Answer:
30 000 tiles
Step-by-step explanation:
Firstly convert the dimensions into metres
Then find the total surface area for one tile...in its....;
T.Surface area = 2(0.225 × 0.1) + 2(0.1 × 0.075) + 2(0.225 × 0.075)
Total surface area of one tile = 0.09375m^2
Then divide it into the surface area that the paint can be applied to....
2812.50 ÷ 0.09375 = 30 000 tiles
Definitely the ones (A). Since its measured in feet the tallest person should be around 6 feet which does not pass 10.
LM = LN
3x - 2 = 2x + 1
x = 3
LM = LN = 7
MN = 5x - 2 = 13
Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
<h3>What is a confidence interval?</h3>
It is given by the sample statistic plus/minus the margin of error.
In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:
68% - 3.1% = 64.9%.
68% + 3.1% = 71.1%.
The 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
