There.
Answer:
B
Step-by-step explanation:
the question says -12x ≤ -72.the sign ≤ means less than or equal to. so we will divide both sides by -12 to get the value of x. and that wil give us x ≤ 6, the sign did not change because we used a sign common to both sides to divide it. that is slso the reason why we had a positive value.
Stratified random sampling is a method of sampling that involves the division of a population into smaller groups known as strata. In stratified random sampling or stratification, the strata are formed based on members' shared attributes or characteristics. Stratified random sampling is also called proportional random sampling or quota random sampling.
By contrast, simple random sampling is a sample of individuals that exist in a population; the individuals are randomly selected from the population and placed into a sample. This method of randomly selecting individuals seeks to select a sample size that is an unbiased representation of the population. However, it's not advantageous when the samples of the population vary widely.
The answer is24. Explenation: 2 x (49.5 - 37.5)
2 x 12=
24
Completing the square goes back to pythagorean thm
but the way u do it, u want to find a value that enable u to take sqrt of both sides and solve
x^2-8x+3=0
x^2-8x=-3
we need (x-4)^2 so add 16
(x-4)^2=-3+16
(x-4)^2=13
x-4=sqrt13
x=4(+/-)sqrt13
