Y=6x-11
-2x-3y=-7
Take "6x-11" and insert it where it says 3y. Now you have:
-2x-3(6x-11)=-7
Use distributive property (-3 × 6x) ( -3 × -11). Now you have:
-2x-18x+33=-7
Combine like terms. (-2x + -18x). Now you have:
-20x+33=-7
Subtract 33 from both sides (33-33 and -7-33). Now you have:
-20x=-40
Divide -20 from both sides (-20x/20 and -40/-20). Now you have:
Answer: x= 2
The answers is 2.8 and or 2.83 which ever your answer chose is
Answer:
<u>Question 1: </u>
1. It is 95% certain that the true mean lies in the interval 16-36 years.
- Based on this sample, we are 95% confident that we captured the true mean in our sample. Not sure why the interval is wrong, though--it should be between 21-31 years (26 - 5, 26 + 5).
<u>Question 2: </u>
3. We are 95% confident that the true mean lies somewhere within 168-208 ng/ml.
- Again, the boundaries are wrong. THey should be between 178 and 198 ng/mL, but the rest of the sentence is correct.
<u>Question 3: </u>
2. Measures how far the sample mean is likely to be from the population mean
1. Can be calculated using the standard deviation of the population and the size of the sample
- The standard error is an approximation of the standard deviation that we use when we're not sure of the stdev or all the data values. Its purpose is to figure out how far the means were from each other, and approximate how far off our results were.
Answer:
Step-by-step explanation:
Let 
be the expression for the linear function k(x), where m is the slope of the function and this function passes through the point (1,8).
Thus, 
and the function expression is
If the graph of the function passes through the point (1,8), then its coordinates satisfy the function expression. Substitute them:
Hence,
The graph of this function intersects the x-axis at k(x)=0, then
Zero of the function is x=3
