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.
Answer:
Volume of the prism = 140 cubic inches.
Step-by-step explanation:
The edge length of the cube is 1/2 inches.
The volume of the cube is given by

Now, it has been given that there are 1120 cube is completely filled in the prism. Hence, we have to the multiply the volume by 1120.
Volume of the prism = 1120 × 0.125
Volume of the prism = 140 cubic inches.
