Convert 48°36'12" to the nearest thousandth of a degree

uranmaximum [27]

48 degrees remains

divide minutes by 60

36/60 = 0.6

then divide seconds by 3600

12/3600=0.003 ( to nearest thousandth)

now add them all up

48 +0.6 + 0.003 = 48.603 degrees

A person aiming at a target receives 10 points if their shot is within 1 inch of the target, 5 points if it is between 1 and 3 i

Gelneren [198K]

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 $E(x) = \frac{a+b}{2}$

$\frac{0+10}{2} = 5$

we know that variance is given as $\frac{(b-a)^2}{12}$

$V(x) = \frac{(b-a)^2}{12}$

$\frac{(10-0)^2}{12}$

= 8.333

therefore standard deviation is $\sqrt{V(x)} = \sqrt{8.333}$

standard deviation is 2.886 [expected points]
