The expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.
<h3>What is stated as the
equivalent expression?</h3>
- Equivalent expressions have been expressions that perform the same function despite their appearance.
- If two linear algebra expressions are equivalent, they have the same value when the variable is set to the same value.
For the given question, the expression is stated as-
Negative 7 over 6 times t plus 4 over 9 end quantity minus expression quantity negative 5 over 12 times t plus 2 over 3 end quantity
This can be written as;
= -7t/6 + 4/9 - (-5t/ 12 + 2/3)
Simplify the expression as;
= -7t/6 + 4/9 + 5t/ 12 - 2/3
Re arrange the numbers
= -7t/6 + 5t/ 12 - 2/3 + 4/9
Combine the variables and constant separately.
= -9t/12 - 2/9
This can be written in words as- negative 9 over 12 times t minus 2 over 9.
Thus, the expression is equivalent to the given expression is: negative 9 over 12 times t minus 2 over 9.

Answer:
If we define the random variable X ="time spend by the students doign homework"
And we want to tes t is students spend more than 1 hour doing homework per night, on average (alternative hypothesis), so then the system of hypothesis for this case are:
Null hypothesis: 
Alternative hypothesis: 
And they wnat to use a sample size of n = 100 and a significance level of 0.05
Step-by-step explanation:
Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Solution to the problem
If we define the random variable X ="time spend by the students doign homework"
And we want to tes t is students spend more than 1 hour doing homework per night, on average (alternative hypothesis), so then the system of hypothesis for this case are:
Null hypothesis: 
Alternative hypothesis: 
And they wnat to use a sample size of n = 100 and a significance level of 0.05
