Suppose that $575.75 is invested in a savings account with an APR of 12% compounded monthly. What is the future value of the acc

SOVA2 [1]

Answer:

FV= $1,045.96

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $575.75

Number of periods (n)= 15*5= 60 months

Interest rate (i)= 0.12 / 12= 0.01

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 575.75*(1.01^60)

FV= $1,045.96

The mean life of a particular brand of light bulb is 1200 hours. If you know that at about 95% of this brand of bulbs will last

Pachacha [2.7K]

Answer:

c) 50

Step-by-step explanation:

We have been given that the mean life of a particular brand of light bulb is 1200 hours. About 95% of this brand of bulbs will last between 1100 and 1300 hours.

We will use z-score formula to solve our given problem.

$z=\frac{x-\mu}{\sigma}$ , where,

$z=\text{z-score}$ ,

$x=\text{Sample score}$ ,

$\mu=\text{Mean}$ ,

$\sigma=\text{Standard deviation}$

We know that 95% of data points lies within two standard deviation of mean, so 1100 will correspond to a z-score of -2 and 1300 will correspond to a z-score of 2.

$-2=\frac{1000-1200}{\sigma}$

$-2=\frac{-100}{\sigma}$

$\sigma=\frac{-100}{-2}$

$\sigma=50$

We can use sample score 1300 and get same answer as:

$2=\frac{1300-1200}{\sigma}$

$2=\frac{100}{\sigma}$

$\sigma=\frac{100}{2}$

$\sigma=50$

Therefore, the standard deviation of the light bulbs’ life is 50 years.

I need help with how to find 2 equations for thy problem

Mrrafil [7]

To know how to find the answer you these two equations you figure out what the line is solid or dash.
Then you find the slope y-int form for the first equation and repeat for the second.
For your equation it would be y > 2x+2 and the second equation would be y> or equal to -1x+0
