Answer:
Null and alternative hypotheses:
H0: p1 = p2
H1: p1 ≠ p2
To find the sample proportions, we have the following:
Calculate Z statistics:
Z = -2.764
P-value = 0.00285
The pvalue is low.
Since the pvalue is low, reject null hypothesis, H0.
Conclusion:
There is strong evidence that patients experiencing the primary outcome is different for those receiving the treatment compared to those without
You can solve this problem by using the pythagorean theorem.
Where the a- and b-values represent the sides of the triangle. Since the park is a sqaure, each side is equal. This means that both the a-value and the b-value are the same. Now, you must find the c-value.
145^2 + 145^2 = c^2
21,025 + 21,025 = c^2
42,050 = c^2 *now square root each side of the equation.*
205.06 = c
The length of the diagonal line is 205 meters.
Answer:
For any method or algorithm, there will always be changes, as there are many ways to create on request, and one method might be better than the other.
I discovered that direct instruction is important by designing my own algorithm.
It is the use of simple, direct teaching methods, usually in order to teach a particular skill.
Answer:
Yes
Step-by-step explanation:
To form a triangle : The sum of any two side lengths must be bigger than then the third side length and their difference smaller than the third side length.
19.6 + 1.6 > 18.7
19.6 - 1.6 < 18.7 and so on.
Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
