Answer:

[tex]Growth\ Rate = 0.2000[/tex] --- Year 1 to 2

[tex]Growth\ Rate = 0.3333[/tex] --- Year 2 to 3

[tex]Growth\ Rate = 0.0625[/tex] --- Year 3 to 4

[tex]Average\ Growth\ Rate = 19.86\%[/tex]

Step-by-step explanation:

Given

[tex]\begin{array}{cc}{Year\ 1} & {100} & {Year\ 2} & {120} & {Year\ 3} & {160} & {Year\ 4} & {170} \ \end{array}[/tex]

Solving (a): Growth Rates between each year

For Year 1 to 2.

[tex]Growth\ Rate = \frac{Year\ 2 - Year\ 1}{Year\ 1}[/tex]

[tex]Growth\ Rate = \frac{120-100}{100}[/tex]

[tex]Growth\ Rate = \frac{20}{100}[/tex]

[tex]Growth\ Rate = 0.2000[/tex]

For Year 2 to 3.

[tex]Growth\ Rate = \frac{Year\ 3 - Year\ 2}{Year\ 2}[/tex]

[tex]Growth\ Rate = \frac{160-120}{120}[/tex]

[tex]Growth\ Rate = \frac{40}{120}[/tex]

[tex]Growth\ Rate = 0.3333[/tex]

For Year 3 to 4.

[tex]Growth\ Rate = \frac{Year\ 4 - Year\ 3}{Year\ 3}[/tex]

[tex]Growth\ Rate = \frac{170-160}{160}[/tex]

[tex]Growth\ Rate = \frac{10}{160}[/tex]

[tex]Growth\ Rate = 0.0625[/tex]

Solving (b): The average growth rate

This is calculated as by calculating the mean value of the growth rates in (a)

[tex]Average\ Growth\ Rate = \frac{1}{3}(0.2000 + 0.3333 + 0.0625)[/tex]

[tex]Average\ Growth\ Rate = \frac{1}{3}(0.5958)[/tex]

[tex]Average\ Growth\ Rate = \frac{1}{3}*0.5958[/tex]

[tex]Average\ Growth\ Rate = 0.1986[/tex]

Convert to percentage

[tex]Average\ Growth\ Rate = 0.1986 * 100\%[/tex]

[tex]Average\ Growth\ Rate = 19.86\%[/tex]

Answer:

x = 3

Step-by-step explanation:

Multiply the first equation by -1, then add it to second equation.

 2x+9y = -12

-2x-7y = 8

-------------------

 2y = -4

Solve for y

2y = -4

y = -2

Plug value of y into one of the equations and solve for x

2x + 9(-2) = -12

2x  = 6

x = 3

Answer:

y = -¼x

Step-by-step explanation:

If you plot the points (32,-8), (24,-6), and (16,-4), you'll see that they are collinear.

The cost per hour for the labor will be $75

Total amount charged = $530.50

Amount charged for parts = $193

Number of hours used = 4.5 hours

Let the amount charged per hour = x

Therefore, the equation to solve the question will be:

193 + 4.5(x) = 530.50

193 + 4.5x = 530.30

Collect like terms

4.5x = 530.50 - 193

4.5x = 337.50

Divide both side by 4.5

4.5x/4.5 = 337.50/4.5

x = 75.

The cost of labor per hour is $75

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Option A:

No, since it is not the probability, or percentage of students that have ear pircings, it is the number, which can assume values larger than 1.

Option B:

Yes, since it is a probability, each customer is independent of other customers, and in each trial, there are only two possible outcomes. This is the correct answer.

Option C:

No, this is called inverse binomial, as we want to find the number of customers until one does something, not the probability of a number of customers doing something.

Answer:

4 feet

Step-by-step explanation:

Let x be the height of the tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals 2 and 1/2. Let us represent this information in an equation.

5/8*x=2 and 1/2

Let us convert our given mixed fraction into an improper fraction.

5/8*x=5/2

Let us multiply both sides of our equation by 8/5.

8/5*5/8*x=5/2*8/5

x=8/2

Answer:

x = 6

Step-by-step explanation:

8(2x − 14) + 13 = 4x − 27

solve everything in parentheses

16x - 112 + 13 = 4x - 27

subtract 4x from each side of the equation

16x - 4x - 112 + 13 = 4x - 27 - 4x

reduce

12x - 112 + 13 = -27

combine those known numbers

12x - 99 = -27

add 99 tooth sides of the equation

12x - 99 + 99 = -27 + 99

reduce

12x = 72

divide both sides by 12

12x / 12 = 72 / 12

reduce

x = 6

  x = 18

Step-by-step explanation:

The parallel lines cut the transversals proportionally.

  (2x -1)/40 = 21/24

  2x -1 = 35 . . . . . . . multiply by 40

Answer:

Since a blogger has 400 subscribers to her blog in January, and the number of subscribers has grown by a factor of 1.5 every month since the, to write a sequence to represent the number of subscribers in the 3 months that followed, the following reasoning has to be made:

January: 400 subscribers

February: 400 x 1.5 = 600 subscribers

March: 600 x 1.5 = 900 subscribers

April: 900 x 1.5 = 1,350 subscribers

The sequence to represent the number of subscribers in the 3 months that followed are :

First month = 600 subscribers

Second month = 900 subscribers

Third month = 1350 subscribers

The blogger has 400 subscriber to her blog in January.

The number of subscriber has grown by a factor of 1.5 every month since then.

Therefore, the sequence to represent the number of subscribers in the 3 months that followed can be calculated below

January Subscribers = 400

February Subscribers = 1.5 × 400 = 600

March Subscribers = 1.5 × 600 = 900

April subscribers = 1.5 × 900 = 1350
