Answer:

x=-32.73\,,\,y=85.43

Step-by-step explanation:

Given: y=3.58x+202.6\,,\,y=2.3x+160.7

To find: value of x and y

Solution:

y=3.58x+202.6\,\,(i)\\y=2.3x+160.7\,\,(ii)

From equation (i) and (ii),

3.58x+202.6=2.3x+160.7\\3.58x-2.3x=160.7-202.6\\1.28x=-41.9\\x=\frac{-41.9}{1.28}=-32.73

Put x=-32.73 in (i)

y=3.58(-32.73)+202.6\\=-117.17+202.6\\=85.43

Assume that advanced students average 93% on an achievement test and regular students averaged 75%. If 100 advanced students and
Lemur [1.5K]
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.

Please help!!!! I don’t know which one!
Daniel [21]

The correct answer is the first choice. You can determine which angles are congruent by looking at the corresponding angles (angles that are in the same position) on the similar trapezoids). The angles would be congruent even though the shapes are not the same size.
