Three times larger.

This is because you have to multiply 2m (the smaller prism) by three to get 6m (on the bigger prism), then you will find that if you multiply the rest of the numbers (on the smaller prism) by three you will get the exact numbers that are on the big prism. Hope this helps!

3 is wrong because is says surface area of the smaller and larger and the surface area of the small one is 10m^2 and the surface area of the larger one is 90m^2 so it would be 9 times larger.
Hope I helped!

a committee has eleven members. there are 3 members that currently serve as the boards chairman, ranking members, and treasurer.

Answer:

$\frac{1}{990}$

Step-by-step explanation:

The full question:

"A committee has eleven members. there are 3 members that currently serve as the boards chairman, ranking members, and treasurer. each member is equally likely to serve in any of the positions. Three members are randomly selected and assigned to be the new chairman, ranking member, and treasurer. What is the probability of randomly selecting the three members who currently hold the positions of chairman, ranking member, and treasurer and reassigning them to their current positions?"

The permutation of choosing 3 members from a group of 11 would be:

P(n,r) = $\frac{n!}{(n-r)!}$

Where n would be the total [in this case n is 11] & r would be 3

Which is:

P(11,3) = $\frac{11!}{(11-3)!}=\frac{11!}{8!}=11*10*9=990$

So there are total of 990 possible way and there is ONLY ONE WAY for them to be reassigned. Hence the probability would be:

1/990

Answer:

x = 1 and y = -2

Step-by-step explanation:

Given that,

2x-3y = 8 ..(1)

4x+3y = -2 ..(2)

Add equation (1) and (2),

2x-3y+4x+3y = 8+(-2)

6x = 6

x = 1

Put the value of x in equation (1).

2-3y = 8

2-8 = 3y

-6 = 3y

y = -2

Hence, the value of x is 1 and that of y is -2.

A weather forecaster predicts that there is a 45% probability of snow today. What is the probability that it will not snow?

Ilia_Sergeevich [38]

55% if the percent is out of 100%. in which most weather statisics are out of 100. in which you take 100-45= giving you 55%
