The arithmetic mean is 59.

What is arithmetic mean?

It is the sum of collection of numbers divided by the count of the numbers.

Conider AB is the nuber satisfying the condition. Hence,

[tex]10A+B=A+B+A\times B\\9A=A\times B\\[/tex]

Since AB is a two digit number hence, [tex]A\neq 0\\[/tex]. Hence, divide both sides by [tex]A[/tex].

[tex]9=B[/tex]

Hence, B is 9 and A can take any value from 1 to 9.

Hence, numbers are 19, 29, 39, 49, 59, 69, 79, 89,99.

Now, calculate arithmetic mean as follows:

[tex]AM=\frac{Sum \ of \ numbes}{Count \ of \ numbers}\\=\frac{19+29+39+49+59+69+79+89+99}{9}\\=59[/tex]

Hence, arithmetic mean of numbers is 59.

Answer:

X=ℝ, Y=ℝ

Step-by-step explanation:

Parallel means they have the same slope so it can be anything on the x-axis, perpendicular meaning opposite slope which is y=.

For the given parallel lines with transversal ,and the pair of interior angles 72° and (7x +24)°, the value of x = 12°.

As given in the question,

Two parallel lines with transversal are given.

72° and (7x +24)°are pair of interior angles

Simplify the given relation to get the value of x we have,

72° + (7x +24)° =180°

⇒ 7x + (72 +24)° =180°

⇒ 7x + 96° = 180°

⇒ 7x = 180° - 96°

⇒ 7x = 84°

⇒ x = 84° /7

⇒ x = 12°

Therefore, for the given parallel lines with transversal ,and the pair of interior angles 72° and (7x +24)°, the value of x = 12°.

Since there are 128 fluid ounces in one gallon, we need to divide 14 by 128 to change ounces into gallons.

Since there are 60 minutes per hour, we need to multiply 14 by 60 to change per minute into per hour.

Combining these:  14 fl oz / min x (1 gal / 128 fl oz) x (60 min / hr)  =  6.5625 gal per hour.

Written as a mixed fraction:  6 9/16 gal per hour.

y-intercept= 0

asymptote =[tex]lim_{n}[/tex]→-0 (8/x) = -∞

[tex]lim_{n}[/tex]→+0 (8/x) = +∞

range = R : { x ∈ R / {0} }

What is Range ?

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

I think the formula is:

f(x) = 8/x

(You wrote 8x; since a linear function has no asymptotes and you wrote 8x, I'm assuming the true function was 8/x.)

The amount that makes f(x) equal to 0 is the y-intercept.

Keep in mind that there is no value of x such that 8/x = 0 (because the quotient cannot be zero if the numerator is never zero).

Therefore, there is no y-intercept.

The asymmetry:

These are the four:

If the negative side of x tends to zero, then 8/x tends to negative infinity.

If x from the positive side approaches to zero, then 8/x tends to positive infinity.

These two asymptotes are expressed as follows:

[tex]lim_{n}[/tex]→-0 (8/x) = -∞

[tex]lim_{n}[/tex]→+0 (8/x) = +∞

Additionally, there are two cases where x tends to plus infinity (and 8/x goes to zero) and when x tends to minus infinity, where the function tends to zero once more. These two cases are denoted by the formulas:

[tex]lim_{n}[/tex]→-∞ (8/x) = -∞

[tex]lim_{n}[/tex]→∞ (8/x) = +∞

Lastly, the scope:

Only on limitations, y never reaches the following value:

y = 0

If so, the set of all real numbers excluding zero is the range, or

R : { x ∈ R / {0} }

Hence, y-intercept= 0

asymptote =[tex]lim_{n}[/tex]→-0 (8/x) = -∞

Answer:

I think it's (4,5)

Step-by-step explanation:

Step-by-step explanation:

79 degrees plus X would make 180 degrees, because these two angles make up a straight angle.

So, 79 + X = 180

    -79          -79

         X=101 degrees.

Y is 79 degrees because it is an alternate interior angle to the other 79 degree angle.

Z is 101 degrees because X and Z are corresponding angles, which means they are equal.

If Z is 101 degrees, Y must be 79 degrees because Y and X make up a straight angle.

Answer:

X is 101 degrees. Y is 79 degrees. Z is 101 degrees.

It is true to state that segments 6 5 8 could form a triangle. Where AC = 6, CB =5 and BA = 8. See the explanation for the same below.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. Triangle ABC denotes a triangle with vertices A, B, and C.

The total lengths of any two sides must always be larger than the length of the third side in order to make a triangle.

This is shown as follows:

6 + 5 = 11 > 8

5 + 8 = 13 > 6

8 + 6 = 14 > 5

Answer:

================

Find the midpoint of the segment and its slope to determine the perpendicular line passing through the midpoint.

The midpoint has coordinates:

The slope:

We know perpendicular lines have opposite/reciprocal slopes.

So the slope of the perpendicular bisector is:

Use the coordinates of the midpoint and point-slope equation to determine the line:

Answer:

[tex]y=-\dfrac{5}{2}x+9[/tex]

Step-by-step explanation:

A perpendicular bisector is a line that intersects another line segment perpendicularly and divides it into two equal parts.

Given endpoints of the line segment:

Substitute the given endpoints into the slope formula to find the slope of the line segment:

[tex]\implies \textsf{Slope $m$}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{6-2}{7-(-3)}=\dfrac{4}{10}=\dfrac{2}{5}[/tex]

If two lines are perpendicular to each other, their slopes are negative reciprocals.  

Therefore, the slope of the perpendicular line is -⁵/₂.

Find the midpoint of the given line segment by substituting the given endpoints into the midpoint formula:

[tex]\implies \textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)[/tex]

[tex]\implies \textsf{Midpoint}=\left(\dfrac{7-3}{2},\dfrac{6+2}{2}\right)[/tex]

[tex]\implies \textsf{Midpoint}=\left(\dfrac{4}{2},\dfrac{8}{2}\right)[/tex]

[tex]\implies \textsf{Midpoint}=\left(2,4\right)[/tex]

To find the equation of the perpendicular bisector, substitute the found slope and midpoint into the point-slope form of a linear equation:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-4=-\dfrac{5}{2}(x-2)[/tex]

[tex]\implies y-4=-\dfrac{5}{2}x+5[/tex]

[tex]\implies y=-\dfrac{5}{2}x+9[/tex]

Therefore, the equation for the perpendicular bisector of the line segment whose endpoints are (-3, 2) and (7, 6) is:

[tex]\boxed{y=-\dfrac{5}{2}x+9}[/tex]

The equation of the parabola in intercept form exists

y = -2/7(x + 14)(x + 2).

The intercept form exists y = a(x - r)(x - s), where r and s exists the x-intercepts on the graph. The intercept form will tell us if there exists two x-intercepts, one x-intercept, or no x-intercepts.

Let x-intercepts of -14 and -2; passes through (-16, -8)

The equation of the parabola in intercept form y = a(x - r)(x - s)

substitute the values in the above equation, and we get

-8 = a(-16 + 14)(-16 + 2)

The probability of drawing 3 blacks will be:

Answer:

b x 8 = 40 and 40 / 8 =b

Step-by-step explanation:

well, 8 charms makes one bracelet, so add up 8 until you run out of charms:

We only have 40 charms, so we can make 5 bracelets!

Now, plug this number (5) back into the equations:

b x 8 = 40

(5) x 8 = 40

40 = 40

this checks out!

40 - 8 = b

40 - 8 = (5)

32 = 5

32 does not equal 5, so this equation doesn't work.

40 / 8 = b

40 / 8 = (5)

5 = 5

This equation works :)

b + 8 = 40

(5) + 8 = 40

13 = 40

13 does not equal 40, so this is also a bad equation..

since b x 8 = 40 and 40 / 8 = b both produced the right results, we know those two are our answers!
