If two balanced die are rolled, the possible outcomes can be represented as follows. (1, 1) (2, 1) (3, 1) (4, 1) (5, 1) (6, 1) (1, 2) (2, 2) (3, 2) (4, 2) (5, 2) (6, 2) (1, 3) (2, 3) (3, 3) (4, 3) (5, 3) (6, 3) (1, 4) (2, 4) (3, 4) (4, 4) (5, 4) (6, 4) (1, 5) (2, 5) (3, 5) (4, 5) (5, 5) (6, 5) (1, 6) (2, 6) (3, 6) (4, 6) (5, 6) (6, 6) Determine the probability that the sum of the dice is 11.
Answer:
1/18Step-by-step explanation:
A die is known to have 6 faces. If n die are rolled, the total number of outcomes or sample space is expressed as;
n(S) = [tex]6^n[/tex] where;
n is the total number of dies
If two balanced die are rolled, the total number of sample space will be;
n(S) = [tex]6^2 = 36[/tex]
Since we want to to determine the probability that the sum of the dice is 11, the possible outcome or event will be;
n(E) = {(5, 6), (6,5)}
N(E) = 2
Probability = Possible outcome/Total outcome
Probability that the sum of the dice is 11 = n(E)/n(S)
Probability that the sum of the dice is 11 = 2/36
Probability that the sum of the dice is 11 = 1/18
If the standard deviation of returns on the market is 20 percent, and the beta of a well-diversified portfolio is 1.5. Calculate the standard deviation of this portfolio.
a. 30 percent.
b. 20 percent.
c. 15 percent.
d. 10 percent.
Answer:
a. 30 percent.
Step-by-step explanation:
Given that:
The standard deviation of returns = 20 percent
Beta = 1.5
Beta=Standard deviation of portfolio × correlation/Standard deviation of market × Correlation
Since Correlation with the market will be +1;
Then;
The Standard deviation of portfolio = 1.5 × 20%
The Standard deviation of portfolio = 30.00%

How to find how much percent 'a' is of 'b'?Suppose a number is 'a'
Suppose another number is 'b'
We want to know how much percent of 'b' is 'a'.
Then, it is calculated as:
[tex]\dfrac{a}{b} \times 100[/tex]
(in percentage)
Given that:
A price is decreased from 11 euros to 8 euros.We've to find the percent changePercent change shows how much percent of the initial amount is changed.
Since we're taking about 'change', so it doesn't matter whether this was a positive change or a negative change.
Percent change = Percent that "absolute difference of 11 and 8" is of "inital price 11"
Absolute difference of 11 and 8 = [tex]|11 - 8| =3[/tex] (in euros)
Initial price is 11 euros.
Then, we get:
Percent change in price = the percent which 3 is of 11.
Let 3 is x% of 11, then we get:
[tex]x = \dfrac{3}{11} \times 100 = 27.27\overline{27}\approx 27.27[/tex]
Thus, percent change in considered price for this case is approximately 27.27%

A downtown parking garage charges individuals to park a car according to the following rate schedule: $1.00 for the first hour, then $2 for each subsequent hour until the daily maximum charge of $9.00 is reached. These charges are represented in the graph below.
which of the following is true?
Answer:
In the graph, a white dot means that the value does not belong to the set, while the colored dot means that the value does belong.
Let's analyze each statement (from top to bottom)
1)The x-axis represents the number of hours, and the y-axis the charge.
Then let's find x = 2.
You can see that there is a colored dot at y = $3, and a white dot at y = $5.
Then the price for exactly two hours is $3, not $5.
Then this first statement is wrong.
2) You can assume that 20 minutes is in between x = 0 and x =1, then from that point, you can see that the equivalent value of y is $1. Then the individuals who park only for 20 minutes will be charged with $1,
This statement is wrong.
3) 1 hour and 15 minutes is in between 1 and 2 hours.
And as you can see, for 1 < x ≤ 2, the price is $3. Then this statement is correct.
4) Here we have x > 4.
In the graph you can see that all values of x > 4 are mapped into the black part of the graph, which is equivalent to the maximum charge of $9.
Then this statement is correct.
What is the value of x?

I believe it is x+3..
Step-by-step explanation:
Answer:
x = 5
which agrees with the first answer option listed
Step-by-step explanation:
Use the proportionality associated with similar triangles, considering that the larger triangle has sides:
x + (x+5) = 2 x + 5
and
(x+1) + (x-2) = 2 x - 1
and the smaller triangle:
x and (x-2)
The we build the following proportionality:
(2 x + 5) / x = (2 x - 1) / (x - 2)
cross multiply to eliminate denominators:
(2 x + 5) (x - 2) = x (2 x - 1)
operate:
2 x^2 - 4 x + 5 x -10 = 2 x^2 - x
combine like terms:
2 x^2 + x -10 = 2 x^2 - x
subtract 2 x^2 from both sides:
x - 10 = - x
add x to both sides:
2 x -10 = 0
add 10 to both sides
2 x= 10
divide both sides by 2:
x = 5

through the point (2, 3).
O y = 1/5x+3/10
O y = 5x + 13
y = 5x - 7
O y = -1/5x + 17/5
9514 1404 393
Answer:
y = 5x - 7
Step-by-step explanation:
We can make an equation for the perpendicular line by swapping the x- and y-coefficients, negating one of them. Then we can use that form with the given point to see what the constant is.
10x -2y = ...
Removing a common factor of 2 gives ...
5x -y = 5(2) -(3) = 7 . . . . using (x, y) = (2, 3), we can find the constant
Solving for y, we get ...
5x -7 = y . . . add y-7
y = 5x -7 . . . write in the desired form

Work out the number of sides of a regular polygon, if the interior angle is 177
Answer:
Let the number of sides be x.
One interior angle is 177°
One exterior angle is 180-177 (linear pair)
= 3°
Exterior angle × Number of sides = 360
3*x = 360
x = 360/3
x = 120
Therefore, the polygon has 120 sides.
If the interior angle of a polygon is 177° then the number of sides is 120.
What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments are referred to as its edges or sides.
We know, Interior angle = 180(n-2)/n, where 'n' is the number of sides.
Given, A regular polygon has interior angles of 177°.
Therefore,
177 = 180(n-2)/n.
177n = 180n - 360.
- 3n = - 360.
3n = 260.
n = 360/3.
n = 120.

In late June 2012, Survey USA published results of a survey stating that 55% of the 579 randomly sampled Kansas residents planned to set off fireworks on July 4th. Determine the margin of error for the 55% point estimate using a 95% confidence level. The margin of error is: _____% (please round to the nearest percent)
Answer:
The Margin of Error E [tex]\simeq[/tex] 4.1 %
Step-by-step explanation:
Given that:
The sample size = 579
The sample proportion [tex]\hat p = 55\%[/tex] = 0.55
From the confidence interval of 95%
The level of significance ∝ = 1 - C.I = 1 - 0.95 = 0.05
The critical value of [tex]Z_{\alpha/2 } = Z_{0.025} = 1.96[/tex]
Thus;
The Margin of Error E = [tex]Z_{\alpha/2 } \times \sqrt{{\dfrac {\hat p ( 1 - \hat p }{n}}[/tex]
The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 1 - 0.55) }{579}}[/tex]
The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.55 ( 0.45 )}{579}}[/tex]
The Margin of Error E = [tex]1.96 \times \sqrt{{\dfrac {0.2475}{579}}[/tex]
The Margin of Error E = [tex]1.96 \times \sqrt{{4.2746114 \times 10^{-4}}[/tex]
The Margin of Error E = [tex]1.96 \times .020675[/tex]
The Margin of Error E = 0.040523
The Margin of Error E [tex]\simeq[/tex] 0.041
The Margin of Error E [tex]\simeq[/tex] 4.1%

Find the error in the calculations below, if there is one:
Answer:
Between line 1 and 2
Step-by-step explanation:
4x³ +2x²- 6x+ 3 (Line 1)
note that +3 can be written as -(-3), giving us:
4x³ +2x² -6x - (-3)
if we group the first two terms and the last two terms, we will get
(4x³ +2x²) + [ -6x - (-3) ] (factor out 2x from first group and -3 from second group)
= 2x²(2x +1) -3(2x - 1 )
if we compare this with (Line2) we can see that the difference is in the sign of the last term inside the second group. Hence this is where the mistake is made Between line 1 and 2
By applying an straightforward approach we conclude that the error in the calculations shown in the statement occurred from line (1) to line (2).
