Answer:
Information is missing on the price of electricity.
Step-by-step explanation:
There is information missing on the cost of the electricity, per kwh. b(x) = ????.
If it is $0.20/kwh, then we would have:
b(x) = $0.20x
b(800) = $0.20*(800)
b(800) = $160
It depends on the price.
Answer: last option
Step-by-step explanation:
The formula to find the Discriminant is:
Given the quadratic equation 
, you can identify that:
Now, you can substitute values into the formula , then:
As the Discriminant is greater than 0 (
), then the quadratic equation has two distinct real solutions.
Answer:
See below
Step-by-step explanation:
A 90% confidence interval is centered at a parameter and is 90% sure to contain the statistic.
When you are running a statistical test, you can create a confidence interval centered at the appropriate parameter (such as the mean) to see if the statistic stated in your null hypothesis is true if it's contained in the interval. Whatever the confidence level is determines how wide the interval will be, and as such, will determine how likely the interval will catch the statistic in question.
329 :32=10,28125 is the answer
6 minutes, 3 minutes, 5 minutes
we need to find the lowest common multiple of these numbers.
6 : 6,12,18,24,30
3: 3,6,9,12,15,18,21,24,27,30
5: 5,10,15,20,25,30
30 is ur lowest common multiple...so they will all meet at the starting point in 30 minutes...hooray for piggly, piglet, and wiggly :)
