Suppose that a random man's height from a certain population has a normal distribution with mean of 70" and standard deviation of 3 and a random woman's height has a normal distribution with mean of 66' and standard deviation of 4". find the probability that a random woman is taller than a random man. (hint: the sum of two gaussian random yariables is a gaussian random variable with μ-hs and a variance of σ2-σ2+ ơy2).

i need the answer to this too but idk it ; -;

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

are there options? cause you ain’t. real specific
