<span>What is the answer to this 6.7w- (-3)w = -5?

</span>Simplify brackets
<span>6.7w+3w=-5

</span>Simplify 6.7w+3w to 9.7
<span>9.7w=-5<span>9

</span></span>Divide both sides by <span>9.7
</span>
w= - 5/9.7

And IDK if you need to simplify it or not but if you do it would be,

<span><span>w=−0.515464</span><span>
</span></span><span>

6.7w - (-3)w = -5

42w + 3w = -5

45w = -5

w = -5/45

w = -1/9

Hope this helps!

Hello can someone explain to me how to do this?
wel
A)
you square both sides
by squaring the left side, you get rid of the square root leaving only x one that side. But you also need to square the other side because whatever you do to one side you have to do to the other.

Answer: x=o/a^2

b)
To get o on its own on one side you multiply a. You basically do the opposite of what a originally does to cancel it out. So originally, a is dividing o so if you do the opposite, a will multiply on both sides.

a X o cancels out the a, leaving only o.
But whatever you do to one side, you have to do to the other. so Vx (square root of x) has to also be multiplied by a.

Answer: Vx X a=o

c) this is basically the same as b).

apply what i said in b) to this and you will get your answer

to cancel out o, you multiply both sides by o.
because o is getting divided, you will have to do the opposite which is multiply o.

Answer: Vx X o=a

Please give me the answer to number 2 you don’t need to explain it just give me the answer

Hello from MrBillDoesMath!

Answer:   Perimeter = 17x + 4

Discussion:

(So you are trying to sneak #2 out of me too..... );

Perimeter = sum of lengths of sides. Starting at the bottom of the figure and proceeding counterclockwise.

Perimeter =  (3x +2) + (3x+2) + (4x-1) + (4x-1) + (3x + 2) .

Separate and combine x's and constants:

Perimeter = (3x + 3x+4x+4x+3x) + (2 + 2 -1 -1 + 2) =

                = 17x + 4

You answer has the wrong constant value ( you wrote 17x + 1. The constant should be 4)


Thank you,

MrB

What is the difference between a parameter and a statistic? A parameter is an aspect of an individual subject or object being me
Aliun [14]

Answer:

A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample

Step-by-step explanation:

In statistics we have to deal with populations and samples to carry out our studies. A population is a large group under consideration and the elements or members of the population have some common features or attributes. For example, all the school going kids in a certain town will be considered a population. Sample on the other hand is a subset(a part) of the population. For example, all school going kids in the town aged 5-6 years will be considered a sample.

The term Parameter and Statistic are very similar as they represent some numeric description. Parameter represents the data of the entire population, while statistic represents that data of a sample. An easy way to remember this is to match the initials i.e. Parameter for Population and Statistic for Sample.

Considering this, we can say the correct answer is:

A parameter is a numerical measurement describing data from a population. A statistic is a numerical measurement describing data from a sample
