6 - 6/2 - 6 = 0/-4 = 0

Step-by-step explanation:

The probability that the student chosen at random was male OR got an "A" is 31/58.

To find the probability that the student was male OR got an "A," we need to calculate the probability of each event separately and then add them together.

Let's calculate the probability of the student being male:

Total number of males = 11

Total number of students = 58

Probability of the student being male = Number of males / Total number of students = 11/58

Now, let's calculate the probability of the student getting an "A":

Total number of students who got an "A" = 20

Probability of the student getting an "A" = Number of students who got an "A" / Total number of students = 20/58

To find the probability of the student being male OR getting an "A," we add the two probabilities together:

Probability (Male OR A) = Probability (Male) + Probability (A) = 11/58 + 20/58 = 31/58

Therefore, the probability that the student chosen at random was male OR got an "A" is 31/58.

Answer:

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

A matrix is in row echelon form if it satisfies the following three conditions:

(i). All non-zero rows are above any zero rows.

(ii). Each leading entry in a row is in a column to the right of the leading entry of the row above it.

(iii). All the entries in a column below a leading entry are zeros.

The following operations on a matrix are called elementary row-operations:

1. Interchanging the ith and the jth rows, expressed as ri <--> rj.

2. Replacing the ith row by a multiple of itself expressed as ri --> krj, where k is a non-zero scalar.

3. Replacing the jth row by the sum of itself and a non-zero multiple of the ith row, expressed as rj --> rj + kr.

It may be observed that all the 3 elementary row-operations are reversible. Thus. ri <--> rj can be reversed by ri <--> rj,  ri --> kri can be reversed by ri -->(l/k)*ri, (here ri indicates the new ith row) and  rj --> rj + kr can be reversed by rj --> rj - krj.

Now, since both the matrices A and B are reduced to the same RREF C (say), hence reversing the elementary operations used to reduce B to C, we get B from C. Thus, A can first be converted to C and then to B.

The correct answer is 3/2. In this case, x = 3/2, and its square, (3/2)^2 = 9/4, is rational. x satisfies the given condition.option (c)

To explain further, we need to understand the properties of rational and irrational numbers.

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a fraction and has non-repeating, non-terminating decimal representations.

In the given options, (a) √5102.0 (£) and (b) √2 are both irrational numbers.

Their squares, (√5102.0)^2 and (√2)^2, would also be irrational, violating the given condition. On the other hand, (d) 4/5 is rational, and its square, (4/5)^2 = 16/25, is also rational.

Option (c) 3/2 is rational since it can be expressed as a fraction. Its square, (3/2)^2 = 9/4, is rational as well.

Therefore, (c) 3/2 is the only option where x is rational, but its square is irrational, satisfying the condition mentioned in the question.

In summary, the number x that satisfies the given condition, where x^2 is irrational but x is rational, is (c) 3/2.option (c)

Answer:

Let d represent the distance from home to school

To find d we use the formula for Pythagoras theorem

That's

a² = b² + c²

Where a is the hypotenuse or the longest side

From the question

d is the hypotenuse

So we have

d² = 4² + 5²

d² = 16 + 25

Answer:

Sample mean = 6

Sample standard deviation = 3

Range = 3 to 9

Step-by-step explanation:

Given data:

Rankings (x)

9

6

1

7

7

sample size = n = 5

(a)

Sample Mean: \(\frac{}{x}\) = ∑x/n

                            = 9+6+1+7+7 / 5

                            = 30 / 5

                    \(\frac{}{x}\)      = 6

Sample Standard Deviation = s = √(x- \(\frac{}{x}\) )²/n-1

= √((9-6)² + (6-6)² + (1-6)² + (7-6)² + (7-6)²) / (5-1)

= √((3)² + (0)² + (-5)² + (1)² + (1)²) / 4

= √(9+0+25+1+1)/4

= √36 / 4

= √9

= 3

s = 3

b) In what range does the empirical rule predict that approximately 68% of the class will rank you?

As per the empirical rule, 68% of data falls within first standard deviation  from the mean μ ± 1σ

\(\frac{}{x}\)  = 6

s = 3

So

6 - 3 = 3

6 + 3 = 9

Hence the range is from 3 to 9

If z = 1 + √3i, then z^6 equals 64.

In Mathematics, a complex number can be defined as any numerical quantity that comprises two main parts, which include a real number and an imaginary number.

Note: i² = -1.

In this exercise, you are required to determine the exponent of the given complex numbers as follows:

z = 1 + √3i

z^6 = (1 + √3i)^6

Where:

Next, we would apply binomial theorem;

Exponent = ∑^6 _i=0(^6_i) · 1^(6 - i)(√3i)^i

Exponent of 0 = 6!/0!(6 - 0)! · 1^0(√3i)^0 = 1

Exponent of 3 = 6!/3!(6 - 3)! · 1^3(√3i)^3 = 60(√3i)^3

Exponent of 6 = 6!/6!(6 - 6)! · 1^0(√3i)^6 = (27i)^6

b = 18

Step-by-step explanation:

1st step is isolating b by moving 2 to the other side. When you move a number the the other side it flips (from + to - or × to ÷). The 2 in this question is being multiplied my b (no sign means multiply) so when you move it to the other side it becomes 36/2 or 18

Steps:

2b=36

b=36/2

b=18

Answer:

b=18

Step-by-step explanation:

2b=36

Divide both sides by 2

b=36/2

then divide 36 by 2 to get 18

The value of the probability P (Sheep | Male) is 2/7

From the question, we have the following parameters that can be used in our computation:

Sheep = 4 and 3

Male = 1, 4, 2, 2 and 5

The probability P (Sheep | Male) is then calculated as

P(Sheep | Male) = (Sheep and Male)/Male

Substitute the known values in the above equation, so, we have the following representation

P(Sheep | Male) = 4/(1 + 4 + 2 + 2 + 5)

So, we have

P(Sheep | Male) = 4/14

Simplify

P(Sheep | Male) = 2/7

Hence, the probability is 2/7

The area of the shaded which is obtained using the composite figure formed the shaded region and the area under the curve of the specified function is; (2·π - 3·√3)/2 square units

A composite figure is one that is composed of two or more simpler figures.

The area can be considered of comprising of a composite figure of the area under the curve of the function and the area of the shaded region

The function representing the curve under the shaded region can be presented as follows;

y = 3·cos(x) + 1

The interval specified under the curve can be expressed as follows;

0 ≤ x ≤ π/3

Therefore, the area under the curve can be found as follows;

\(\int\limits^\frac{\pi}{3} _3 {3\cdot cos(x) + 1} \, dx = [3\cdot sin(x) + x]^{\frac{\pi}{3} }_0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3} - 0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3}\)

sin(π/3) = (√3)/2

Therefore; 3·sin(π/3) + π/3 = 3·(√3)/2 + π/3 = (2·π + 9·√3)/6

The area of the rectangle = (4 - 0) × (π/3 - 0) = 4·π/3

The area of the shaded region = Area of the rectangle - Area under the curve of the specified function

Therefore, area of the shaded region = 4·π/3 - (2·π + 9·√3)/6 = (2·π - 3·√3)/2

Answer:

#3  (3,1)

Step-by-step explanation:

#1.  (-3, 2) (0, y)  slope = -2

slope = rise/run    therefore slope = -2/1  or down 2 and over 1

so from -3 to 0 you are going over 3 units (or 3 times)  Therefore to find y at x=0, you have to move three steps, or 3 times -2 = -6      so 2-6 = -4

so y intercept (b)  = -4 0r (0,-4)

Answer:

14 necklaces

$98.56

Step-by-step explanation:

She made a total revenue of $223.86, and each necklace sold for $15.99, so the number of necklaces sold is:

$223.86 / $15.99 = 14

The profit is the sales price minus the cost of materials and labor, so the profit per necklace sold is:

$15.99 − ($3.38 + $5.57) = $7.04

She sold 14 necklaces, so her total profit is:

14 × $7.04 = $98.56

We will find the probability of getting each color of marble, and we will see that getting red and blue is equally likely, while getting green is less likely.

If we draw a marble at random from the box, all of them will have the same probability of being drawn.

Then the probability of getting a given color is given by the quotient between the number of marbles of that color and the total number of marbles.

Probability of getting red:

P = 11/25 =  0.44  This is really close to 50%, so this is equally likely.

Probability of getting blue:

P = 11/25 =  0.44  This is really close to 50%, so this is equally likely.

Probability of getting green:

P = 3/25 = 0.12 This is really close to 0%, so this is less likely.
