Answer:

D(30,60)

Step-by-step explanation:

It was way outside the other points that are around the line.

The point (30,60) is a high leverage point on the regression plot.

High leverage points are those that are extreme but follow the regression equation's trend.

High leverage points are distinct from outliers, which deviate from the graph's or plot's pattern or trend.

Looking closely at the regression plot, the coordinate (30,60) follows the trend of the plot, however, it is farther from the majority of the points on the graph.

Hence, the point (30,60) is a high leverage point on the regression plot.

Money is anything generally accepted as final payment for goods, services, and debt.

First, let us understand the money supply:

The money supply is the total amount of currency and liquid assets in a country's economy on the day measured. Cash and deposits that can be utilized virtually as quickly as cash are roughly included in the money supply.

Money supply refers to the total amount of money held by the public for a particular point.

Governments print paper money and coins through a combination of central banks and treasuries. Bank regulators impact the money supply available to the public by requiring banks to retain reserves, determining how to grant credit, and other monetary matters.

We can say that we are using the money for goods purchasing, service requirements, and for the debt taken.

Thus, money is anything generally accepted as final payment for goods, services, and debt.

Factor of the following polynomial function is (x-1)(x+7)(x-4+4i)(x-4-4i).

If 4-4i is a zero, then is its conjugate, 4+4i, as well.

Next 4-4i and 4+4i are zeros, this means that

x^4-2x^3-23x^2+248x-224=(x-4+4i)(x-4-4i)g(x), (A)

where g(x) is a degree 2 polynomial.

Since (x-4+4i)(x-4-4i)=x^2-8x+32,(A) is equivalent to

x^4-2x^3-23x^2+248x-224=(x^2-8x+32)g(x) (B)

Now dividing the LHS of (B) by x^2-8x+32 you find that g(x)=x^2+6x-7.

So,

x^4-2x^3-23x^2+248x-224=(x^2-8x+32)(x^2+6x-7) (C)

It is easy to see that x^2+6x-7=(x-1)(x+7).

The function [tex]24x^{3}[/tex] + [tex]Ax^{2}[/tex] -3x + B results to the equation A + 4B = 114 hen f(x) is divided by (2x - 1) and with a remainder 30.

The Remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.

For example, 10 is not exactly divided by 3. Since the closest value, we can get 3 x 3 = 9.

Hence, 10 ÷ 3 → 3 R 1, where 3 is the quotient and 1 is the remainder.

if ( 2x - 1) divides  [tex]24x^{3}[/tex] + [tex]Ax^{2}[/tex] -3x + B with a remainder 30, it means if x = 1/2 when substituted should give 30.

The substitute x = 1/2 into the given function and equate it to 30

24[tex](\frac{1}{2}) ^{3}[/tex] + A[tex](\frac{1}{2}) ^{2}[/tex] - 3(1/2) + B = 30

24[tex](\frac{1}{8})[/tex] + A[tex](\frac{1}{4})[/tex] - 3/2 + B = 30

3 + A/4 -3/2 + B = 30

multiply through by 4

Answer:

X-intercept: (6, 0)

Y-intercept: (0, -9)

Step-by-step explanation:

Required: Find the X and Y intercept of the standard from equation:

-3x + 2y = -18.

We shall write equation in the form [tex]\frac{x}{a} +\frac{y}{b} =1[/tex] and find the intercepts on X and Y axis:

-3x + 2y = -18

∴ -3x + 2y = -18

∴ -3x/-18 + 2y/-18 = 1

∴ x/6 + y/-9 = 1

Comparing this equation with [tex]\frac{x}{a} +\frac{y}{b} =1[/tex], we get:

intercept of X-axis = a = 6

intercept of Y-axis = b = -9

Thanks.

Answer:

The y-intercept for the line is ( 0, -9 ).

Hope this helps!

Step-by-step explanation:

The y-intercept is where the graph intercepts the y-axis and is the y-value of the point, ( x, y ).

Value of n is 3 when a line that includes the points (n, -9) and (5, 7) has a slope of 8.

A line's steepness is indicated by its slope. Any line's slope is constant along its length. The direction of the line on the coordinate plane can also be determined by the slope. A line's graph can be used to determine slope, or the coordinates of any two points on a line can be used.

Given,

Slope = 8

Points = (n,-9) and (5,7)

Formula:

Slope = y₂ - y₁/ x₂ - x₁

8 = 7 -(-9)/ 5-n

Cross multiplying,

8(5 - n) = 7 +9

(5-n) = 16/8

5 -n = 2

n = 3

Value of n is 3 when a line that includes the points (n, -9) and (5, 7) has a slope of 8.

The other three length are 9km,12km,14km as mode is 12km

What is mode?

The value that appears most frequently in a set of values is referred to as the mode. It is the value that shows up the most frequently. The value that consistently appears in a given set is known as the mode in statistics. The mode or modal value is the value or number that appears most frequently in a data set and has a high frequency. Along with mean and median, there are three other ways to measure central tendency.

The mean, median, and mode all have the same values for this distribution. This indicates that this value—the one that appears the most frequently in the data—is the average, the centre, and the mode.

Four lengths have a mode of 12 km and a range of 5 km.

The range is the largest number minus the smallest number.

As mode is 12 so one more number is 12 as well.

Now another number given 14km, so the last number is (14-5 = 9)

The average, the median, and the range of the given data are 75, 75.7, and 25.3, respectively.

We are given the weights of five people that go to the gymnasium to exercise. The weights are 58 kg, 75 kg, 83.3 kg, 83 kg, and 75.7 kg. The average is found by dividing the sum of all the weights by the number of persons.

A = (58 + 75 + 83.3 + 83 + 75.7)/5 = 375/5 = 75

Hence, the average weight is 75 kg. The median weight is the center value when all the weights are arranged in ascending or descending order. The weights arranged in the ascending order are 58 < 75 < 75.7 < 83 < 83.3. The third weight lies in the center. Hence, the median weight is 75.7 kg. The range of the data is the difference between the maximum and the minimum weight. The maximum and minimum weights are 83.3 kg and 58 kg, respectively.

17.16 is the estimated 22% of 78.

What is estimation?

To make calculations simpler and more realistic, estimation of a number refers to a plausible assumption of the actual value.

Estimation is the process of approximating a quantity with the necessary accuracy.

The result is quickly and roughly determined by rounding off the numbers used in the calculation.

Assumedly, 22% of 78.

78 comes out to 80.

Therefore, cut 22% to 1/5.

78 through 80 is increased.

80/5 = 16( close to 17.16) ( approximate to 17.16)

Or

22% = 22/100

22% of 78 = 22 × 78 /100 = 1716/100

= 17.16.

As a result, 17.16 is the estimated 22% of 78.

In implicit differentiation, what we do is that we differentiate each side of an equation using the two variables (usually x and y) by treating one of the variables to be as a function of the other.

We are given the equation;

4x = 4y² + 1

Thus, first differentiation gives;

4 = 8y(dy/dx)

y(dy/dx) = 0.5

Answer:

The length of the straw in the simplest radical form is [tex]2\sqrt{30}[/tex] inches

Step-by-step explanation:

The length of the straw can be calculated as follow

The first step is to calculate the diagonal of the base of the rectangular box  by using Pythagorean theorem

[tex]c^{2}=a^{2}+b^{2}[/tex]

Where [tex]c[/tex] is the base diagonal or the hypotenuse, [tex]a[/tex] is the short leg, [tex]b[/tex] is the long leg

Substitute [tex]2[/tex] for [tex]a[/tex], [tex]4[/tex] for [tex]b[/tex] in the Pythagorean theorem

[tex]c^{2}=2^{2}+4^{2}[/tex]

Simplify the right side of the equation

[tex]c^{2}=4+16[/tex]

[tex]c^{2}=20[/tex]

Take the square root of the right side to get the value of [tex]c[/tex]

[tex]c=\sqrt{20}[/tex]

Factor [tex]20[/tex] by [tex]4[/tex]

[tex]c=\sqrt{4\times 5}[/tex]

Substitute [tex]2^{2}[/tex] for 4

[tex]c=\sqrt{2^{2}\times 5}[/tex]

Rewrite the value of [tex]c[/tex] in the simplest radical form

[tex]c=2\sqrt{5}[/tex]

Since the value of [tex]c[/tex] is [tex]2\sqrt{5}[/tex], then the length of the diagonal of the base is

[tex]2\sqrt{5}[/tex] inches

The second step is to calculate the length of the straw by using Pythagorean theorem

[tex]c^{2}=a^{2}+b^{2}[/tex]

Where [tex]c[/tex] is the diagonal from the bottom left corner to the top right back corner or the hypotenuse, [tex]a[/tex] is the short leg, [tex]b[/tex] is the long leg

Substitute [tex]2\sqrt{5}[/tex] for [tex]a[/tex], [tex]10[/tex] for [tex]b[/tex] in the Pythagorean theorem

[tex]c^{2}=(2\sqrt{5})^{2}+10^{2}[/tex]

Simplify the right side of the equation

[tex]c^{2}=20+100[/tex]

[tex]c^{2}=120[/tex]

Take the square root of the right side to get the value of [tex]c[/tex]

[tex]c=\sqrt{120}[/tex]

Factor [tex]120[/tex] by [tex]4[/tex]

[tex]c=\sqrt{4\times 30}[/tex]

Substitute [tex]2^{2}[/tex] for 4

[tex]c=\sqrt{2^{2}\times 30}[/tex]

Rewrite the value of [tex]c[/tex] in the simplest radical form

[tex]c=2\sqrt{30}[/tex]

Since the value of [tex]c[/tex] is [tex]2\sqrt{30}[/tex], then the length of the diagonal from the bottom left corner to the top right back corner or the hypotenuse is

[tex]2\sqrt{30}[/tex] inches

Since the length of the diagonal from the bottom left corner to the top right back corner is [tex]2\sqrt{30}[/tex] inches, then the length of the straw is [tex]2\sqrt{30}[/tex] inches
