Answer:

Definition: Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.

Final Amount 10,400

soldi70 [24.7K]

Answer:

$9629.63

Step-by-step explanation:

I assume this is simple interest.

The formula for simple interest is

F = P(rt + 1)

where F = future value,

P = present value

r = annual interest rate

t = number of years

10,400 = P(0.02 × 4 + 1)

10,400 = 1.08P

10,400/1.08 = P

9,629.63 = P

Answer: $9629.63

What is the slope, y-intercept, and equation of a line given the points (-4, 0) and (1, 5)?

Alex Ar [27]

Answer:

$Slope: 1\\y-Intercept: 4\\Equation: y = x + 4$

Step-by-step explanation:

Given two points, we can find the equation of the line between them with the following:

$y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}$

First, we can calculate m, or slope

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)} = \frac{5}{5} = 1$

Next we can use the top equation and solve for b, the y-intercept

$y = mx + b\\y = x + b\\5 = (1) + b\\b = 4\\\\y = x + 4$

$Slope: 1\\y-Intercept: 4\\Equation: y = x + 4$
