what is a slope??????

The equation for the relationship between the number of bracelets made and the number of beads is y = 21x.

First, the rate of change

= (483 - 210) / (23 - 10)

= 273 / 13

= 21

So, the equation for the relationship between the number of bracelets made and the number of beads used.

(y - 210) = 21 (x-  10)

y - 210 = 21x - 210

y = 21x

29.5

Step-by-step explanation:

Arranging the values in ascending order we get

16 21 24 24 27 28 30 35

n = Number of values = 8

Rank is given by

\(\dfrac{\text{Percentile}}{100}\times (n+1)\)

\(=\dfrac{20}{100}(8+1)=1.8\)

Taking the fraction of the rank i.e., 0.8 and work out the weighted mean

\(0.8\times (21-16)+16=20\)

The 20th percentile is 20

\(\dfrac{25}{100}(8+1)=2.25\)

\(0.25(24-21)+21=21.75\)

The 25th percentile is 21.75

\(\dfrac{65}{100}(8+1)=5.85\)

\(0.85(28-27)+27=27.85\)

The 65th percentile is 27.85

\(\dfrac{75}{100}(8+1)=6.75\)

\(0.75(30-28)+28=29.5\)

The 75th percentile is 29.5

There are 210 ways that Janelle can choose 4 colors from 10 available colors for her art project.

Janelle needs to choose 4 colors out of 10 available colors for her art project. The order in which she chooses the colors does not matter. We can use the combination formula to determine the number of ways she can choose 4 colors from 10 available colors:

nCr = n! / r!(n - r)!

where n is the total number of colors available, r is the number of colors Janelle needs to choose, and ! denotes the factorial operation.

In this case, we have:

n = 10 (total number of colors available)

r = 4 (number of colors Janelle needs to choose)

Substituting these values into the formula, we get:

10C4 = 10! / 4!(10 - 4)!

= 10! / 4!6!

= (10 x 9 x 8 x 7) / (4 x 3 x 2 x 1)

= 210

Therefore, for her art assignment, Janelle can select 4 colors from a palette of 10 in 210 different ways.

The inequality on the number line is 5x -2 > -22 or 6x-7 < 11.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

The open circles on the number line shows that it does not include those value i.e., the values have less than and greater than.

So, from the number line the inequality is -4 < x < 3.

Now, 5x -2 > -22 and 6x-7 < 11

5x > -20 and 6x < 18

x > -4 and x<3.

x+5 >8 and 3+ 2x < -5

x >3 and x < -4.

so, the inequality is 5x -2 > -22 or 6x-7 < 11.

y=-2x+5 is the slope-intercept equation for a line that goes through the point (4,-3) and 5 is the value of b.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We have to find the slope-intercept equation for a line that goes through the point (4,-3)--with a slope of -2

m=-2

Now let us find the y intercept

-3=-2(4)+b

-3=-8+b

-3+8=b

5=b

Hence, y=-2x+5 is the slope-intercept equation for a line that goes through the point (4,-3) and 5 is the value of b.

The differentiable function f with the given properties is \(f(x)=4x^3-3x^2+10\).

What is a differentiable function:

A function with a differentiable value of one real variable is one whose domain contains a derivative. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.

The given properties for the differentiable function f are:

\((i) f'(x)=ax^2+bx\\ (ii) f'(1)=6, f''(1)=18\\ (iii) \int\limits^2_1 {f(x)} \, dx =18\)

From (i) we can get \(f''(x)=2ax+b\)

By substituting (ii) in (i) we will get:

a+b=6 and 2a+b=18. By solving these two equations we will get the following:

a=12, b=-6.

We will integrate (i) on both sides, we will get:

\(f(x)=\frac{ax^3}{3} +\frac{bx^2}{2} +c\) where c is the integration constant.

In this equation, we will substitute a,b.

\(f(x)=\frac{12x^3}{3} +\frac{-6x^2}{2} +c\\ \\ f(x)= 4x^3-3x^2+c\)...................(iv)

Now we will substitute (iv) in (iii), and we will get:

\(\int\limits^2_1 {( 4x^3-3x^2+c)} \, dx =18\\ \\ (2^4-2^3+2c)-(1^4-1^3+c)=18\\ \\c=10\)

Therefore \(f(x)=4x^3-3x^2+10\).

Complete question:

Let f be a differentiable function, defined for all real numbers x, with the following properties. Find f(x). Show your work.

The probability of Event A is 1/360 and the probability of Event B is 1/15.

For Event A, we can calculate the probability by considering the order in which the acts are scheduled.

There are 6 acts, so there are 6 possible choices for the first act. After the first act is scheduled, there are 5 remaining acts, so there are 5 possible choices for the second act.

Similarly, there are 4 possible choices for the third act, and 3 possible choices for the fourth act.

Finally, there are 2 possible choices for the fifth act, and only 1 choice remains for the last act.

Therefore, the total number of possible ways to schedule all 6 acts is:

6 x 5 x 4 x 3 x 2 x 1 = 720

Since we are only interested in one specific order of the first four acts, we need to count the number of ways to schedule the remaining two acts after the first four have been scheduled in the desired order.

There are 2 remaining acts, so there are 2 possible choices for the fifth act.

Only one act remains for the last slot.

Therefore, the total number of ways to schedule all 6 acts such that the acrobat is first, the singer is second, the violinist is third, and the whistler is fourth is:

1 x 1 x 1 x 1 x 2 x 1 = 2

Thus, the probability of Event A is:

P(A) = 2/720 = 1/360

For Event B, we want to count the number of ways to schedule the first four acts as the whistler, the acrobat, the guitarist, and the dancer, in any order.

There are 4 acts, so there are 4 possible choices for the first act. After the first act is scheduled, there are 3 remaining acts, so there are 3 possible choices for the second act.

Similarly, there are 2 possible choices for the third act, and only one choice remains for the fourth act.

Therefore, the total number of possible ways to schedule the first four acts is:

4 x 3 x 2 x 1 = 24

Since we do not care about the order in which the last two acts are scheduled, we can simply choose any two acts from the remaining 2. There are 2 ways to do this.

Therefore, the total number of ways to schedule all 6 acts such that the first four acts are the whistler, the acrobat, the guitarist, and the dancer, in any order is:

24 x 2 = 48

Thus, the probability of Event B is:

P(B) = 48/720 = 1/15

Answer:

middle set of data

Step-by-step explanation:

For given function function f(x)=-x+3-2, the domain is x > -3 and the range is y ≤ 2. So, correct option is D.

The function f(x)=-x+3-2 is a linear function in the form y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is -1 and the y-intercept is 1. Therefore, the graph of the function is a straight line that intersects the y-axis at (0,1) and has a slope of -1, meaning that it decreases by 1 for every 1 unit increase in x.

The domain of the function is the set of all possible values of x for which the function is defined. Since there are no restrictions on the value of x in the equation f(x)=-x+3-2, the domain is all real numbers, or (-∞, ∞).

The range of the function is the set of all possible values of y that the function can output. In this case, the lowest possible value of y occurs when x approaches positive infinity, and the highest possible value of y occurs when x approaches negative infinity. Therefore, the range is all real numbers less than or equal to 2, or y ≤ 2.

So, the domain is x ∈ (-∞, ∞) and the range is y ≤ 2. Alternatively, the domain can also be expressed as x > -3, since that is the minimum value of x at which the function is defined.

Correct option is D.

The proof below shows that the triangle is similar to the original triangle is as shown below.

Similar triangles are defined as the triangles that have the same shape, but their sizes may vary.

We are told that a straight line that is parallel to one of the sides of a given triangle intersects its other two sides. Let the straight line be DE and let the line it is parallel to be BC as shown in the triangle attached. Thus, DE∥BC

In the two triangles formed △ADE and △ABC, we can say that;

∠DAE = ∠BAC because they are common angles.

We can also say that;

∠ADE = ∠ABC [This is because DE∥BC which means ∠ADE and ∠ABC are corresponding angles and as such we say that they are congruent.

By the same concept, we can also say that ∠AED=∠ACB

∴△ADE ∼ △ABC

In similar triangles, corresponding sides are in the same ratio and as such; AD/AB = AE/AC

Thus, we can also simplify this to;

AD/DB = AE/EC

Thus, It is proved that if a line is drawn parallel to one side of a triangle intersecting the other two sides, then it divides the two sides in the same ratio.

Step-by-step explanation:

From the given information the first step to carry out is to find the partial fraction of the given equation; i.e.

\(\dfrac{s}{(s-4)(s-5)(s-20)}= \dfrac{A}{s-4}+\dfrac{B}{s-5}+\dfrac{C}{s-20}\)

After finding the partial fraction; we get:

\(s= s^2(A+B+C)+s(-2A-24B-25C)+20A+80B+100C\)

By solving this; we get:

\(A =\dfrac{1}{12}\ ; \ B = -\dfrac{1}{3} \ ; \ C= \dfrac{1}{4}\)

Thus;  the above equation can be re-written as:

\(\dfrac{s}{(s-20)(s-5)(s-4)}= \dfrac{\dfrac{1}{12}}{s-20}+\dfrac{-\dfrac{1}{3} }{s-5}+\dfrac{\dfrac{1}{4}}{s-4}\)

The percent symbol (%) is a shorthand way to write "divided by 100" (/100). The percent can be changed to a decimal by making that substitution.

  8% = 8/100 = 0.08

  80% = 80/100 = 0.80

  800% = 800/100 = 8.00

Effectively, the change to a decimal is made by moving the decimal point two places to the left. Richard's strategy only works if the percentage has 2 digits left of its decimal point. It does not work in the general case.
