Answer:
10 x 10 x 10 x 10 x 10
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that X and Y are independent random variables with the following distributions:
x -1 10 1 2 Total
p 0.3 0.1 0.5 0.1 1
xp -0.3 1 0.5 0.2 1.4
x^2p 0.3 10 0.5 0.4 11.2
Mean of X = 1.4
Var(x) = 11.2-1.4^2 = 9.24
y 2 3 5
p 0.6 0.3 0.1 1
yp 1.2 0.9 0.5 0 2.6
y^2p 2.4 2.7 2.5 0 7.6
Mean of Y = 2.6
Var(Y) = 11.2-1.4^2 = 0.84
3) W=3+2x
Mean of w =3+2*Mean of x = 7.2
Var (w) = 0+2^2 Var(x)= 36.96
Answer:
288 units^3
Step-by-step explanation:
To find the volume of this prism, first find the area of the triangular end.
A = (1/2)(base)(height) comes out to A = (1/2)(6)(8), or A = 24 square units.
Next, multiply this area by the length of the prism: V = (24 units^2)(12 units) = 288 units^3
The volume is 288 units^3
Answer:
13/6 is the missing fraction
Step-by-step explanation:
well consider the missing integer as x
then 5/2 -x=1/3
so, -x=1/3 -5/2
-x = -13/6
x= 13/6
The events are independant (i.e. what she rolls on the cube has no impact on how the spinner works). The probability of two independant events is given by:
For the cube, 1/2 the numbers meet our requitment of being even, so:
For the spinner, there are 3 odds out of 5 (1, 3 & 5) so:
and then:
