Answer:
2x² + 3x
Step-by-step explanation:
Using distributive property, you can multiply the variable outside the parenthesis to both terms inside the parenthesis:
x(2x + 3) = 2x(x) + 3(x) or 2x² + 3x
When multiplying with the same base, you will add the exponents.

Answer: C
Step-by-step explanation:
Factor 196k
196k=2*2*7*7*k
we need to get something like x^3
hmm
we right now have
(2*7)^2
if we multiply that by (2*7)^1, we can beg (2*7)^3,
therefor k=2*7=14
tha tnumber is 14
or
if k can be any number
k can be 1/196, to make it 1, and 1 is a perfect cube
or
my bro had an epic idea: what if k is negative
the cube root of a negative number is negative
so the smallest one would be negative infinity or something
I think the answer you're looking for is k=14
Answer:
a) True
b) Parameter
Step-by-step explanation:
We are given the following in the question:
An accounting professor wants to know the average GPA of the students enrolled in her class.
Population:
- It is defined as the collection of all variables of interest.
- A sample of individuals of interest is drawn from a population.
For the given case
Individuals of interest:
Students enrolled in accounting class
Population of interest:
Students enrolled in accounting class
Characteristic of interest:
Average GPA of the students enrolled in her class.
a) The population is all students enrolled in the accounting class.
The given statement is true as it contains all the observation of all the individuals of interest.
b) The computed average GPA of all the students enrolled in the class is 3.29
Statistic is a descriptive measure that describes a sample where as a parameter is a measure that describes the population.
Since 3.29 is the average of all the students enrolled in her class that is the average GPA of population.
Thus, 3.29 is a parameter.
