Hey ,here is the answer to ur question....!
(a).p(that the first card is a queen)=4/52=2/26=1/13
P(the card is a queen if the sampling is done without replacement)=3/52
(B).p(the first card is a queen)=4/52=1/13
P(the second card is queen of the sampling is done with replacement)=1/13....
Hope this helps you....!
Answer:
5x-4=11
Step-by-step explanation:
so you multiply 5 times x (a number) and subtract 4 and it equals to 11
I think it is asking for the answer, therefore it would be AB = 10.7
Answer: Choice A) cone
One way to picture this is to think of a propeller. As the propeller spins, it carves out a 3D space even though the blade is "2D" in a sense.
If we spin everything around segment BC, we get a 3D cone forming. The base of the cone is vertical and it has a radius of AC. The height of the cone is segment BC. It might help to rotate the paper 90 degrees clockwise so that BC is vertical.
Answer:
AC = 3.72 units
Angles:
A = 132.6°
C = 27.4°
Step-by-step explanation:
AC² = 5² + 8² - 2(5)(8)cos(20)
AC² = 13.82459034
AC = 3.718143399
3.718143399/sin20 = 8/sinA
sinA = 0.7358944647
A = 180 - 47.38285134
A = 132.6171487
3.718143399/sin20 = 5/sinC
sinC = 0.4599340405
C = 27.38285134
