First department can choose the pair (delegate,alternate) by 7*6 = 42 ways.
Second department can choose the pair (delegate,alternate) by 10*9 = 90 ways.
Third department can choose the pair (delegate,alternate) by 6*5 = 30 ways.
Since these selections are INDEPENDENT, the resulting choice can be done in 42*90*30=113400
You could round 77 to 80 and 65 to 70 and then add 70 and 80 and you will get 150
1. Yes
2. A-2x
Hope this helps also I did this question and got it correct
Answer:
y =74x
Step-by-step explanation:
A proportional relationship is represented by y = kx where x is the independent variable, or input, k is the constant of proportionality, and y is the dependent variable or output.
What do we do to the values in the row for x to get the values in the row of y?
It helps to have x = 1 in this table.
74 = (k)(1)
74 = k
The answer is 3x10^12 also can i get brainliest please??
