It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23
Answer:
-12x = 60
Step-by-step explanation:
This is the type of problem that you just have to do a bunch of times until you get it right -- I don't think there's anything I can tell you that'll help you immediately. Ask for your teacher for more exercises of this sort or look it up online.
Good luck!
Answer:
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

Answer:
Area of given figure = 96 unit²
Step-by-step explanation:
Given:
Length of shape = 4 unit
Width of shape = 4 unit
Height of shape = 4 unit
Find:
Area of given figure
Computation:
All side of figure all equal
So,
Given figure is a cube
Number of faces of cube = 6
Area of base = side x side
Area of base = 4 x 4
Area of base = 16 unit²
Area of given figure = Area of base x Number of faces of cube
Area of given figure = 16 x 6
Area of given figure = 96 unit²
