The first thing we will do for this case is to define the following variable:
x = real number.
We then have the following sentence:
"Five more than the product of a number and 9 is equal to 6"
The equation sought is:
9x + 5 = 6
Answer:
An equation for the sentence is:
9x + 5 = 6
X = 9
Add both values 7 + 2 = 9, which is x.
9 - 2 = 7.
Answer:
500=120+60
Variable would either be M or D For 60
Step-by-step explanation:
Round 296 up to 300 and then divide 300 by 4 mentally. Answer: 75. Which is a more reasonable partial quotient, 50 or 70?
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.
