What is the easiest way to divide whole numbers to fractions?
Just follow these two easy steps:
1. Multiply the whole number to the denominator of the fraction. In other words, the bottom number of the fraction will be multiplied to the whole number, like this:
12 ÷ 6/7 = n
<u> 6 </u>
7 x 12
You will have 6/ 84.
2. Simplify.
6 = 1, 2, 3, 6
84= 1, 2, 3, 4, 6, 7, 12, 14, 21, 42, 84
the GCF is 6. divide both numbers by 6, so the answer will be 1/14.
You can also get the reciprocal and proceed to multiplication , like this: (12/1 is the fractional form or the whole number 12.)
1/12 x 6/7=n
that makes 6/84 or 1/14.
Answer:
Range = $115
Variance = $1915.2857
Standard deviation = $43.764
Step-by-step explanation:
Given the data:
234 160 119 131 218 207 146 141
Arranging in ascending order :
119, 131, 141, 146, 160, 207, 218, 234
The range = maximum - minimum
The range = 234 - 119 = 115
The variance :
Σ(x - mean)²/n-1
The mean = Σx / n
The mean = 1356 / 8 = 169.5
Variance :
Σ(x - mean)² = (119-169.5)² + (131-169.5)² + (141-169.5)² + (146-169.5)² + (160-169.5)² + (207-169.5)² + (218-169.5)² + (234-169.5)² = 13407
n - 1 = 8 - 1 = 7
Variance = 13407 / 7 = 1915.2857
Standard deviation = √variance
Standard deviation = √1915.2857
Standard deviation = $43.764
Answer:
B. Negative
Step-by-step explanation:
So first, we want to locate the variable.
y (x/y) = (y/1) (x/y)
= (xy/y)
= x
The y/y cancels out and now we know we need to find the sign of x. Because x is to the left of 0, it's negative. Anything to the left decreases and anything to the left of 0 is (-).
Answer:
the degree of the polynomial is 5
None of these answers match up to the equation. The answer is 2. 2^2, 2x2=4
4+4=8
8=2^2+4
