Answer:

116

Step-by-step explanation:

so to find angle bcs we need to find x and to find x we need to create an equation. 160= angle scd +anglebcs so we do 180=3x+17+12x+8 and solve for x

160=3x+17+12x+8

step 1 combine like terms

160=15x+25

step 2 subtract 25 from each side

135=15x

step 3 divide each side by 15

9=x

then we plug in 9 to 12x+8 and get 116

An urn contains 6 red marbles and 4 black marbles. Two marbles are randomly drawn (one by one) from the urn without replacement.

strojnjashka [21]

Answer: The required probability is $\dfrac{2}{15}.$

Step-by-step explanation: Given that an urn contains 6 red marbles and 4 black marbles. Two marbles are randomly drawn one by one from the urn without replacement.

We are to find the probability that both drawn marbles are black.

Let E and F denote the events of two marbles one by one without replacement and let S and S' denote the corresponding sample spaces.

Then, we have

$n(E)=^4C_1=4,\\\\n(F)=^3C_1=3,\\\\n(S)=^{10}C_1=10,\\\\n(S')=^9C_1=9.$

Therefore, the probability that both marbles are red is given by

$p=P(E)\times P(F)=\dfrac{n(E)}{n(S)}\times\dfrac{n(F)}{n(S')}=\dfrac{4}{10}\times\dfrac{3}{9}=\dfrac{2}{15}.$

Thus, the required probability is $\dfrac{2}{15}.$
