Answers

Answer 1

The best phrase that describes T helper 1 (TH1) cells is activate cell-mediated immunity and phagocytic cells resulting in delayed hypersensitivity reactions.

What is the role of T cell?

Th1 cells produce cytokines mainly related to phagocytosis-mediated defense against intracellular infectious agents, such as Interferon-gamma (INF-γ), IL-2 and Tumor Necrosis Factor alpha (TNF-α).

The T helper cells (Th cells) are a type of T cell that play an important role in the immune system, particularly in the adaptive immune system. They help the activity of other immune cells by releasing T cell cytokines.

(1) Compute the total variable cost per unit. (2) Compute the total fixed costs. (3) Compute the income from operations for sales volume of 16,000 units. (4) Compute the income from operations for sales volume of 20,000 units.

Answers

The Total Variable Cost per unit is given as:= $115 per unit

What is Total Variable Cost?

The total variable cost is the sum of all variable costs associated with each individual product that has been produced.

It is computed by multiplying the cost to make one unit of your product by the number of products was produced.

Hence:

Total Variable cost per unit = Direct materials  +Direct labor + Production supplies + Sales commission + Packaging

TVC = ($450,000 / 18000) + (($756,000 /18000) + ($486,000 / 18000) + ($126,000 / 18000) + ($252,000 / 18000)

TVC = $25 + $42 + $27 + $7 + $14

TVC = $115 per unit

What is the total fixed cost?

Total fixed costs (TFC) is the total of all consistent, non-variable expenses a company must pay during the course of it's operations.

Hence,  

Total fixed costs (TFC)  = Plant manager salary + Advertising + Administrative salaries + Depreciation - Office equipment + Insurance + office rent

TFC = $250,000 + $100,000 + $300,000 + $270,000 + $240,000 + $250,000

TFC = $1,410,000

What is the income from operations for sales volume of 16,000 units?

The total income or revenue from 16,000 units is given as:

Contribution margin - Fixed costs

TI (16,000) = ($206 - $115) * 16000 - $1,410,000

TI = $46,000

What is the income from operations for sales volume of 20,000 units?

Drawing form the formula above,  we have:

Contribution margin - Fixed costs

TI = ($206 - $115) * 20000 - $1,410,000

TI = $410,000

Answers

Based on the fact that two dice were rolled together, the probability of getting a sum of 7 is 16.7%.

What is the probability of getting a sum of 7?

The first step is the find the possible combinations that will add up to seven.

These are:

(1, 6) (2, 5)(3, 4)(4, 3)(5, 2)(6, 1)

There are six combinations that could yield a sum of 7 when both die are rolled together.

The total combinations when two dice are rolled is:

= Number of sides on one cube x Number of sides on other cube

= 6 x 6

= 36

The probability of rolling a combination with a sum of 7 is:

= Number of combinations that add up to 7 / Total number of combinations
