There are 46 more skiers than snowboarder
Step-by-step explanation:
Given
Ratio of Snowboarders to Skiers
On Friday:
On Saturday:
Population = 168
Required
Determine the difference in the number of skiers and snowboarders on Saturday
On Saturday, we have
Calculate Total
Calculate the number of skiers
(Approximated)
Calculate the number of snowboarders
(Approximated)
Calculate the difference
<em>Hence, there are 46 more skiers than snowboarder</em>
Step-by-step explanation:
yes it is . becoz if you kbow the 5 is to 8 means it is an irrational number

Answer:
0.98732
Step-by-step explanation:
Given that :
Mean = 10 minutes
Variance = 2 minutes
For less than equal 40 jobs
Mean (m) = 40 * 10 = 400 minutes
Variance = 2 * 40 = 80 minutes
Standard deviation (s) = √variance = √80
Converting hours to minutes
X = 60 * 7 = 420 minutes
P(X≤ 420) :
Z = (x - m) / s
P(X≤ 420) :
Z = (420 - 400) / √80
Z = 20 / √80 = 20 / 8.9442 = 2.236
P(Z ≤ 2.236) = 0.98732
