I have to go in like 2 minutes, so I won't be able to explain it in full detail, but I hope this helps. Have an amazing day :)
Hi there!
The two angles are alternate-interior angles, so:
∠A ≅ ∠B
6x + 18 = x + 93
Solve for x. Subtract x from both sides:
5x + 18 = 93
Subtract 18 from both sides:
5x = 75
Divide both sides by 5.
x = 75/5 = 15°
Now, solve for angle B by plugging in this value into the equation.
∠B = 15 + 93 = <u>108°</u>
Answer:
115 - 90 = 25
Step-by-step explanation:
115 - 90, which is equal to 25, is less than or equal to x!
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.
