Answer:
1. 10C4 = 210
2. 4C1 + 10C1 = 14
Step-by-step explanation:
There are total 4 types of cakes available. Chocolate, cherry, apple and plain cakes. If we select 10 cakes, the possibility that at least 1 cake is selected for every variant is 210. We use computation technique in statistics for this purpose 10C4. After calculation we get 210.
If we select 4 apple cakes and one chocolate cake then there will be 14 different ways to do this. It is assumed that the order does not matter.
Answer:
110
Step-by-step explanation:
24/80=33/x
80/24= 3 1/3
3 1/3*33=110
The formula is a subscript n = 6^n
Where a1 is the first term and d is the common difference of the sequence
Thus, the first term is 6, second term 36, then 216.....
thus the sequence is, 6, 36, 216, .....................
Therefore, this is a geometric sequence with a common difference of 6
Answer: $1000 investment
Step-by-step explanation:
Let
x-----------> <span>this week's allowance
we know that
(3/4)x-----------> </span><span>was spent on candy
and
(5/6)[</span>(3/4)x]-------> <span>was spent on gummy bears
(5/6)*(3/4)x=(15/24)x------> (5/8)x
the answer is
5/8</span>
