Tracy's total investment is $4,940. The Option A is correct.

An investment basically means the process of exchanging income during one period of time for an asset that is expected to produce earnings in future periods.

To find Tracy's total investment, we need to calculate the cost of buying 150 shares of Upton Group and 100 shares of WHI Health.

For 150 shares of Upton Group:

Total cost = number of shares × offer price

Total cost = 150 × $18.96

Total cost = $2,844

For 100 shares of WHI Health:

Total cost = number of shares × offer price

Total cost = 100 × $20.96

Total cost = $2,096

Tracy's total investment is the sum of these two costs:

Total investment = $2,844 + $2,096

Total investment = $4,940.

Answer: I think 47.5in^2

Step-by-step explanation:

The probability of needing exactly 4 rolls to get doubles is 0.12.

What is meant by probability?

An event's probability is a numerical representation of how likely it is that the event will take place. In mathematical notation, it is written as a number between 0 and 1, or as a percentage between 0% and 100%. The higher an event's probability, the more likely it is to occur. In a sample space, there is a probability of 1 for each event. The probability formula states that the ratio between the number of favourable outcomes and the total number of outcomes determines the likelihood that an event will occur. Sets are used in the terminology of probability theory. A set is a grouping of various things.

From the figure,

The number of times we get doubles in 1 roll = 5

The number of times we get doubles in 2 rolls = 4

The number of times we get doubles in 3 rolls = 4

The number of times we get doubles in 4 rolls = 3

The number of times we get doubles in 5 rolls = 3

The number of times we get doubles in 6 rolls = 2

The number of times we get doubles in 7 rolls = 3

The number of times we get doubles in 8 rolls = 0

The number of times we get doubles in 9 rolls = 1

Total number of outcomes = 5+4+4+3+3+2+3+1  = 25

Number of doubles in 4 rolls = 3

The probability of needing exactly 4 rolls to get doubles = 3/25 = 0.12

Therefore the probability of needing exactly 4 rolls to get doubles is 0.12.

To determine the values of r for which v is in the span of S, we need to find a scalar multiple of the vector in S that equals v.

In other words, we need to solve the equation:
v = c* S
where c is a scalar and S is the vector in the span. Plugging in the values for v and S, we get:
\[\left[\begin{array}{c}2 \\ r \\ -1\end{array}\right] = c*\left[\begin{array}{c}1 \\ 0 \\ -1\end{array}\right]\]
To solve for c, we can equate the corresponding entries of the two vectors:
2 = c*1
r = c*0
-1 = c*-1
From the first equation, we get c = 2. Plugging this value into the third equation, we get:
-1 = 2*-1
which simplifies to:
-1 = -2

This equation is not true, so there is no value of c that satisfies all three equations.
Therefore, there is no value of r for which v is in the span of S.
The vector v is not in the span of S for any value of r.

Given that diameter of a circle is 7 ft, its area to the nearest tenth is 38.5 square feet.

Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2 where r is the radius of the circle.

To find the radius, we can divide the diameter by 2: r = d/2 = 7/2 = 3.5 ft

Now we can plug this into the formula for the area:

A = πr^2

A = π(3.5)^2

A ≈ 38.48

Therefore, rounding to the nearest tenth, the area of the circle is approximately 38.5 square feet.

The given equation (5)/(x - 5) = 5 + (x)/(x - 5) is a conditional equation.

We can simplify the equation as follows:

(5)/(x - 5) - (x)/(x - 5) = 5

(5 - x)/(x - 5) = 5

Now, we can cross-multiply to get rid of the fraction:

5 - x = 5(x - 5)

Distributing the 5 on the right side of the equation gives us:

5 - x = 5x - 25

Adding x to both sides and adding 25 to both sides gives us:

By answering the above question, we may state that The circle's radius is  radius 8.5 feet as a result.

In more modern use, a circle's or sphere's length is equal to its radius, and it is one of the line segments connecting the object's centre and circumference. The phrase is derived from the Roman word circle, which also describes a waggon wheel's spokes. The radius of a circle is the separation of any points on its circumference from its centre. Often, it is denoted by "R" or "r". A line segment with one termination in the centre and one on the circle's perimeter is called a radius. Radius = circular diameter A circle's diameter is the portion that passes through its centre and has ends on the circle.

The formula for calculating a circle's circumference is:

C = 2πr

When r denotes the radius, C denotes the circumference, and denotes a mathematical constant roughly equal to 3.14159.

We are informed that the circle's diameter is 17 feet. We may solve for r by setting this equal to the circumference formula:

17π = 2πr

By multiplying both sides by 2, we obtain:

r = 17π / (2π)

The units are cancelled, leaving:

r = 17 / 2

Examining this expression results in:

r = 8.5 ft

Sharon worked 49 hours to earn $749.

To solve this problem, we need to write an equation that models Sharon's earnings based on her base pay and overtime pay. The equation is as follows:

Earnings = (Base pay x Regular hours) + (Overtime pay x Overtime hours)

Since Sharon earns a base pay of $14 per hour and time and a half for overtime, her overtime pay is $14 x 1.5 = $21 per hour. We can plug these values into the equation:

$749 = ($14 x 40) + ($21 x Overtime hours)

Solving for the overtime hours, we can rearrange the equation and isolate the variable on one side:

$749 - $560 = $21 x Overtime hours

$189 = $21 x Overtime hours

Overtime hours = 9

Answer:

Let's start by assigning variables to the unknowns in the problem:

Let x be the selling price of a cup of apple juice.

Then the selling price of a cup of lemon juice is 3/2 times x, or 1.5x.

Let y be the number of times 2 cups of lemon juice are sold (so y is an even number).

Then the number of times 5 cups of apple juice are sold is 5/2 times y, or 2.5y.

From the given information, we can set up two equations:

2.5y(x + 12) = 1.5xy (Mr Tan earns $12 more from apple juice than from lemon juice)

2(1.5x)y = 5(2.5y) (for every 2 cups of lemon juice sold, 5 cups of apple juice are sold)

Simplifying the second equation, we get:

3xy = 25y

Dividing both sides by y (which is non-zero since y is even), we get:

3x = 25

Solving for x, we get:

x = 25/3

Substituting x into the first equation and simplifying, we get:

y = 24

So Mr Tan sells 24 cups of lemon juice and 60 cups of apple juice. To find his total earnings, we can multiply the selling price by the number of cups sold for each juice and add them up:

Total earnings = 24(1.5x) + 60x

Total earnings = 36x + 60x

Total earnings = 96x

Substituting x = 25/3, we get:

Total earnings = 96(25/3)

Total earnings = 800

Therefore, Mr Tan earns $800 altogether.

Calculate the correlation coefficient (r) using the formula:
r = (ΣXY - (ΣX)(ΣY)/n) / sqrt([(ΣX^2 - (ΣX)^2/n)(ΣY^2 - (ΣY)^2/n)])

Plug in the given values into the formula:
r = (126.54 - (22)(66)/12) / sqrt([(45.8 - (22)^2/12)(369.94 - (66)^2/12)])

Simplify the formula and solve for r:
r = (126.54 - 121) / sqrt([(45.8 - 40.333)(369.94 - 363)])
r = 5.54 / sqrt[(5.467)(6.94)]
r = 5.54 / 4.967
r = 1.115

Make conclusions about the closeness of the linear relationship based on the value of r:
Since the value of r is close to 1, this indicates a strong positive linear relationship between the investments (X variable) and the main product's sales (Y variable).

Find the linear regression from variable Y to the X using the formula:
Y = a + bX

Calculate the slope (b) using the formula:
b = (ΣXY - (ΣX)(ΣY)/n) / (ΣX^2 - (ΣX)^2/n)

Plug in the given values into the formula and solve for b:
b = (126.54 - (22)(66)/12) / (45.8 - (22)^2/12)
b = 5.54 / 5.467
b = 1.013

Calculate the intercept (a) using the formula:
a = (ΣY - b(ΣX))/n

Plug in the given values into the formula and solve for a:
a = (66 - 1.013(22))/12
a = 44.714/12
a = 3.726

Plug in the values of a and b into the linear regression formula:
Y = 3.726 + 1.013X

Forecast the sales volume if the investment volume is planned to be 30 thousand Euro by plugging in the value of X into the linear regression formula:
Y = 3.726 + 1.013(30)

Answer: To find the area of the white part of the billboard, we first need to find the area of the entire billboard and then subtract the area of the non-white part.

The area of a triangle can be found using the formula:

Area = (1/2) x base x height

In this case, the white part of the billboard is a right-angled triangle with a height of 4 ft and a base of 2.5 ft (half of the total base of 4.5 ft).

The area of the entire billboard is:

Area = (1/2) x base x height

Area = (1/2) x 4.5 ft x 4 ft

Area = 9 ft²

The area of the non-white part of the billboard is:

Area = (1/2) x base x height

Area = (1/2) x 2.5 ft x 4 ft

Area = 5 ft²

Therefore, the area of the white part of the billboard is:

Area of white part = Total area - Area of non-white part

Area of white part = 9 ft² - 5 ft²

Area of white part = 4 ft²

So the area of the white part of the billboard is 4 square feet.

The median, Q₁, Q₃, lower fence and upper fence of the given data set are 82, 75, 83, 63 and 95.

What is Inter quartile range?

In a range of values, from lowest to highest, the IQR denotes the median 50% of values. Find the median (middle value) of the lower and higher half of the data first, then use that number to calculate the interquartile range (IQR). The first quartile (Q1) and third quartile (Q3) of these values (Q3). What separates Q3 from Q1 is known as the IQR.

Given data set : 72, 81, 82, 83, 83, 85, 100, 54, 75, 81, 83

Firstly, we will arrange the data into ascending order.

we get, 54, 72, 75, 81, 81, 82, 83, 83, 83, 85, 100.

Here, no. of terms is 11

So, Median = (n+1)/2 th = (11+1)/2 = 6th term

So, Median = 82.

Q₁ = (n+1)/4 th term = (11+1)4 th = 3rd term

                                                 = 75

Q₃ = 3(n+1)/4 th term = 9th term = 83

Inter-quartile range = Q₃ - Q₁

                                  = 83 - 75 = 8.

Now, Lower fence = Q₁ - 1.5*IQR

                              = 75 - 1.5× 8

                              = 75 - 12 = 63

       Upper fence = Q₃ + 1.5*IQR

                              = 83 + 1.5×8

                              = 83 + 12

2. when t is -2, it indicates that 1250 the population before 2 years was 1250

3. For t  - -2 population was more than 1000

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal.

a. To find the population of the fish species in 2005, we need to plug in t = 0 into the equation:

p = 5,000 .2^t

p = 5,000 .2^0

p = 5,000

Therefore, the population of the fish species in 2005 was 5,000.

b. When t is -2, it means we are two years before 2005, the year when the fish population in the lake was first surveyed. In other words, we are trying to find the population of the fish species two years before 2005. To do this, we plug in t = -2 into the equation:

p = 5,000 .2^t

p = 5,000 .2^-2

p = 5,000 .25

p = 1,250

Therefore, the population of the fish species two years before 2005 was 1,250.

c. The fish population at t = -2 is more than 1,000. We know this because we calculated that the population was 1,250, which is greater than 1,000.
