]f(3) = \frac{9}{3} - 2[/tex]
[tex]f(3) = 3 - 2[/tex]
[tex]f(3) = 1[/tex]
[tex]2 * f(3) = 2 * 1[/tex]
[tex]2 * f(3) = 2[/tex]
So:
[tex]f(6)=2 * f(3)[/tex]
[tex]10 \neq 2[/tex]
Hence, the statement is false

A screen printer can pack up to 24 sweatshirts into a box for shipping.
In which inequality does n represent the minimum number of boxes needed to ship 360 sweatshirts to a customer?
Answer: 15
Step-by-step explanation:
360 is the amount of sweats you need to ship to a costumer. One box has 24 shirts. This gives you the equation: 360 ÷ 24 = 15.
N is 15
The inequality is 24n ≥ 360.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
A screen printer can pack up to 24 sweatshirts into a box for shipping.
Sweatshirts needed to be packed = 360.
let n represent the minimum number of boxes needed.
Then, the inequality is 24n ≥ 360.
