Distance of Jupiter to sun:
7.8*108=842.4
Distance of Saturn from sun:
1.5*109=163.5
difference:
842.4-163.5=678.9
-30-5x=-4x-6(5+4x)
First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x
Then, you can add like terms to get -30-5x=-30-28x
Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x
Finally, you divide both sides by -23 to get 0=x
Answer:
Simple random sampling
Step-by-step explanation:
In this example, the teacher takes a random 40-student sample from the whole population of students. The fact that the students are alphabetically order does not interfere in the sampling process since students are picked at random. Therefore, the teacher applied the simple random sampling method.
This method provides an unbiased representation of the population.
The answer would be y=-2x-4
