When Fowler inc, just paid a dividend, the price in 15 years for the share is $72.36.

This will be illustrated as:

P0 = D1 / (Ke - g)

P0 = Current Price

D1 = Expected Dividend after 1 Year

Ke = COst of Equity

g = Growth Rate

Dividend for first year will be:

D1 = D0(1+g)

= $ 2.55 (1+0.039)

= $ 2.55(1.039)

= $ 2.6495

Current price will be:

P0 = D1 / (Ke - g)

= $ 2.6495 / (0.104-0.039)

= $ 2.6495 / 0.065

= $ 40.76

Price in 15 years will be

P15 = D16 / (Ke - g)

P15 = Price after 15 Years

D16 = Expected Div after 16 Years

Ke = COst of Equity

g = Growth Rate

D16 = D0(1+g)^16

= $ 2.55 (1+0.039)^16

= $ 2.55(1.039)^16

= $2.55 * 1.8444

= $ 4.7031

P15 = D16 / (Ke - g)

= $4.7031 / (0.104-0.039)

= $4.7031 / 0.065

The probability that a randomly selected student is taking a math class or an English class is 0.88

And the probability that a randomly selected student is taking neither a math class nor an English class 0.12

In this question, we have been given in a large school, it was found that 80% of students are taking a math class, 75% of student are taking an English class, and 67% of students are taking both.

Let A represents math class, B represents English class

P(A) = 0.80

P(B) = 0.75

P(A ∩ B) = 0.67

We need to find the probability that a randomly selected student is taking a math class or an English class.

P(A U B) = P(A) + P(B) - P(A ∩ B)

P(A U B) = 0.80 + 0.75 - 0.67

P(A U B) = 0.88

Also, we need to find the probability that a randomly selected student is taking neither a math class nor an English class.

P(~(A U B) ) = 1 - P(A U B)

P(~(A U B) ) = 1 - 0.88

P(~(A U B) ) = 0.12

Therefore, the probability that a randomly selected student is taking a math class or an English class is 0.88

And the probability that a randomly selected student is taking neither a math class nor an English class 0.12

Answer:

(a) 31 years

(b) 59 years

(c) 56 years

Step-by-step explanation:

In general, when reading a stem and leaf plot, we read firstly the number in the steam (middle) and then in the leaf.

Now, let's move on to the question:

(a) As we can see in the graph, the youngest actor has 31 years.

(b) The youngest actress is 21 years old and the oldest is 80.

So, the difference is 80 - 21 = 59 years.

(c) In this exercise, we have to look for actors who had the same age. That means, when evaluating the steam, we will have to find similar values in the leaf. The oldest age shared is 56 years.

The rule of the slope of a line has 2 points is

A = (1, -2), B = (3, 4), C = (-2, 6)

We will take the altitude from A to the opposite side of BC

Then we will find the slope of BC first

x1 = 3 and y1 = 4. point B

x2 = -2 and y2 = 6. point C

We will substitute them in the rule above

The slope of BC = -2/5

Since the product of the slopes of the perpendicular line is -1, then if the slope of one is m, then the slope of the other will be -1/m, we reciprocal it and change its sign, then the slope of the altitude of BC should be 5/2

The form of the equation in point-slope is

y - y1 = m(x - x1)

m = 5/2

Since point A is lying on the altitude from A to BC, then

x1 = 1 and y1 = -2 point A

Substitute m and coordinates of point A in the form of the equation above

y - (-2) = 5/2 (x - 1)

The equation of the altitude from A to BC is

y + 2 = 5/2 (x - 1)

The percentage increase or decrease can be calculated by :

7. New = 13, Orig = 10

% change = [(13 - 10)/10] x 100 = 30% (Increase)

% change = [(3 - 5)/5] x 100 = -40% or 40% (decrease)

The next nice year will be 2 nice.

The nice year that will be the first one after it is 4 nice.

It should be noted that an exponent is used to express the numbers that are either too big or too small. This is usually expressed in their powers.

Fron the information, it as stated that a year is called "nice" if its number can be represented as the difference of two powers of two.

The next nice year will be the difference which will be

= (2² - 2) × nice

= (4 - 2) × nice

= 2 nice.

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient so equation of line d is y = -5x + c.

Substitute (2,-6) into the equation to find c.

-6 = -5(2) + c

c = 4

Hence equation of line d is y = -5x + 4.

Answer

Options A, D and E are correct.

The two functions are increasing.

The function for plan II has a greater unit rate.

The function for plan I has a greater y-intercept.

Explanation

The slope and y-intercept form of the equation of a straight line is given as

y = mx + b

where

y = y-coordinate of a point on the line.

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

b = y-intercept of the line.

For the first plan, there's a one time investment of 15,000 dollars and subsequent monthly payments of 500 dollars.

y = 15,000 + 500x

y = 500x + 15,000

Slope = unit rate of increase = 500

y-intercept = 15,000

For the second plan, the function is just given as

y = 12,000 + 520x

y = 520x + 12,000

Slope = unit rate of increase = 520

y-intercept = 12,000

We can see that

The two functions are increasing.

The function for plan II has a greater unit rate.

The function for plan I has a greater y-intercept.

The margin error M.E. that corresponds to a sample of size 22 with a mean of 69.3 and a standard deviation of 8.6 at a confidence level of 95% is 0.04694

We would utilize the t distribution in the estimation of the margin of error because the population standard deviation is unknown (and the sample size is less than 30).

Error margin = t-critical * standard deviation/square root sample size

It is given in the above question that,

Standard deviation is given as = 8.6

And, the Sample size which is given is = 22

Also, the confidence level which given is = 95%

Then the alpha will be = 100% - 95%

= 5% = 0.05

Now, the critical value, t would be = alpha / 2

= 0.05 /2 = 0.025

Also, the sample we'll consider will be = given sample size - 1 = 22 -1 = 21

To find the margin error, we'll put all the values in the formula

Error margin = t-critical * standard deviation/square root sample size

=  [tex]\frac{0.025 * 8.6}{\sqrt{21} }[/tex]

= 0.215 / 4.58

= 0.04694

Hence, the margin error M.E. that corresponds to a sample of size 22 with a mean of 69.3 and a standard deviation of 8.6 at a confidence level of 95% is 0.04694

Explanation:

A proportional relationship means that the two variables are related by a constant called constant of proportionality:

k is the constant of proportionality.

To find k we have to use the values of a and b from the table:

Answers:

• equation: ,a = 8/3 b

• constant of proportionality:, 8/3

Slope intercept form:

y = mx + b

m = (y2 - y1)/(x2 - 1) = (-8 - 1)/(2 - (-1)) = -9/(2 + 1) = -9/3 = -3

m = -3

If we take one of the point, for example (2, -8) and use it on the equation with the slope we already found:

y = -3x + b

-8 = -3(2) + b

Solving for b:

-8 = -6 + b

b = -8 + 6 = -2

b = -2

Therefore, the equation is: y = -3x -2

Answer:

y = -3x -2
