<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
The amount of time spent reading email to the amount of time spent watching television is 1/12
Step-by-step explanation:
Given
Time to read email = 15 minutes
Time on television = 3 hours = 3*60 minutes = 180 minutes
Ration is the fraction between two things. In this case, the ration is from the amount of time spent reading email to the amount of time spent watching television
So,
Required ratio will be: 15/180
Simplifying => 1/12
So,
The amount of time spent reading email to the amount of time spent watching television is 1/12

Answer:
48 = divider 4 = divisor 54 = divider 6 = divisor
Step-by-step explanation:
Therefore, the answer to 48 divided by 4 calculated using long divison is 12 remanider 0 therefore, the answer to 54 divided by 6 calculated using long divison is 9 remanider is 0
The answer would be 66.30
