Answer:
Step-by-step explanation:
4n - 6m = - 2 Subtract 4n from both sides.
4n-4n - 6m = -2-4n
-6m = - 2 - 4n Divide by - 6
-6m/-6= -2/-6 -4n/-6 Do the division
m = 1/3 + 2n/3
The signs change because each term has 2 minus signs. 2 minus signs make a plus. Or both minus signs cancel.
Answer:
The null hypothesis would say that class size has no effect on students learning.
Step-by-step explanation:
Null hypothesis is a type of hypothesis that is used in statistics which proposes that there is no difference between a certain characteristic of a population or the data - generating process.
Now, in this question,the school district is considering increasing class size in the elementary schools but we want to check whether larger classes may have a negative effect on students learning.
Thus, the null hypothesis would reject this claim of larger classes having negative effect on students and say that class size has no effect on students learning.
Answer: reversed.
Step-by-step explanation:
1. By definition, when you multiply or divide both sides of an inequality by the same negative number, then the direction of the inequality symbol must be reversed.
2. To understand this better, let's write the inequality shown below:
The symbol > means "greater than".
If you multiply both sides of the inequality by -1, you obtain:
(This is false, because -4 is not greater than -2)
But, if the symbol is reversed, then:
(This is true because -4 is less than -2)
The symbol < means "less than".
