Are we assuming there are the same number of students total in both classes for both semesters
1st semester 2 art: 7 gym
2nd semester 5 art: 4 gym so 75 =5/9 75/5=15 for every 1 in the ratio is is = 15 students so 1st semester 30 art 105 gym 2nd semester 75 art 60 gym both have 135 total in both classes both semesters hope i helped -J
Answer:
The correct answer is D) areas, probability, and relative frequencies
Step-by-step explanation:
This is because each of these terms refers to an amount of space surrounding the mean on the normal distribution curve. Each of them let's us know how likely a spot is to have a value within it.
The z-score would not fit this as it identifies the value and how far away a single spot on the graph would be.
Answer:
x = - 2
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= x² - 2x + 6x + 4
= x² + 4x + 4
Equating to zero
x² + 4x + 4 = 0
(x + 2)² = 0
x + 2 = 0
x = - 2
Answer:
B. BE≅DA
Step-by-step explanation:
CPCTC = corresponding parts of congruent triangles are congruent.
Triangles BAE and DEA are congruent, then
So option B is correct.
All other options cannot be proved using CPCTC of triangles BAE and DEA.
