Answer:
4 1/2 hours.
Step-by-step explanation:
If 1/2 an hour only used up 1/9 of her battery, 9, 1/2 would give us 9/2, which if you simplified it gets you 8 1/2 hours. Hope this helps! Have a great day!
Answer:
Probability Distribution
Step-by-step explanation:
Probability Distribution determines the possibility that an outcome will occur in a random experiment.
The probability of a certain event is 1 and that of event that will never occur is 0.
The sum total of all probabilities of all outcomes in a random experiment is 1.
There are different types of probability distribution , namely: normal distribution, poison distribution, chi square distribution etc.
The distribution types are required for different purposes. For example, normal distribution estimates the probabilities of an outcome occuring for a given number of trials given the probability of each event in each trial.
Answer: D
<u>Step-by-step explanation:</u>
Vertex form is: f(x) = a(x - h)² + k where (h, k) is the vertex.
f(x) = (x - 3)² - 5
- the vertex is (3, 5).
- "a" is positive (+1), so it points upward.
The only graph that matches is the last one, <em>which I called graph D.</em>
- Find the y-intercept
- Find the roots (i.e. x - intercepts)
- Determine where the function increases and where it increases, along with the maximum and minimum values.
- Determine where the function changes concavity along with the inflection points.
- Determine the special points, where the value of the function is not defined and try to find the limit when the value of x approachs to this values
- Determine the limits of the function when x approachs to positive infinity and negative infinity
- For some of those steps you need to know some concepts of calculus: limits and derivatives along with the rules that let you know if a point is a maximum, a minimum or an inflection point.
With that information you can sketch a polynomial function.
It looks like your question is incomplete. I believe you also have options to pick which graph is correct. However, I can still give you the information you are looking for.
The slope of the line is -1.2
The Y-intersect is (0, 4)
I have also attached an image of what the graph would look like.
Hope this helps.
