A bag contains 6 red marbles, 2 blue marbles, and 1 green marble. What is the

1 answer:

6 0

We have 1 green and 8 non-green.

We get a probability of 8/9 of a non-green for the first marble and a probably of 7/8 for the second being non green, so

p = (8/9)*(7/8) = 7/9

Answer: 7/9

M∠A = 50°, c = 25, a = 19, m∠C=?<br><br>Using the Sine Law

Rama09 [41]

Answer:

m<C can not be computed

Step-by-step explanation:

m∠A = 50°, c = 25, a = 19, m∠C=?

Using the Sine Law

a/sin m<A = c/sin m<C

Substitute the given values

19/sin50 = 25/sinC

19sinC = 25sin50

19sinC = 19.1511

sinC = 19.1511/19

sinC = 1.0079

C = arcsin1.0079

Hence m<C can not be computed

I am thinking of a 3 digit number when I divide it by 5 I am left with a remainder of 3 when I divide it by 10 I am left with a

Answer:

any of 158, 168, 178, 188, 198

Step-by-step explanation:

If the remainder is 8 when divided by 10, the least-significant digit must be 8. (That will guarantee that division by 5 will give a remainder of 3.)

In order for a number with one hundred to round to 200 when rounded to the nearest 100, the tens digit must be 5 or larger. There are 5 numbers that meet these criteria:

158, 168, 178, 188, 198
