Step-by-step explanation:
given that Etsy is an e-commerce website focused on handmade or vintage items and supplies, as well as unique factory-manufactured items. A shop owner on Etsy sells printed t-shirts and she wants to know what level of inventory she should maintain for the month of January. She gathers the January inventories of 8 other shop owners who sell printed t-shirts on Etsy. Their t-shirt inventories are listed below.
59 84 90 54 42 45 77 85
a) Mean = total /8 = 536/8 = 67
For median arrange in ascending order
42 45 54 59 77 84 85 90
Middle entries are 59 and 77
b) Median = average of 59 and 77 = 68
c) If highest changes to 100, data set becomes
42 45 54 59 77 84 85 100
sum increases by 10 i.e. 546
Mean = 546/8 = 68.25
Median will not change remain the same = 68
Mean increases and median stays the same
d) If Var = 369.1429
std dev = square root of variance
= 19.2131
e) Part b answer is the II quartile
f) Mean = 67 and median = 68
Mean < median
So negatively skewed shape
I believe a would be on the first line.
Answer:
Difference= $11,280
Step-by-step explanation:
Giving the following information:
Manager at Shop & Save Grocers= Hourly wages $16.50 per hour
Assistant Manager at Unbelievable Toys= Monthly wages $3,800
Cashier at 7-12 Convenience Store= Yearly wages $43,000
<u>First, we need to calculate the yearly wages, and then compare the results:</u>
Shop & Save Grocers= (16.5*40)*52= $34,320
Unbelievable Toys= 3,800*12= $45,600
The highest paying job is at Unbelievable Toys.
Difference= 45,600 - 34,320= $11,280

Answer:
4 ft downwards
Step-by-step explanation:
old height off the ground :
7^2+b^2=25^2
49+b^2=625
b^2=576
b=24
new height off the ground :
7+8=15
15^2+ b^2 =25^2
225+b^2 = 625
b^2 = 400
b=20
difference between heights :
24 - 20 = 4
