1) 6x^2 + 42x

2) x^2 − 7x − 30

3) x^2 + 9x +20

4) x^2 - 14x +48

5) 2x^2 +21x - 11

6) 5a^2 - 125

7) 8x^2 - 6x - 9

8) 4x^2y - 24xy + 32

( I never asked a question before so yeah idk what to say)

The random variable x is defined as the number marking the sector in which the arrow lands when the spinner in the diagram is spun once.

Now, martin can reasonably guess that the standard deviation for the entire population of people at the mall during the time of the survey is $1.50. what is the 95% confidence interval about the sample mean? interpret what this means in the context of the situation where 95 people were surveyed and the sample mean is $8. use the information in this resource to construct the confidence interval.

In physics, if a moving object has a starting position at so, an initial velocity of vo, and a constant acceleration a, the the position s at any time t> o is given by: s = 1/2 at ^2 + vot+so solve for the acceleration, a, in terms of the other variables. for this assessment item, you can use^to show exponent and type your answer in the answer box, or you may choose to write your answer on paper and upload it.
