Part A)
The coin landed on heads 9 times out of 30 flips, so the experimental probability is 9/30, which reduces to 3/10 probability.
Part B)
Theoretically a coin has a 1/2 probability of landing on heads each flip
Answer:
x > 4
Step-by-step explanation:
Calling x the number of days Rita needs to bake the total amount of cakes, then inequality is x*8 > 32. Because she has orders for more than 32 cakes and can make 8 cakes per day. Dividing by 8 every side of the inequality gives: x > 4. Graph of the solution is attached (notice that 4 is not included).
Answer: (9,5) and 2
Step-by-step explanation:
Get the difference between the coordinate points (9,5)
Multiply by 2
Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :

One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :

So, the other factor is (3-x).
There are 13 spades in a standard deck of cards, so if the first one is a spade, there are 12 spades left.
So the chances of getting another one would be 12/52 because there are 52 cards in a standard deck of cards.
Reduced, your answer is 3/13
