Answer: Option b.
Step-by-step explanation:
1. You have the following parent function given in the problem above:
f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)
2. If you take the parent function and make y=f(x+3), then you have:
(The function is shifted 3 units left on the x-axis).
3. Then you if you make y=f(x+3)-2, as following, you obtain:
(The function is shifted 2 units down on the y-axis).
4. Therefore, that is how you obtain the final function.
The answer is the graph shown in the option b.
Answer:
Step-by-step explanation:
a. Given the mean is 28 and the standard deviation is 2.4
-Let X be the score of any random selection from the population.
-The probability that a randomly selected score is greater than 30.4:
Hence, the probability that the score is greater than 30.4 is 0.1587
b. The probability that a randomly selected score is less than 32.8 given mean =28 and the standard deviation is 2.4:
Hence, the probability that a random score is less than 32.8 is 0.9773
c. The probability that a random selection has a score of between 25.6 and 32.8.
-Given the mean=28 and sd=2.4, the probability is calculated as follows:
Hence, the probability that a random selection has a score between 25.6 and 32.8 is 0.8186
