Answer:
4 km
Step-by-step explanation:
1000m:3m = 4000m:12m
Given table:
color ----- Frequency
Red ------ 14
Green ----- 19
Blue -------- 21
Yellow ----- 16
Number of process repeated (trials) = 70 times
Probability (event) = number of times the event occurs / total number of trials
From the table we can see that the number of times she pick the blue marble is 21
Probability of picking a blue marble on next try =
= 
The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.
2a^2b^3*4a^2 = 8a^4b^3
D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
By hypothesis, each minute of local calls costs $0.05
So x minutes of local calls will cost 0.05x : You just multiply the cost of 1 minute by the total amount of minutes.
Same thing for long distances calls: Each minute costs $0.12, so y minutes of long distance calls will cost 0.12x
So to get your total charge (local calls + long distance calls), you just need to add the charges for local calls with the charges for long distance calls, which means that you need to add the expressions we got previously:
P = 0.05x + 0.12y (with P the total charge)
Hope this Helps! :)
Answer:
They are the same because they have the same slope but are different because they have different y intercepts.
