Step-by-step explanation:
If you are reffering to this dot plot, it would be 13 trees being studied.
Answer D.
Explanation:
7(1-k) to solve that you have to multiply 7 for 1 and for -k
You get 7 - 7k
If you have to factorize 7-7k you do the GCD between 7 and 7k (it's 7!) and then divide 7 and -7k by 7
You get 7(1-k)

Answer:
Step-by-step explanation:
Required to prove that:
Sin θ(Sec θ + Cosec θ)= tan θ+1
Steps:
Recall sec θ= 1/cos θ and cosec θ=1/sin θ
Substitution into the Left Hand Side gives:
Sin θ(Sec θ + Cosec θ)
= Sin θ(1/cos θ + 1/sinθ )
Expanding the Brackets
=sinθ/cos θ + sinθ/sinθ
=tanθ+1 which is the Right Hand Side as required.
Note that from trigonometry sinθ/cosθ = tan θ
