Answer:
2/7
Step-by-step explanation:
I am assuming that you mean 285714 repeating.
You just have to memorize or learn to recognize the order of decimal digits for fractions over 7, unless you want to do it algebraically.
1/7=0.142857 repeated
2/7=0.285714 repeated and so on
Answer:
32
Step-by-step explanation:
angle a is the outside angle. It creates a circle that will always equal 360 degrees. Since the outside angle is 302, the inside angle must be 58 degrees (360-302). The top square angle will be 90 degrees (a square angle is always 90 degrees). Since the angles in a triangle always add up to 180 degrees, we need to add 58 and 90, and then subtract it from 180, which equals 32. So, angle x equals 32.
Its a quadratic. Since x cant be a negative number i used the x=4 answer to plug into the length and width

Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The number of student is 
The highest amount is
$200
The lowest amount is
$75
The sample mean is
&140
The Standard deviation of this set is mathematically evaluated as

Substituting values


The margin of error (ME) is mathematically evaluated as

Where
is the critical value for
i.e the significance level
From the critical value table this is
So
