Gabriella can line up her textbooks in 24 different ways on her bookshelf.
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
Given that;
Gabriella has a Spanish book, a biology book, physics book, and a health text book.
We have;
She has a total of 4 books in her book shelf.
So, the number of positions in which the books have to be put are four.
As we can see,
The books are only one in number each. So, the choices are not repeatable.
So, In first position we have four choices, in third we will be left with three choices, in the seconds position we will have a total of two books as choice and in the last positive we have to put the book that is left.
So, the total different ways in which she can line up her books in the bookshelf are,
= 4×3×2×1
= 24
Thus, There are 24 different ways possible.

This recipe makes 30 shortbread fingers.
Rose follows this recipe, but only wants to make 6 fingers.
How much of each ingredient does she need?
Recipe: Makes 30
120 g butter
60 g sugar
180 g flour
Answer:
24 g butter
12 g sugar
36 g flour
Step-by-step explanation:
The recipe makes 30 shortbread fingers.
She wants to make 6 fingers.
6/30 = 1/5
She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.
Divide each amount by 5.
Recipe:
Makes 30 30/5 = 6 Makes 6
120 g butter 120/5 = 24 24 g butter
60 g sugar 60/5 = 12 12 g sugar
180 g flour 180/5 = 36 36 g flour
If f(x)= x squared and g(x)=2x^3- x squared, find f(x)-g(x).
Answer:
[tex]f(x)-g(x)=2x^2(1-x)[/tex]
Step-by-step explanation:
Given that,
[tex]f(x)=x^2\\\\g(x)=2x^3-x^2[/tex]
We need to find the value of f(x)-g(x).
Put the values of f(x) and g(x). So,
[tex]f(x)-g(x)=x^2-(2x^3-x^2)\\\\=x^2-2x^3+x^2\\\\=2x^2-2x^3\\\\=2x^2(1-x)[/tex]
So, the value of f(x)-g(x) is equal to [tex]2x^2(1-x)[/tex].

The mean breaking strength of a ceramic insulator must be at least 10 psi. The process by which this insulator is manufactured must show equivalence to this standard. If the process can manufacture insulators with a mean breaking strength of at least 9.4 psi, it will be considered equivalent to the standard. A random sample of 50 insulators is available, and the sample mean and standard deviation of breaking strength are 9.22 psi and 0.24 psi, respectively. a. State the appropriate hypotheses that must be tested to demonstrate equivalence.
Answer:
H0 : u ≥ 10 against the claim Ha: u < 10
Step-by-step explanation:
The mean breaking strength of a ceramic insulator must be at least 10 psi.
(At least means greater or equal to ). As it is already given in the data the null and alternate hypotheses will be formulated according to it.
H0 : u ≥ 10 against the claim Ha: u < 10
The null hypothesis is the mean breaking strength of a ceramic insulator must be at least 10 psi
and the alternate hypothesis is
the mean breaking strength of a ceramic insulator is less than 10 psi

Answer:
Use PEMDAS
Step-by-step explanation:
First, solve inside the (P)arentheses. Next, calculate all (E)xponents. Then check to see which comes first in the equation: multiplication or division? Complete these in the order that they appear in the equation. Now, repeat the previous step with addition and (S)ubtraction. If all else fails, use MathPapa.

The scores on a test are normally distributed with a mean of 130 and a standard deviation of 26. What is the score that is 25 standard deviations below the mean?
Answer: The z-score for an ACT score of 26 is 0.17.
Step-by-step explanation:
Z-score:
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.
This means that
Find the z-score for an ACT score of 26.
This is Z when X = 26. So
The z-score for an ACT score of 26 is 0.17.
The z-score for an ACT score of 26 is 0.17.
What is z-score?
When assessed in terms of standard deviation units, a raw score's location in relation to its distance from the mean is indicated by a z-score. If a value is above the mean, the z-score is positive; if it is below the mean, it is negative.
In a set with mean and standard deviation , the z-score of a measure X is given by: z-score=(x-μ)/σ
How do you find z-score?
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.
This means that
We need to find z-score for an ACT score of 26.
This is Z when X = 26. So
The z-score for an ACT score of 26 is 0.17

b) The diagram shows a straight line L.
i) Find the equation of line L.
Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2-x_{1} } }[/tex]
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = [tex]\frac{0-6}{3-0}[/tex] = [tex]\frac{-6}{3}[/tex] = - 2
The line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - 2x + 6 ← equation of line

an)?
A) (5, 75), (6,86)
B) (5, 81), (6,100)
C)(5, 125), (6, 216)
D) (125, 5), (216, 6)
Answer:
C)(5, 125), (6, 216)
Step-by-step explanation:
Well firstly, there's no actual way to know. There could be anything there, as for any n pairs (x, y) with distinct x-s, there exists a (n-1 or less)-degree polynomial that models them perfectly, and infinitely many polynomials of degree n (or more).
If we input those terms to a polynomial interpolator, we'll get an answer every time.
With this one, it will be the right answer though!
But to be serious, let's find out what the numbers are. We can notice they're all cubic numbers.
There's 1, which is 1^3, then theres 2^3, then it's 3^3, then 4^3.
It's reasonable to expect that we are expected to assume (x, x^3) is the rule.
We can see that the answer C (5, 5^3), (6, 6^3) fits this narrative.
MATH QUESTION PLEASE HELPPP ASAP, DUE IN AN HOUR
Answer:
Perimeter = [tex](30-\frac{3}{2}x)[/tex]
Step-by-step explanation:
Width of the rectangle has been given as [tex](5-\frac{1}{4}x)[/tex].
Convert the statement into the algebraic expression,
"Length of the rectangle is twice the width"
Length = 2(Width)
= [tex]2(5-\frac{1}{4}x)[/tex]
= [tex]10-\frac{1}{2}x[/tex]
Since perimeter of a rectangle is given by the expression,
Perimeter = 2(Length + Width)
By substituting the values of length and width in the expression,
Perimeter = [tex]2[(5-\frac{1}{4}x)+(10-\frac{1}{2}x)][/tex]
= [tex]2(15-\frac{3}{4}x)[/tex]
= [tex](30-\frac{3}{2}x)[/tex]
Therefore, expression representing perimeter is [tex](30-\frac{3}{2}x)[/tex].
