6 feet = 72 inches
1 inch = 2.54 centimeters
72 * 2.54 = 182.88 cm which equals
1.8288 meters

Answer:
x = 32
Step-by-step explanation:
=> (3x-4) + (3x-8) = 180° (Linear pair)
=> 6x - 12 = 180
=> 6x = 192
=> x = 192/6
Therefore <u>x = 32</u>
Answer:
Step-by-step explanation:
n = 400
Proportion p = 229/400= 0.5725
For 95% confidence interval we use Z value as 1.96
Std error = 0.025
margin of error = 1.96*0.025
Confidence interval 95% = 0.5725±Margin of error
= (0.524, 0.621)
b) When smiled x becomes 277
p = 0.6925
Std error = 0.023
Margin of error= 1.96*0.023
Confidence interval = (0.647, 0.738)
Smiling increases the chances of stopping since mean and conidence interval bounds are showing increasing trend.
