Answer:
C
Step-by-step explanation:
Using the pythagorean theorem, we can determine if these are right triangles or not.
equation: sqrt a^2+b^2=c
this means the square root of the two shortest sides squared must equal to the largest side, (the hypotenuese).
Work for C:
Squareroot of 32^2 + 24^2 = 40cm
Answer:
C- There is a 3.8% chance that natural sampling variation could produce poll results at least as far below 54% as these if there is really no change in public opinion.
Step-by-step explanation:
The p-value indicates the probability that the test statistic occurs, given that the parameters of the null hypothesis are true.
The smallest the p-value, the less likely is the sample statistic obtained. If this p-value is below a threshold, called "level of significance", it can be claimed that the null hypothesis is wrong.
In this case, we can not say anything about the probability of success of the ad campaign or the quality of the poll, because we have no information about it.
It’s figure B it’s the same as figure 1
Answer:
I don't know, I'm so sorry but can you respond at my question?
Answer:
1/20 or 0.05
Step-by-step explanation:
Assuming that all five posters are different, the number of ways to randomly place those posters is given by:
If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:
Therefore, the probability is:
The probability is 1/20 or 0.05.
