The middle angles of a rhombus are 90 degrees which means the other two angles of the triangle must total 90 degrees.
(8x +7) + (3x + 6) = 90
11x + 13 = 90
11x = 77
x = 7

The chance of rain is 20%, the chance of it being sunny is 60%, and the chance of it

Charra [1.4K]

Answer:

0.6 = 60% probability that it is either sunny or rainy.

Step-by-step explanation:

We solve this question treating these events as Venn probabilities.

I am going to say that:

Event A: Rain

Event B: Sun

The chance of rain is 20%

This means that $P(A) = 0.2$

The chance of it being sunny is 60%

This means that $P(B) = 0.6$

The chance of it being sunny and rainy at the same time is 10%.

This means that $P(A \cap B) = 0.1$

Calculate, the probability that it is either sunny or rainy.

This is:

$P = P(A) + P(B) - 2P(A \cap B) = 0.2 + 0.6 - 0.2 = 0.6$

0.6 = 60% probability that it is either sunny or rainy.

Can someone help? If b/a=c/b=d/c=2/3, find a:b:c:d.

blagie [28]

Answer: a:b:c:d = 16:24:30:40

You can also divide the ratio by 2 because all terms have 2 in common. Which would be a:b:c:d = 8:12:15:20
