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]

A rectangle has a width of 4 centimeters and a perimeter of 26 centimeters. Find the length.

Jobisdone [24]

Answer:

length = 9 cm

Step-by-step explanation:

perimeter = p =26 cm

width = w= 4 cm

perimeter of a rectangle= 2*w+2*L

L= length

so we have:

26 = 2*(4) +2*L

26= 8 +2L

26-8 = 2L

18 = 2L

L= 18/2

L =9 cm = length
