Answer:
Are you asking for a fraction?
Step-by-step explanation:
Answer:
x=2/5 y= -2/3
Step-by-step explanation:
Replace x with 0 to find Y and solve, so it'd be 5(0)-3y=2, which would be -3y=2. Divide each side by -3, and you'll get y= - 2/3. Then repeat the same but replace the y with 0 and solve it out. :)
The advance purchase price is $90.
Step-by-step explanation:
Ticket price after deadline = $99
Let,
x represents the advance-purchase price.
Suppose that the advance purchase price is 100%.
As 10% increases, the amount becomes;
(100+10)% = 110%
The amount after deadline is 110% of advance purchase price.
110% of x = 99
Dividing both sides by 1.1
The advance purchase price is $90.

Answer:
z-score=0.385
(See attached picture)
Step-by-step explanation:
The procedure to find the z-score will depend on the resources we have available. I have a table with the area between the mean and the value we wish to normalize, so the very first thing we need to do is precisely find this area we need to analyze.
Everything to the left of thte mean will represent 50% of the data, so we start by subtracting:
50%-35%=15%
so we need to look in the table for the value 0.15.
In my table I can see that for an area of 0.15, the z-score will be between 0.38 (z-score of 0.1480) and 0.39 (z-score of 0.1517).
By doing some interpolation, you can determine a more accurate value of the z-score to be 0.385.
Look at sample problem 23.2. How many unpaired electrons are in (enter a number such as 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) 1. Ag

- Ag+ = No unpaired electron
- Mn3+ = 4 unpaired electron
- Cr3+ = 3 unpaired electron

What are unpaired electrons?</h3>
- An unpaired electron is an electron that occupies an atom's orbital single rather than as part of an electron pair.
- Each atomic orbital of an atom can hold two electrons with opposing spins.
- Because the formation of electron pairs is generally energetically advantageous, whether as a chemical bond or as a lone pair, unpaired electrons are extremely uncommon in chemistry because an entity carrying an unpaired electron is usually quite reactive.
To find the unpaired electrons:
- Ag+ represents the d10 system. Because there are no unpaired electrons, the system is diamagnetic.
- Mn3+ has the electronic structure [Ar]3d44s0. In 3d, there are four unpaired electrons.
- Because of the loss of three electrons, the chromium ion Cr3+ has 24e3e=21e.
Therefore, unpaired electrons are:
- Ag+ = No unpaired electron
- Mn3+ = 4 unpaired electron
- Cr3+ = 3 unpaired electron
