Answer:

  1

Step-by-step explanation:

If A and B are mutually exclusive and A is certain to happen, then B is certain to never happen, so P(B) = 0. The probability of either of two mutually exclusive events is the sum of their individual probabilities:

  P(A or B) = P(A) +P(B) = 1 + 0

  P(A or B) = 1

Y=1/2x+3<br> -x+27=-6 <br><br> solve using substitution
Nat2105 [25]

Answer:

y= 19.5    x=33

Step-by-step explanation:

-x + 27= -6

(subtract 27 on both sides)

-x= -33

(divide by negative 1 on both sides)

x= 33

(substitute x into the first equation)

y= 1/2x + 3

y= 1/2(33) +3

y= 16.5 +3

y= 19.5

hope this helps :))

What is the Quotient of 1 and 2/3 divided by 2 and 3/5
Nostrana [21]

Answer:

  25/39

Step-by-step explanation:

For division of mixed numbers, it often works well to first convert them to improper fractions. Then the division proceeds in the usual way: "invert and multiply", or "dot, swap."

__

  1\dfrac{2}{3}\div2\dfrac{3}{5}=\dfrac{5}{3}\div\dfrac{13}{5}=\dfrac{5}{3}\cdot\dfrac{5}{13}\\\\=\dfrac{5\cdot5}{3\cdot13}=\boxed{\dfrac{25}{39}}
