Answer:
a. 990 b. 243 c. 693
Step-by-step explanation:
a. 1,800 * 0.55 = 990
b. 1,800 * 0.45 = 810
810 * 0.3 = 243 pretzels
c. 1,800 * 0.55 = 990
990 * 0.7 = 693 croissants
Remember:
sec t=1/cos t
sin²t+cos²t=1 ⇒sin²t=1-cos² t
Therefore:
cos t(sec t- cost)=(cos t* sec t)- cos² t=(cos t * 1/cos t)-cos² t=1-cos²t=sin² t
Answer: cos t(sec t-cos t)=sin² t
Using the median concept, it is found that it would remain the same, as only the tallest student is replaced, which does not influence the median.
<h3>What is the median?</h3>
The median of a data-set is the value that <u>separates the bottom 50% from the upper 50% of values.</u>
Hence:
- In a data-set of 8 values, the median is the <u>mean between the 4th and the 5th elements</u>.
- Only the tallest student is replaced, which is the 8th element, hence not affecting the median, which remains the same.
