16. ∠2 = 53° because it is supplementary.
- You are given the measurement of ∠1, which is 128°. From the picture you can see that ∠1 and ∠2 combined equal 180° (they are supplementary angles).
- So to find ∠2, simply subtract 128° from 180°. The answer is 53°.
------------------------------------------------
17. 12° because it is vertical.
- Vertical angles, like 48° and 4x in the image, are always equal.
- So if 4x = 48°, then you can divide both sides to get x = 12°.
Unimodal generally means to have or involve one mode and bimodal means to have or involve two modes.
Box plots are used to display data using a rectangle whose vertical edges represent the quartiles.
<h3>(a) The annual salaries of both companies</h3>
From the box plots, we have the following highlights:
- The entry salary at Company A is less than company B
- The median salary at Company A is less than company B
- The highest salary at Company A is greater than company B
<h3>(b) The pros and cons</h3>
For Company A, we have:
There is an outlier in the distribution of company A;
This implies that employees in company A have the possibility of earning more
For Company B, we have:
The entry salary at company B is more than the entry salary of employees in company A

Answer:
We have for velocity of package v= 20 - 9.8t and for distance from the ground y = h + 20t - 4.9t2.
We have y = 0 and t = 18.0 s we have h = 4.9·182 - 20·18 = 1227.6 m.
Velocity at landing v = 20 - 9.8·18 = - 156.4 m/s
