Mean = all numbers added up ÷ amount of numbers So 22 + 24 + 26 + 20 + 29 + 28 + 26 = 175 175 ÷ 7 = 25 for mean Median = middle number when arranged in order 20, 22, 24, 26, 26, 28, 29. Middle number is 26. Mode = most frequent number Also 26 because it appears twice whereas all the other numbers only appear once. Range = highest number - lowest number 29 - 20 = 9.

When she checked the answer by estimating, it did not make sense. What error did Janice make?
Leokris [45]
<h2>Answer</h2>

Janice convert a mixed number to the wrong improper fraction

<h2>Explanation</h2>

To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the result to the numerator of the fraction; while keeping the denominator of the fraction as the denominator of the improper fraction.

Let's convert our mixed numbers to improper fractions:

To convert 10\frac{5}{6} we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:

10\frac{5}{6} =\frac{(10*6)+5}{6} =\frac{60+5}{6} =\frac{65}{6}

Now let's convert 1\frac{2}{3}:

1\frac{2}{3}=\frac{(1*3)+2}{3} =\frac{3+2}{3} =\frac{5}{3}

Notice that Janice converted 1\frac{2}{3} as \frac{5}{2}, which is incorrect.

Since 1\frac{2}{3} =\frac{5}{3}, we can conclude that Janice convert a mixed number to the wrong improper fraction.

What is the answer for number 8?
vfiekz [6]
<h2>527.52</h2>

Step-by-step explanation:

radius (r) = 6

height (h) = 8

total surface area = 2π×r×h + 2πr²

= (2×3.14×6×8) + (2×3.14×6×6)

= (301 44) + (226.08)

= 527.52
