I remember this from somewhere.
Answer:
E. Each trial is independent
Step-by-step explanation:
I'm not completely sure why all binomial distribution trials are independent, but there are requirements for binomial distributions.
These requirements are:
- Each outcome is either a success (p) or a failure (Q)
- All trials are independent
- There are a fixed number of "n" trials
- The probability of success (p) is the same for each trial
I also just took the test and got this right.
Answer: 6
Step-by-step explanation:
X = oranges / y = apples
x - 2 = 2y and 0.5x - 0.5y = 4
x - 2 = 2y
+2 +2
x = 2y + 2
0.5x - 0.5y = 4
2(0.5x - 0.5y = 4)
x - y = 8
Substitute
(x) - y = 8
(2y + 2) - y = 8
3y + 2 = 8
- 2 -2
3y = 6
y = 2
Substitute again
x = 2y + 2
x = 2(2) + 2
x = 4 + 2
x = 6
Hope this helps!
X + 7 = -6/3
x + 7 = -2
x = -2 - 7
Answer: x = -9
0.43 converted into a fraction should be 43/100
I found the missing choices:
<span>the standard deviation
the margin of error
the variance
the population mean
</span>
<span>The absolute difference between either limit and the mean is an example of THE VARIANCE.
Variance is defined as the</span><span> average of the </span>squared<span> differences from the Mean. </span>
