Hi there

To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question

While the amount invested at 5% is
6000-4000=2000

Good luck!

Classify each substance as either a conductor or insulator.
IceJOKER [234]

A sample of mercury-conductor

A piece of glass-insulator

A rubber hose-insulator

A negatively ionized lithium paste-conductor

<u>Step-by-step explanation:</u>

Conductors are substances that allow the flow electricity through them whereas insulators do not permit the flow of electricity through them.

Mercury is  a liquid metal and due to its metallic nature, it is a fair conductor of electricity because metals have free electrons that carry the electric charge through the material.

Rubber and glass are insulators whereas a negatively charged lithium paste is a conductor.

The number of years of education of self-employed individuals in the united states has a population mean of 13.6 years and a pop
muminat

Answer:

0.3 years

Step-by-step explanation:

With problems like these, I always like to start by breaking down the information into smaller pieces.

μ = 13.6

σ = 3.0

Survey of 100 self-employed people

(random variable) X = # of years of education

So now we have some notation, where μ represents population mean and σ represents population standard deviation. Hopefully, you already know that the sample mean of x-bar is the same as the population mean, so x-bar = 13.6. Now, the question asks us what the standard deviation is. Since the sample here is random, we can use the Central Limit Theorem, which allows us to guess that a distribution will be approximately normal for large sample sizes (that is, n ≥ 30). In this case, our sample size is 100, so that is satisfied. We're also told our sample is random, so we're good there, too. Now all we have to do is plug some stuff in.

The Central Limit Theorem says that for large values of n, x-bar follows an approximately normal distribution with sample mean = μ and sample standard deviation = σ/√n. So, with that info, all we need to do to find the standard deviation of x-bar is to plug our σ and n into the above formula.

σ(x-bar) = σ/√n

σ(x-bar) = 3.0/√100

σ(x-bar) = 0.3

So your answer here is .3 years.

Solve x − 2y = 3 for x.
wolverine [178]

Answer:

x=2y+3

Step-by-step explanation:

So we have the equation:

x-2y=3

And we want to solve for x. In other words, we want to isolate the x-variable.

So, add 2y to both sides of the equation.

(x-2y)+2y=(3)+2y

On the left, the 2y cancel. Simplify the right:

x=2y+3

And we're done!
