Answer:
p =43/2
Step-by-step explanation:
8/9 = 12/(p-8)
We can use cross products
8 * (p-8) = 9*12
Distribute
8p - 64 = 108
Add 64 to each side
8p -64+64 = 108+64
8p =172
Divide by 8
8p/8 =172 /8
p =43/2
Answer:
D: 6/36
Step-by-step explanation:
As we are given the sample space, the events that sum to 6 are:
{(1,5), (2,4), (3,3),(4,2),(5,1)}
Let n(S) be the number of items in sample spae
n(S) = 36
Let E be the event the sum is 6
Then,
n(E) = 6
So,
P(Sum of two cubes is 6) = n(E) / n(S)
= 6/36
So, the correct answer is:
D: 6/36 ..

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°
