Answer:
(a)
(b) 
Step-by-step explanation:
GIVEN: Suppose that two cards are randomly selected from a standard
card deck.
TO FIND: (a) What is the probability that the first card is a club and the second card is a club if the sampling is done without replacement? (b) What is the probability that the first card is a club and the second card is a club if the sampling is done with replacement.
SOLUTION:
(a)
Probability that first card is club 


As sampling is done without replacement.
probability that second card is club 


Probability that first card is club and second card is club 

(b)
Probability that first card is club 


As sampling is done with replacement.
probability that second card is club 


Probability that first card is club and second card is club 

Answer: 8/343
Step-by-Step:
If two similar solids have a scale factor of a:b then,
The ratio of their surface areas (2D) is- a^2:b^2
The ratio of their volume (3D) is- a^3:b^3
First you want to square root the scale factor numbers to find the original value. Then you cube the original numbers to find the answer.
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.
Answer:
160
80
40
20
Step-by-step explanation:
You start with the first term that is given which would be
b(1)=<u><em>160</em></u>
That would be our first term, then we multiply by 0.5 which would be 1/2
which gives us 80 as it is a division
You take the next term that we have found (80) and then we do the same thing, multiply by 0.5 (1/2)
The answer will be negative 36
