use the row operations tool to solve the following system of equations, obtaining the solutions in fraction form.
10x + 5z = 5
8x + 2y + z = 4
3x + 3y - 4z = 5
2x - 2y + 4z = 1
give the values for x, y, and z with the fractions reduced to lowest terms (for example 4/7 rather than 8/14).
x =
y =
z =

According to the data set, where should the upper quartile line of the box plot be placed?

The birth weights of newborn babies in the unites states follow in a normal distrubution with a mean of 3.4 kg and standard deviation of 0.6 kg. reaserches interested in studying how. children gain weights decide to take random samples of 100 newborn babies and calculate the sample mean birth weights for each sample

Solve the inequaliy: (x^2+2)(x−2)^2(6−2x)> 0
