Answer:
6 / 51
Step-by-step explanation:
It is false.
Reason:
The probability of picking a black card at first is:
26 / 52 = 1/2
There are now 25 black cards and 51 cards in total.
The probability of picking another black card, if there's no replacement is now:
25 / 51
Now, there are 24 black cards and 50 cards left in total.
The probability of picking a black card without replacement now becomes:
24 / 50 = 12 / 25
Hence, the probability of picking three black cards without replacement is:
1/2 * 25/51 * 12 / 25 = 300 / 2550
In simplest form, it is 6 / 51
Answer: 147 cm²
Step-by-step explanation:
Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
Answer: Option C is correct!
Step-by-step explanation:
The range of function is [-1,-5] . so first option is incorrect.
Since graph of the function f(x)=-2sin(x) is shifted down by 3 because of -3
therefore option B is incorrect.
Period of the given function is 2pi because here b =1 and period of sinx function is given by 
therefore option D is also incorrect
Period of the function f(x) is always absolute value number in front of sinx which is given to be 2 here therefore option C is correct.!
