wait so do they delete their answers that they put for you or they delete your question?
Correct Answer:
Option B. It will have less variationThe standard deviation of distribution of sample means is given by:
Here,
s = Standard deviation of distribution of sample means
S = Population standard deviation
n = Sample Size
From equation we can see that Standard deviation of distribution of sample means is inversely proportional to the square root of sample size. This means if sample size is increased, the standard deviation of distribution of sample means will decrease. Hence a larger sample size will have less variation as compared to a small sample size.
Therefore, option B is the correct answer.
Answer:
1. 12cm.
2. 10cm.
3. 18cm.
4. 16cm.
5. 3cm. (or -3 if your question was negative.)
6. 36cm.
7. 8cm.
Explanation:
<em><u>To find the radius of a circle, simply divide the diameter by 2. </u></em>
With this being said we can just add on top of the given radius.
Example:
The given radius is 5cm. What is 5cm + 5cm? 10cm.
Thus, getting our answer.
Answer:
Angle 2 = Angle 4 = 76
Step-by-step explanation:
Here, we want to get the measures of angle 2 and angle 4
From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)
The reason for this is because both angles are same side interior angles
Thus,
angle 2 + angle 5 = 180
angle 2 = 180 - angle 5
angle 2 = 180 -104
angle 2 = 76
Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles
Thus, angle 2 = angle 4 = 76
