∠O = 50°
Step-by-step explanation:
Opposite angles of an isosceles trapezoid are supplementary.

... ∠O = 180° - ∠T = 180° -130° = 50°
Answer: 0.0129
Step-by-step explanation:
Given : Sample size : n=32
The average amount of time spent texting over a one-month period is :
Standard deviation :
We assume that the time spent texting over a one-month period is normally distributed.
z-score :
For x= 199
Now by using standard normal table, the probability that the average amount of time spent using text messages is more than 199 minutes will be :-
Hence, the required probability = 0.0129
