Answer:

Formula for mean in grouped data

= Zfx/ Zf

f = sum of the number of mice

= 35

Frequency = 39 + x

Mean = 7

Fx = 20 + 78 + 112 + 8x + 54

= 264 + 8x

7 = 264 + 8x/ 39 + x

7(39+x) = 264 + 8x

After solving you will get

x = 9

Hope this helps.

Find the equation of quadratic function determined from the graph below?
Aleksandr [31]

Step-by-step explanation:

The x-intercepts are x = -1 and x = 5, so:

y = k (x + 1) (x − 5)

The vertex is (2, -3), so:

-3 = k (2 + 1) (2 − 5)

-3 = -9k

k = 1/3

y = 1/3 (x + 1) (x − 5)

Simplifying:

y = 1/3 (x² − 4x − 5)

y = 1/3 x² − 4/3 x − 5/3
