An experimenter is studying the effects of temperature, pressure, and type of catalyst on yield from a certain chemical reaction
Andrews [41]

Answer:

a) 120 possible experimental runs

b) 8 possible experimental runs

c) 0

Step-by-step explanation:

a. For the experiment, there are 6 different temperatures (T), 5 different pressures (P), and 4 different catalysts (C). We can find the total number of combinations using the product rule.

N = T × P × C

N = 6 × 5 × 4 = 120

b) If we use only the lowest temperature, we have T = 1, and if we use the two lowest pressures, we have P = 2. We can find the total number of combinations using the product rule.

N = T × P × C

N = 1 × 2 × 4 = 8

c) If we perform 5 experimental runs with 4 possible catalysts, it is not possible to use a different catalyst each time. At least, 1 catalyst must be repeated twice. Then, the event "a different catalyst is used on each run" has a probability of 0.

Graph the line y=-x+6
12345 [234]

To graph a line, first, we need to plot out values. Let’s find a few: if y is 2, -x would be 2-6, and x would be 4. If y is -2, x would be 8.

Now, all you have to do is put a few more of those points on a line graph and connect them.

Good luck!

Solve the question below, please
zhuklara [117]

Answer:

Step-by-step explanation:

(x-3)/(x+4) = x/(x+10)

(x-3)(x+10) = x(x+4)

x²+7x-30 = x²+4x

3x = 30

x = 10

How many pieces would it take to make 2 1/3
DENIUS [597]
It would take 3 pieces to make 2 1/3 because 2 and 1/3 is more than just 2 alone which would take another piece to get it to 2 1/3
