A correlation coefficient is a numerical index that reflects the relationship between two variables.

The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

The given blank in the sentence can be filled with two variables.

Hence, A correlation coefficient is a numerical index that reflects the relationship between two variables.

Answer: Find details in the picture. The answer is 4.9

Step-by-step explanation:

The stem and leaf plot is an illustration of graphs and charts.

The number of days of temperatures displayed on the stem and leaf plot is 10

The stem and leaf plot is given as:

Stem            Leaf

4                   9

5                   2  4   4  6  8

6                   0   1

7                   2   3

To determine the number of days, we simply count the number of leaves on the plot.

The leaves on the plot are:

Leaves: 9, 2, 4, 4, 6, 8, 0, 1, 2 and 3

The number of leaves is:

Count = 10

Hence, the number of days of temperatures displayed on the stem and leaf plot is 10

Answer:

F. 12

Step-by-step explanation:

There are two right triangles.

Hence, we can solve for the missing side using the Pythagorean Theorem using one of these triangles.

Let's take the left one.

The length of the altitude is 12.

The correct option is : F. 12

The length of an altitude is 12 units.

The correct option is 12.

Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle is equal to the sum of the squares of the other two sides.

As per the information provided, it is given that the triangle is an equilateral triangle.

The side of the triangle is 8√3 units.

To find the length of the altitude of the equilateral triangle:

Let the length of altitude is h units.

Then, as per Pythagoras' theorem,

h² =  (8√3)²- (4√3)²

h² = -16(3) + 64(3)

h = -48 + 192

h² = 144

h = 12

Therefore, h = 12 units.

Check the picture below.

we have three sides, let's look at the two smaller sides first.

check picture atop

if we move the sides closer and ever closer to each other, to the extent that one is right on top of the other, what is the length of the red side?  Well, assuming the two smaller sides are one pancaked on top of the other, the red side will be as long as 8 - 3 = 5.  However, the sides can't be on top of each other, because if that's so, we have a flat-line, and thus we wouldn't have a triangle.  So whatever the third side may be, it must be greater than 5.

check picture below

Now, if we move the sides away from each other, farther and farther to the extent that one is parallel to the other, then the third side will just be as long as 3 + 8 = 11.  However, we can't do that, because if that were to happen, we again will have a flat-line and not a triangle.  So whatever the third side may be, it must be less than 11.

well, needless to say, the 16 cm side, is outside that range, so, hmmm no dice.

[tex]y + z + 90 = 180 \\ y + z = 90 \\ 36 + z = 90 \\ z = 90 - 36 \\ z = 54[/tex]

We are given the function to differentiate:

Do take natural log on both sides, then we will be having

An expression is defined as a set of numbers, variables, and mathematical operations. The polynomial expression that represents the sum of cubes is (s+6)(s²-6s+36).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The sum of the cubes of a polynomial expression can be written as,

[tex]a^3+b^3=(a+b)(a^2-ab+b^2)[/tex]

Therefore, we need to find the polynomial expression which looks similar to the above expression,

[tex]s^3+6^3=(s+6)(s^2-6s+36)[/tex]

Step-by-step explanation:

When we divide fractions we multiply instead since it's the opposite of division and we do the reciprocal. Reciprocal means we flip the fraction from 1/3 to 3/1

So:

4÷1/3 would become 4×3/1

4×3/1 is the same as 4×3

So:

4×3=12

We have the equation [tex]\sf -11=t-5}[/tex]. And what we need to do is solve for the variable, t.

                                            ↪

To solve for the variable, we should ensure that the variable we need to solve for is all by itself on one side of the equation.

T is not all by itself, [tex]\because[/tex] 5 is subtracted from it.

So what do we do to "remove" that 5 from there? Wouldn't it be great if there was a zero instead of the -5?

We can make that happen by adding 5 to both sides.

We add 5.

[tex]\sf -11=t-5+5}\\-11=t+0}\\-11=t[/tex]

[tex]\bullet[/tex] However, we also need to add 5 to the other side.

[tex]\sf -11+5=t}[/tex]

Simplify!

[tex]\sf -6=t}[/tex]

NOW the variable, t, is all by itself.

                                      ↪

Tip: Why not check your work and make sure there are no mistakes?

We can proof-read, but we can also do this:

[tex]\sf -11=-6-5}[/tex]. Upon simplification, we obtain

[tex]\sf -11=-11[/tex]

Since both sides (the left hand side, l.h.s. and  the right hand side, r.h.s. are the same, our solution, t=-6, is correct. Great job!

The number of times Leah is expected to select a pen that is red or green is 460 and the expression is 23/40 * 800

The distribution of the pen is given as:

Red = 5

Green = 18

Blue = 17

The number of red or green pen is:

Red or green = 5 + 18

Evaluate

Red or green = 23

In a selection of 800 pen, the expected number of red or green pen is:

E(x) = 23/(5 + 18 + 17) * 800

Evaluate the sum

E(x) = 23/40 * 800

Evaluate the expression

E(x) = 460

Answer:

Step-by-step explanation:

Given: 190x + 700 = 1,460

1. Subtract 700 from both sides:

190x + 700 - 700 = 1,460 - 700

190x = 760

2. Divide both sides by 190 to isolate x:

190x ÷ 190 = 760 ÷ 190

x = 4
