Remark
Using brackets, as the question has, each of the minus signs is part of the 4. That means you have 2 minus signs in total. They are multiplied together.
Two minus sign's = a plus.
Argument
D is wrong.
The power is not made minus. That would be an entirely different problem. The power and the base have been interchanged. So D has 2 mistakes.
B is also wrong for the same reason.
The power and base have been interchanged. The fact that there are or are not brackets does not make any difference.
A is wrong.
There is only one minus sign given. That cannot happen when there were two to start with.
Answer C.
The two minus signs are preserved. The 2 as a power affects both minus signs.
affects both of them.
Answer:
Gender, car
Step-by-step explanation:
Give the data above :
The categorical variables are : Gender and Car
The Gender are car variables represents non numeric variables written as strings and as such does not allow for numeric calculations such as addition, subtraction and so on, they are instead used to classify the observations in the data into discreet groups, the gender variable separates observations into Male and Female classes while, the car variable separates cars driven into distinct classes denoting the name of cars driven by each observation in the data. The other variables are of quantitative nature as they allow for numerical computation of the data values.
Answer:
The error is:
He multiplied the dividend by 100 instead of 10
Step-by-step explanation:
∵ 1.926 ÷ 0.9 ⇒ means
1.926 = 1926/1000 ⇒ dividend
0.9 = 9/10 ⇒ divisor
*
÷ 
× 
× 
∵ 1926/100 = 19.26 ⇒ dividend
∴ 19.26 ÷ 9 = 1926/100 ÷ 9
19 ÷ 9 = 2 with remainder 1/9
12 ÷ 9 = 1 with remainder 3/9
36 ÷ 9 = 4 no remainder
∴ The quotient is 214/100 = 2.14
