A set of data with a normal distribution has a mean of 10 and a standard deviation of 2. Fifty percent of the data falls below which number?

a.5
b.10
c.8
d.12

21.4 i did it already for s1

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
