Recall that the complex norm (or modulus) of a complex number z = a + bi is defined as the nonnegative square root of the product of the complex number and its conjugate, i.e., |z| = √(z × z*), where z* is the complex conjugate of z.

Using this definition, we can calculate the complex norm of each of the given complex numbers as follows:

A complex number is a number that can be expressed in the form [tex]a + bi[/tex], where a and b are real numbers, and i is the imaginary unit defined by [tex]i^{2} = -1[/tex]. The real part of the complex number is a, and the imaginary part is bi.

Complex numbers can be added, subtracted, multiplied, and divided in a manner similar to real numbers. They can also be graphed on a complex plane, where the horizontal axis represents the real part and the vertical axis represents the imaginary part.

The number of ways 3 man and 3 woman line up at the counter in a store is 720 ways.

Factorials is defined as the mathematical expression that is the product of the given number down to 1. It is denoted with the symbol n! which means that is n is given as 4, then it's factorial would be = 4×3×2×1 = 24.

Given that, three men and three women line up at a checkout counter in a store.

a) Number of ways = 6!

= 6×5×4×3×2×1

= 720 ways

b) The first person in line is a woman, and then the line alternates by gender that is a woman, a man, a woman, a man, a woman, a man, and so on

There are 3 number of ways for woman standing in the odd position and for men standing in the even position.

So, number of ways = 3!×3!

= 3×2×1×3×2×1

= 36 ways

c) There are 3 men and 3 women.

Probability first is a woman is 3/6

Probability second is a man is 3/5

Probability third is a woman is 2/4

Probability fourth is a man is 2/3

Probability fifth is a woman is 1/2

Probability sixth is a man is 1/1

Multiply all these probabilities together and you get:

3/6 × 3/5 × 2/4 × 2/3 × 1/2 × 1/1 = 0.05

Therefore, the number of ways 3 man and 3 woman line up if the first person in line is a woman, and then the line alternates by gender that is a woman is 36 ways.

the probability of picking a defective missile with the first pull is

5/22

the probability of picking a working missile with the first pull is

17/22 = ((22-5)/22)

I have to assume that the picked missiles are not put back into the main pile after the check.

and I have to assume that the sequence of the pulled missiles don't matter.

a.

all are defective.

since there are only 5 defective missiles, there is only one possibility out of all the possibilities to pull 5 out of 22 to get 5 defective missiles.

the possible combinations to pull 5 out of 22 :

C(22, 5) = 22! / ((22 - 5)! × 5!) =

= 22×21×20×19×18×17/(5×4×3×2) =

= 22×21×19×3×17 = 447,678

and we have one desired situation (all 5 are defective).

so, the probability is

1/447678 = 0.000002233748364... = 2.233748364e-006

b.

all 5 are functional.

the total possible cases to pull 5 out of 22 are still

447,678.

the desired cases are all cases to pull 5 out of the 17 (22 - 5) functional missiles.

that is

C(17, 5) = 17! / ((17 - 5)! × 5!) =

= 17×16×15×14×13 / (5×4×3×2) =

= 17×2×14×13 = 6,188

so, the probability to get one of these cases is

6188 / 447678 = 0.013822435...

The probability of picking a defective missile with the first pull is 5/22

The probability of picking a working missile with the first pull is 17/22

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

If we assume that the picked missiles are without replacements and the sequence of the pulled missiles don't matter,

Therefore, the probability that:

a. all are defective is 2.233748364e-006

Since there are only 5 defective missiles, there is only one way to get 5 defective missiles out of 22 possible outcomes.

The possible combinations to pull 5 out of 22 :

C(22, 5) = 22! / ((22 - 5)! × 5!) =

= 22×21×20×19×18×17/(5×4×3×2) =

= 22×21×19×3×17 = 447,678

and we have one desired situation (all 5 are defective).

so, the probability is 1/447678 = 0.000002233748364... = 2.233748364e-006

b. all 5 are functional is 0.013822435

the total possible cases to pull 5 out of 22 are still 447,678.

The ideal scenario is for all incidents to result in the removal of 5 of the 17 (22 - 5) operational missiles.

that is

C(17, 5) = 17! / ((17 - 5)! × 5!) =

= 17×16×15×14×13 / (5×4×3×2) =

= 17×2×14×13 = 6,188

Answer:

  b = 30

Step-by-step explanation:

You want the value of b given line y = 20x +b passes through the points (6, 150) and (11, 250).

The equation y = 20x +b can be solved for b:

  b = y -20x . . . . . . . . subtract 20x

Using the given point (x, y) = (6, 150), you have ...

  b = 150 -20(6) = 150 -120

  b = 30

The requried teacher needs $59.5 more to buy cups and napkins, as of the given condition.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
To find out how much more money the teachers will need to buy cups and napkins, we can first calculate the cost of each item and then add those costs together.

Each package of cups costs $3.50

The teachers need to buy 12 cups

So the total cost of cups is = 12 cups × ($3.50 per package) = $42

Now let's do the same thing for the napkins:

Each package of napkins costs $4.25

The teachers need to buy 10 napkins

So the total cost of napkins is = 10 napkins × ($4.25 per package) = $42.50

To find out how much more money the teachers will need to buy cups and napkins,

= $42 + $42.50 - $25
= $59.50 - $25 = $59.5

Therefore, the teachers will need $59.5 more to buy cups and napkins.

The points M(0, -1), and T(4, 6), on the diagonal [tex]\overline{MT}[/tex] of the rhombus MATH, indicates that the equation of the line containing the diagonal [tex]\overline{AH}[/tex], in slope and intercept form is; [tex]y = 3\frac{9}{14} - 4\cdot \frac{x}{7}[/tex]

A rhombus is a quadrilateral that has four congruent sides.

The specified shape of the quadrilateral MATH = A rhombus

The coordinates of the endpoints of the diagonal [tex]\overline{MT}[/tex] of the rhombus are;

The equation of the line that contains the diagonal [tex]\overline{AH}[/tex] of the rhombus can be found as follows;

The diagonals of a rhombus are perpendicular, therefore, the slope of the diagonal, [tex]\overline{AH}[/tex]is -1 divided by the slope of the diagonal [tex]\overline{MT}[/tex]

The slope of [tex]\overline{MT}[/tex] = (6 - (-1))/(4 - 0) = 7/4

The slope of [tex]\overline{AH}[/tex] = -1/(7/4) = -4/7

The diagonals of a rhombus bisect each other, therefore, the diagonals [tex]\overline{MT}[/tex] and [tex]\overline{AH}[/tex] intersect at the midpoint of point [tex]\overline{MT}[/tex]

Therefore, the midpoint of [tex]\overline{MT}[/tex] is a point on the diagonal line that contains the diagonal [tex]\overline{AH}[/tex]

The midpoint of [tex]\overline{MT}[/tex] = ((0 + 4)/2, (-1 + 6)/2) = (2, 2.5)

The equation of the line containing the diagonal [tex]\overline{AH}[/tex] is therefore;

y - 2.5 = (-4/7)·(x - 2)

y = -4·x/7 + 8/7 + 2.5 = -4·x/7 + 51/14

y = -4·x/7 + 51/14 = -4·x/7 + 3 9/14

Where x represents the number of keychains sold and y represents the number of t-shirts sold.

Answer:

h(x) = 0.5x + 8

Step-by-step explanation:

We are being asked to write an equation where h(x) represents the soil depth in inches and x describes the number of bags. To do this, we need to find b (our y-intercept, ie the value of h(x) or y when x=0) and m (our slope).

"The depth of the soil is currently 8 inches": this means before any bags are added (ie when x=0), the soil depth starts at 8. This makes 8 our y-intercept (b in h(x)=mx+b) as we have to add it on to however much the bagged soil adds in order to get the total depth.

"For each bag of soil he adds, the depth will increase by 1/2 of an inch": this means that the soil depth from added bags is equal to the amount of bags times 0.5, which makes 0.5 our slope (m in h(x)=mx+b).

Therefore our answer is:

h(x) = 0.5x + 8

The equation of line is y = 1.5x + 5.5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

We have the reference point as (-2, 2.5) and (-1, 4)

so, slope

= (4- 2.5)/ (-1 + 2)

= 1.5

and, the equation of line is

y- 2.5 = 1.5 (x+ 2)

y- 2.5 = 1.5x + 3
