Answer:

20.5 cm

Step-by-step explanation:

I just used Pythagorean theorem in which c^2=a^2+b^2

so this is c^2= 225 + 196 and then you get c^2= 421 and finally you get the square root of 421 so this way you finally get 20.5 cm

The list of integers 15, 20, 26, x, y, 32 has a mode of 26 and an arithmetic mean of 27. What is the median of the list of numbe

OleMash [197]

Answer:

The median of the list is 26.

Step-by-step explanation:

Since the <u>mode of the list is 26</u>, and so far we only have one occurrence of 26 in the list, we know that one of our unknowns must equal 26.

If we set x = 26, we can then s<u>olve for y using the arithmetic mean formula. </u>We are left with: $\frac{15+20+26+26+y+32}{6} = 27$ .

Solving for y leaves us with y=43.

Finally, we can put the list in order and find the middle values. Since the two middle values are 26, the median of the list is 26.
