Answer:
Step-by-step explanation:
An Improper Fraction has a top number larger than (or equal to) the bottom number.
To convert a whole number -12 into an improper fraction we can divide the whole number by one to turn it into a temporary fraction.
Also we could multiply and divide -12 by another number greater than one, for example:
There are several ways we can write -12 in the improper fraction form.
Answer:
Mean = 3.4
Variance = 1.088
Standard deviation = 1.0431
Step-by-step explanation:
The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is 
Thus,
The variance of the binomial distribution is 
, where 
is the variance of the binomial distribution, so
The standard deviation 
is the square root of the variance 
so
Answer:
$260
Step-by-step explanation:
Actual price + 8% of actual price=$280.80
Let x= actual price
8% of actual price=8/100 of x
=0.08x
x + 0.08x=$280.80
1.08x=$280.80
x=$280.80/1.08
x=$260
Price of the jacket before sales tax=$260
Check:
8% sales tax of $260
=8% of $260
=8/100×$260
=0.08×$260
=$20.8
Purchasing price= actual price+ sales tax
=$260+$20.8
=$280.80
Substitution
Step 1: Solve for x or y in either of the two equations. In the equations that you are given, y is already solved for you.
Step 2: Plug in 2x + 6 into the opposite equation.
2x + 6 = -3x + 16
- 6 - 6
------------------------------
2x = -3x + 10
+ 3x + 3x
------------------------------
5x = 10
------ ------
5 5
x = 2
Step 3: Plug in the x value into either equation.
y = 2(2) + 6
y = 4 + 6
y = 10
The final answer gets expressed as a coordinate pair: (x,y) (2,10)
I hope this helps you :)
