Answer:
C) primary source document
Step-by-step explanation:
A canceled US Treasury check for the purchase of Alaska is an example of a C) primary source document.
A primary source document can be any document or artifact or recording that must have been created at the time under study.
Here, the canceled US Treasury check for the purchase of Alaska has a date stamp on it, that would be a primary source document for that time.

Answer:
(1/2,1) is on the graph of
B is correct.
Step-by-step explanation:
Given:
We are given a log function whose base 1/2.
Log property:
If base and mantissa is same then their value is 1
We need to choose correct point from the options.
Option 1: (1,1/2)
False
Option 2: (1/2,1)
True
Option 3:
Log is not defined for x=0.
Hence, (1/2,1) is on the graph of
(1/2,1) is the points is on the graph of y = log1/2x?
For (1, 1/2):
So, By Substituting x = 1 and y = 1/2 into the equation, we get:
1/2 = log₁/₂(1)
Since log of 1 to any base is always 0, the equation becomes:
1/2 is not equal to 1
In terms of Option 3: Log is not defined for x=0.
Therefore , (1/2,1) is on the graph of y = log1/2x?

Answer:
0.8594
Step-by-step explanation:
Let a denote the event of forgetting to shut off machine and b be the event of being defective.
-A foreman forgets to shut off machine 55% of the time.
-If he forgets, 15% of molds are defective.
-If he does not, 3% of molds are defective.
#The probability that he forgot to shut off the machine is calculated as:
P(a and ~b)=0.55(1-0.15)=0.4675
P(~a and b) = (1-0.55)*0.03=0.0135
P(~a and ~b) = (1-0.55)*(1-0.03)=0.4365
#Conditional probability is defined as:
Hence, the probability that the foreman forgot to shut off the machine the previous night is 0.8594
