Answer: a) 59049, b) 15120, c) 126.
Step-by-step explanation:
Since we have given that
5 digit sequences from the integers 1,2,...9.
a) the digits can be the same.
Repetition is allowed.
So, Number of ways to form 5 digit sequences would be
b) the digits cannot be the same and the order in which they appear matters.
Repetition is not allowed and order is maintained, so we will use "Permutation":
c) the digits cannot be the same and the order in which they appear does not matter.
Repetition is not allowed and order is not maintained, so we will use "Combination":
Hence, a) 59049, b) 15120, c) 126.
Answer:
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
(2x+24)+(4x+43)+(x^2+1)=180
the awnser to this is x=8.
You plug in 8 into x
Angle 1: 2(8+24) --> 40
Angle 2: 4(8+43) -->75
Angle 3: (8^2+1) -->65
Check your work: add values together 40+75+65=180
Answer:
C
Step-by-step explanation:
If 9 members paid on the first day, this means they did not pay on the third day
The remaining people (everyone but the 9) paid on the third day
Therefore we must subtract to find out how many members paid on the third day
22 - 9 = 13
Each of the 13 members paid $12.80 which means we must multiply
13 × 12.80 = 166.40
In total, the grocery store collected $166.40 on the third day of the month
