Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 24 + 0.44x = 19 - 24 + 1.69x
0.44x = -5 + 1.69x
0.44x - 1.69x = -5 + 1.69 - 1.69
-1.25 = -5
-1.25/-1.25 = -5/-1.25
x = 4

Answer:
4 is expected to be damaged out of the next 20
Step-by-step explanation:
From the observation made, we have that 4 of the toys were damaged and 16 were not damaged
Thus, the probability of having a damaged toy is 4/20 = 1/5
Now, for the next 20; we have 1/5 of them expected to be damaged
So, the expected damaged number out of the next 20 will be:
1/5 * 20 = 4
