Answer:

x=70

Step-by-step explanation:

To solve this problem, you set up the equation 45+(2x-5)=180

Next, subtract 45 from 180 to get the equation 2x-5=135

After that, add 5 to 135 to get 2x=140

Divide 140 by 2 to get X=70

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>

  • 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>
