Answer:

The value of the provide equation is L=\frac{K}{2M+2N}.

Step-by-step explanation:

Consider the provided equation.

K=2LM + 2LN

We need to solve the equation for L.

Take L common from right side.

K=L(2M + 2N)

Divide both the sides by 2M+2N.

\frac{K}{2M+2N}=\frac{L(2M + 2N)}{2M + 2N}

L=\frac{K}{2M+2N}

Hence, the value of the provide equation is L=\frac{K}{2M+2N}.

Find the inverse of g(x)=1/3x - 7 and then find its domain and range if you can show steps that would be gladly appreciated than
Schach [20]

Answer:

g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

Step-by-step explanation:

Let y = 1/3 x - 7

1/3 x = y + 7

Multiply both sides by 3:

x = 3(y + 7)

So the inverse of g(x) = g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

A random sample has been taken from a normal distribution and the following confidence intervals constructed using the same data
LuckyWell [14K]

Answer:

(25.53, 37.87): 95% CI

(23.59, 39.81): 99% CI

Step-by-step explanation:

The margin of error of a confidence interval is given by:

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

z is related to the confidence level. The higher the confidence level, the higher the values of z, and thus, we wider the confidence interval is.

In this question:

The narrower C.I. is the 95%, and the wider is the 99%. So

(25.53, 37.87): 95% CI

(23.59, 39.81): 99% CI

A customer deposits $500 in an account that pays 4% annual interest. What is the balance after 3 years if the interest is compou
SIZIF [17.4K]

Answer:

Option D

Step-by-step explanation:

The compounded interes formula states that:

V(t) = P (1 + r/n)^ (nt)

t = years since initial deposit  = 3

n = number of times compounded per year  1

r = annual interest rate (as a decimal)  = 4% / 100 = 0.04

P = initial (principal) investment = $500

Then V(t) = $500 ( 1 + 0.04/1)^3 = 562,43

So the correct answer is option D.

This would just look like a bar graph.

On the horizontal axis, put your 4 different categories of 2, 3, 4, or 5.

On the vertical axis, label it by the percents: 0.10, 0.20, 0.30, 0.40

Then, make a bar at the correct height for each category.
