A very large study showed that aspirin reduced the rate of heart attacks by 44%.
we claim that they have a drug that will be more effective than aspirin.
so, our hypothesis would be
So, it will be one tail test.
Hence,
Answer:
9 servings of meat.
Step-by-step explanation:
The first ratio you are given is 8:36. You are trying to figure out what 2:__ is.
8/36 x 2/X

Answer:
The numbers are 11 and 49.
Step-by-step explanation:
<em>x = 5y - 6 </em> This is just the first sentence written as an equation.
<em>x + y = 60</em> This is just the second sentence written as an equation.
<em>5y - 6 + y = 60</em> Substitute x for what you know it is equal to
<em>6y - 6 = 60</em> Collect like terms
<em>6y = 66</em> Add 6 to each side
<em>y = 11</em> Divide each side by 6
<em>x = 5 × 11 - 6 </em> Substitute y for what you know it is
<em>x = 55 - 6</em> Simplify by working out 5 × 11 = 55
<em>x = 49</em> Subtract 6 from 55 to get 49
