3. Solve the following system of equations. 2x +y +z = 11
3x + 5y + 5z = 34
5x + 6y + 3z = 42
Part A (10 points) Solve using Gaussian
elimination or a matrix. If you use a
matrix, you must write out your original
matrix and answer matrix. Show your
answer as a point (x, y, z)
I
Part B (2 points) Show that your
solution works in at least one of the
original equations.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

depends on how many days you are talking about
