I think it’s C because inverses are basically the reciprocals of each other. These make 90 degree angles and the slopes product should be -1. C looks like the lines are perpendicular so I would go with that

Answer:

Since we can see that they are vertically opposite angles

so 33° = 2x +1°

2x =33°+1°

2x = 34°

Therefore x= 17°

A true-false quiz with 10 questions was given to a statistics class. Following is the probability distribution for the score of

mart [117]

Solution

Question 1:

- The formula for finding the mean score is that of the expected value formula. That is,

$\begin{gathered} E(x)=\sum_{i=1}p_i\times x_i \\ where, \\ p=\text{ The probability of getting a score of }x\text{ } \\ x=\text{ The actual score} \end{gathered}$

- Thus, the mean can be gotten as follows:

$\begin{gathered} \sum px=5\left(0.06\right)+6\left(0.16\right)+7\left(0.34\right)+8\left(0.23\right)+9\left(0.15\right)+10(0.06) \\ =7.43 \end{gathered}$

The mean score is 7.43

Question 2:

- The more students write the exam, the more the mean score will approach the theoretical mean score.

- The theoretical mean score is calculated above to be 7.43

- Thus, as more students write the quiz, their scores approach 7.43

The domain is the whole set of x values, so the domain would go from -infinity to positive infinity. The vertex would be (-5,0) because that is the lowest point on the graph. The Range would include -5 and go up to infinity.
