Answer:

There are 21 observations in the data set, which is an odd number. Therefore, the middle value will be the (n+1)/2th observation, where n is the total number of observations.

The middle value = (21+1)/2 = 11th observation

The 11th observation is 4,291, so the median of the data is $4.291 million dollars.

As a car dealer lowers a vehicle that was worth 18300 to 16000 by applying the formula of change in percentage we get that by 12.569 percentage (approximately) the price gets lowered .

The initial price of the car is set at P = 18300 (units)

The price after lowering drom P becomes A= 16000 (units)

Hence the change in price (or value) of the car, that is the price of the car is lowered by, C = (initial price - lowered price) = (P - A) = (18300 - 16000) units = 2300 units.

The formula for calculating percentage change is given as follows,

Change in percentage = [(Change in value)/ ( Initial value) ]*100

⇒Change in percentage = (C/ P)*100

⇒ Change in percentage =( 2300/ 18300)*100 = 12.569% (approximately)

Answer:

So 61.5 inches I'm guessing in feet would be 5.125 feet. You just divide 61.5 by 12 to get your answer.

Step-by-step explanation:

Answer: i would say the answer is 90 degrees

Step-by-step explanation:

Answer:

x<=-4 or -2<=x<=2 or x>=4

Step-by-step explanation:

First, you have to get the formula in its standard form,

x^4 - 18x^2 + 64 >= 0

Next, you factorise the expression as you would any trinomial. The fact that the degree of the inequality is 4 instead of 2 just adds an extra step,

(x^2 - 16)(x^2 - 4) >= 0

Get the zeroes/critical values of the equation by equating either bracket to zero.

x^2 - 16 = 0  and  x^2 - 4 = 0

x^2 = 16                x^2 = 4

Since both values are positive, both answers are valid as squares of x. The aforementioned extra step is just square rooting these values. Remember: This means that both a positive and negative answer will arise from both equations.

x = 4 or x = -4 or x = 2 or x = -2

Now you have to show these values on a number line.

 -4     -2       2       4

_|____|____|____|_

These are the critical values of the inequality, i.e. those values that make it equal zero (zeroes). Now to solve the inequality you need to substitute a value larger than 4 (called x big positive) and then a value between 2 and 4, between -2 and 2... until you sub a value less than -4 into the factorised expression. The point of this is to get the SIGN of the answer. As a rule, since no factors repeat themselves, after calculating x big positive you can simply alternate the signs going left. Try it out yourself!

+ -4 -  -2  +   2   -   4  +

_|____|____|____|_

Since we're looking for values greater than or equal to zero, all critical values as well as "plus signs" will form part of the answer, namely:

x<=-4 or -2<=x<=2 or x>=4

P.S. If you prefer, you could also factorise each bracket further as both of them were DOTS brackets and you would have ended up with the same critical values.

Answer: D

Step-by-step explanation:

The individual values contained in an array are known as elements.

An array is a data structure that allows you to store multiple values of the same data type in a single variable. Each value within the array is assigned a unique index or position, starting from 0 for the first element. These elements can be accessed and manipulated using their respective indices.

By organizing related data into an array, it becomes easier to perform operations on the entire set of values or access specific elements based on their positions. Elements in an array can be of any data type, such as numbers, characters, or objects, depending on the programming language used.

The linear transformation illustrate that:

a. There are infinite solutions.

b. 1

c. 2

d. 3

Since A is the matrix of the linear transformation T, hence ker(T) = ker(A), nullity (T) = nullity(A), range(T) = col(A) and rank(T) = rank(A).

(a) ker(T) = ker(A) is the set of solutions to the equation T(X) = AX = 0. To solve this equation, we will reduce A to its RREF as under:

Interchange the 1st row and the 2nd row

Multiply the 1st row by 1/12

Multiply the 2nd row by -1/6

Then the RREF of A is

1   0    19/12

0    1    -7/6

Now, if X = (x,y,z)T, then the equation T(X) = AX = 0 is equivalent to x +19z/12= 0 or, x = -19z/12 and y-7z/6 = 0 or, y = 7z/6 so that X = (-19z/12,7z/6,z)T = (z/12)(-19,14,12)T.

Thus, ker(T) = {t(-19,14,12)T} where t is an arbitrary real number. There are infinite solutions.

(b). Since the RREF of A has 2 non-zero rows, hence rank(A) = 2. As per the rank-nullity theorem, nullity(T) = nullity(A) = No. of columns in A, -rank(A) = 3-2= 1.

( c). The first 2 columns of A are linearly independent and its 3rd column is a linear combination of its first 2 columns.

Hence, range(T) = col(A) = span{(0,12)T,(-6,0)T} = R2 ( as the vectors (0,12)T,(-6,0)T are scalar multiples of (0,1)T,(1,0)T respectively and the vectors (0,1)T,(1,0)T constitute the standard basis of R2.

(d). As in (b) above, rank(T) = rank(A) = 2.

2.8 and 4.4

Step-by-step explanation:

The distance between tick marks is 0.25.

Since the first number is greater than 2.75, we can approximate is as 2.28.

The second number is less than 4.50, we can approximate it as 4.4.

The inequality that represents the situation is 8.50x < 35 and the pounds of shrimp Luna can buy is 4.

Inequality is a statement that two or more mathematical expressions are unequal.

Inequalities are represented as greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), and not equal to (≠).

The cost price of shrimp per pound = $8.50

The total spending budget = $35

Let the number of pounds of shrimp Luna can buy = x

8.50x < 35

x = 4

Thus, the total amount Luna can spend on shrimp is $34 (4 x $8.50), which is less than $35.

Decomposed relations  are i. R = R1 ∪ R2 ∪ R3, where R1 = (ABC), R2 = (BD), and R3 = (CA) , ii. R = R1 ∪ R2 ∪ R3 ∪ R4 ∪ R5, where R1 = (ABCE), R2 = (ACD), R3 = (BEDC), R4 = (CD), and R5 = (EAB).

To decompose the given relations into Boyce-Codd Normal Form (BCNF), we need to analyze the functional dependencies and ensure that each functional dependency is fully satisfied.

i. R = (ABCD), F = {AB→C, B→D, C→A}

We observe that the functional dependencies in F are:

1. AB→C

2. B→D

3. C→A

To achieve BCNF, we need to decompose R based on these dependencies. Let's analyze each dependency:

1. AB→C: Since AB is a candidate key (a minimal superkey), we create a new relation, R1 = (ABC), and remove AB→C from F.

2. B→D: As B is not a candidate key, we create another relation, R2 = (BD), and remove B→D from F.

3. C→A: C is not a candidate key, so we create a third relation, R3 = (CA), and remove C→A from F.

The final decomposition is R = R1 ∪ R2 ∪ R3, where R1 = (ABC), R2 = (BD), and R3 = (CA). All functional dependencies are now fully satisfied in BCNF.

ii. R = (A, B, C, D, E), F = {AB→CE, AC→D, BE→CD, C→D, E→AB}

We analyze the functional dependencies in F:

1. AB→CE

2. AC→D

3. BE→CD

4. C→D

5. E→AB

To achieve BCNF, we decompose R based on these dependencies:

1. AB→CE: We create a new relation, R1 = (ABCE), and remove AB→CE from F.

2. AC→D: We create R2 = (ACD), and remove AC→D from F.

3. BE→CD: We create R3 = (BEDC), and remove BE→CD from F.

4. C→D: We create R4 = (CD), and remove C→D from F.

5. E→AB: We create R5 = (EAB), and remove E→AB from F.

The final decomposition is R = R1 ∪ R2 ∪ R3 ∪ R4 ∪ R5, where R1 = (ABCE), R2 = (ACD), R3 = (BEDC), R4 = (CD), and R5 = (EAB). All functional dependencies are now fully satisfied in BCNF.

The graph of the inequalities x < -8 and x ≥ 3 would be the lines right to 3 in the number line which also includes 3 and the line left to -8 but -8 not included.

Number lines are the graphical representation of numbers on a horizontal straight line where the numbers are placed on equal intervals. We can graph the equations and inequalities of one variable on a number line.

The given inequalities are x < -8 and x ≥ 3.

First let us consider the inequality x < -8.

This means that all the numbers which is less than -8 but does not include -8.

That will be a line tends to left from -8 with an open circle on -8.

Consider the other inequality x ≥ 3.

This includes all the numbers which are greater than 3 and also include the number 3 since the inequality is ≥.

The graph will be a line tends to right from 3 with a closed circle on 3.

Hence the graph of this compound inequality will be a line tends to left with an open circle on -8 and a line tends to right with a closed circle on 3.
