An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously. How much was deposited
Leya [2.2K]

The intital amount deposited was  $18485.82.

<h3>How to find the compound interest?</h3>

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

a = p(1 + \dfrac{r}{n})^{nt}

An account has $26,000 after 15 years. The account received 2.3 percent interest compounded continuously.

A = 26000

R = 0.02.3

a = p(1 + \dfrac{r}{n})^{nt}

26000 = p(1 + \dfrac{2.3}{100})^{15}\\\\26000 = p \times 1.4064\\\\\P= 18485.82

Therefore, the intital amount deposited was  $18485.82.

suppose the mean 40 yard dash time of a perfessional football player is 4.41 seconds with a standard deviation of 0.15 seconds.
I am Lyosha [343]
The percent of runners between these two times is 47.72.

We find the z-scores associated with each end of this interval using the formula
z=(X-μ)/σ

For the lower end,
z=(4.11-4.41)/0.15 = -0.3/0.15 = -2

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this score is 0.0228.

For the upper end:
z=(4.41-4.41)/0.15 = 0/0.15 = 0

Using a z-table we see that the area to the left of, less than, this score is 0.5000.

We want the area between these times, so we subtract:
0.5000-0.0228 = 0.4772

This corresponds with 47.72%.

A line has a slope of -1/2 and a y-intercept of –2. So what is the x intercept on the line.
SashulF [63]

Answer:

(4,0)

Step-by-step explanation:

The equation of the line is y = (-1/2)x - 2.  At the x-intercept, y = 0. Setting y = (-1/2)x - 2 to zero, we get (1/2)x = 2, and thus x = 4.
