Na experiment on relaxation techniques, subject's brain signals were measured before and after the relaxation exercises with the following results: person 1 2 3 4 5 before 37.2 41.7 37.4 37.2 38.8 after 31.6 37.3 33.1 33.3 37.7 is there sufficient evidence to suggest that the relaxation exercise slowed the brain waves? assume the population is normally distributed. select the [p-value, decision to reject (rh0) or failure to reject (frh0)]. a) [t = 0.287, p-value = 0.773, rh0]

b) [t = 0.308, p-value = 0.773, frh0]

c) [t = 0.308, p-value = 0.193, rh0]

d) [t = 0.287, p-value = 0.387, rh0]

e) [t = 0.308, p-value = 0.387, frh0]

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

answer: c
