Combine like terms
5x - 45 = 180
Add 45 to both sides
5x = 225
Divide both sides by 5

Jean wants to invest a gift of $4,250 in the stock market. A broker suggests two companies, Solar Solutions (SOLR) and Frontline Medical (FLMD). He provides the probabilities for an annual return on $4,250 based on their historical gains: SOLR: 50% chance of $1,000 gain, 35% chance of $200 gain, 15% chance of $600 loss FLMD: 80% chance of $750 gain, 20% chance of $100 loss Which is the best analysis of these investments?
Answers
Answer:
the answer is the question with $580 in it please correct me if im wrong
Step-by-step explanation:
Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.
How to calculate the expected return?The expected return on SOLR is calculated by multiplying the probability of each outcome by the amount of the gain or loss, and then adding these results:
50% chance of $1,000 gain: 0.5 x $1,000 = $500
35% chance of $200 gain: 0.35 x $200 = $70
15% chance of $600 loss: 0.15 x -$600 = -$90
Therefore, the expected return on SOLR is $500 + $70 - $90 = $480.
The expected return on FLMD is calculated in the same way:
80% chance of $750 gain: 0.8 x $750 = $600
20% chance of $100 loss: 0.2 x -$100 = -$20
Therefore, the expected return on FLMD is $600 - $20 = $580.
Since the expected return on FLMD is higher than the expected return on SOLR, FLMD is the better investment.
The expected return on FLMD is $580, which means that Jean can expect to earn about $580 on her investment of $4,250 if she invests in FLMD.

In a class of students, the following data table summarizes how many students have a cat or a dog. What is the probability that a student has a cat given that they do not have a dog? ( NO LINKS )
Answers
Given:
Number of students who has a cat and a dog = 5
Number of students who has a cat but do not have a dog = 11
Number of students who has a dog but do not have a cat = 3
Number of students who neither have a cat nor a dog = 2
To find:
The probability that a student has a cat given that they do not have a dog.
Solution:
Let the following events:
A = Student has a cat
B = Do not have a dog
Total number of outcomes is:
[tex]5+3+11+2=21[/tex]
The probability that a student has a cat but do not have a dog is:
[tex]P(A\cap B)=\dfrac{11}{21}[/tex]
The probability that a student do not have a dog is:
[tex]P(B)=\dfrac{11+2}{21}[/tex]
[tex]P(B)=\dfrac{13}{21}[/tex]
The conditional probability is:
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{P(A\cap B)}{P(B)}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{\dfrac{11}{21}}{\dfrac{13}{21}}[/tex]
[tex]P\left(\dfrac{A}{B}\right)=\dfrac{11}{13}[/tex]
Therefore, the probability that a student has a cat given that they do not have a dog is [tex]\dfrac{11}{13}[/tex].

The diameter of a truck wheel is 56.5 inches. What is the circumference of
the wheel?
Answers
Answer: 177.4999849 , or 56.5pi
Step-by-step explanation:
You simply divide the diameter by 2 to get the radius (28.25) and then plug into the circumference equation, 2*pi*r = Circumfrence.
Answer:
177.5 inches
Step-by-step explanation:
c = 2πr
d = r2
56.5/2=28.25
28.25x3.14= 88.705
88.705x2=177.41
Round, and you’ll get 177.5.
f(x) = x°-9x
g(x) = x2 - 2x-3
Which of the following expressions is equivalent to f(x)/g(x), for x > 3
Answers
and
g(x)=x^2-2x-3
so you just need to divide f(x) by g(x)
Therefore:
f(x)/g(x) = (x^3-9x) / (x^2-2x-3)
and of course you need to factor these two function to see if some factor would cancel another
x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
