Question

During an experiment, the temperature of a liquid was measured several times. The temperatures, in degree Celsius, listed in increasing order, are 21, 25, x, 40, and 50. If the arithmetic mean of these temperatures is equal to the median, what is the value of x?A. 34.B. 35.C. 36.D. 37.E. 38.

Answer 1

k

Step-by-step explanation:

Answer 2

option A

Step-by-step explanation:

given,

increasing order

21, 25, x, 40, 50

median of the given number = x

Mean of the temperature = mean

mean =
`(21+25+x+40+50)/(5)`

x =
`(21+25+x+40+50)/(5)`

5 x = 136 + x

4 x = 136

`x = (136)/(4)`

x = 34

correct answer is option A
