Answer:
standard deviation is 2.886 [expected points]
Step-by-step explanation:
Let x is number of points scored so that given target uniformly dstributed between 0 and 10
clearly X uniform(0,10)
mean is defined as 
we know that variance is given as 
= 8.333
therefore standard deviation is 
standard deviation is 2.886 [expected points]
In the number 880, the first eight is ten times that of the
second eight. This is the first way in which the 8’s are related to one
another. The second way that the two 8’s are related is that is that if the
both 8’s change their respective places, then also the number will remain the
same. Since in this case the number in the tens place and the hundreds place
are same, so interchanging them will not have any effect on the overall number.
Answer:
x = -3
Step-by-step explanation:
10(x-5) = -80
10x - 50 = -80
10x -50 + 50 = -80 + 50
10x = -30
10x ÷ 10 = -30 ÷ 10
x = -3
Answer:
I think the F could mean force like F = ma (mass acceleration)
Step-by-step explanation:
Labor costs of the workers at $8 per hour working 40 hours each=$640
Revenue for the week=$2000
therefore labor cost as a percentage of revenue would be=32%
