You have to turn 65 into a decimal. That would be .65
They do 39/.65
You should get 60 as your final answer.
The answer for the graph would be C. While x is less than or equal to 0, there is the graph of -4x. While x is greater than x, there is the graph of -5 (horizontal line). Furthermore, the closed dot at the end of the -4x represents the less than or EQUAL TO. The dot at the end of the -5 is open because it is only true when x > 0.
The range (y-values where the graph exists) is [-5]∪[0, infinity)
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](https://tex.z-dn.net/?f=%5Cfrac%7B%2836.2%20%2B%2029.0%20%2B%2046.2%20%2B%2037.5%20%2B%2040.9%20%2B%2040.0%20%2B%2032.6%20%2B%2040.5%20%2B%2040.1%20%2B%20x%29%7D%7B10%7D%20%3D%2038.0%5C%5C%5C%5C%5Cfrac%7B343%20%2B%20x%7D%7B10%7D%20%20%3D%2038%5C%5C%5C%5Cx%20%20%3D%20380%20-%20343%5C%5C%5C%5Cx%20%3D%2037)
x = 37%
<u>Second step - Survival rate</u>
The survival rate is calculated by;
= 1 - rate of loss
= 1 - 37%
= 63%
You got the b part wrong. It would be 4B+4C/2=4D
Answer:
$12,958
Step-by-step explanation:
The total amount of the account, principal plus interest, is given by ...
A = P(1 +rt)
The given information tells us ...
12,122 = P(1 + .08×2) = 1.16P
Then the principal amount is ...
12,122/1.16 = 10,450
__
When that same amount is invested using a different rate and time period, it becomes ...
A = 10,450(1 + .09×(2 2/3)) = 10,450×1.24 = 12,958
It will amount to $12,958 in 2 years 8 months at 9%.
