A nursery has 10 tree seedlings to give out at 2 workshops. It wants to give out a minimum of 2 seedlings at each workshop. How

11111nata11111 [884]

We are given total 10 tree seedlings.

Number of workshops = 2.

Here order doesn't matters.

<em>When order doesn't matters we apply combination.</em>

We know formula of combination:

$C(n,r) = \frac{n!}{r!(n-r)!}$

For the given situation, we have

n=10 and r=2.

Plugging values in formula, we get

$\frac{10!}{2!(10-8)!} = \frac{10\times 9\times8!}{2!8!}$

$\frac{10 \times 9}{2} = \frac{90}{2} =45$

<h3>Therefore, 45 different ways can the nursery give out seedlings.</h3>

Step-by-step explanation:

cos θ = 3 / AB

When θ = 28°:

cos 28° = 3 / AB

AB = 3 / cos 28°

AB ≈ 3.4

When AB = 5.2:

cos θ = 3 / 5.2

θ = cos⁻¹(3 / 5.2)

θ ≈ 54.8°
