In short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.

Given that, a set of data has a high-value outliner.

In simple terms, an outlier is an extremely high or extremely low data point relative to the nearest data point and the rest of the neighboring co-existing values in a data graph or dataset you're working with. Outliers are extreme values that stand out greatly from the overall pattern of values in a dataset or graph.

When you have an outlier that is higher then the bulk of the data, the standard deviation is larger then it would be without the outlier. If the outlier was lower than the bulk of data, then the standard deviation would again be larger then it would be without the outlier and the mean would go down when the outlier is removed. Where it differs is the fact that removing the outlier would result in an increase of the mean instead of a decrease.

Therefore, in short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.

For one real (double) root, set discriminant [tex]\( \Delta \)[/tex] to zero: [tex]\( 144 - 36k = 0 \)[/tex]. Solve to get [tex]\( k = 4 \)[/tex].

To find the value of [tex]\( k \)[/tex] so that the equation [tex]\( 9x^2 + 12x + k = 0 \)[/tex] has one real number (double) root, we use the discriminant [tex](\( \Delta \))[/tex] of the quadratic equation. For a double root, [tex]\( \Delta = 0 \)[/tex].

The discriminant is given by [tex]\( \Delta = b^2 - 4ac \)[/tex], where [tex]\( a = 9 \)[/tex], [tex]\( b = 12 \)[/tex], and [tex]\( c = k \)[/tex].

Substitute these values into the discriminant formula:

[tex]\[ \Delta = (12)^2 - 4(9)(k) \][/tex]

[tex]\[ = 144 - 36k \][/tex]

For a double root, [tex]\( \Delta = 0 \)[/tex], so:

[tex]\[ 144 - 36k = 0 \][/tex]

[tex]\[ 36k = 144 \][/tex]

[tex]\[ k = \frac{144}{36} \][/tex]

[tex]\[ k = 4 \][/tex]

Therefore, [tex]\( k = 4 \)[/tex] to have one real number (double) root.

B is the area of the base

L is the length of the prism

In this problem we have

[tex]B=2\frac{1}{8}\ units^{2}=\frac{8*2+1}{8}=\frac{17}{8}\ units^{2}[/tex]

[tex]L=4\ units[/tex]

Answer:

1/8 of the number of students

Step-by-step explanation:

1/4 + 1/3 + 1/8 + 1/6 =

= 6/24 + 8/24 + 3/24 + 4/24

= 21/24

= 7/8

7/8 of the class chose drinks.

1 - 7/8 = 8/8 - 7/8 = 1/8

That means that 1/8 did not have a drink.

Since we don't know the number of students in her class, we cannot tell the number of students who did not have a drink, but we do know it is 1/8 of the number of students.

Length of more string needed to fly the kite 10 feet higher is 15.55 ft.

The angle of elevation is the angle between the horizon and the line of sight. If the line of sight is above the horizon, the angle formed is the elevation angle.

Given,

Height of the string above the ground = 4 feet

Angle of elevation = 40°

length of the string = 90 ft

sin 40° = x/90

0.643 = (x)/90

x = 57.87 ft

For 10 ft higher, let the length be 90 + y

sin 40° = (57.87 + 10)/(90 + y)

0.643 = (57.87 + 10)/(90 + y)

57.87 + 0.643y = 57.87 + 10

0.643y = 10

y = 10/0.643

y = 15.55 ft

Hence, 15.55ft more string is needed to let out kite to fly 10 ft higher.

Final answer:

To find the extra string needed to raise the kite by 10ft, we can use trigonometry and set up an equation based on the sine function. By plugging in the values and solving the equation, we find that you would need 37.7ft of extra string.

Explanation:

To find how much more string you would need to let out for the kite to fly 10ft higher, we can use trigonometry. First, let's find the height of the kite above the ground when 90ft of string is let out. We can use the sine function: sin(40°) = height / 90ft. Rearranging the equation, we find height = sin(40°) * 90ft = 57.7ft. Now, to find the extra string needed to raise the kite by 10ft, we can set up a similar equation: sin(40°) = (height + 10ft) / (90ft + x), where x is the extra string. Rearranging the equation, we get x = ((height + 10ft) / sin(40°)) - 90ft. Plugging in the values, we have x = ((57.7ft + 10ft) / sin(40°)) - 90ft = 37.7ft.

Answer:

First polynomial minus the second polynomial:

3 x³ + x² + 7 x - 11.

Step-by-step explanation:

The question asks for the difference between the two cubic polynomials (maximum power of x is three.) As the other answerer mentioned, the question doesn't say anything about the value of x. In that case, the difference between the two polynomials will still be a polynomial about x.

The power x in the difference can be as high as three. Assume that to be a cubic polynomial.

? x³ + ? x² + ? x + ?.

What are the values of each coefficient?

For example, the coefficient in front of x³ in the difference is the difference between the coefficients of x³ in the two original polynomials.

Subtract the second coefficient from the first. 8 - 5 = 3. In other words, 3 is the value of the x³ coefficient in the difference.

3 x³ + ? x² + ? x + ?.

Repeat this step for the x² and x coefficients.

3 x³ + x² + 7x + ?.

The constant in the difference is the difference between the two constants.

-7 - 4 = -11.

Hence the difference:

3 x³ + x² + 7x - 11.

Alternatively, group the terms by the power of x:

(8 x³ - 2 x² + 5 x - 7) - (5 x³ - 3 x² - 2 x + 4)

= (8 x³ - 5 x³) + (-2 x² + 3 x²) + (5 x + 2 x) + (-7 - 4)

= 3 x³ + x² + 7 x - 11.

Answer:

2m^3n^3

Step-by-step explanation:

Final answer:

The greatest common factor of the expressions [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex] is [tex]2m^3n^3[/tex].

Explanation:

The question is asking for the greatest common factor (GCF) of the three algebraic expressions provided: [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex]. To find the GCF, we need to determine the highest powers of m and n that divide evenly into all three expressions.

For the variable m, the smallest exponent is 3 (in the term [tex]4m^3n^5[/tex]). For the variable n, the smallest exponent is 3 (in the term [tex]2m^5n^3[/tex]). Therefore, the GCF is [tex]2m^3n^3[/tex].

We also look at the numerical coefficients (16, 4, and 2) and find their GCF to be 2.

Answer:

14x + 4

Step-by-step explanation:

An equivalent expression is an expression which is equal. It can be a simplified form or expanded form. Here lets simplify by using the distributive property.

4(2x+1) - (-6x)

8x + 4 + 6x

14x + 4

This is the simplified equivalent form. It can also be written in expanded form as 2(7x + 2).
