L 2. (a) Which term of the arithmetic progression 8 - 6i, 7 – 4i, 6 — 2i, ... is purely imaginary [3]

Answers

Answer:

10i

Step-by-step explanation:

8-7=1

7-6=1

The real part of the complex numbers is following an arithmetic progression with first term 8 and common difference 1.

………………………………………

-6+2=-4

-4+2=-2

THe Imaginary part of the complex numbers is following an arithmetic progression with first term -6 and common difference 2.

………………………………………

Then the term she of the sequence can be written:

(8 - n) + i(-6 + 2n)

………………………………………

We get a purely imaginary term when its real part is nul :

⇒ 8 - n = 0

⇒ 8 = n

………………………………………

If we take n = 8

⇒ -6 + 2n = -6 + 2×8 = -6 + 16 = 10

Therefore,

The term of the arithmetic progression 8 - 6i, 7 – 4i, 6 — 2i, ... which is purely imaginary is :

10i

The fraction with the greatest value is 5/6

How to determine the greatest fraction?

Fractions are numbers that are represented by the quotients of two integers.

The fractions are given as:

1/6, 5/6, -1/6 and -5/6

Negative numbers are less than positive numbers.

So, the remaining fractions are:

1/6 and 5/6

Both fractions have the same denominator.

So, we consider the numerator

5 is greater than 1

Hence, the fraction with the greatest value is 5/6

Answers

Answer:

1/36.

Step-by-step explanation:

We have a probability of 1/6 that the first die rolls 2, and a probability of 1/6 that the second die rolls 2, thus making a combination (2,2) with the probability 1/36.

Answers

Answer:

Logistic growth is like growth statistics only known when the population size is affected by limited resources. Logistic growth is a mix of math and science, and comes helpful for studying populations.

One example of logistic growth formula is f(P) = rP(1 - P / K)

Where K is your relative growth rate co-efficient(only when K is lowercased. Otherwise, K is carrying capacity.)

And P is your initial population.

The weights of four year old boys are normally distributed with a mean of 38 pounds and a standard deviation of 4 pounds. Which of the following weights could represent the 90tn percentile for the weight of a four year old?

Answers

The weights that represent 90% of the weight of a four years old boy will be 44.58

What is a z-score?

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The weights of four years old boys are normally distributed with a mean of 38 pounds and a standard deviation of 4 pounds.

The value of the z-score at 90% will be 1.645

Then the weights that represent the 90% of the weight of a four year old will be

1.645 = (x - 38)/4

6.58 = x - 38

x = 44.58

Find the sum of the first 21 terms of the arithmetic series.
46 +53 +60 +67+ ...

Answers

Answer:

2436

Step-by-step explanation:

The sum of n terms of an arithmetic series is given by the formula ...

Sn = (n/2)(2a +d(n -1))

where a is the first term, and d is the common difference.

This series has ...

a = 46

d = 53 -46 = 7

n = 21

So, the desired sum is ...

S21 = (21/2)(2(46) +7(20)) = 2436

The sum of the first 21 terms is 2436.

simplify6(x - 3) = -42.

Answers

Answer:

x = -4

Step-by-step explanation:

First Expand :

6(x - 3)

= 6x - 18

Now you need to Simplify:

6x - 18 = -42

And now get the 6x by itself by doing this :

6x - 18 = -42

+18 +18

= > 6x = -24

And 6 x 4 = 24

But 6 x -4 = -24

So :

6x/6 and -24/6

Line segment GH has endpoint G(10,11) and H(−2, −7).

Part A: The point Z lies on segment GH and is located at (6, 5). What is the ratio of GZ: ZH?

Part B: Find the coordinates of Q such that HQ: GH = 1: 6.

Answers

PART A:

Answer:

(-1,-2)

Step-by-step explanation:

The given coordinates are ,

G ( 4 , 10)

H ( -2 , -6)

Midpoint can be calculated by finding the mean of x coordinates and y coordinates . As ,

→ Midpoint = ( 4-2/2 , 10-6/2)

→ Midpoint = ( -2/2 , -4/2 )

→ Midpoint = ( - 1 , -2)

Hence the midpoint is (-1,-2)

PART B:

To find out the midpoint,here's the formula: ((x1+x2)÷2 , (y1+y2)÷2)

Thus,the midpoint of QS is

((4+(-2))÷2 , (10+3)÷2)

=(1 , 13/2)
