Mean Versus Median

Mathematics
1 answer:
Lina20 [59]3 years ago
4 0

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

$1.09 $1.29 $1.29 $1.35 $1.39 $1.49 $1.59 $1.79

Average value :

Sarah = $1.37

Andrew = $1.41

Obtaining the median:

(n + 1) / 2

n = number of observations = 8

(8 + 1) / 2 = 9 /2 = 4.5th observation

(4th +. 5th observations) / 2

(1.35 + 1.39) / 2 = $1.37

Finding the mean:

($1.09 + $1.29 + $1.29 + $1.35 + $1.39 + $1.49 + $1.59 + $1.79) /8

$11.28 / 8

= $1.41

Hence, the actual. Average value is the mean value of the data.

The median only gives the value at the middle of the distribution and not the average.

Without calculating, how do you know that the equation |4x-7|=-1 has no solution?
Helen [10]

Answer:

2. An absolute.value cannot be negative

Step-by-step explanation:

I.I'll explain it short why absolute.value cannot be negative

 Given |4x - 7| = -1

            4x  = -1 + 7

             4x = 6

               x = 3/2

II. Prove by x = 3/2

            |4(\frac{3}{2}) - 7| = -1

            |2(3) - 7| = -1

            |6 - 7| = -1

            | -1 | = -1

              1  = -1  false, not true

III. Absolute value is came from \sqrt{|x|}^{2}

As you knew square root value cannot be negative

So absolute.value cannot be negative.

Ask me for anything.
