0.129 is the change in the growth rate of company.

According to statement

we have to find and compare the growth rate of the company weekly.

we use the growth rate formula is

GROWTH RATE = present - past / present

Substitute the values in this formula

1st week = 220-190 / 220

1st week = 0.136

2nd week = 252-220 / 252

2nd week = 32 / 252

2nd week = 0.126

3rd week = 290-252 / 290

3rd week = 0.131

4th week = 337 - 290 / 337

4th week = 0.139

5th week = 380 - 337 / 380

5th week = 0.113

6th week = 440 - 380 / 440

6th week = 0.136

7th week = 505 - 440 / 505

7th week = 0.128

Now we find the average value of growth rate

Average = 0.136 + 0.126+0.131+0.139+0.113+0.136+0.128 /7

Average = 0.909/7

Average = 0.129

So, 0.129 is the change in the growth rate of company.

Answer:

#1. 8.27

#2. 36

#3. 22

#4. 7.25

Step-by-step explanation:

#1: 60÷11=5.45  ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>

#2: 60÷5= 12 ----> 12×3= <u>36</u>

<u></u>

#3: Games- 35    Won- 14    Lost- 21

      In 1 Game  Manchester won =   14/35  =  2/5 games in 54 Game  Manchester won =  54 x  2/5   games

= 108 / 5

= 21.6

<u>= 22</u>

<u></u>

#4: 6 : 91 ⇒ n : 110

     6(110) ⇒ 91(n)

     660 ⇒ 91n

     660/91 ⇒ n

     <u>7.25=n</u>

Suppose that replacement times for washing machines are normally distributed with a mean of 9.3 years and a standard deviation o
Harlamova29_29 [7]

Answer:

The probability is 0.0643

Step-by-step explanation:

* Lets revise some definition to solve the problem

- The standard deviation of the distribution of sample means is called σM

- σM = σ/√n , where σ is the standard deviation and n is the sample size

- z-score = (M - μ)/σM, where M is the mean of the sample , μ is the mean

 of the population  

* Lets solve the problem

- The mean of the washing machine is 9.3 years

∴ μ = 9.3

- The standard deviation is 1.1 years

∴ σ = 1.1

- There are 70 washing machines randomly selected

∴ n = 70

- The mean replacement time less than 9.1 years

∴ M = 9.1

- Lets calculate z-score

∵ σM = σ/√n

∴ σM = 1.1/√70 = 0.1315

∵ z-score = (M - μ)/σM

∴ z-score = (9.1 - 9.3)/0.1315 = - 1.5209

- Use the normal distribution table of z to find P(z < -1.5209)

∴ P(z < -1.5209) = 0.06426

∵ P(M < 9.1) = P(z < -1.5209)

∴ P(M < 9.1) = 0.0643

* The probability is 0.0643

Step-by-step explanation:

In a deck of 52 cards, there are 4 kings and 4 queens

Selection of 3 kings out of 4 = 4 C 3 = 4

Selection of 2 queens out of 4 = 6

So, total number of selections = 4 x 6 = 24
