Answer:
The significance of the sample is that at it is statistically significant at 0.01 level ( i.e. of observing the sample < 0.01 )
Step-by-step explanation:
The sample observation which is 121 mothers that take vitamin supplements have male babies with mean weight of : 3.67 kg
while the National average birth weight = 3.39 kg
probability of observing such a sample = 0.0015
Hence the significance of the sample is that at it is statistically significant at 0.01 level ( i.e. of observing the sample < 0.01 )
Answer:
I believe F.) 9 is the correct answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that lines 
and 
are parallel, that means that we can establish some basic angle relationships here.
Since both lines are cut by a transversal, that means all angles formed by that line will be equivalent.
and 
are going to be equivalent because they are alternate exterior angles. These are formed by two parallel lines being cut by a transversal, and they will always be equal.
Since we know that both angles are equivalent to each other, we can set the expressions equal to each other to find x.
<em>Here's your equation, by the way.</em>
<em />
We can now solve for x.
Add 33 to both sides:
Subtract 2x from both sides:
Therefore, x = 59.

Answer:
26cm²
Step-by-step explanation:
Perimeter
2x - 4 + 5x - 13 + x + 9 = 40
8x - 8 = 40
8x = 40 - 8
8x = 32
x = 4
Sides of the triangle
Height = 2x - 4 = 2 x 4 - 4 = 4cm
Hypotenuse = 5x - 13 = 5 x 4 - 13 = 7cm
Base = x + 9 = 4 + 9 = 13cm
Area of triangle
= 1/2 x base x height
= 1/2 x 13 x 4
= 26cm²
