Step-by-step explanation:

By the conjugate root theorem, since the coefficients are real, the complex conjugate of a root must also be a root.

The mean of Class 1 is 78.83.

The median of Class 1 is  88

The mode of Class 1 is 90

The mean of Class 2 is 79.42

The median of Class 2 is 85.50

The mode of Class 2 is 90

The mean of Class 3 is 79.42

The median of Class 3 is 78

The mode of Class 3 are 75 and 80

The standard deviation of Class 1 is 18.81

The standard deviation of Class 2 is 16.15

The standard deviation of Class 3 is 12.70.

The class that had the higher standard deviation is class 1.

The class that did better on the exam is class 3 because it has the higher mean and the lowest standard deviation.

Mean is the average of a set of numbers.

Mean = sum of numbers / total number

Mean of Class 1 = (45 + 50 + 55 + 68 + 77 + 86 + 90 + 90 + 90 + 95 + 100 + 100) / 12 = 78.83

Mean of Class 2 = (40 + 64 + 65 + 70 + 80 + 84 + 87 + 88 + 90 + 90 + 95 + 100) / 12 = 79.42

Mean of Class 3 = (55 + 65 + 70 + 75 + 75 + 76 + 80 + 80 + 88 + 90 + 99 + 100) / 12 = 79.42

Median is the number that is at the center of the dataset that is arranged in either ascending or descending order.

Median of Class 1 = (86 + 90) / 2 = 88

Median of Class 2 =  (84 + 87) / 2 = 85.50

Median of Class 3 = (76 + 80) / 2 = 78

Mode is the number that occurs most frequently in a dataset.

Standard deviation is used to calculate the average variation of a dataset.

Standard deviation = [tex]\sqrt{\frac{(x - u)^{2} }{n} }[/tex]

Standard deviation of Class 1 = 18.81

Standard deviation of Class 2 = 16.15

Given the equation 13.25y = 79.5, the value of y is A. 6.00.

An equation is a mathematical statement that states that two mathematical expressions are equal in value.

Equivalent values are also expressed as algebraic equations sharing the same root.

We depict equations by using the equation symbol (=).

13.25y = 79.5

y = 6 (79.5/13.25)

Check:

13.25y = 79.5

13.25(6) = 79.5

79.5 = 79.5

Thus, given the equation 13.25y = 79.5, the value of y cannot be 66.25, 92.75, or 1,053.38 but Option A.

The expression when a = 2 and x = -4, given 2a-x. The value will be 8.

In mathematics, an operation is a function that transforms zero or more arguments or operands into a clearly defined output value. The number of operands in the operation determines how difficult it is.

Unary operations (i.e., operations of arity 1), which include additive inverse and multiplicative inverse, as well as binary operations (i.e., operations of arity 2), which include addition and multiplication, are the operations that are most frequently studied. The nullary operation, also referred to as a zero-arity operation, is a constant. The mixed product is an example of a ternary operation, also referred to as an operation of arity 3.

The arity is typically assumed to be limited. Even yet, infinitary operations are occasionally taken into account, in which case the "typical" operations of finite dimensionality are referred to as finiteary operations.

Similar to an operation, but with partial function in place of a function, is the definition of a partial operation.

Since, a= 2 and x= -4, then,

2(2)-(-4)= 8

Step-by-step explanation: Reciprocals are just the fraction flipped

From the given figure < BAC = 180 - ( < ABC + < BCA ) because they are sum of angles in a triangle

given data

< ABC = 52 degrees

< BCA = 88 degrees

calculation for angle BAC

< ABC + < BCA + < BAC = 180 degrees ( sum of angles in a triangle )

< BAC = 180 - ( < ABC + < BCA )

< BAC = 180 - < ABC - < BCA

Answer:

x = -9

Step-by-step explanation:

the goal is to get x by itself, so subtract 10 from both sides: 4x=-36

divide both sides by 4: x = -9

|-----4x+10=-26           |

|ANSWER= x=-9-------|

happy fall!

explanation ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When we have questions like this, and the x is just THROWN in there, we have to "combine our like terms."

STEP ONE ✨: "How do we do that..if one is on the other side?"

We have to make it disappear. +10-10 equals zero, right? right! So do that!

4x+10=-26

   -10

But what we do to one side, we do to the other! Subtract 10 from the numbers on the equal side.

4x+10=-26

    -10  -10

-26-10

4x=-36

STEP TWO : What do we do when a number has an X beside it?
Since this number is being multiplied to the x, we have to DIVIDE the 4x by 4, so we just get the x alone. It always works like this. Don't doubt yourself!!

4x=-36

/4    /4

-36/4=-9
x=-9!

The theorem can be used to readily show the corollary because, according to its statement, it considerably depends on it. Consequently, the assertion is accurate.

The given statement is True.

The term "corollary" refers to an outcome that follows logically from another action. You could claim that your rediscovered passion of reading is a corollary to the recent opening of a bookstore in your area. The term corollary describes the result of an action, such as the need to study more as a corollary to receiving a poor grade.

A theorem states that two angles that add up to 180° and form a straight line are regarded as "supplementary."

A corollary of this is known as the "Vertical Angle Theorem," which asserts that where two lines intersect, their angles across from each other are equal (in the diagram, a=c and b=d).

Using the properties of an arithmetic sequence we can conclude that the total number of match boxes is 66.

There is a consistent distinction between the words in a sequence of numbers known as a "arithmetic progression" or "arithmetic sequence" (AP).

We know that the bottom row of the pyramid has 11 matchboxes .

As we can see in the figure that the each succeeding step has one matchbox less.

Therefore the number of matchboxes in each row is in an AP.

Therefore the AP has a common difference of  -1 and the first term is 11

The last term of the AP is 1.

Therefore

aₙ = a + (n-1)d

or, 1 = 11 + (n-1)(-1)

or, n = 11

We know that the sum of all terms of an AP is given by

S=n/2{2a+(n-1)d}

or, S = 11/2 {2×11 + (10)(-1)}

or, S = 66

Therefore from the arithmetic progression we calculate that the total number of match boxes is 66.

Number of balls of clay: 10

Step-by-step explanation:

The volume of the cube is  [tex]$V_{\text{cube}}=7^3=343,$[/tex]

and the volume of a clay ball is: [tex]$V_{\text{ball}}=\frac43\cdot\pi\cdot2^3=\frac{32}{3}\pi.$[/tex]

Since the balls can be reshaped but not compressed, the maximum number of balls that can completely fit inside a cube is

[tex]\[\left\lfloor\frac{V_{\text{cube}}}{V_{\text{ball}}}\right\rfloor=\left\lfloor\frac{343}{\frac{32\pi}{3} }\right\rfloor.\][/tex]

An analogous equation can be created by factoring a quadratic equation. 5x^2 = (x-2) * (x+2) + 488 can give integers 9, 11,13.

In algebra, quadratic equation (from Latin quadratus 'square') is any equation that can be rearranged in standard form as

[tex]{ax^{2}+bx+c=0}[/tex]

where a 0 and x denotes an unknown and a, b, and c denote known numbers, Since there is no ax2 term, the equation is linear (and not quadratic) if a = 0 (and b 0). The coefficients of the equation, denoted by the numbers a, b, and c, are the quadratic coefficient, linear coefficient, and constant or free term, respectively.

The roots or zeros of the expression on the left-hand side of the equation are the values of x that fulfill the equation. There can only be two solutions to a quadratic problem. One claims that a problem is a double root if there is just one solution. There are either two real solutions, one real double root, two complex solutions that are complex conjugates of one another, or two real solutions if all the coefficients are real values. If complex roots are included, a quadratic equation will always have two roots; a double root counts as two. An analogous equation can be created by factoring a quadratic equation.

According to the formula, if 5x2 = x2 - 4 + 488, then 5x2 = x2 + 484.

For 4x2 = 484, subtract x2 from each side, resulting in x2 = 121.

For x = 11, square root each side.

TEST: 5*121 = 9*13 + 488, so 605 is equal to 117 plus 488.

The middle odd number, x, is equal to 11.
