Step-by-step explanation:
Answer:
x = 70
Step-by-step explanation:
Interior angles of a 4 sided shape = 360
80+70 = 150
360-150 = 210
210/3 = 70
Answer:
Assume x is directly proportional to y :

when y is 9, x is 2:
substitute to find value of k :

Therefore, equation is:

Hey i think u forgot to insert the picture of the triangle lol
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Probability that they were left handed P(L)= 40%
Probability that they were Democrats P(D)= 47%
So, P(L∩D) = 135 = 0.13
Now, to check whether they are independent or not.
We will find P(L) × P(D) is given by

Since P(L) . P(D) ≠ P(L∩D)
So, they are not independent.
Hence, Option 'c' is correct.
