Question

answer to be the brainliest

Answer 1

According to me,

X 1 2. 3. 4. 5

Y. 3. 5. 9. 15. 2

This is a logical questions.

After 15, 2 comes as in the above it states that X=2,Y=5.So according to this logic if X=5,Y=2.

If you like please mark this as brainliest.

Answer 2

Given:

x             f         xf

1             3         3

2            5         10

3            9         27

4            x        4x

5            2         10.

           ----         -----

         19 + x      50 + 4x.

It is given that Arithmetic mean is 2.96.

⇒ 2.96 = (50 + 4x)/(19 + x)

⇒ 2.96(19 + x) = 50 + 4x

⇒ 56.24 + 2.96x = 50 + 4x

⇒ 6.24 = 1.04x

⇒ x = 6.

Therefore, the missing frequency is 6.

Hope it helps!
