An investor owns a bond. Suppose there is a 20% probability the investor will lose $100 on the bond and an 80% probability the investor will gain $30 on the bond. Find the expected value (expected return) of the bond. Enter the number only. Do not include the $ sign.
======================================================
Work Shown:
A = event of losing $100
P(A) = probability event A occurs = 0.20
V(A) = net gain of event A happening = -100
B = event of gaining $30
P(B) = probability event B occurs = 0.80
V(B) = net gain of event B happening = 30
-----------------
E(X) = expected value
E(X) = P(A)*V(A) + P(B)*V(B)
E(X) = 0.20*(-100) + 0.80*(30)
E(X) = 4
The expected value is $4
This means the investor expects to get an average return of $4.

Is this a proportional relationship?
A runner runs 6 miles per hour for 3 hours
Proportional
Non-proportional
Answer:
ProportionalStep-by-step explanation:
Step one:
given data
We have a question to answer
given that the speed is 6 mph and the time taken is 3 hours
v= 6mph, t= 3, distance =?
distance= speed * time
distance= 6*3= 18miles
From the distance calculated, we can see that there exist a proportional relationship, lets say the time taken is 4 hours, then the distance will be
distance= 6*4= 24 miles.
hence the distance traveled is proportional to the time taken

Answer:
Option A
a + s = 1650 ; 3.5a + 2b = 4580
Step-by-step explanation:
a ------> number of adult tickets
s ------> number of student tickets
Total tickets = $ 1650
a +s = 1650
Cost of 'a' number of adult tickets = 3.50*a = 3.5a
Cost of 's' number of student tickets = 2*s = 2b
Revenue raise = $ 4580
3.5a + 2b = 4580
9. Chocolate Co. mixes two kinds of chocolate bars

Please show work

Answer:
1 pound of expensive chocolate2 pounds of other chocolateStep-by-step explanation:
Let e represent the number of pounds of expensive chocolate in the bag. Then (3-e) is the amount of the other chocolate. The total cost of the bag will be ...
6.00e +4.50(3 -e) = 15.00
1.50e = 1.50 . . . . . . collect terms, subtract 13.50
e = 1 . . . . . . . . . . . . .divide by 1.50
1 pound of expensive chocolate is used; 2 pounds of other chocolate is used.

factor the following expression[x squared minus x minus 12]
x2-x-12
Answer:
[tex]x^2-x-12=(x-4)(x+3)[/tex]
Step-by-step explanation:
Factoring a Trinomial
A trinomial is expressed in the form
[tex]ax^2+bx+c[/tex]
Where a,b, and c are real constants.
Some trinomials can be factored as the product of binomials with real coefficients, while others cannot.
If possible, factoring can be done in several ways:
Factoring out the GCF. The sum-product pattern (by inspection).The grouping method. The perfect square trinomial pattern. The difference of squares pattern.Knowing the rootsEach method is most likely applicable under certain circumstances. When the polynomial has a leading coefficient of a=1, the sum-product pattern is the fastest and easiest option.
We have the polynomial
[tex]x^2-x-12[/tex]
Here: a=1, b=-1, c=-12
The sum-product method needs us to find two numbers which sum is -1 and product is -12. Those numbers can be found by inspection by combining two divisors of 12, say 1 and 12, 2 and 6, or 3 and 4.
Only one of those pairs can be combined to produce a sum or subtraction equal to -1: Those numbers are -4 and 3. Thus the factorization is:
[tex]\mathbf{x^2-x-12=(x-4)(x+3)}[/tex]
The average score of this quiz is 24 points with a standard deviation of 1.5 points. What is the probability that someone scored 21.9 or less
Answer:
8.08 %
Step-by-step explanation:
Let us denote : [tex]X=[/tex] score X follows a normal distribution with mean [tex]=24[/tex] and standard deviation [tex]=1.5[/tex]
Step 2
The probability that someone scored 21.9 or less is :
[tex]\mathrm{P}(\mathrm{X} \leq 21.9)[/tex]
[tex]=\mathrm{P}\left(\mathrm{Z} \leq \frac{21.9-24}{1.5}\right)[/tex]
[tex]=\mathrm{P}(\mathrm{Z} \leq-1.4)[/tex]
[tex]=0.0808[/tex]

A rectangular prism has a length of 4/5 inch and a width of 1/3 inch the volume of the prism is 32/45 cubic inch find the height of the prism
Answer:
2 and 2/3 inches
Step-by-step explanation:
v = l x w x h
[tex]\frac{32}{45}[/tex] = [tex]\frac{4}{5}[/tex] · [tex]\frac{1}{3}[/tex] · h
[tex]\frac{32}{45}[/tex] = [tex]\frac{4}{15}[/tex] h
cross-multiply to get 45 x 4 x h = 32 x 15
180h = 480

Answer:
No values of x- Any whole number that is not 8
All values of x: 8
Just one Value of x: There could be many possibilites but all of them have to be some value of x. One answer is:x
Step-by-step explanation:
3x + 8 = 3x + x, which has one solution at x=8.
The given equation is 3x+8=3x+ ____.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
If 3x + 8 = 3x + 7 has no solutions
If 3x + 8 = 3x + 8 has infinite solutions
If 3x + 8 = 3x + x is equal to 3x + 8 = 4x, which has one solution at x=8
Therefore, 3x + 8 = 3x + x, which has one solution at x=8.
