Y = -sqrt(x-3)
the -sqrt reflects the graph over the x-axis. Then, the -3 within the sqrt will affect the graph horizontally, shifting it to the right 3 units. (Operations inside parentheses or under radicals do the opposite. That is, - means move right and + means move left, across the y- axis).
Answer:
False
Step-by-step explanation:
Steps in calculating confidence Interval are
- Calculate degree of freedom by subtracting 1 from sample size that is df=sample size -1
- find α by subtracting confidence interval level from 1 and divide by 2
- Use value ot α and df to determine t from t-distribution table. From table it can be seen that the value of t increases as value of df decreases
- Divide standard distribution by square root of sample size. As sample size decreases this value will increase
- Multiple step 3 by step 4. We can say, if sample size is decreased this value will increase.
- For lower end , subtract step 5 from sample mean and for upper end add step 5 to sample mean.
If sample size is decrased, step 3 and step 4 will increase. As a result result obtained from step 5 will also increase. Hence, confidence interval will increase if sample size is decreased
Answer:
The first table; <em>the first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 16, 8, 4, 2.</em>
Step-by-step explanation:
Exponential decay means that the graph or table is exponentially decreasing. Meaning, if you went from point 4 to 1, you would see an exponential increase. Other tables show other forms of functions, such as quadratic, or linear. To find out which rate it is decaying by, ask yourself, at 0, what is the y output? You can then divide the output of 0 by 1, and so on. If it is decaying at a consistent rate, then you know it is exponential. If you do not need to divide, but know it is decaying at a rate of two, it is linear. If it does not divide the first time smoothly, it is quadratic. It could also be a number of things.
I hope this helps you. We studied this quite a while ago, and I do not remember the equation at the tip of my tongue, and I do not want to give you wrong information. Have a great rest of your day!
