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.
B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
Answer:
The number is 79
Step-by-step explanation:
Let the number be 'x'
x + 17 = 96
Subtract 17 from both sides,
x + 17 -17 = 96 - 17
<h3> x = 79</h3>
<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 
we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:
Now let's convert 
:
Notice that Janice converted as 
, which is incorrect.
Since 
, we can conclude that Janice convert a mixed number to the wrong improper fraction.
<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
