20 is the answer
I hope this help
Answer:
Part (a)
36
Part (b)
Find the filled table in the attachment
Part (c)
1/36
Step-by-step explanation:
The total number of possible outcomes using the multiplicative rule is given by;
6*6 = 36.
There are 6 possible outcomes in rolling each die, we simply find the product.
The probability of rolling double sixes is given by;
pr(6 and 6) = pr(6) * pr(6) = 1/6 * 1/6 = 1/36
The probability of rolling double sixes represents independent events and thus we employ the multiplicative rule of probability.
You didn't include the costs of doing repairs at both computer repair firms. I fixed that for you.
ABC Tech ------- $20 service charge plus $15 per hour.
Tech squad ------- $30 service charge plus $10 per hour.
Answer:
Steven's estimate of the repair time is 2 hours.
Step-by-step explanation:
Now in this case, we were told that ABC Tech normally charges $20 service charge and $15 per hour of computer repair service. The second tech firm charges $30 service charge and $10 per hour for computer repair service. We are now simply required to find out or calculate the number of hours of computer repair service whereby the cost of doing repairs at both tech firms become equal.
Let us use "x" to represent that unknown number of hours. The equation needed to calculate this is:
20 + 15x = 30 + 10x
We then pair like terms
15x - 10x = 30 - 20
5x = 10
x = 10/5
x = 2
Therefore the number of hours of computer repair service whereby the cost of doing repairs at both tech firms become equal is 2 hours.
