18=0.125 . Which calculation is NOT a way to find 58?
The calculation that is not a way to find a fraction of 5/8 is:
1 - 0.125.
What is a fraction?A fraction is a numerical representation of the division of the two terms x and y, as follows:
Fraction = x/y.
The terms are classified as follows:
The top term x is the numerator of the fraction.The bottom term y is the denominator of the fraction.Hence the numeric value of the fraction 5/8 presented in this problem is given as follows:
5/8 = 0.625.
The calculation that is not a way to find the fraction of 5/8 is the only expression that has a different value than 5/8.
The expression with a different value is of:
1 - 0.125 = 0.875.
As the value of 0.875 is different than the value of 0.625 equivalent to the fraction of 5/8.

a square with side length 2 and a circle share the same center. the total area of the regions that are inside the circle and outside the square is equal to the total area of the regions that are outside the circle and inside the square. what is the radius of the circle?
The radius of the circle which is overlapping the square is 1.12.
The length of side of the square is 2. Let us say that the radius of the circle is R.
The circle and the square are overlapping on each other.
The area of the region that are outside the circle but inside the square are equal to the area of the region which are inside the circle but outside the square.
Let us name the area of the region that are outside the circle but inside the square as M.
Let us name the area of the region which are inside the circle but outside the square as N.
Let us say that the area that is common in both is C.
The area of the square is 4.
So, according to the question,
M + C = 4
And,
N + C = πR²
And we know, M = N,
So,
C - πR² = C - 4
R = 2/√π
R = 1.12.
So, the radius of the circle is 1.12

there are four boxes that look the same. in one box (the special box), half of the marbles are blue. but only 1/8 of the marbles in the other boxes are blue. you pick a box at random and randomly select a marble from it. the marble is blue. what should your new odds be that the box you picked is the special one?
The new odds that the box picked is a special one is 4
Since, there are four boxes that look the same. in one box (the special one), half of the marbles are blue. but only 1/8 of the marbles in the other boxes are blue.
We will have this hypothesis:
The box the blue marble was picked from is the special box.
Prior confidence we had:
Ratio of special boxes to non special boxes=1:3
Now P(blue &special)=1/2, given that a box is selected from the special box, there is 1/2 chance that it is blue
And P(blue & not special)=1/8, given that a box is selected from a non-special box, there is 1/8 chance that it is blue
According to Baye's factor ,we get:
P(B & S)/P(B & NS)=(1/2)/(1/8)
=4
Thus, 4 is the new odds that the box picked is the special one.

There are 24,024 different ways to choose a President, Vice President, Treasurer, and Secretary from a group of 14 students.
Permutation is the arrangement of objects in a specific order. It is the number of different ways in which a set of objects can be arranged in a specific order. The formula to calculate permutation is:
[tex]P(n, r) = n! / (n - r)![/tex]
Permutations are commonly used in mathematics, science, and engineering, and are useful for solving problems that involve counting the number of possible arrangements of objects or events.
We can use the formula for permutations to find the number of ways to choose the four officers from a group of 14 students.
The number of permutations of n objects taken r at a time is given by:
[tex]^nP_r = n! / (n - r)![/tex]
where n! denotes n factorial, which is the product of all positive integers up to n. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
In this case, we want to choose 4 students from a group of 14, and the order in which they are chosen matters (since we are electing them to specific positions). So we have:
n = 14
r = 4
The number of ways to choose the four officers is therefore:
[tex]^1^4P_4 = 14! / (14 - 4)! = 14 \times 13 \times 12 \times 11 = 24,024[/tex]
Therefore, there are 24,024 different ways to choose a President, Vice President, Treasurer, and Secretary from a group of 14 students.

The tables represent two linear functions in a system. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 26, 18, 10, 2. A 2 column table with 5 rows. The first column, x, has the entries, negative 4, negative 2, 0, 2. The second column, y, has the entries, 14, 8, 2, negative 4. What is the solution to this system? (1, 0) (1, 6) (8, 26) (8, –22) Mark this and return
From the given table which represents the two system of linear function is given by y = -4x +10 and y = -3x +2 , the solution of the system of linear function is (x, y) = (8 , -22).
As given in the question,
Table which represents the system of linear function are as follow:
table 1:
x: -4 -2 0 2
y: 26 18 10 2
table 2:
x: -4 -2 0 2
y: 14 8 2 -4
For table1 :
System of linear function:
(x₁ , y₁) = (0,10)
(x₂ , y₂) = (2, 2)
Equation of linear function:
(y -y₁)/ (x-x₁) =(y₂ -y₁)/(x₂ -x₁)
⇒(y -10)/ (x-0) =(2-10)/(2-0)
⇒y-10 =-4(x)
⇒ y = -4x +10 __(1)
For table2 :
System of linear function:
(x₁ , y₁) = (0,2)
(x₂ , y₂) = (2, -4)
Equation of linear function:
(y -y₁)/ (x-x₁) =(y₂ -y₁)/(x₂ -x₁)
⇒(y -2)/ (x-0) =(-4-2)/(2-0)
⇒y-2 =-3(x)
⇒ y = -3x +2 __(2)
Solve system of linear function (1) and (2) we get,
-4x +10 = -3x +2
⇒4x -3x =10 -2
⇒x =8
⇒y = -4(8) +10
= -22
(x, y) = (8 ,-22)
Therefore, from the given table which represents the two system of linear function is given by y = -4x +10 and y = -3x +2 , the solution of the system of linear function is (x, y) = (8 , -22).

The equation p=5xy+q can be expressed in terms of p,q, and x as y = (p-q)/5x.
The equation p=7x+4q can be expressed in terms of p and q as x = (p-4q)/7x.
Given in the first equation, p = 5xy+q
p-q=5xy
y=(p-q)/5x
Here we need to express y in terms of p,q, and x so we need all these three variables on one side of the equation and y on the other side. Initially we more q to the left-hand side of the equation which makes it p-q=5xy. Now we divide the left-hand side and the right-hand side by 5x making the equation y = (p-q)/5x.
Similarly in the second equation, p = 7x+4q
p-4q = 7x
x = (p-4q)/7
Here we need to express x in terms of p and q so we need all these two variables on one side of the equation and the term x on the other side. First, we will move 4q to the left-hand side of the equation which will make it p-4q=7x. Now, we will divide the whole equation by 7 which will make the equation x = (p-4q) / 7.

Simplifying the left side, we get:

Next, we divide both sides by -2. Since we are dividing by a negative number, we need to flip the inequality sign:
