A stock has a beta of 1.30, the expected return on the market is 10 percent, and the risk-free rate is 4.6 percent. What must the expected return on this stock be? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.G., 32.16.)
Answer:
11.62%
Step-by-step explanation:
Calculation for What must the expected return on this stock be
Using this formula
Expected return=Risk-free rate+(Expected market return -Risk-free rate)*Beta
Let plug in the formula
Expected return=4.6%+(10%-4.6%)*1.30
Expected return=4.6%+(5.4%*1.30)
Expected return=0.046+0.0702
Expected return=0.1162*100
Expected return=11.62%
Therefore What must the expected return on this stock is 11.62%
The two lines y = 4x+5 and y = 4x – 2 are parallel because their slopes are equal (both equal to 4). What
happens when you try to algebraically solve for their intersection point?
Answer:
When solving, you will get a false statement, and therefore there is no solution.
Step-by-step explanation:
Let's try to solve the system of equations. In this case, I used the substitution method and substituted 4x + 5 for the y in y = 4x-2:
[tex]4x + 5 = 4x - 2\\5 = -2[/tex]
In trying to combine the terms with the variable x, the 4x on both sides canceled themselves out, leaving me with 5 = -2. That is a false statement, as 5 does not equal -2. Therefore, since we cannot reach a solution, there is none.
two lines y = 4x+5 and y = 4x – 2 are parallel, then there is no intersection point.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given wo lines are y = 4x+5 and y = 4x – 2
These two lines are parallel because there slope is 4 for both.
Let us solve these two equations algebraically to find out intersection point.
4x+5=4x-2
5=-2
Since 4x is cancelled on both sides and has no x variable means there is no intersection point.
Hence for two lines y = 4x+5 and y = 4x – 2 are parallel, then there is no intersection point.

Answer:
RT = 10
Step-by-step explanation:
Since, U and V are the midpoints of the segments RS and ST respectively.
Therefore,
By Mid-segment Theorem:
RT = 2UV
4x - 22 = 2(10x - 75)
4x - 22 = 20x - 150
150 - 22 = 20x - 4x
128 = 16x
128/16 = x
8 = x
x = 8
RT = 4x - 22 = 4*8 - 22 = 32 - 22 = 10
does anyone know how to solve 2x+3y=7 and 4x-5y=25 using substitution to solve the system of equations. PLEASE HELP ONLY IF YK IT
Answer:
Step-by-step explanation:
first, let us mark the two equations as i and ii
2x+ 3y = 7
or, 2x = 7-3y
or, x = (7-3y) ÷ 2.........................(i)
and let 4x-5y= 25............(ii)
Now, put the the value of x from (i) into (ii)
4[(7-3y) / 2] -5y = 25
2(7-3y) -5y = 25
14- 6y - 5y = 25
-11y = 11
y = -1
Now, put y = -1 back in (i)
x = (7-3y)/2
x = 10 /2
x = 5

Answer:
We notice about these areas that:
All areas are perfect squares ⇒ 1st
The sum of the areas of the two smaller squares is equal to the area of the larger square ⇒ 3rd
Step-by-step explanation:
Let us solve the question
∵ The perfect square number is the product of a number and itself
∵ The areas of given squares are 25 m², 9 m², and 16 m²
∵ 25 = 5 × 5, 9 = 3 × 3, 16 = 4 × 4
∴ 25, 9, and 16 are perfect squares
∴ All areas are perfect squares
∵ 9 m² and 16 m² are the areas of the two smaller squares
∵ 9 m² + 16 m² = 25 m²
∵ The area of the larger square is 25 m²
∴ The sum of the areas of the two smaller squares is equal to the area
of the larger square

Answer:
$840
Step-by-step explanation:
Callies family spends an average of $70 per month electric. At that rate what can that family expect to pay electric for 1 year
Note that:
1 year = 12 months.
Hence, if:
1 month = $70
12 months = $x
Cross Multiply
$x = 12 × $70
$x = $840
Therefore, the amount that family can expect to pay in 1 year(12 month) for electric = $840

A farmer knows that a crop she is growing requires 24 kg of fertilizer throughout the season. She has a measuring flask which when filled twice makes 1 kg of fertilizer. At this rate, how many times does she need to fill the flask to make the required amount of fertilizer for the crop?
Answer:
48 times
Step-by-step explanation:
From the above question, we know that:
2 times = 1 kg of fertilizer
A crop requires 24 kg of fertilizer
Hence:
1 kg of fertilizer = 2 times
24 kg of fertilizer = x
Cross Multiply
x = 24 kg × 2 times/1 kg
x = 48 times
She need to fill the flask 48 times to make the required amount of fertilizer for the crop

What is the tenth term of the sequence described by the following f1 = -2, tn =3tn-1
Answer:
The 10th term will be:
t₁₀ = 39366
Step-by-step explanation:
Given the sequence
tₙ = -3 tₙ₋₁
Given
t₁ = -2
substitute n = 2, to determine the 2nd term
tₙ = -3 tₙ₋₁
t₂ = -3 tₙ₋₁
t₂ = -3 t₂₋₁
t₂ = -3 t₁
t₂ = -3 × -2 ∵ t₁ = -2
t₂ = 6
substitute n = 3, to determine the 3rd term
tₙ = -3 tₙ₋₁
t₃ = -3 t₃₋₁
t₃ = -3 t₂
t₃ = -3 × 6 ∵ t₂ = 6
t₃ = -18
substitute n = 4, to determine the 4th term
tₙ = -3 tₙ₋₁
t₄ = -3 t₄₋₁
t₄ = -3 t₃
t₄ = -3 × -18 ∵ t₃ = -18
t₄ = 54
substitute n = 5, to determine the 5th term
tₙ = -3 tₙ₋₁
t₅ = -3 t₅₋₁
t₅ = -3 t₄
t₅ = -3 × 54 ∵ t₄ = 54
t₅ = -162
substitute n = 6, to determine the 6th term
tₙ = -3 tₙ₋₁
t₆ = -3 t₆₋₁
t₆ = -3 t₅
t₆ = -3 × -162 ∵ t₅ = -162
t₆ = 486
substitute n = 7, to determine the 7th term
tₙ = -3 tₙ₋₁
t₇ = -3 t₇₋₁
t₇ = -3 t₆
t₇ = -3 × 486 ∵ t₆ = 486
t₇ = -1458
substitute n = 8, to determine the 8th term
tₙ = -3 tₙ₋₁
t₈ = -3 t₈₋₁
t₈ = -3 t₇
t₈ = -3 × -1458 ∵ t₇ = -1458
t₈ = 4374
substitute n = 9, to determine the 9th term
tₙ = -3 tₙ₋₁
t₉ = -3 t₉₋₁
t₉ = -3 t₈
t₉ = -3 × 4374 ∵ t₈ = 4374
t₉ = -13122
substitute n = 10, to determine the 10th term
tₙ = -3 tₙ₋₁
t₁₀ = -3 t₁₀₋₁
t₁₀ = -3 t₉
t₁₀ = -3 × -13122 ∵ t₉ = -13122
t₁₀ = 39366
Therefore, the 10th term will be:
t₁₀ = 39366

Answer:
The domain of T is {5, -7, 4, 1} and the range is {5, -7, 4, 1}
Step-by-step explanation:
In the relation of a set of ordered pairs R = {(x, y)}
The domain of the relation is the set of values of xThe range of the relation is the set of values of y∵ The relation T is defined as follows, T= {(5, 5), (-7, 4),(4, 0), (1, -4)}
∵ The first number in each ordered pair represents x
∴ x = 5, -7, 4, 1
∴ The set of values of x = {5, -7, 4, 1}
∵ The domain of the relation is the set of values of x
∴ The domain of T = {5, -7, 4, 1}
∵ The second number in each ordered pair represents y
∴ y = 5, 4, 0, -4
∴ The set of values of y = {5, 4, 0, -4}
∵ The range of the relation is the set of values of y
∴ The range of T = {5, -7, 4, 1}

would the diner have sold if 40 glasses of orange juice had been sold?
Complete the table with equivalent ratios.
The number of cups of coffee restaurant sold for 40 glasses of orange juice had been sold is 48.
What are proportions?The word "proportion" generally refers to an amount that is divided into parts or shares. Two ratios are in proportion when they are equal, as stated by the definition of proportion. An equation or a statement that says anything to that effect means that two ratios or fractions are equal.
Given that, the D-Town restaurant sold 12 cups of coffee for every 10 glasses of orange juice.
So, the ratio of cups of coffee to glasses of orange is 12:10
The restaurant have sold 40 glasses of orange juice.
Let c number of coffee cups are sold for 40 glasses of orange juice.
So, the ratio is c:40
Then, the proportion (ratios are equal) is 12:10::c:40
10c=480
c=48
Therefore, the number of cups of coffee restaurant have sold for 40 glasses of orange juice had been sold is 48.

Mr. Irvine and Mr. Babyak left in separate cars at the same time on the same road , to see the Nascar Race in Dover, Delaware. Mr. Irvine drove 77mi/h and Mr. Babyak drove 71 mi/h. In how many hours will they be 18 miles apart?
Answer:
In 3 hours, they will be 18 miles apart.
Step-by-step explanation:
Given that:
Speed of Mr. Irvine = 77mi/h
Speed of Mr. Babyak = 71mi/h
Distance to be apart = 18 miles
Let,
t be the time.
We will subtract the speeds as both the cars are driving in the same direction.
Distance = Speed * Time
18 = (77-71)t
18 = 6t
6t = 18
Dividing both sides by 6
[tex]\frac{6t}{6}=\frac{18}{6}\\t=3[/tex]
Hence,
In 3 hours, they will be 18 miles apart.
Leaving work, Duncan drove at 30 mph for 20 minutes. Then he drove at 40 mph for 12 minutes to reach home. How far did he drive to get home?
So first, we're gonna split these into their own little sections.
If Duncan drove 30 mph for 20 minutes, we need to think about the time for now. One hour is 60 minutes, and 20 minutes is 1/3 of an hour. If it's 30 miles per hour, then we'd need to split that into thirds to give it the twenty minute value, so in twenty minutes he drove 10 miles.
For the second part, we're gonna do the same thing. 40 mph in twelve minutes. 60 divided by 12 is 5. Then split the 40 mph into fifths. 40 / 5 = 8. Every twelve minutes, he drove 8 miles.
Add 10 and 8, and he drove a total of 18 miles to get home.
