Answer: it will take 23 weeks for both of them to weigh the same.
Step-by-step explanation:
Let x represent the number of weeks that it will take both of them to weigh the same.
Let y represent the weight of Jose in x weeks.
Let z represent the weight of Marty in x weeks.
Jose weighs 180 pounds and plans on gaining 2 pounds per week. This means that
y = 180 + 2x - - - - - - - - 1
Marty weighs 249 pounds and plans on losing 1 pound per week. This means that
z = 249 - x - - - - - - - - 2
To determine the number of weeks that it will take both of them to weigh the same, we will equate both equations. It becomes
180 + 2x = 249 - x
2x + x = 249 - 180
3x = 69
x = 69/3 = 23
The answer is true, by definition, its true.
Answer:
Probability of getting raise when you get promoted = 0.625
Step-by-step explanation:
We have to find the probability of getting a raise. So,
Promotion = P, Raise = R
First we find if you get the promotion, what is the probability that you will also get a raise
Probability of getting raise when you get promoted = 0.625.
Now we find the probability of getting a raise,
So, the probability of getting raise = 0.57.
You just need to plug in the original price.
0.765(100)+0.06(.765(100)) = 81.09
The cost costs $81.09 for Chris.
