Answer:
Part A:
Probability that average single manager beat the index= [tex](0.5)^7=0.0078125=0.0078 (4\ decimals)[/tex]
Part B:
Fund Managers to beat index 7 years=78.125≅78 managers.
Step-by-step explanation:
Part A:
Given data:
Since there are equal chances for delivering equal better performance and of under performance so
Probability of better performance =0.5
Required:
Probability that the average single fund managers beats the index 7 years in a row (before fees)=?
Solution:
Since there is 7 year index:
Probability that average single manager beat the index= [tex](0.5)^7=0.0078125=0.0078 (4\ decimals)[/tex]
Part B:
Given Data:
Number of mutual fund managers=10,000
Probability that average single manager beat the index= 0.0078125 (Calculated in part A)
Required:
How many fund managers would you expect to beat the index 7 years in a row if only luck and no skill was involved?
Solution:
Fund Managers to beat index 7 years=Total number of managers*probability average single member beat the index
Fund Managers to beat index 7 years=10,000*0.0078125
Fund Managers to beat index 7 years=78.125≅78 managers.
What are the numerical measures of each angle
in the diagram?
<1and <3 measure
degrees
<2 and <4 measure
degrees.
(3x - 1)
1
3
2
(2x + 9)
Answer:
angle 1 and 3 are equal by vertically opp. angle
3x-1 = 2x +9
3x-2x = 9+1
x = 10
put the value of x in any equation
3(10)-1 = 29
angle 1 = angle 3 = 29
angle 2 + angle 3 = 180 ° (linear pair)
angle 2 = 180 -29
angle 2 = 149
angle = angle 3 = 149.

Answer: -5x^3 + 5y^3
Step-by-step explanation: The other parts cancelled out
Answer:
= -5x³ + 5y³
Step-by-step explanation:
4y³ - 5x³ - 1 - 4y³ - 6 + 7 + 5y³
= -5x³ + (4y³ - 4y³ + 5y³) + (- 1 - 6 + 7)
= -5x³ + (0 + 5y³) + (- 7 + 7)
= -5x³ + 5y³

4v2 - 25v = 21
Answer:
(4v + 3) and (v - 7)
Step-by-step explanation:
First rewrite 4v2 - 25v = 21 as 4v^2 - 25v - 21.
Let's now analyze -25v and -21. We need to identify two integers whose product is 21 and whose sum is -25.
Note that factors of -21 are ±1, ±3, ±7 and ±21. Factors of 4 (the coefficient of v^2) are ±1, ±2 and ±4.
Check out the following trial factors: (4v + 3) and (v - 7). Does this product come out to the given 4v^2 - 25v - 21? Yes. So the desired factors of 4v2 - 25v = 21 are (4v + 3) and (v - 7). Note how (3)(-7) = -21 and how 4(-7) + 3v add up to -25, the coefficient of the v term.

The 1-inch diameter pizza bite for $1 or the 10 inch diameter pizza for $10
Answer:
both same if we see. the one inch also costs l dollar wheras 10 dollar costs 10 inch. ok
Answer:
10in pizza
Step-by-step explanation:
We need to find the area of each pizza.
A = [tex]\pi[/tex][tex]r^{2}[/tex]
radius is 1/2 the diameter.
1in pizza 10in pizza
A = [tex]\pi[/tex]([tex].5^{2}[/tex]) A = [tex]\pi (2.5^{2} )[/tex]
A = .25[tex]\pi[/tex] A = 6.25[tex]\pi[/tex]
A = .79 A = 19.63
19.63/10 for [tex]in^{2}[/tex] per $1
So the 1in pizza bite is $1 for .79[tex]in^{2}[/tex] and we can see from the 10in pizza it's $1 for 1.96[tex]in^{2}[/tex]. So it is much better to get the 10in pizza.

Caleb brought groceries and paid $1.60 in sales tax. The sales tax rate is 2.5%. What was the price of caleb’s groceries, before tax?
Answer:
$64
Step-by-step explanation:
We can set up a percentage proportion to find the value Caleb's groceries before tax.
[tex]\frac{1.60}{x} = \frac{2.5}{100}[/tex]
We can cross multiply to find the value of x.
[tex]100\cdot1.60=160\\\\160\div2.5=64[/tex]
So the original cost before tax was $64.
Hope this helped!
Answer:
$1.64
Step-by-step explanation:
We need to find the before tax price so let that be x
100-2.5% = 97.5% (since this is the reduction before the sale)
Turn this percentage into a decimal so 0.975
To find x we must remember this price multiples 0.975 to give us $1.60
x * 0.975 = 1.60
x = 1.60 / 0.975
x = 1.64 (2dp)

Solve the inequality z−18≥−23 and write the solution in interval notation, using improper fractions if necessary
Answer: [-5,∞)
Step-by-step explanation:
z-18 ≥ -23 Add 18 to both sides
+18 +18
z ≥ -5
Which means x has to be greater than negative 5.
In interval notation it will be [-5,∞)
Answer:
z ∈ [-5; +∞)
Step-by-step explanation:
z - 18 ≥ - 23
<=> z ≥ 18 - 23
<=> z ≥ -5
----> z ∈ [-5; +∞)

The golfer with the highest score in a tournament was nine over par. The golfer with the lowest was five below par. What was the range in golf scores?
Answer: The range in golf scores was 14.
Step-by-step explanation:
Range = Maximum - minimum
Values above some limit are represented by positive integers whereas values blow a certain limit is represented by negative numbers.
Given: The golfer with the highest score in a tournament was nine over par i.e. (9). The golfer with the lowest was five below par i.e. (-5 ).
So, the range in golf scores = 9-(-5)
= 9+5
= 14
Therefore, the range in golf scores was 14.

Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]

I enter the garden. There are 34 people. You hug 30. How many people are in the garden.
Answer:
34
Step-by-step explanation:
There are 34 people in the garden prior to the time I joined them.
So when I entered the garden, the total number of people in the garden will be:
34 + 1 = 35 peopleLet assume, you as the reader was part of the people in the garden and you hugged 30 people. That doesn't add up or increase the number of people in the garden.
At the end of the day, the number of people you did not hug is:
35 - 30 - 1(you)
= 35 - 31
= 4 people
Therefore, we can conclude that there are 35 people present in the garden.

If x and y are consecutive positive integers and x2 – y2 = 11, what is the value of y?
E. 1
F. 3
G. 5
H. 6
please provide explanation
Answer:
y = 5
Step-by-step explanation:
We khow that x and y are consecutive integers and that x^2 is greater than y^2 since x^2-y^2=11
● so x is greater than y
● wich means that x = y+1
● x^2-y^2=11
● (y+1)^2-y^2 = 11
● y^2+2y+1-y^2=11
● 2y + 1 = 11
● 2y +1-1 = 11-1
● 2y = 10
●2y/2 = 10/2
● y = 5

a car manufacturer claims that their car can get 32 miles per gallon minus the speed factor. thus caj be modeled by linear equatioj f (×) =33 -015x where f(×) represents the miles per gallon and x is the mph . what would be the predicted miles per gallon for a car going 60 mph using this equation?
Answer:
f(x) = 24 miles per gallon
Step-by-step explanation:
car manufacturer claims that their car can get 33 miles per gallon minus the speed factor
f (×) =33 -0.15x
For a car going 60 mph
f (×) =33 -0.15x
X=60 mph
f (×) =33 -0.15x
f(x) = 33-0.15(60)
f(x) = 33-9
f(x) = 24 miles per gallon
