Hie!! I will be solving the questions in the sequence of the attachments.

4. As line SU and TV are intersecting each other at O.
A.T.Q, ∠UOV = (7x - 4)°
∠SOT = 87°
Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

5. radius = 17ft
circumference of circle = 2πr

3. ∠1 and ∠2 - add to 180 (linear pair)
∠1 and ∠3 - equal (Vertically Opposite Angles)
∠3 and ∠4 - add to 180 (linear pair)
∠2 and ∠4 - equal (Vertically Opposite Angles)

2. 160° + (6x - 16)° = 180° (linear pair)
The bottom right.
The line best fit is usually the line that follows the trend of dots in the scatter plot. In the other 3, you can tell that there seems to be no trend between either the line or the dots.
The bottom right one has a line pretty much right through the middle of the scattered dots and follows the trend.
Answer:
The probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
Step-by-step explanation:
Let <em>X</em> = number of adults who use smartphones in meetings or classes.
The probability of the random variable <em>X</em> is, P(X) = <em>p</em> = 0.42
A sample of <em>n</em> = 5 adult smartphone users are selected.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The probability mass function of <em>X</em> is:
Compute the value of P (X = 2) as follows:
Thus, the probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
