Answer:
fractions form- x= 5/6
decimal form- x=0.83
Step-by-step explanation:
The <em><u>correct answer</u></em> is:
At least 7 times.
Explanation:
Since 10% of the water in the jug is removed each time, this means that 100-10=90% of the water remains.
After two times, we would have 0.9(0.9) = 0.81 = 81% of the water; each time she pours, the number of times 0.9 is multiplied by itself changes. This makes this an exponential inequality (it is not an equation, as we want "less than half of the water"):
To solve this, we will use logarithms:
Answer:
(-1)(11)(3)(5)
Step-by-step explanation:
First off: -165 separates into the factors (-1) and (165). Next, we divide 165 by 15, obtaining 15(11).
So far, we have (-1)(11)(15).
15 is still factorable. We get:
(-1)(11)(3)(5), which is the desired prime factorization of -165.
Answer:
Option b) Sample
Step-by-step explanation:
We are given the following in the question:
Survey:
356 surveys on television-viewing habits of American adolescents.
Result:
Average of 3.1 hours per day.
Population and sample:
- Population is a collection of all the possible observation of individuals or variable of interest.
- A sample is always a part of the population.
- It is a subset of population.
For the given survey, those who responded to the survey forms a a sample as it is a part of 356 surveys that is a subset of population.
The correct answer is
Option b) Sample
