Answer:

Step-by-step explanation:

Mean would mean average, which in this case is $\frac{x+y}{2}$

so your equation would look like $\frac{69+x}{2}=41$

Next multiply both sides by to clear the fraction $2*(\frac{69+x}{2})$

to get $69+x=89$

Subtract 69 from both sides $69+x=82\\-69 -69$

you get $x = 13$

the variable Z is invery proportional to X. when X is 3, Z has the value 6. what is the value of Z when X = 12

MrMuchimi

"inversely proportional," please.

z = k/x

When x is 3, z = 6; find k: 6 = k/3, or k = 18.

Then z = 18/x. When x = 12, z = 18/12 = 2/3 (answer)

What is the center of the data?

satela [25.4K]

Answer:

$Median = 13$

Step-by-step explanation:

Given

See attachment for dot plot

Required

The center of data

This implies that, we calculate the median

From the attached plot,

$n = 13$ --- number of observation

So, the median is:

$Median = \frac{n + 1}{2}$

$Median = \frac{13 + 1}{2}$

$Median = \frac{14}{2}$

$Median = 7th$

The median is at the 7th position

At the 7th position, is 13

Hence:

$Median = 13$
