In a sales effectiveness seminar, a group of sales representatives tried a few approaches to selling a new automobile to a custo

Ksju [112]

Answer:

1. P(S) = 373/580

2. P(S|A) = 53/116

3. P(S|Pa) = 481/580

Step-by-step explanation:

Given

---------------------Sale ----- No Sale-----Total

Aggressive ----265 --------315 ----------580

Passive ----------481 ---------99 -----------580

Total --------------746---------414------------1160

A = aggressive approach,

Pa = passive approach,

S = sale,

N= no sale.

(a) Computing P(S)

This is calculated as the division of customers that participated in sales by total customers

Customers that participated in sales = 265 + 481 = 746

Total Customers = 1160

P(S) = 746/1160

P(S) = 373/580

P(S|A) means that the probability that a sales occur given that the aggressive method was used.

To solve this, we check the cell where Sales and Aggressive intersect

The cell element = 265

Total = 580

P(S|A) = 265/580

P(S|A) = 53/116

P(S|Pa) means that the probability that a sales occur given that the passive method was used.

To solve this, we check the cell where Sales and Passive intersect

The cell element = 481

Total = 580

P(S|Pa) = 481/580

The football team is selling hats to raise $425 for a trip they have $175 already if the team member sell the hats for $12 each

xz_007 [3.2K]

Answer:

The minimum number of hats which team need to sell t make enough money for the trip is 21 .

Step-by-step explanation:

Given as :

The money which team needs for the trip = $ 425

The money which team already = $ 175

So, The rest money which team need = $ 425 - $ 175 = $ 250

Now, The sell price for the hats = $ 12

Let The minimum number of hats which team need to sell = x

So, According to question

∵ The rest money which team need = $ 250

The selling price of each hats = $ 12

Or, The minimum number of hats which team need to sell = $\dfrac{\textrm Rest money which team needs}{\textrm The selling price of each hats}$

Or, x = $\frac{250}{12}$

∴ x = $\frac{250}{12}$

I.e x = 20.8

So, The minimum number of hats need to be sell = 20.8 ≈ 21

Hence The minimum number of hats which team need to sell t make enough money for the trip is 21 . Answer

How do you solve this

lys-0071 [83]

2x^2 + 14x = -12

Step 1: Subtract -12 from both sides.

2x^2 + 14x - (-12) = -12 - (-12)

2x^2 + 14x + 12 = 0

Step 2: Factor the left side of the equation.

2(x + 1)(x + 6) = 0

Step 3: Set Factors equal to 0.

x + 1 = 0 or x + 6 = 0

x = -1 or x = -6

Answer:
x = -1 or x = -6

Hope this helps. : )
