Answer:

m\angle E = 20\degree \\m\angle F = 50\degree

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

\therefore m\angle E = 2x\\\&  \: m\angle F = 5x \\\because m\angle E + m\angle F = 70\degree \\\therefore 2x + 5x = 70\degree \\\therefore 7x = 70\degree \\\therefore x = \frac{70\degree}{7}\\\therefore x = 10\degree \\\implies m\angle E = 2x= 2\times 10\degree = 20\degree \\\& \:  m\angle F = 5x=5\times 10\degree = 50\degree \\

inysia [295]

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

The length of one side of a square city block is 462 meters. what is the perimeter of the block
trapecia [35]
The perimeter of any shape is just what you get when you add up all of the side lengths. We know that one side is 462 meters, and since a square has four equal sides, we can just mulitply 462 × 4 to get our perimeter, 1,848 meters.
