what is the √-1 please under complex numbers
Imaginary number (i'm serious, that's what it's called i'm not trying to be funny)
Answer:
i is the answer
Step-by-step explanation:
When using complex numbers you take the square root of negative one as i
for example: If I have √-16 I need to take √-1 out first and then put i in for √-1. Therefore my answer would be i√16
i = imagiary number aka √-1
In your case the answer is i

1, 3/2 , 9/4 ... Find the 9th term
Answer:
6561/256
Step-by-step explanation:
You can notice that each term is equal to the previous term multiplied by 3/2. This means that it is a geometric series. The formula to find the nth term is as follows:
[tex]a_{n}= a_{1} *(r)^{n-1}[/tex]
The first term, a1, is 1 and r, the common ratio is 3/2 because that is what you are multiplying by. We can also substitute in n as 9 because we are looking for the ninth term:
[tex]a_{9} = 1 *(\frac{3}{2} )^{9-1}\\\\a_{9} = (\frac{3}{2})^{8}\\\\a_{9} =\frac{3^8}{2^8} \\\\a_{9} =\frac{6561}{256}[/tex]

Each of ten tickets is marked with a different number from 1 to 10 and put in
a box. If you draw a ticket from the box, what is the probability that you will
draw 5, 6, or 4?
Answer:
10 Percent
Step-by-step explanation:
Common sense 10 tickets, 1,2 ,3.. to 10 will all be 10 percent but if you want 5 6 and 4 then that will be 10% times 3 which is 30% chance of 5 6 or 4.
Answer:
3/10
Step-by-step explanation:
The probability of drawing a card out of the box is 1/10. So the probability of drawing 3 tickets out of the box is
[tex] \frac{1}{10} + \frac{1}{10} + \frac{1}{10} = \frac{3}{10} [/tex]

CH4+2O2->CO2+2H2O If you change the 2 in front of 2O2 to a 3 what will be the change in the results on the right side of the equation
Answer: There is an extra O2 molecule left over.
Step-by-step explanation: A reaction between four oxygen molecules and two methane molecules will not have any leftovers.
There is an extra O2 molecule left over.
What is reaction?In a chemical reaction, one or more substances—also known as reactants—are changed into one or more additional substances—also known as products. Chemical elements or chemical compounds make up substances.
Reactants are the chemicals that take part in a chemical reaction. The resulting materials are referred to as products. The reactants' characteristics are different from those of the products. Additional Names: chemical change, reaction
Given:
C[tex]H_4[/tex]+2[tex]O_2[/tex] -> C [tex]O_2[/tex] + 2[tex]H_2[/tex]O
So, if we change the 2 in front of 2O2 to a 3 then we have 4 oxygens to react.
Then, There won't be any byproducts of a reaction between two methane molecules and four oxygen molecules.

No, they are not equivalent ratios.
4) Cost of six pack of drinks = $ 2.99
Unit rate = 2.99 ÷ 6
= $ 0.50
No, her sister was wrong and the unit rate is $ 0.50
5) Cost of 3 lb = $ 1.89
Unit rate = 1.89 ÷ 3 = $ 0.63
Cost of 5 lb = $ 2.49
Cost of 1 lb = 2.49 ÷ 5 = $0.50
0.63 > 0.50
Best buy : 5 lb apples for $2.49
6) 6 bagels for $ 4.20
Unit rate = 4.20 ÷ 6 =$ 0.70
12 bagels = $ 7.80
Unit rate = 7.80 ÷ 12 = $0.65
0.70 > 0.65
Best buy: 12 bagels for $ 7.80

The XYZ Company is planning to introduce a new product line and will build a new factory to produce the parts and assembly the final products for the product line. The new product line will include 110 different models. Annual production of each model is expected to be 1100 units. Each product will be assembled of 700 components. All processing of parts and assembly of products will be accomplished in one factory. There are an average of 12 processing steps required to produce each component, and each processing step takes 90 sec. (includes an allowance for setup time and part handling). Each final unit of product takes 2.0 hours to assemble. All processing operations are performed at work cells that each includes a production machine and a human worker. Products are assembled on single workstations consisting of two workers each. If each work cell and each workstation require 200 ft2, and the factory operates one shift (2000 hr/yr), determine: (a) how many production operations, (b) how much floorspace, and (c) how many workers will be required in the plant. If the company were to operate three shifts (6000 hr/yr) instead of one shift, determine the answers to (a), (b), and (c).
