The considerations that  was relevant to the IRB's determination that this activity does not constitute research with human subjects is "<span>The researcher will not be interacting/intervening with subjects and the data has no identifiers".

</span>
Generally, any human subjects inquire about that is directed by VDH, by outside examiners in a joint effort with VDH, or by outside agents utilizing VDH information, is liable to survey and endorsement by the VDH Institutional Review Board. However, not all examinations require IRB review.

Yakvenalex [24]

Answer:

Yard Tools manufactures lawnmowers, weed-trimmers, and chainsaws. Its sales mix and unit contribution margin are as follows.
Firlakuza [10]

Answer:

Lawnmowers= 45,726

Weed-trimmers= 114,314

Chainsaws= 68,589

Explanation:

Giving the following information:

Sales Mix - Unit Contribution Margin

Lawnmowers 20 % $34

Weed-trimmers 50 % $24

Chainsaws 30 % $37

Yard total has fixed cost of $6,836,000

Based on the weighted average sales participation and the unit contribution margin, we can calculate the weighted average contribution margin for the whole company. We need it to calculate the break-even point in units.

Break-even point (units)= Total fixed costs / (weighted average selling price - weighted average variable expense)

Weighted average contribution margin= sales participation per product* unitary contribution margin

Weighted average contribution margin= (0.20*34) + (0.5*24) + (0.3*37)= 29.9

Break-even point (units)= 6,836,000/ 29.9= 228,629 units

<u>Now, we can calculate the required units for each product:</u>

Lawnmowers= 0.20*228,629= 45,726

Weed-trimmers= 0.50*228,629= 114,314

Chainsaws= 0.3*228,629= 68,589

Inga invested part of her $6000 savings in common stock and the rest in rare stamps. At the end of the year, she realized a gain
kherson [118]

Answer:

The amount Inga invested in stamps is $2,500.

Explanation:

Let x represents the amount invested in common stock. Therefore, we have:

Amount invested in common stock = x

Amount invested in stamps = 6000 - x

Rc = Rate of gain from common stock = 9%, or 0.09

Rs = Rate of gain from common stock = 12%, or 0.12

Amount of saving now = $6615

Therefore, we have

Amount of saving now = (x * (1 + Rc)) + ((6000 - x) * (1 + Rs)) ………….. (1)

Substituting all the relevant values into equation (1) and then solve for x, we have:

6615= (x * (1 + 0.09)) + ((6000 - x) * (1 + 0.12))

6615 = (x * 1.09) + ((6000 - x) * 1.12)

6615 = 1.09x + (6720 - 1.12x)

6615 = 1.09x + 6720 - 1.12x

6615 - 6720 = 1.09x - 1.12x

-105 = -0.03x

x = -105/-0.03

x = 3,500

Therefore, we have:

Amount invested in stamps = 6000 - x = $6,000 - $3,500 = $2,500

Therefore, the amount Inga invested in stamps is $2,500.
