If the mean of a symmetrical distribution is 170, which of these values could be the median of the distribution?

B. 170

Step-by-step explanation:

We have been given that the mean of a symmetrical distribution is 170. We are asked to choose the value for the median of the distribution from our given choices.

Since we know that the median of a symmetrical distribution is equal to mean of the distribution, therefore, the median of our given distribution will be also 170 and option B is the correct choice.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
