Answer:

2.4 %

Step-by-step explanation:

annual growth is the changes in the value of asset

STEP 1: annual growth rate

= (current value - old value)/old value

= (4100 - 5000)/ 4100

= -0.2195 // 21.95%

Step 2: Mean of x

mean of x= average of x

          = total of x / count of x ( x here is the annual growth rate)

       = annual growth rate / no of years

        =  -0.2195/ 9

       = -0.02 // 2.4 %

lina2011 [118]

Answer:

Her regular weekly pay is $62 and her annual salary is $3100.

Step-by-step explanation:

Given that her hourly wage=$15.50 / hour

As she works 40 hours per week, so her weekly pay = 15.50 x 40 = $62/ week.

If she works 50 weeks each year, so her yearly pay = 62x50=$3100 /year.

Hence, her regular weekly pay is $62 and her annual salary is $3100.

Readme [11.4K]

Answer:

a) (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5)

b)

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

c)

  • F(x) = 0 if x<0
  • F(x) = 0.3 if 0 ≤ x < 1
  • F(x) = 0.9 if 1 ≤ x < 2
  • F(x) = 1 if x ≥2

Step-by-step explanation:

Lets call the boards 1,2,3,4 and 5

a) There are {5 \choose 2} = 10 possible outcomes: (1,2), (1,3), (1,4), (1,5), (2,3), (2,4),(2,5),(3,4), (3,5) and (4,5).

b) X is 0 if the selected boards doesnt contain 1 or 2. There are {3 \choose 2} = 3 possibilities for this, in concrete, (3,4), (3,5) and (4,5).

PX(0) = 3/10 = 0.3

There is only 1 possibility so that X = 2, which is (1,2), therefore

PX(2) = 1/10 = 0.1

In any other case (there are 6 remaining), X will be equal to 1, so

PX(1) = 6/10 = 0.6

Therefore, X has the following distribution

PX(0) = 0.3

PX(1) = 0.6

PX(2) = 0.1

c) F(0) = 0.3

F(1) = 0.3+0.6 = 0.9

F(2) = 1

We have, as a consequence

  • F(x) = 0 if x<0
  • F(x) = 0.3 if 0 ≤ x < 1
  • F(x) = 0.9 if 1 ≤ x < 2
  • F(x) = 1 if x ≥2
