Answer:
P=1/65.
Step-by-step explanation:
We knaow that one coin in a collection of 65 has two heads. If a coin, chosen at random from the lot and then tossed, turns up heads 6 times in a row. We calculate the probability that it is the two-headed coin.
We calculate the number of possible combinations:
Number of favorable combinations is 1.
Therefore, the probability is
P=1/65.
I think that the correct answer to this question is E.) 90 .
Answer:
(0, -5)
Step-by-step explanation:
When we rotate a point around the origin 180°, the original coordinates (x, y) become (-x, -y).
So,
-0 is just 0 (since 0 is both negative and positive)
-(5) is -5
This makes our new point (0, -5).
Hope this helped!
Answer:
C
Step-by-step explanation:
the angle in a semicircle = 90° , that is the 3rd angle in the triangle.
the sum of the 3 angles in a triangle = 180° , then
p + 90° + 42° = 180°
p + 132° = 180° ( subtract 142° from both sides )
p = 48°
