At a glass vase factory, 2 out of the last 12 vases produced were chipped. Considering this
data, how many of the next 18 vases would you expect to be chipped?
Vases

3 vases chipped.

Step-by-step explanation:

Let's use a ratio:

chipped : all

     2      :   12

     1       :    6

     3      :    18

We can expect 3 out of 18 vases to be chipped.

i really dont know

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
