Answer:
Step-by-step explanation:
Given that:
The null hypothesis:
The alternative hypothesis:
Suppose the number of samples n from the population is 16
The observed value x of the test statistics for testing the hypothesis for this study is x = 14
However, if the null hypothesis is true, then the distribution of the test statistics follows a binomial distribution which is expressed as:
bin(n=16, p = 0.5) distribution
The p-value for this test statistics can be computed as:
p-value = P(X ≥ 14)
p-value = 1 - P (X ≤ 13)
p-value =
p-value =
p-value = 0.00209
Answer:
Assuming the x-6 is under the square root sign, the value must be greater than 6 because you can not have 0 in the domain. That narrows it down to either B or C but since the denominator can not be anything less than 0, your answers will always be positive so that means the answer is Its domain is (6,∞)
The answer is B you are welcomeee
Answer: -50
Step-by-step explanation:
-x + 25 = 75
25 - 75 = x
x = -50
The process is to go step-by-step to isolate the y.
To do this, you basically run the order of operations in reverse.
In 5x+2y=10, the first thing to move away from the left side is 5x and you cancel it out by subtracting 5x from both sides:
5x+2y - 5x = 10 - 5x
The 5x's on the left cancel leaving you with:
2y = 10 - 5x
Side note: this is more commonly written as 2y = -5x+10, since we tend to write variable terms first.
Finally, to get the y fully by itself, you need to cancel the 2 that's multplied against it. To cancel multiplication, you need to divide:
The most important thing to remember here is that the 2 needs to divide into both terms on the right:
Finally, we simplify this into:
