Answer: x= -(1/2)

Step-by-step explanation:

(x+5 +3) / x+3 = 3

Multiply both sides by (x+3)

(x+8)= 3(x+3)

x+8 = 3x+9

-2x = 1

x= -1/2

CHECK:

-1/2 +8 = 15/2 -1/2+3 =5/2

15/2 : 5/2 = 15/2*(2/5) = 30/10 = 3

What survival rate in the 10th year would make the average of loss over the 10 year period equal to 38.0%

Marat540 [252]

Answer: 63%

Step-by-step explanation:

<u>First step</u>

Find the 10th year rate of loss that will make the average of loss over the 10 years to equal 38.0%.

Assume this rate is x;

$\frac{(36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x)}{10} = 38.0\\\\\frac{343 + x}{10} = 38\\\\x = 380 - 343\\\\x = 37$

x = 37%

<u>Second step - Survival rate</u>

The survival rate is calculated by;

= 1 - rate of loss

= 1 - 37%

= 63%
