Answer:

FV= $436.72

Step-by-step explanation:

Giving the following information:

Initial cost (PV)= $500

Decrease rate (d)= 7% per year

Number of periods (n)= 2 years

<u>To calculate the future value after 2 years, we need to use the following formula:</u>

FV= PV / (1 + d)^n

FV= 500 / (1.07^2)

FV= $436.72

Answer:

  5. 8 ft

  6. y = 47x +110; 533 students in 2019

Step-by-step explanation:

4. Answered for you previously. See brainly.com/question/21087377.

__

5.

<u>Given</u>:

  triangular garden with base 7 ft and area 28 ft^2

<u>Find</u>:

  height of the triangle

<u>Solution</u>:

The formula for the area of a triangle is ...

  A = 1/2bh . . . . . where A is the area, b is the base length, and h is the height

Multiplying by 2/b, we can get a formula for the height. Using this formula, we can solve the problem.

  h = 2A/b

We can let h represent the height, and fill in the given data.

  h = 2(28 ft^2)/(7 ft)

  h = 8 ft

The height of the triangle is 8 feet.

6.

<u>Given</u>:

  (0, 110), (5, 345) . . . . . where the points represent ...

     (years after 2010, students using the hotline)

<u>Find</u>:

  a linear model for the data

  the number of students predicted for 2019

<u>Solution</u>:

The 2-point form of the equation for a line is ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

where the points are (x1, y1) and (x2, y2). Using the given points, our linear model is ...

  y = (345 -110)/(5 -0)(x -0) +110

  y = 47x +110 . . . . the linear model, where ...

     y is the number of students using the hotline

     x is the number of years after 2010

__

In 2019, x = 9, so y = ...

  y = 47(9) +110 = 423 +110 = 533

The number of students predicted to use the hotline in 2019 is 533.

professor190 [17]

Answer:

Option A) 9604

Step-by-step explanation:

We are given the following in the question:

Confidence level = 95%

Standard error = 1%

p = q = 0.5

Formula for sample size:

n = (z_{stat}\times \dfrac{p(1-p)}{\text{Standard error}})^2

z_{critical}\text{ at}~\alpha_{0.05} = 1.96

Putting values, we get,

n = (1.96\times \dfrac{0.5(1-0.5)}{0.01})^2 = 9604

Thus, the sample size must be

Option A) 9604
