Answers
Answer:
Step-by-step explanation:
Answer:
(6 ± 3i)/5
Step-by-step explanation:
12x = 9 + 5x²
5x² - 12x + 9 = 0
Method 1
Factors that add to = b (-12) and multiply to = ac (45): 3 and -15
5x² + 3x - 15x + 9 = 0
5x(x - 3) + 3(x + 3) = 0
(x-3) and (x+3) do not match !!!!
Method 2 - Quadratic Formula
-b ± √(b² - 4ac)/2a
12 ± √((-12)² - 4(5)(9))/2(5)
12 ± √((-12)² - 4(5)(9))/2(5)
12 ± √(144 - 180)/10
12 ± √-36/10
(12 ± 6i)/10

The linear function is given by table B and the equation y = ( 1/2 )x + 3.2
What are Linear Equations?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution
On a graph, a linear equation forms a straight line. On a graph, a nonlinear equation produces an S-curve, a bell curve, or another nonlinear shape.
Given data ,
Let the linear function be represented as A
Now , the value of A is
Let the x values be x = { 0 , 2 , 4 , 6 , 8 }
Let the y values be y = { 3.2 , 4.2 , 5.2 , 6.2 , 7.2 }
Now , the equation of line is y - y₁ = m ( x - x₁ )
where m is the slope
m = ( 4.2 - 3.2 ) / ( 2 - 0 )
m = 1/2
On simplifying , we get
y - 3.2 = ( 1/2 ) ( x - 0 )
Adding 3.2 on both sides , we get
y = ( 1/2 )x + 3.2
Hence , the linear function is y = ( 1/2 )x + 3.2

Answers
Answer:
Step-by-step explanation:
Here, I will instead go through the process for finding the probability of choosing two girls. Then once you understand how it was done, hopefully you will be able to answer the actual question for yourself.
Finding the probability of choosing two girls. Let's make it simpler by starting with the probability of choosing the first girl only.Probability of choosing the first girl. (Note: the letter chosen to represent the event is not important. Pick something that makes sense to you and be consistent)
P(G1) = # of girls / # of total outcomesSo the number of girls we know to be 11. What is the number of total outcomes? Well a boy or a girl can be chosen, and there are 14 boys and 11 girls, for a total of 25 students.
P(G1) = 11/ 25Let's find the probability of choosing the second girl from here.
P(G2) = # of girls / # of total outcomesHowever, this time things have changed. We've already chosen one girl, so the number of girls remaining to choose from is reduced 11 to 10. And the total number of students to choose from is reduced from 25 to 24.
P(G2) = 10 / 24Now we have the probability of choosing the first girl and the probability of choosing the second girl. From here, we just need to combine them to find the probability of both things happening together. To calculate the probability of two different events occurring, you multiply the two probabilities together.
Probability of choosing two girls. Let's use T for Two girls.
P(T) = P(G1) × P(G2) = (11 /25) × (10/24)
From here you can use a calculator to find the answer. This answer can either be written as a fraction, a decimal, or a percentage.
= 0.19 = 19 / 100 = 19%

hypotenuse = 2xline opposite of 30° = xline opposite of 60° = x√3With that being said....
c = 2x
6 = x
a = x√3
We know that x = 6, so now solve for a & c:

about
Answers
The market share of the companies is an illustration of fractions.
The market share of each company in the long run (i.e. after 6 months) is 37/108, 35/216 and 1/108, respectively
How to determine the market shares in the long runThe current market shares are:
Company A = 2/9Company B = 4/9Company C = 1/3After 6 months, we have:
Company A:
Retains 3/4Losses 1/6 to BLosses 1/12 to CCompany B:
Retains 1/2Losses 1/3 to ALosses 1/6 to CCompany C:
Retains 3/8Losses 1/4 to ALosses 3/8 to BThe amount of customers lost by each company is
Lost = Market share * [Share retained - Share lost to the other two companies].
So, we have:
A = 2/9 * [3/4 - 1/6 - 1/12] = 1/9
B = 4/9 * [1/2 - 1/3 - 1/6] = 0
C = 1/3 * [3/8 - 1/4 - 3/8] = -1/12
The amount of customers gained by each company is
Gain = Market share of company gained from * Share gained
So, we have:
A = 1/3 * 4/9 + 1/4 * 1/3 = 25/108
B = 1/6 * 2/9 + 3/8 * 1/3 = 35/216
C = 1/12 * 2/9 + 1/6 * 4/9 = 5/54
The total gain in 6 months is:
Total Gain = Gain + Loss.
This gives
A = 25/108 + 1/9 = 37/108
B = 35/216 + 0 = 35/216
C = 5/54 - 1/12 = 1/108
Hence, the market share of each company in the long run (i.e. after 6 months) is 37/108, 35/216 and 1/108, respectively

Move 4.2 to the other side as a negative
10.8=0.3x
