I’m not very sure how to simplify the two bottom rows, can someone help me?

love history [14]

Answer:

The simplification is done below.

Step-by-step explanation:

$(\sin(\frac{\pi}{6})\cos(\frac{\pi}{4}) - \sin(\frac{\pi}{4})\cos(\frac{\pi}{6}))^{2}$

= $(\frac{1}{2} \times \frac{1}{\sqrt{2}} - \frac{1}{\sqrt{2}} \times \frac{\sqrt{3}}{2})^{2}$

= $((\frac{1}{2\sqrt{2}}) \times (1 - \sqrt{3}))^{2}$

= $0.125 \times (1 - (2 \times \sqrt{3}) +3)$

Abscicca of Point A = 2

Ordinate of Point B = -4

Point D = (-4,2)

laila [671]

Mean = 450 sec
standard deviation = 50 sec
450-50 =400
450+50=500

Between 400 sec and 500 sec means one deviation above and one deviation below the mean, and it is 68%.

68%=0.68
0.68*288= 195.84≈196

Answer is d) 196
