Answer:
9/10
Step-by-step explanation:
You find the lowest common denominator which is 56 and then, you multiply each numerator by the opposite denominator (3 times 7 and 3 times 8) after that you should get 5 45/50 then you simplify it to get 9/10
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.
Answer:
n = -2
Step-by-step explanation:
-38 = -2n -12 +18n +6
-38 =16n -6
-38 +6 =16n
-32= 16n
n=-2
Answer:-9 :)
Step-by-step explanation:
Answer:
1. y = 32
2. x = 6
3. -33 = n
4. a = -15.6
Step-by-step explanation:
1.
y-23=55
+23 +23 (23 cancels)
y = 32
2.
x - 14 = -8
+14 +14 (-14 cancels)
x = 6
3.
-15 = n + 18
-18 -18 (18 cancels)
-33 = n
4.
18.3 + a = 2.7
-18.3 -18.3 (18.3 cancels)
a = -15.6
