4 Packs of water and 7 Packs of candy bars.
So, we wanna know the smallest number that both 35 and 20 will go into.
Find the Least Common Multiple (LCM), but to find the LCM we need to find the prime factorization of each of the following number :-
~Now multiply all the numbers by 5 :-
This means she needs 140 bottles of water and 140 candybars.
Water is sold in packs of 35, this means that she needs :
Candy bars are sold in packs of 20, this means she needs :

Answer: The mean and standard deviation are 567.2 and 89.88 resp.
Step-by-step explanation:
Since we have given that
For 370 parts per million = 7% = 0.07
For 440 parts per million = 10% = 0.10
For 550 parts per million = 49% = 0.49
For 670 parts per million = 34% = 0.34
So, Mean of the carbon dioxide atmosphere for these trees would be
And
So, Variance would be
So, the standard deviation would be
Hence, the mean and standard deviation are 567.2 and 89.88 resp.
