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.
Let x be the lowest positive number Then the other number = 5x.
So 5x - x = 72
4x = 72
x = 18
So the numbers are 18 and 90 answer
The answer is to this question is c (5,-7)
Slope = (-3+4)/(0+5) = 1/5
passing (-2,2)
y = mx +b
2 = 1/5(-2) + b
2 = -2/5 + b
so b = 2 +2/5 = 12/5
equation
y = 1/5x + 12/5
answer is B y = 1/5x + 12/5
Answer:
1. 6.4 meters of streamers left to make pompoms
2. He will be able to make 8 pompoms
Step-by-step explanation:
1.
4 x 1.6 = 5.6 meters were used to make decorations.
Then we do 12 - 5.6 = 6.4
2.
per one pompom it takes 0.8 meters of streamers.
6.4 is the left over so we do
6.4 divided by 0.8 = 8 pompoms you can make
