Idk what it has to do with simplifying but what I would do is multiply 1 times 3. That gives u 3. Then add Ben's one hour and Brooke's 3 hours together. That gives u 4 hours total.
110^76 is 110(add 76 more zeroes after the 0 in 110).
I hope this helps!(I do not want to spam the 0's, but for each 0 after 110 is adding 1 to the 110^.
Answer: Because we are trying to find the x-intercepts and the y-intercepts That would be (C)
Step-by-step explanation:
Self explanatory question, you set a quadratic equation to zero
For example: x 2 – 6 x = 16 equals to x 2 – 6 x – 16 = 0
Then, you would factor, that equals to (x – 8)( x + 2) = 0
(X-8)=0 (X+2)=0
X+2=0
-2 =-2
X=-2
X-8=0
+8 =+8
X=-8
To check you would simply plug in the values into the quadratic equation. They would both equal 16=16
:) Multiple choices are difficult but the best answers are C or D GO WITH YOUR GUT!
Answer:
[1,2], [2,1], [3,0]
Step-by-step explanation:
To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.
From our graph(attached) we multiply any three solutions by a -1:
Hence, the 3 solutions are [1,2],[2,1],[3,0]
Answer:
A. On average the blood pressure levels before the stress reduction program were significantly higher than the systolic blood pressure levels after the stress reduction program, at 95% confidence level
Step-by-step explanation:
The confidence interval parameters is intended to detect if the new stress reduction program will lower the systolic blood pressure levels of employees
The difference between the the mean systolic blood pressure levels taken = The before systolic pressure - The after systolic blood pressure
The 95% confidence interval obtained = (5.6, 10.2)
Therefore, given that the values of the difference between the means are both positive, then there a difference as the confidence interval does not include zero (0), and at the 95% confidence level, the average systolic blood pressure levels before the stress reduction program are higher than the average systolic blood pressure levels after the program
