Answer:
x = 5/33 or 0.151515151
Step-by-step explanation:
7(-6x-2) = 8(3x-4)
step 1: simplify the equation.
-42x - 14 = 24x - 4
step 2: isolate the variable (using the balance method).
-42x - 14 + 14 = 24x - 4 + 14
-42x = 24x + 10
-42x - 24x = 24x - 24x + 10
-66x = 10
step 3: solve for x.
x = 10 ÷ -66
x = 5/33
Answer:
A. P(A l B) = x
Step-by-step explanation:
For independent events A and B,
P(B | A) = P(B)
P(A | B) = P(A)
P(A ∩ B) = P(A)P(B)
If P(A) = x and P(B) = y then:
⇒ P(B | A) = y
⇒ P(A | B) = x
⇒ P(A ∩ B) = xy
Therefore, the correct solution from the options given is:
A. P(A l B) = x
Answer:
x = 10.
y = 11
Step-by-step explanation:
2x+3y=53
3x-y=19
x = 10; y = 11
