stepan [7]

Answer:

<h2>there are 22 dimes</h2><h2>there are 44 nickles</h2><h2 />

Step-by-step explanation:

D be dimes and N be nickles

2 nickles as dime

nickle = 5 cents and dime =10 cents

N=2D

0.10 D + 0.05 (N)=4.4 substitute N=2D

0.10 D +0.05(2D)=4.4

0.10D+0.10D=4.4

0.20 D=4.4

D=4.4/0.2 = 22

<h2>there are 22 dimes</h2>

N=2D

N=2(22)

N=44

<h2>there are 44 nickles</h2>

check : 0.10(22)+0.05(44)= 4.4 (correct)

How does the job satisfaction score for weeks 5-8 compare to weeks 1-4?

MrRa [10]

The correct comparison for Weeks 5-8 is higher than Week 1-4, hence, the job satisfaction for Week 5-8 is 17% higher.

<u>Job Satisfaction Score</u> :

Week 1 = 3.50
Week 2 = 3.40
Week 3 = 3.30
Week 4 = 3.60
Week 5 = 4.20
Week 6 = 4.00
Week 7 = 4.10
Week 8 = 3.90

<u>Job Satisfaction for week 1 - 4</u> :

Week 1 + Week 2 + Week 3 + Week 4
(3.50 + 3.40 + 3.30 + 3.60) = 13.80

<u>Job Satisfaction for Week 5 - 8</u> :

Week 5 + Week 6 + Week 7 + Week 8
(4.20 + 4.00 + 4.10 + 3.90) = 16.20

<u>Difference</u><u> between the two categories</u> :

[(Week 5 - 8) - (Week 1-4)] / Week 1-4] × 100%

(16.20 - 13.80) / 13.80 × 100%

(2.4 / 13.80) × 100%

0.1739 × 100%

= 17.39%

Therefore, the job satisfaction for Week 5 - 8 is about 17% higher than Week 1 - 4
