The correct response that would be expected based on the probability information is 164
<h3>How to depict the values?</h3>
From the information, there were 352 trials that were made and we're correct 164 times.
Therefore, the correct response that would be expected is 164.
The success rate will be:
= 164/352
= 0.466

Answer:
y - 9 = - 3(x - 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (2, 9), thus
y - 9 = - 3(x - 2) ← in point- slope form
Average (mean) = (sum of all the data) / (# of data)
sum of all the data = (average)(# of data)
Thus for 100 students with an average of 93,
sum of all data = (93)(100) = 9300
and for 300 students with an average of 75,
sum of all data = (75)(300) = 22500
Therefore you would expect the overall average to be
(9300 + 22500) / (100 + 300) = 79.5 %
Now if there are x # of advanced students and y # of regular students, then
x + y = 90 (total # of students) and 93x + 75y = 87(x + y) (overall average)
The second equation can be simplified to x - 2y = 0
Subtracting the two equations yields
x = 60 and y = 90
Therefore you would need 60 advanced and 30 regular students.
The area of a regular polygon<span> is given by the formula which is expressed as:
</span>area = (½)(apothem<span>)(perimeter)
</span>
We calculate as follows:
area = (½)(7<span>)(7.2 x 5)
</span>area = 126 square units
Hope this answers the question.
