Answer:
The probability that the counter was blue is
Step-by-step explanation:
Number of black Counters = 5
Number of blue Counters = 4
Number of white Counters = 1
We need to write down the probability that the counter was blue.
First find Total Counters
Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters
Total Counters = 5+4+1
Total Counters = 10
Now, we need to find probability that the counter taken was blue
The formula used is:
There are 4 blue counters in the back, so Favourable outcomes = 4
The probability that the counter was blue is
Question is Incomplete;Complete question is given below;
Arla and kal both work in jobs they get paid by the hour in their first week on the job they each worked 40 hours and together there total earnings were $1300 in their second week on the job business was slow so arla worked 20 hours and kal worked 16 hours their total pool earning was $580 what is each persons hourly wage.
Answer:
The hourly wage of Arla is $15 and hourly wage of Kal is $17.5.
Step-by-step explanation:
Let the hourly wage of Arla be
Also Let the hourly wage of Kal be
Now Given:
first week on the job they each worked 40 hours and together there total earnings were $1300
So we can say that;
⇒ equation 1
Also Given:
Number of hours worked by Arla in second week = 20
Number of hours worked by Kal in second week = 16
Total Money earned in second week = $580
So we can say that;
⇒ equation 2
Now Multiplying equation 2 by 2 we get;
Applying Distributive property we get;
⇒ equation 3
Now Subtracting equation 3 from equation 1 we get;
Now Dividing both side by 8 we get;
Now Substituting the value of y in equation 1 we get;
Hence The hourly wage of Arla is $15 and hourly wage of Kal is $17.5.
