Answer:
The correct answer is 70.
Step-by-step explanation:
Since they got the same answer we have the equation:
(a + 3)a + 6 = a + 3(a + 6)
a^2 + 3a + 6 = a + 3a + 18
a^2 + 3a - 3a -a + 6 - 18 = 0
a^2 - a - 12 = 0
(a - 4)(a + 3) = 0
So a = 4 or -3.
As a is given as positive we take a = 4.
The correct numerical value =
(4 + 3)( 4 + 6)
= 70.
Answer:
Population: all of the students at the town's high school
Sample Examples:
- An equal fraction of students from each grade.
- Every 5th student arriving at the school at a certain day.
Step-by-step explanation:
The population of a survey is the group whose data is desired.
If Alan wants to determine the type of art preferred by students at the town's high school, the population of his survey is all of the students at the town's high school.
It might not be realistic to interview every student, which is why samples are used. Samples must be designed in a way that represents the whole population without bias. One way to do it would be to survey an equal fraction of students from each grade. Another alternative, is to randomly survey every 5th student arriving at the school at a certain day.
This would represent a negative correlation, as there is an inverse or opposite relationship existing between the 2 variables. The amount of training and the calls received.
As one variable increases the other decreases.

Answer:
25.000
Step-by-step explanation:
With only this information, the answer would be 25000, if there are 100 light bulbs on EACH strand, then we only have to multipy the number of strands by the number of light bulbs. So 250×100=25000
