Answer:2 pizzas
Step-by-step explanation:
2 2/3 and 2 5/6 can both be rounded to 3. Double that and you get 6. Since there were 8 pizzas originally,subtract 6 from 8 to get 2 remaining pizzas.
Answer:
17x6=102/2=51 rounded is 50-x=30
Step-by-step explanation:
LOL this is funny u expect people to help u yet when u answer them apparently its spamming so u can gain points is that right?
perhaps i should spam u i would if i were as immature as u so ill give u an answer.. like u should've done rather than spam me OH AND FYI I REPORTED YOU THIS SITE IS MADE FOR HELPING OTHERS OR BEING HELPED NOT GAINING POINTS LIKE A VIDEO GAME.
https://www.thecanadianencyclopedia.ca/en/article/social-and-welfare-services hope that helps and sorry i couldn't give u a straight answer because i couldn't find anything that talked about a list of social benefits/governments but this might work.
The second one, and you as well ☺️
Answer:
Mean=685
Variance=36.7
Step-by-step explanation:
The mean of uniform discrete distribution can be expressed as the average of the boundaries
mean=( b+a)/2
The variance of uniform discrete distribution can be expressed as the difference of the boundaries decreased by 1 and squared, decreased by 1 and divided by 12.
σ²=[(b-a+1)^2 - 1]/12
We were given the wavelength from from 675 to 695 nm which means
a= 675, b= 695
We can now calculate the mean by using the expresion below
mean=( b+a)/2
Mean=( 675 + 695)/2
=685
The variance can be calculated by using the expression below
σ²=[(b-a+1)^2 - 1]/12
σ²=[(695-675+1)^2 -1]/12
σ²=440/12
σ²=36.7
Therefore, the the mean and variance, of the wavelength distribution for this radiation are 685 and 36.7 respectively
