Answer:

c. 0.80

Step-by-step explanation:

If two events A and B are mutually exclusive they cannot occur simultaneously, but they can occur independently and so their individual probabilities can be added.

P(A \cap B) = 0\\P(A \cup B) = P(A) + P(B)

Therefore:  P(A ∪ B) is:

P(A \cup B) = 0.3+0.5\\P(A \cup B) = 0.8

Thus, the answer is c. 080

In an AP with 18 terms the common difference is $-3$−3 . If the nth term is $-5$−5, what is its first term?
erastova [34]

Answer:

46

Step-by-step explanation:

The n th term of an AP  is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here d = - 3 and a_{18} = - 5 , thus

a₁ + (17 × - 3) = - 5

a₁ - 51 = - 5 ( add 51 to both sides )

a₁ = 46

Find the value of c such that the equation x^2 - c = 0 has 12 and –12 as solutions.
Sonbull [250]

Answer:

c=144

Step-by-step explanation:

The given equation is x^2-c=0

If this equation has 12 and -12 as roots, then the roots must satisfy the equation.

We substitute x=12 to obtain

12^2-c=0

144-c=0

Solve for c to get:

144=c

This implies that:

c=144

We could have also substitute x=-12 to get the same result.
