Answer:
4s¹²/(9t⁴)
Step-by-step explanation:
<u>Solving in steps:</u>
- (3s⁻⁴t⁷s⁰)⁻²(-2s²t⁵)² =
- 3⁻²s⁻⁴ˣ⁻²t⁷ˣ⁻²(-2)²s²ˣ²t⁵ˣ² =
- 1/9×s⁸t⁻¹⁴(4)s⁴t¹⁰ =
- 4/9 ×s⁸⁺⁴t⁻¹⁴⁺¹⁰ =
- 4/9 ×s¹²t⁻⁴=
- 4s¹²/(9t⁴)
0.5 to the fourth power equals 0.0625.

Step-by-step explanation:
a)The pressure at which will trigger a warning is
31 - 31*0.26 = 22.94 psi
b) The probability that that the TPMS will trigger warning at 22.94 psi, given that tire pressure has a normal distribution with average of 31 psi and standard deviation of 2 psi
where x = 22.94,
