Select the correct answer. solve this system of equations using the inverse of a matrix. -1 + y = 8 4x + 3y = 12 1 – 7y + z = 15 [hint: ax = b and x = b4-1; a. b. = 4, y = 68 and 2 = 5.39 r = 68. y = 5.39 and 2 = 4 r = -1.76 y = 6.24 and 2 = 60.76 d. = 6.24, y = –1.76 and 2 = 60.76 r = 72 y = -4 and 2 = 12.78 e.

What is the least common multiple of 6 and 17?

The probability that a tutor will see 0, 1, 2, 3, or 4 students is given below determine the probability distribution's missing value.

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
