30 minutes
Step-by-step explanation:
talking to her relatives during the month.
Step-by-step explanation:
648/18
18/64=3 remaining 10
bring 8 down making 108
108/18=12
3 and 12=312
ans =312
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the following Product to Sum Identities:
2 sin A sin B = cos (A - B) - cos (A + B)
2 sin A cos B = sin (A + B) + sin (A - B)
Use the Unit Circle to evaluate: cos 120 = -1/2 & sin 60 = √3/2
<u>Proof LHS → RHS</u>
LHS: sin 20 · sin 40 · sin 80
Regroup: (1/2) sin 20 · 2 sin 40 · sin 80
Product to Sum Identity: (1/2) sin 20 [cos(80-40) - cos (80+40)]
Simplify: (1/2) sin 20 [cos 40 - cos 120]
Unit Circle: (1/2) sin 20 [cos 40 + (1/2)]
Distribute: (1/2) sin 20 cos 40 + (1/4) sin 20
Product to Sum Identity: (1/4)[sin(20 + 40) + sin (20 - 40)] + (1/4) sin 20
Simplify: (1/4)[sin 60 + sin (-20)] + (1/4) sin 20
= (1/4)[sin 60 - sin 20] + (1/4) sin 20
Unit Circle: (1/4)[(√3/2) - sin 20] + (1/4) sin 20
Distribute: (√3/8) - (1/4) sin 20 + (1/4) sin 20
Simplify: √3/8
LHS = RHS: √3/8 = √3/8
I helped you on the other one. You can never use data to say for certain so that rules out the first and third options. Because sample B's IQR is further to the right, that one is likely to grow taller...
Therefore the answer is Corn grown with PG86 will likely grow taller than corn grown without PF86.
