1.from a barrel of colored marbles you randomly select randomly select 6 blue, 4 yellow, 2 red, 3 green and 5 purple. find the experimental probablilty of randomly selecting a marble that is not yellow.

2/9
4/5
2/3
10/19

2.sally works in a afactory that produces 1,000 television each day. when 40 televsion were sampled it was found that 6 were defective estimate how many defective televisions are made each day.

17
152
196
248

3.if a coin is tossed and a number cube is rolled what is the probability that the coin shows heads and the number cube shows 3.

1/2
1/9
1/6
1/12

Number 1 is 4/5

Step-by-step explanation:

So first you add all of them together.4+2+3+5=20

Then subtract 4 since there is 4 that are yellow.4-20=16.

Then divide 20 by 2 and 16 by 2.20/2=10,16/2=8.

Then divide them by 2 again.10/2=5,8/2=4.

Now that you can't reduce them anymore just determine which is the numerator.

16/20=8/10=4/5

Solution:4/5

Hope this helps

(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

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
