Answer: Infinite solutions.
Step-by-step explanation:
Plug the value of y into the second equation.
Add 12 on both sides.
Add 4x on both sides.
Take out the factor of 3 from both numbers
(69)/3 = 23
(12)/3 = 4
69 + 12 can be rewritten as 3(23 + 4)

Answer:
The population is the set of all the elements. And the sample is a subset of the population.
Step-by-step explanation:
The population is the set of all the elements. And the sample is a subset of the population.
The sample is used to make conclusions regarding the population.
A poll is conducted from the target population to determine the general opinions of the individuals of that population.
The basic method of polling is to select a few thousand individuals from the population and ask their opinions on a certain subject.
The poll will result usually in two values, the proportion of individual in favor and the proportion of individual not in favor.
Consider the example below.
The polling done to determine the favorability of the new brand of tea. The polling was done using a few hundred members of the tea drinking community of a country. The poll resulted as follows:
In favor = 72%
Not in favor = 28%
The population is the entire tea drinking community of a country.
In this case the sample consist of few 100 people of the tea drinking community of a country.
Answer: C. 17.5 feet
Step-by-step explanation:
The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine the height of the wall, we would find BC by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
18^2 + 4.5^2 + BC^2
BC^2 = 324 - 20.25 = 303.75
BC = √303.75 = 17.5 feet.
