Answer:
21.6 hours
Step-by-step explanation:
Hypothesis testing allows to identify a event test. The correct order of the steps of a hypothesis test is given following
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
These steps are performed in the given sequence to test a hypothesis.
The principal tests the hypothesis with a mean of 21.6 hours for the determination of average amount of time spent watching television.
<u><em>Answer:</em></u>
Section 1: 5.59%
Section 2: -2.16%
Section 3: -10.82%
Section 4: -6.54%
Section 5: -2.16%
Section 6: 7.86%
<u><em>Explanation:</em></u>
<u>The formula to calculate the percent change in mass is given as:</u>
<u>1- Section 1:</u>
Old mass = 7.83 g and New mass = 8.268 g
5.59%
<u>2- Section 2:</u>
Old mass = 7.4 g and New mass = 7.24 g
-2.16%
<u>3- Section 3:</u>
Old mass = 7.3 g and New mass = 6.51 g
-10.82%
<u>4- Section 4:</u>
Old mass = 7.49 g and New mass = 7.0 g
-6.54%
<u>5- Section 5:</u>
Old mass = 7.4 g and New mass = 7.24 g
-2.16%
<u>6- Section 6:</u>
Old mass = 7.89 g and New mass = 8.51 g
7.86%
Hope this helps :)
Answer:
f=7/5x+27/5
Step-by-step explanation:
you just have to divide both sides by -5
The answer is 17/5. You have to take the whole number, multiply that by the denominator. Then add that number to the numerator to get the new numerator and the denominator stays the same as before (5)
