Answer:
Reflection
Step-by-step explanation:
Reflecting it across the origin will give you the other one.
Answer:
0.0224 or 2.24%
Step-by-step explanation:
The probability that an intern uses drugs, given that the test is negative, is determined by the probability of false negative divided by the probability of a negative (true or false).
A false negative occurs when an intern who uses drugs (10%) takes the test and gets a negative. Since the test gets it right 80% of the time, the probability of this happening is:
A true negative occurs when an intern who does not use drugs (90%) takes the test and gets a negative. Since the test gets it wrong 3% of the time, the probability of this happening is:
Therefore, the probability that an intern uses drugs, given that the test is negative is:
The probability is 0.0224 or 2.24%.
Answer:
Inferential statistics
Step-by-step explanation:
When we conduct a poll, we aim to make a generalization about the population or units under study. The recent poll of 1971 home owners in West Virginia showed that the average (mean) price of house <em>in the U.S</em><em>.</em> is $319,000.
Recall that this poll was conducted only in West Virginia but the result or finding of the poll is being generalized over the U.S. as a whole. Hence, we are using the sample (fraction) to determine the population (whole) of home owners in the U.S. This is what we call <em>statistical inference or inferential statistics.</em>
Answer: 11
Step-by-step explanation: 2x^5 + 4x^4 – x^3 - x^2 + 7= 11
2x^2 - 1= 1
2x^5 + 4x^4 – x^3 - x^2 + 7 is divided by 2x^2 - 1.=11
11=-16 + y
-y -y ~1:subtract y from both sides
---------------
-y + 11=-16 ~this should be your equation
-11= -11 ~2: subtract 11 from both sides
----------------
y= -27
or if there is an x next to the 16 then the answer is y=-16x - 11
