If i= square root of -1, what is the value of i^3

Answer:

16 elements

0 elements

Step-by-step explanation:

U = { 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 }

Let sets A , B , and C be subsets of U , where:

A = { 2 , 3 , 5 , 6 , 7 }

B = { 1 , 3 , 9 , 10 , 11 , 14 }

C = { 5 , 9 , 12 , 13 , 15 }

(A U B U C) = elements in either A, or B or C

(A U B U C) = {1,2,3,5,6,7,9,10,11,12,13,14,15}

(A U B U C) n (A U B U C) = elements on both intersecting set ; this will contain the same set as (A U B U C) are the same.

Number of elements = 13

(A n B n C) = elements occurring in both A, B and C

(A n B n C) = {} = empty set

(A n B n C) n (A n B n C) = {} = 0

Answer:

[tex]x=-7, \\x=7[/tex]

Step-by-step explanation:

Given [tex]3x^2-7=140[/tex], our goal is to isolate [tex]x[/tex].

Start by adding 7 to both sides:

[tex]3x^2=147[/tex]

Divide both sides by 3:

[tex]x^2=49[/tex]

Take the square root of both sides:

[tex]x=\pm \sqrt{49}=\pm 7[/tex]

Recall that [tex]7^2=(-7)^2=49[/tex].

Thus, we have:

[tex]x=-7, \\x=7[/tex]

Answer:

3

Step-by-step explanation:

To find the median, first we have to put the data in ascending order:

1, 2, 3, 3, 5, 11, 12

The median is the middle number. In this case, that is 3.

The median of the data "The number of girls per classroom" which has values as 11, 3, 1, 12, 5, 3, 2 is 3.

To find the median of the given data, we first need to arrange the numbers in ascending order:

1, 2, 3, 3, 5, 11, 12

The median is the middle value when the data is arranged in ascending order. In this case, since the total number of data points is odd (7 data points), there is one middle value. The median is the fourth value in the ordered list, which is 3.

The median is a measure of central tendency that represents the middle value in a dataset. It is often used to describe the typical or central value of a set of data and is particularly useful when dealing with skewed distributions or outliers.

In this case, the median of 3 tells us that, when sorted in ascending order, the middle value of the number of girls per classroom is 3, which gives us an indication of the central tendency of the data.

Answer:

D. The mean will shift to the left.

Step-by-step explanation:

Given that the price range of the car is between $5000 and $45000 ;

Hence, if the demand for cars that cost less than $5000 is in high demand, such that about 200 cars was sold ; This will lead to a shift in the mean price of car, $5000 towards the $5000 value. Since $5000 is to the left, then the mean price will shift to the left of the distribution.

The question is incomplete, as the required histograms are not provided; however, the general explanation is as follows.

(a) If any of the histograms has more bars at the left hand side, then it means that the distribution is skewed left.

(b) If any of the histograms has more bars at the right hand side, then it means that the distribution is skewed right.

(c) If any of the histograms has appears to have increasing number of bars at the middle, then it means the such histogram is symmetrical.

Use the above illustration to answer your question.

Answer:

x ≈ 10.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos42° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{14}[/tex] ( multiply both sides by 14 )

14 × cos42° = x , then

x ≈ 10.4 ( to the nearest tenth )

The volume of the sphere is V = 113.097 cm³

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the radius of the sphere be r = 3 cm

Let the volume of the sphere be V

The formula for the volume of a sphere is:

V = (4/3)πr³

where r is the radius of the sphere and π (pi) is a mathematical constant approximately equal to 3.14159.

Substituting r = 3 cm into the formula, we get:

V = (4/3)π(3 cm)³

V = (4/3)π(27 cm³)

V = (4/3)(3.14159)(27 cm³)

V = 113.097 cm³

Hence , the volume of the sphere is 113.097 cm³ when the radius is 3 cm.

mark amount = 80% of $125

=80/100 *125

=10000/100

=$100

final price = $125 + $100

=$225
