To evaluate the <span>probability that in a randomly selected hour the number of watches produced is greater than 500 we proceed as follows:
z=(x-</span>μ<span>)/</span>σ
where:
x=500
μ=500
σ=100
thus
z=(500-500)/200=0
Thus:
P(x>500)=1-P(x<500)=1-P(z<0)=1-0.5=0.5
Answer: 0.5~50%
The answer is C because it equals 9
Answer:
0.3
Step-by-step explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
<h3>---------------------------</h3>
All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is <u>0.3</u>
