Answer:
Al Capone, Fred "Killer" Burke, and Bugsy Moran.
Explanation:
Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.
When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran. But in 1933, to secure himself, he turned evidence against his friends and accomplices. But he was not to be safe for long, for he was gunned down by unknown assailants rumored to be ordered by Frank Nitti on October 9, 1933.
Answer:
C. 48
Explanation:
Simple thing to bear in mind; The number of neutrons is equal to the Atomic number - the Mass number. Because the Atomic number tells you the number of Protons, whilst the mass number tells you the number of both PROTONS and NEUTRONS. So 84 - 36 is 48. You have 48 neutrons

Although the data in the question is not clearly stated, the correct date is stated in the image attached to this answer and it is also stated below
What is the sample variance of the following data, which describe the height growth of 10 foxtail pine trees grown in a common garden ( give your answer to one decimal place)?
Tree Height(cm)
1 25.6987
2 19.6587
3 11.4780
4 9.11130
5 16.8747
6 14.7771
7 33.0001
8 24.0000
9 19.4441
10 14.1010
answer 51.9
Explanation:
what is a sample variance?
A sample variance (denoted as 
) is used to calculate how far a set of numbers are from the mean value of the set. Mathematically, it is defined as the average of the squared deviations from its mean value.
Let the individual value of the trees be represented as x₁ to x₁₀
Let the total number of Foxtail pine trees be N
To calculate the standard deviation, we will first calculate the mean or average of the height of the trees
1. Mean (μ) = 
= 
= 
2. we need to calculate the sum of the squares of the individual deviations.
∑[x-μ]²= 
3. Now the variance is ; (∑[x-μ]²) ÷ (N-1) and since N=10, then N-1 = 10-1 = 9
= 
we were asked the give our answer to one decimal place
∴ Variance()= 51.9
