Answer:
C. But
Explanation:
Boolean operators are the operators that may have only two outputs which are True/False, On/Off and 1/0.
"But" can also be the example of Boolean operator. It is used in the meaning of "except" or "other than".
In Boolean operators "But" can be used as "AND" operator.
for example
<em>I am busy but I will go.</em>
In above example but is used as and which is combining two oposite statements. as
I am busy and I will go.
Both statement oppose each other, so to make sense in English "But" is used.
Answer:
When working with a file, <u>stabilize</u> the blade in a vis or against a solid surface such as a work bench to avoid injury and to ensure an even stroke
Explanation:
The file can be used to sharpen a blade to increase the effectiveness of the blade. In order to properly sharpen a file in a safe manner, the blades to be sharpen, which ae usually relatively flexible as compared to the file, should be made stable during the repetitive forward and backward notion of the file, for safety, to avoid being injured by the recoil of the blade, and also to ensure that the stroke is evenly applied to the blade.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
