You deposit $1000 into an account that pays interest compounded monthly. What interest rate do you need to double your money in 10 years? (as a percent, so change it back, write to two decimal places)
The interest rate required to double your money in 10 years with monthly compounding is approximately 133.27%.
How did we get the value?To calculate the interest rate required to double your money in 10 years with monthly compounding, you can use the formula:
rate = ( (2 * principal) / principal * (1 + n)^(t12) )^(1/t12) - 1
where
principal = $1000
t = 10 years
n = number of compounding periods per year (12 for monthly compounding)
Plugging in the values we get:
rate = ( (2 * 1000) / 1000 * (1 + 12)^(1012) )^(1/1012) - 1
rate = ( 2 * (1 + 12)^120 )^(1/120) - 1
rate = ( 2 * 169860981.54 )^(1/120) - 1
rate = 1.3327
So, the interest rate required to double your money in 10 years with monthly compounding is approximately 133.27%.

each of the following three data sets represents the iq scores of a random sample of adults. iq scores are known to have a mean and median of 100.
a) The mean of the sample of size 5 is equals to 103.
b) The mean of the sample of size 12 is equals to 103.3.
c) Median of sample of size 5 is 104.
d) Median sample of size 30 is 105.5.
Mean: Sum of observations is divided by number of observations in the sample is named as mean, which is denoted by X- bar. Moreover, the sample mean signifies the measure of centre of the data.
X-bar = (x₁ + x₂ + --- + xₙ)/n
Median: Median divides the observations into two equal parts. It represents the middle value for a set of observations when they are arranged in order of magnitude. There are two cases arises.
Case (1): Sample size (n) is odd: First, arrange the data in ascending order. Then, the median is the middle value and lies at the position.
Case (2): Sample size (n) is even: First, arrange the data in ascending order. Then, the median is the mean of the two data values that lie on either side of the position. Median = ( n/2)ᵗʰ term , n is odd
=[(( n/2)ᵗʰ term + (n/2 + 1)ᵗʰ term]/2, n is even
Now, a) Mean of first sample with sample size, n = 5.
Sum of values = 105 + 111 + 97 + 94 + 108 = 515
So, mean = 515/5 = 103
b) Sample 2, sample size , n = 12
Sum of values = 105 + 111 + 97 + 94 + 108 + 101 + 112 + 114 + 103+ 102+ 91 + 101
= 515 + 724 = 1239
Mean = 1239/12 = 103.25
c) Now, we have to determine median for sample size 5. Here, sample values are odd in number, i.e., 5. So, middle term is median after arranging in order. Ascending order is 94,97, 104, 108, 111 and middle term is 104, so median is 104.
d) Now, we have a sample of size 30, which is an even number. First arrange the numbers in ascending order as 91,92,92,94,95,97,100,101,101,101,101,102,103,105,105,105,106,107,107,108,110,111, 111, 112,113,114,115,115,116,116. So,
Median is [((n/2)th + (n/2 + 1)th ]/2 i.e, [ 30/2)th + 30/2 + 1)th ]/2
=( 15th + 16th)/2 ( observations)
= (105 + 106 )/2 = 211/2 = 105.5
Hence, the median of sample size 30 is 105.5.

What is linear function?In mathematics, a linear function is a function that expresses the relationship between two variables, x and y, in the form of y = mx + b, where m denotes the slope of the line and b the y-intercept. A linear function has a graph that is either a straight line passing through the origin if b = 0 or a point (0, b) if b 0.
A number of applications can benefit from linear functions because of their numerous beneficial characteristics. One of these characteristics is that they are always continuous, i.e., their graphs are seamless and devoid of gaps. They are the best candidates for simulating actual scenarios when two variables have a continuous relationship because of this characteristic.

The function is differentiable at these two x-values, the x-values at which the function is differentiable is (-1, 1/3).
The x-values at which the function is differentiable can be found by taking of the function and setting it equal to 0. The derivative of the function y = x3 + 2x2 - 5x + 8 is 3x2 + 4x - 5. Setting this equal to 0 and solving for x yields x = -1 and x = 1/3. So, the x-values at which the function is differentiable is (-1, 1/3).
In order to find the derivative of the function, the power rule was used. The power rule states that the derivative of a function f(x) = xn is f'(x) = nxn-1. Applying this to the function y = x3 + 2x2 - 5x + 8, the derivative is 3x2 + 4x - 5. Next, setting this equal to 0 and solving for x yields two solutions: x = -1 and x = 1/3.

If a model of the hexagon is made by using a scale factor of 6, which applies to the model? Select two options..
The effect of scaling on a hexagon by the scale factor of 6 is discussed above.
What is a hexagon?In geometry -
a hexagon is a six-sided polygon creating the outline of a cube. the total of the internal angles of any simple hexagon is 720°.Given is a model of the hexagon that is made by using a scale factor of 6.
If the initial length is equivalent to {a}. Then, after the scaling by the scale factor of {K}, the length becomes {Ka}. So, we can write the perimeter of the hexagon, before and after the scaling as -
P{i} = P{before scaling} = 6 x side = 6a
P{i} = 6a ... Eq { 1 }
P{f} = P{after scaling} = 6 x 6a = 36a
P{f} = 36a ... Eq { 2 }
The total of the internal angles of the hexagon will remain 720° only.
Therefore, the effect of scaling on a hexagon by the scale factor of 6 is discussed above.
