A gift of 6000 to a city grew to 4000000 in 200 years. At what interest rate compounded annually would this growth occur

guapka [62]

4000000/6000=666.67
(1+r)^200=666.67
ln (1+r)^200=ln 666.67
200 ln (1+r)=ln 666.67
e^ln (1+r)=e^.03251145
1+r=1.0330457
r=0.0330457, or 3.30457% APR

Find all unique zeros of the function fix) 8x- 64x + 160x- 128-

LenKa [72]

Answer: Lets divide by 8. My god, those coefficients are large.

x^3 - 8x^2 + 20x - 16 = 0

Possible integral roots are: +1, -1, +2, -2, +4, -4, +8, -8

If x = 2, f(x) = 8 - 32 + 40 - 16 = 0

Hence, x-2 is a factor.

Use synthetic division to get: x^2 - 6x + 8 = (x-4)(x-2).

Therefore, there are two integral roots: +2 and +4.

Which of the following is true for a median? Medians are affected by outliers. Medians can be calculated no matter how the data

Lady bird [3.3K]

Answer:

Option D) is true about median

Step-by-step explanation:

We are given the following information in the question:

Median:

The median is the middle number or the center of the data when the data is sorted in either ascending or descending order.

The median is not affected by the presence of any outliers since the data is sorted.

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Option A) Medians are not affected by the outliers

Option B) Medians can only be calculated when the data is sorted.

Option C) This is a false statement about the medians.

Option D) True

When there are even number of observations, the median is the mean of the two middle numbers.
