Answer:
n = 84
Step-by-step explanation:
18 + 3 = 21, so that means the quotient of the number and 4 is 21.
21 * 4 = 84
CHECK:
84 / 4 = 21
21 - 3 = 18
When studying populations, it is very difficult to evaluate all individuals, whether by size, difficulty, budget, etc., to solve this, the statistical inference deals with all the mathematical procedures that allow drawing conclusions for the population, with a degree of calculable error, from a sample of it.
Answer
C. Is the process of drawing inferences about the population based on the information taken from the sample
The <em><u>correct answer</u></em> is:
b.. Population distribution applies only to animals..
Explanation:
Population distribution can be applied to animal populations, but it can also be used when studying human populations as well.
Answer:
i) move constants to the right-hand side and change its sign
ii) subtract the numbers
iii) add (12/2)² to both sides of the equation
iv) using a²-2ab+b²=(a-b)² , factorize the expression
v) calculate the value
vi) reduce the fraction
vii) solve the equation for x
1) first value of x
2) second value of x
Okay, so you first make this proportion...
x=12x(4/6)=8 laps
answer: 8 laps
