Answer:
decrease
Step-by-step explanation:
Given that the sample statistics gathered would not change very much for the new sample
When it is decided to take a larger sample, we find that automatically the margin of error decreases and hence confidence interval will become narrower.
When confidence level decreases then critical value decreases and hence margin of error decreases thus resulting in to decrease the confidence level,
Hence width would decrease.
i) Because of a larger sample size
ii) BEcause of decrease in confidence level.
Answer:
The correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by 
Option D is correct option.
Step-by-step explanation:
The circumference of table top = 24 inches
We need to find area of table top
The formula used to find area is: 
We need to find radius of tabletop.
The formula used to find circumference is: 
Putting value of circumference we can find radius
So, radius of table top = 12
Now, finding the area:
So, the correct option which best describes this method is:
Find half of 24 to calculate the radius. Then square the radius and multiply the result by
Option D is correct option.
Answer:
42=2×15+12
Step-by-step explanation:
2×15=30
therefore 30+12=42

Answer:
7/12
Step-by-step explanation:
To subtract fractions, you must make all of the fractions have a common denominator. We can set both of the denominators as 12. To achieve this, you must multiply both sides of 2/3 by 4. This will change the denominator of the fraction, while keeping the fraction equal to 2/3. Doing this will give us 8/12. Now we can subtract. Since the denominators are the same, we only subtract the numerators. Since 8-1 is 7, our answer is 7/12. The denominator does not change.
