Answer:
2/9
Step-by-step explanation:
You multiply the probability of the green ball which is 8/12 by the probability of the purple ball which is 4/12 and you get 0.222 which is also 2/9.
Answer:
-22
Step-by-step explanation:
2y+5x-5x= 19-5x. x-x-2y=-1-x
2y= 19-5x. -2y=-1-x
÷2= ÷2. ÷-2 = ÷-2
y= 19/2 -5/2x. Y = 1/2 + x/2

Correct Question
Mara thinks x ≤ 6 will earn the highest score here.
David thinks x < 6 will.
Who is correct?
Answer:
Mara is correct
Step-by-step explanation:
In the above question, we are given two inequality equations
1) Mara: x ≤ 6
2) David : x < 6
For David , x < 6 means the score which is represented by x is less than 6
For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6
Therefore, Mara is correct because x ≤ 6 will earn the highest score here.
Answer:
68°
Step-by-step explanation:
As BA⊥BD, so ∠ABD = 90°
also, ∠ABD = ∠CBD + ∠ABC
⇒ 90° = 4x + 52° + 8x - 10°
⇒ 12x = 48°
⇒ x = 4°
now,
∠CBD = 4x + 52°
= 4(4°) + 52°
= 68°
