Answer:
$11535.60
Step-by-step explanation:
We have been given that Jackson deposited $5000 at 3.8% interest compound continuously when he was 18 years old.
To find the amount that Jackson will earn when he is 40 years old, we will use compound interest formula.
A= Amount after T years.
P= Principal amount.
e= Mathematical constant e.
r= Interest rate (in decimal form).
T= Time in years.
Let us convert our given interest rate into decimal form.
Upon substituting our given values in above formula we will get,
Therefore, Jackson will have $11535.60 in his account when he is 40 years old.
I suck at math but I got f(x)=(2x+3.5)^2-7.5
Answer and Step-by-step explanation:
Variance is the measurement of the spread bewteen the numbers of the data set and can be calculated by the formula:
σ² = ∑(x - ⁻x)² / n
1) With the data, find its mean (⁻x) by adding all the values and dividing the sum by total number of elements the data has;
2) Subtract each value of the data to the mean;
3) Square the result of the subtractions;
4) Add the squares;
5) Divide the sum by the total number of elements of the set;
6) The result is the Variance (σ²);
Standard Deviation is the measure of how far the values of the data set are from the mean and it is the square root of Variance:
σ = 
So, to calculate standard deviation, you just take the square root of the variance.
it is 18 your welcome have a good day
There's no pic or worksheet!!
