Answer:
Step-by-step explanation:
Given that Advandia is a drug used to treat diabetes, but it may cause an increase in heart attacks among a population already susceptible.
Sample size n =1`456
Sample proportion of persons having heart attack p1= 27/1456 = 0.0186
II sample
Size = 2895
p2 = sample proportion = 41/2895 = 0.0142
a) Not matched pair data but independent proportions
b)
Step 1: 
(right tailed test at 5% significance level)
Step 2: Test statistic z = 1.0995
Step 3: p value = 0.13567
Step 4: Since p >0.05 accept null hypothesis.
There is no evidence to suggest that there is a significant increase in the proportion of people who suffer heart attacks when using Avandia compared to other treatments.
Step 5:
Answer:
Recursive formulas give us two pieces of information:
The first term of the sequence
The pattern rule to get any term from the term that comes before it
So I think A.Pattern
Answer: 
Step-by-step explanation:
In the simple radical form there are no square root is remain to find.
Since, the given expression,
Since, we do not need to find further square root of 7.
Thus, the required radical form of is .
Answer:
the answer is the 3rd one
Step-by-step explanation:
i jusst took the test on edge
The area of a square is expressed as the length of the side to the power of two, A = s^2. We were given the area of the enlarged photo which is 256 in^2. Also, it was stated that the length of the enlarged photo is the length of the original photo plus ten inches. So, from these statements we can make an equation to solve for x which represents the length of the original photo.
A = s^2
where s = (x+10)
A = (x+10)^2 = 256
Solving for x,
x= 6 in.
The dimensions of the original photo is 6 x 6.
