Answer:
Step-by-step explanation:
breadth = x
length = 2x
Perimeter = 540m
2*( length + breadth ) = 540
2 *(2x + x) = 540
3x = 540/2
3x = 270
x = 270/3
x = 90 m
Breadth = 90m = 90 *100 = 9000 cm
Length = 2*90 = 180 m = 180 * 100 = 18000 cm
No.of bricks = Area of room/ area of one brick
= 9000 * 18000 / 20 * 12
= 675000 bricks

a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is
D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=
E)
F)
p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7

Answer:
95:95:19
Step-by-step explanation:
1.Divide 209 by 11.(209÷19)
2.Multiply 19×5 since 5/11 of the coins are nickels.(19×5=95)
3.Multiply 19×5 again since 5/11 of the coins are dimes.(19×5=95)
4.Multiply 19×1 since there would be 1/11 left of the coins which are quarters. (19×1=19)
5.Check your awnser by adding 95+95+19.(95+95+19=209)
