Answer:
a.) 10 months
b.) Kool Karate
c.) Karate Klub
Step-by-step explanation:
Karate Klub : y=25x+200
Kool Karate : y=35x+100
A.) First, set the equations equal to each other then solve for x.
take away 100 from both sides
take away 25x from both sides
divide 10 from both sides so x can be by itself and equal to 1
This means that at 10 months, the cost is the same for both.
B.) Substitute 6 for x in both equations
Karate Klub :
Kool Karate :
The cost for Kool Karate is cheaper, so that is what he should join.
C.) Substitute 12 for x in both equations.
x=12 because there are 12 months in a year.
Karate Klub:
Kool Karate:
The cost for Karate Klub is cheaper, so that is what he should join.
Given:
The system of equation is,
-------- (1)
-------- (2)
To find the solution.
To solve the system of equation,
From (1) we get,
Putting this value into (2) we get,

or,
Hence,
The solution is and
I think the answer is
No
No
Yes
But I'm not sure about the last one
So u Line them up like the photo then you multiply 2 x 4 = 8 and multiply 3 x 1 = 3 so you get 8/3 then simply 8/3 the answer is 2 2/3
The sample statistic that must have changed after the correction was made is mean. Because mean is based on all the observation in the data. So changing any value in the data will impact mean.
Changing the highest salary in the data will have no impact on median because median lies at the center of data.
Changing the highest salary in the data will have no impact on mode because mode is the most frequently occurring value in the data.
Changing the highest salary in the data will have no impact on minimum because minimum is the smallest value in the data.
Hence the only statistic which will change is mean.
