1st order the data point from smaller to greater:
x = 25,31,46,52,55,67 (n=number of data points = 6)
2nd Add them up = 25+31+46+52+55+67 = 276
3rd : find the mean 276/5 = 46 = mean
4th make (x- mean)² for each x. EXAMPLE:
25-46 = -21 →→(-21)² = 441
31-46 = -15→→(-15)² = 225
AND SO ON AND SO FORTH. Then add all squared together you will get:
∑(x-mean)² = 1224
variance = ∑(x-mean)²/(n-1) = 1224-5 = 1219
Answer:
one-sixth
multiply the numerator (2) by the number of kids (3) because you are accounting for the fraction of the whole pizza. By doing this you should get 3/6. divide the denominator by the number of kids (3/3) getting you to a value of 1, and replace the denominator, making the amount of pizza one-sixth.
q<13
Step-by-step explanation:
2q is less than 26 so 1q has to be less than half of 26 or 13.

Answer:
1/2 x 1/2 = <u>1/4</u>
Step-by-step explanation:
<u>For example 1/2 is bigger than 1/3 which is also bigger than 1/4. It is bigger because if you divide 1 by 2, you get 0.5. Do in this case 1/2 is bigger than 1/4. </u>
