. Tommy has started in a total of 109 RHS games, all football and baseball. The number of baseball games he started was five less than twice the number of football games he started. How many football games did Tommy start?​

Answers

Answer:

Let's denote the number of football games Tommy started as "f" and the number of baseball games he started as "b."

We're given two pieces of information:

Tommy has started a total of 109 RHS games:

f + b = 109 (Equation 1)

The number of baseball games he started was five less than twice the number of football games he started:

b = 2f - 5 (Equation 2)

We can solve this system of equations to find the value of "f," which represents the number of football games Tommy started.

Substitute Equation 2 into Equation 1:

f + (2f - 5) = 109

Combine like terms:

3f - 5 = 109

Add 5 to both sides:

3f = 114

Divide both sides by 3:

f = 38

Therefore, Tommy started 38 football games.

Steve is correct. Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0.

By using a number line, Steve can find the difference in temperature between 7 AM and 12 PM on Wednesday by adding the distances from 0. One temperature is negative and the other is positive, but by adding their distances, he can find the difference. Kelly's method of subtracting -5.1 from the temperature at 12 PM on Wednesday is not necessarily incorrect, but it does not give the exact difference in temperature between the two times. Therefore, using Steve's method, the change in temperature would be the sum of the distance from 0 to the temperature at 7 AM (which is 2.5) and the distance from 0 to the temperature at 12 PM (which is also 2.5), resulting in a difference of 5 degrees.

Select two lines, preferably two that cross on your blueprint, and use the substitution
method to solve for their intersection point.
Mark each intersection point using a YELLOW POINT on your blueprint.
Repeat this for a total of three intersecting lines.
Example problem:
Y = -2X + 14 and Y = 3X-7
Intersection point = (4.2, 5.6)
-2X+14=3X-7
-2X=3X-21
5X=-21

Y = -2(4.2) + 14
Y = -8.4 + 14
Y = 5.6

Answers

Marking the intersection points on the blueprint with yellow points:

Intersection point of Equations 1 and 2: (7, 0)Intersection point of Equations 1 and 3: (11.2, -8.4)Intersection point of Equations 2 and 3: (3.6, 3.8)

How to determine intersection point?

To solve for the intersection points of three lines.

Equation 1: Y = -2X + 14

Equation 2: Y = 3X - 7

Equation 3: Y = 0.5X + 2

To find the intersection point of Equations 1 and 2, use the substitution method.

Substituting Equation 1 into Equation 2:

-2X + 14 = 3X - 7

Adding 2X and subtracting 14 from both sides:

-2X + 2X + 14 = 3X + 2X - 7 - 14

14 = 5X - 21

Adding 21 to both sides:

14 + 21 = 5X

35 = 5X

Dividing both sides by 5:

X = 7

Now substitute X = 7 back into Equation 1 to find the corresponding Y value:

Y = -2(7) + 14

Y = -14 + 14

Y = 0

Therefore, the intersection point of Equations 1 and 2 is (7, 0).

To find the intersection point of Equations 1 and 3, use the same substitution method.

Substituting Equation 1 into Equation 3:

-2X + 14 = 0.5X + 2

Adding 2X and subtracting 14 from both sides:

-2X + 2X + 14 = 0.5X + 2X - 14

14 = 2.5X - 14

Adding 14 to both sides:

14 + 14 = 2.5X

28 = 2.5X

Dividing both sides by 2.5:

X = 11.2

Now substitute X = 11.2 back into Equation 1 to find the corresponding Y value:

Y = -2(11.2) + 14

Y = -22.4 + 14

Y = -8.4

Therefore, the intersection point of Equations 1 and 3 is (11.2, -8.4).

To find the intersection point of Equations 2 and 3, substituting Equation 2 into Equation 3:

3X - 7 = 0.5X + 2

Subtracting 0.5X and adding 7 to both sides:

3X - 0.5X = 0.5X + 2 + 7

2.5X = 9

Dividing both sides by 2.5:

X = 3.6

Now substitute X = 3.6 back into Equation 2 to find the corresponding Y value:

Y = 3(3.6) - 7

Y = 10.8 - 7

Y = 3.8

Therefore, the intersection point of Equations 2 and 3 is (3.6, 3.8).

The area under the curve over [0, 1] is 15.75.

How to solve

To find the Riemann sum, divide [0, 1] into n equal subintervals of width Δx = 1/n.

Using the right endpoint, c = iΔx = i/n. The Riemann sum is:

Σ[f(c)Δx] = Σ[(21(i/n) + 21(i/n)³)(1/n)] from i=1 to n.

To find the area under the curve, take the limit as n→∞:

Area = lim(n→∞) Σ[(21(i/n) + 21(i/n)³)(1/n)].

Find the answer by using the method of definite integration.

Area = ∫(21x + 21x³)dx from 0 to 1 = [10.5x² + 5.25x⁴] from 0 to 1 = 10.5(1)² + 5.25(1)⁴ - 0 = 15.75.

Suppose that the common shares of Oceanic Luxury Vessels , Inc. , is trading for $ 38 a share and that 5 million shares are outstanding . The company also has 75,000 bonds outstanding , which are selling at 102 percent of par . If Oceanic Luxury Vessels , Inc. , was considering an active change to its capital structure so that the firm would have a D/E ratio of 1.6 , which type of security ( stocks or bonds ) would it need to sell to accomplish this , and how much would it have to sell ? A. Debt ; $ 349.9 million B. Stock : $ 445.2 million C. Debt ; $ 248.5 million D. Stock ; $ 289.4 million

Answers

Answer:

To have a D/E ratio of 1.6, Oceanic Luxury Vessels, Inc. would need to sell debt securities.

First, we need to calculate the market value of the company's equity.

Market value of equity = Number of shares outstanding × Market price per share

Market value of equity = 5,000,000 × $38

Market value of equity = $190,000,000

Next, we can calculate the current debt-to-equity (D/E) ratio of the company:

Current D/E ratio = Total debt / Total equity

Total debt = Number of bonds outstanding × Bond price per bond × Par value

Total debt = 75,000 × 1.02 × $1,000

Total debt = $76,500,000

Current D/E ratio = $76,500,000 / $190,000,000

Current D/E ratio = 0.403

To achieve a D/E ratio of 1.6, the company would need to increase its total debt by a factor of 1.6/0.403 = 3.97.

New total debt = 3.97 × $76,500,000

New total debt = $304,305,000

To calculate the amount of debt securities the company would need to sell, we can subtract the current total debt from the new total debt:

Amount of debt to be sold = $304,305,000 - $76,500,000

Amount of debt to be sold = $227,805,000

Therefore, the company would need to sell debt securities worth $227.8 million to achieve a D/E ratio of 1.6.

The correct answer is C. Debt; $248.5 million.

The average price of a college math textbook is $151 and the standard deviation is $24. Suppose that 40 textbooks are randomly chosen. Round all answers to 4 decimal places where possible.

What is the distribution of
X? X ~ N( , )

For the group of 40, find the probability that the average price is between $152 and $155.

Find the third quartile for the average textbook price for this sample size. $
(round to the nearest cent)

For part b), is the assumption that the distribution is normal necessary? YesNo

Answers

(a) The distribution of X is X ~ N(151, 24)

(b) The probability that the average price is between $152 and $155 is 0.950

(c) The quartile for the average textbook price for this sample size is $167.2

(d) The assumption of normal distribution is necessary

(a) What is the distribution of X?

Given that

Mean = 151

Standard deviation = 24

The distribution of X is represented as

X ~ N(Mean , Standard deviation)

So, we have

X ~ N(151, 24)

(b) The probability that the average price is between $152 and $155.

The z-score is calculated as

z = (x - Mean)/Standard deviation

So, we have

z = (152 - 151)/24 and z = (155 - 151)/24

Evaluate

z = 0.042 and z = 0.167

So, we have

P = P(0.042 < z < 0.167)

Evaluate

P = 0.95044

Approximate

P = 0.950

(c) Finding the third quartile

This is calculated as

Q₃ = Mean + 0.675 * Standard deviation

So, we have

Q₃ = 151 + 0.675 * 24

Evaluate

Q₃ = 167.2

Hence, the quartile for the average textbook price for this sample size is $167.2

(d) Is the assumption necessary

Yes, the assumption is necessary

This is because

The distribution has a sample size greater than 25 as required by the central limit theorem

The number of unique preferences represented in the table is given as follows:

B. Five.

What are unique outcomes?

Unique outcomes are the outcomes that appear in a data-set, however we only count them twice.

For example, if João and Elisa are Buffalo Bills fans, while Chanel and Laura are Atlanta Falcons fans, we have two unique outcomes(Bills and Falcons fans).

Hence the outcomes for this problem is given as follows:

Question 6
Sharron gets a total of £1050 each month.
She spends 3/10 of this on rent and 2/3 on food and bills.
How much money does Sharron have remaining?
Show your working out and write your answer in the box below.

Answers

The way that I would do it is turn 3/10 and 2/3 into decimals by dividing the 2 by 3 and 3 by 10

2/3 = 0.66 and 3/10= 0.3

Then multiply both by the total amount

1050 x 0.66 = 693
1050 x 0.3 = 315

Add them both together

693 + 315 = 1008

Then subtract 1008 from 1050

1050-1008 = 42
