Answer:
D. all of the above is the correct answer.
Explanation:
Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
<h3>What is the discrete probability distribution?</h3>
Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.

Answer:
B. A harmful compound can become harmful when its elements are seperated.
Explanation:
In the question, common table salt, NaCl was the illustration.
NaCl is a crystalline solid whjch has different benefits like for preservation, add taste to foods etc. NaCl is generally consumed by humans daily and is found readily. This goes to show that NaCl is a harmless compound but the individual elements that is, Soduim and Chlorine gas,
2Na + Cl2 --> NaCl
Soduim metal is a reactive and unstable element with 1 (valence) electron in its outer shell. Hence why the reaction of sodium strips with water is explosive.
Chlorine gas is very poisonous, unstable as well as reactive because of the 7 (valence) electrons in its outermost shell.

<em>What values of c and d would make the following expression represent a real number? i(2 + 3i)(c + di)
</em>
<em>choices: A)c = 2, d = 3 B)c = –2, d = 3 C)c = 3, d = –2 D)c = –3, d = –2</em>
<em />
<em>Option D</em><em> is correct. </em> The value of c and d for the expression to be real are -3 and -2 respectively
Given the expression

Expand the expression

Collect the like terms

For the resulting function to be real, then the imaginary part must be zero i.e.

If d = -2, then;

Hence the value of c and d for the expression to be real are -3 and -2 respectively.

The handling surcharge for items that are fragile and insurance cost for items that have a high value are two different terms that can be filled in different cells on the Excel Sheet. On the Excel sheet, the excel formula that can be used to calculate the value of the corresponding item is:
- = SUMIF (handling surcharge for fragile items: insurance cost for high_value items, criteria, [sum_range])
An Excel sheet is a spreadsheet that is used for calculating arithmetic operations, statistical calculations, and graphical analysis. In an Excel sheet, simple commands are input by using the Excel Formulas.
For the given example; the excel formula to be used is:
- = SUMIF (handling surcharge for fragile items: insurance cost for high_value items, criteria, [sum_range])
The formula is therefore being copied and pasted down in the subsequent cells below to determine the values of other corresponding items.
Therefore, we can conclude that the excel formula to be used can be seen in the format outlined above.
