Answer:
42mm
Step-by-step explanation:
Let the shortest side of the triangle be 5x, the middle side be 6x, and the longest side be 8x.
5x+6x+8x = 159.6
19x = 159.6
x = 159.6 ÷ 19
x = 8.4
Shortest side of triangle (5x) = 8.4 × 5
= 42
X is a variable
6 is a constant
3 is a coefficient

Answer: 0.3439
Step-by-step explanation:
Total number of digits : 10
The number of digits except zero =9
The probability of selecting non-zero number :-

Then, the probability that one such phone number , the last four digits do not include any zero:-

Then , the probability that for one such phone number, the last four digits include at least one 0:-

Hence, the probability that for one such phone number, the last four digits include at least one 0 is 0.3439 .
