Answer:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

The mode is the number that occurs most often in a data set.

use scientific calculator ❗

Answer:

f(x) → f(x - b) means shift the function b units to right

Therefore x² → (x - 2)² means the function is moved 2 units to the right.

f(x) → a f(x) means a vertical stretch

Therefore (x - 2)² → 2(x - 2)² means the function stretched vertically by a scale factor of 2.

f(x) → f(x) + b means shift the function b units up

Therefore 2(x - 2)² + 1 means the function is moved 1 unit up.

Answer:

If a and b are either both positive integers or both negative integers

Step-by-step explanation:

If a and b are both positive integers (a>0 and b>0), then the product will obviously be a positive number. Additionally, if both terms are negative (a<0 and b<0), the product of two negative integers is positive and will satisfy the condition.

Integers are numbers without decimal points.

The conditions that would make [tex]\mathbf{a \times b > 0}[/tex] are: a, b > 0 or a, b < 0

From the question, we have:

[tex]\mathbf{a \times b > 0}[/tex]

Divide both sides by a

[tex]\mathbf{b > 0}[/tex]

Divide both sides by b

[tex]\mathbf{a > 0}[/tex]

The above means that, for [tex]\mathbf{a \times b > 0}[/tex] to be true, then [tex]\mathbf{a > 0}[/tex] and [tex]\mathbf{b > 0}[/tex]

Another possible condition is that:

[tex]\mathbf{a \times b > 0}[/tex]

Divide both sides by -a

[tex]\mathbf{b<0}[/tex]

Divide both sides by -b

[tex]\mathbf{a<0}[/tex]

The above means that, for [tex]\mathbf{a \times b > 0}[/tex] to be true, then [tex]\mathbf{a<0}[/tex] and [tex]\mathbf{b<0}[/tex]

Hence, the condition that would make [tex]\mathbf{a \times b > 0}[/tex] true is that: a and b have the same sign

Answer:

a is the correct option

Step-by-step explanation:

The value of the correlation coefficient is -0.993, The correct option is A.

The coefficient used to determine how strong is the relation between the two variables in the data set is the Correlation Coefficient.

The correlation coefficient is determined by using the following formula

[tex]\rm r = \dfrac{ n(\sum xy) - \sum x\sum y}{\sqrt {n\sum x^2 - (\sum x)^2 }\sqrt{n\sum y^2 - (\sum y)^2}}[/tex]

The values of the required data will be calculated from the data given

n = 4 rows

∑x = 42

∑y = 44.37

∑xy = 461.3

∑x^2 = 446

∑y^2 = 494

Putting the values in the equation of correlation coefficient:

r = -0.993

Therefore, the value of the correlation coefficient is -0.993, The correct option is A.

Answer:

Equation is 4 p-3=11

Step-by-step explanation:

Barbara is buying 4 binders each cost same amount.

Let the cost of 1 binder is '$p'.

So, cost of 4 binders = $4 p.

Now, a coupon that gives her $3 off.

So, Barb needs to pay 4 p-3 dollars.

Barb pays a total of $11 when the value of the coupon is subtracted.

So, we can set up equation as

Answer:

12

Step-by-step explanation:

perimeter is (a+b) x 2 = 46

a is width and b is length

a=11

(11+b) x 2 = 46

22 + 2b = 46

2b = 24

b = 12 ( length )

Solution:

We know that:

Substitute the width in the expression:

Simplify the LHS:

Subtract 22 both sides:

Divide 2 both sides:

Function assigns one element of one set to the other specific element of another set. The quotient of the fraction [tex]\dfrac{2}{\sqrt{13}+\sqrt{11}}[/tex] is [tex]{\sqrt{13}-\sqrt{11}}[/tex].

A function assigns the value of each element of one set to the other specific element of another set.

As the fraction is given to us,

[tex]\dfrac{2}{\sqrt{13}+\sqrt{11}}[/tex]

Rationalizing the fraction we will get,

[tex]=\dfrac{2}{\sqrt{13}+\sqrt{11}} \times \dfrac{{\sqrt{13}-\sqrt{11}}}{{\sqrt{13}-\sqrt{11}}}\\\\= \dfrac{2({\sqrt{13}-\sqrt{11}})}{(\sqrt{13})^2-(\sqrt{11})^2}\\\\= \dfrac{2({\sqrt{13}-\sqrt{11}})}{13-11}\\\\=\dfrac{2({\sqrt{13}-\sqrt{11}})}{2}[/tex]

Now, if we divide the numerator by the denominator to get the quotient we will get,

[tex]= \dfrac{2({\sqrt{13}-\sqrt{11}})}{2}\\\\={2({\sqrt{13}-\sqrt{11}})}\div 2\\\\={\sqrt{13}-\sqrt{11}}[/tex]

Hence, the quotient of the fraction [tex]\dfrac{2}{\sqrt{13}+\sqrt{11}}[/tex] is [tex]{\sqrt{13}-\sqrt{11}}[/tex].
