Answer:

2. 1 / a^2

3, 1

4. - 1

Step-by-step explanation:

Formulas : -

x^y / x^z = x^( y - z )

x^-y = 1 / x^y

x^y / x^y = 1

2.

a^2 / a^4

= a^( 2 - 4 )

= a^-2

= 1 / a^2

A survey was done to determine the effect of students changing answers while taking a​ multiple-choice test on which there is on
Umnica [9.8K]

Answer:

6% of the changes were from incorrect to​ incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65​% of the changes were from incorrect answers to correct

29​% were from correct to incorrect

P% were from incorrect to incorrect

So

65 + 29 + P = 100

P = 100 - 94

P = 6

6% of the changes were from incorrect to​ incorrect

Parking at a university has become a problem. University administrators are interested in determining the average time it takes
Vikentia [17]

Answer:

<h2>In this particular case,the target population of interest to the university administration constitutes the university students.</h2>

Step-by-step explanation:

  • The university administration is interested to conduct a statistical study to identify the average or mean time taken by the students to find a vacant parking spot.
  • Therefore,the research topic here is the average time taken by the university students to find parking spot. The administrator collects an inconspicuous sample of 240 samples from the target population of the study,which is the overall student population of the university.
  • The sample collected by the university administration is used to observe the average or mean parking time by the university students.

The two triangle­shaped gardens are congruent. Find all of the missing side lengths and angle measures. Show any necessary work
pantera1 [17]
The two figures are in the file attached.

Congruency means that all the respcetive sides and angles are equals.

Then, the three angles are :

y = 38°

x = 90°

w = 180° - 90° - 38° = 52


The three sides are:

z= 10yd
v= 7.9yd
u=6.2yd


You have all the measures as a function of yd, but you do not have any information about yd, then it is not possible to find the real lenghts.

All you can tell is that the sides obey Pythagoream theorem:

u^2 + v^2 = z^2   

But that is not enough to find one side, because you do not know any of them.

For example if you apply Pytagorean theorem you cand do"

(7.9yd)^2 + (6.2)^2 = (10yd)^2

but that cannot be solved for yd, because they are factors of all the terms in both sides, which mean that they cancel to obtain:

(7.9)^2 + (6.2)^2 = (10)^2, which is not any new information.

Also you can think about sine theorem, but it does not help, because you also need one side.


Then you only can tell the missing angles, as I have shown, but not the misssing lengths.
