Find the values of the mode when median is given to be 5 and mean is 7.
Reil [10]

Answer:

<u>Mode = 1</u>

Step-by-step explanation:

<u>Relation between the Central Measures of Tendency</u>

  • Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
  • The formula between the three is given by :
  • ⇒ <u>Mode = 3Median - 2Mean</u> or <u>Mode + 2Mean = 3Median</u>

<u></u>

<u>Solving</u>

  • We know that :
  1. Median = 5
  2. Mean = 7

Therefore,

  • Mode = 3(5) - 2(7)
  • Mode = 15 - 14
  • <u>Mode = 1</u>

Answer:

the slope is POSITIVE (answer A)

Step-by-step explanation:

The line goes through: (-1, -2)  and ( 2, 1)

Then the slope can be calculated as:

slope = (y2 - y1) / (x2 - x1)

in our case:

slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1

Therefore, the slope is POSITIVE (answer A)
