Answer:
121
Step-by-step explanation:
31+90 = 121
180 - 121 = 59
180 - 59 = 121
At least 4 means its minimum value is 4 so n≥4
The probability that all five end up in alphabetical order is; 1/120.
<h3>What is the probability that the rack ends up in alphabetical order?</h3>
To evaluate the given probability; first, the number of possible arrangements is;
17P5 = 742,560 possible arrangements.
However, the chance of an alphabetical order arrangement in each case is; 1 out of 5! possible arrangements.
Hence, we have that the number of possible alphabetical arrangement is; (1/120) × 742,560 = 6188.
Hence, the required probability is; 6188/742,560 = 1/120

The highest common factor is found by multiplying all the factors which appear in both lists
a.(13-4b)(a+6)
13a-24b
13 and 24
so we have to factor this
13 =13×1
24=12×2=12 is 6×2=6 is 3×2=3 is 3×1=3×1
Therefore 1 and 1 get canceled
13×3=39
(a )39
like this we have to solve........
Answer:
x=12 if you divide you'll get 4
