How do you know if a fraction is equal to one?

2 answers:

8 0

2/2 = 1 and (1/3)^0 = 1 so x/x = 1 because there is same number and (x/y)^0= 1 because its 0 and 1/1 is always 1 these are the fractions that are always 1 :))
i hope this be helpful
have a nice day

You would know because for example, if it's out of 4 and the fraction said 4/4, that would mean one. 3/3 would mean one. 2/2 and so on

use elimination to solve. For a production of sweeney Todd in Las Vegas, orchestra seats cost $42 and mezzanine seats cost $25.

lidiya [134]

They bought 8 orchestra seats and 6 mezzanine seats.

Step-by-step explanation:

Cost of one orchestra seat = $42

Cost of one mezzanine seat = $25

No. of people = 14

Amount spent = $486

Let,

x be the number of orchestra seats

y be the number of mezzanine seats

According to given statement;

x+y=14 Eqn 1

42x+25y=486 Eqn 2

Multiplying Eqn 1 by 25;

$25(x+y=14)\\25x+25y=350\ \ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2 to eliminate y;

$(42x+25y)-(25x+25y)=486-350\\42x+25y-25x-25y=136\\17x=136$

Dividing both sides by 17

$\frac{17x}{17}=\frac{136}{17}\\x=8$

Putting x=8 in Eqn 1

$8+y=14\\y=14-8\\y=6$

They bought 8 orchestra seats and 6 mezzanine seats.

Alecsey [184]

Answer:

below

Step-by-step explanation:

for f(x) insert the x into the equation.

example:

f(-6) → -(-6+2)^2

follow pemdas

p: -(-4)^2

e: -(16) because -4 times -4 is 16.

m: -(16) → -16

Do that for the rest of the first table. As for the inverse table, f(x) and x will just switch spots. so (-6,-16) will become (-16,-6)

Answer:

σX = 3161

Step-by-step explanation:

The standard deviation is the square root of the multiplication of each probability multiplied by the squared difference between the values and the mean.

In this question:

$\sigma X = \sqrt{0.999*(200-100)^2 + 0.001*(-99800-100)^2} = 3160.7$

Rounding to the nearest dollar, σX = 3161
