As a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses

Sergeeva-Olga [200]

Answer:

We have 252 different schedules.

Step-by-step explanation:

We know that as a freshman, suppose you had to take two of four lab science courses, one of two literature courses, two of three math courses, and one of seven physical education courses.

So from 4 lab science courses we choose 2:

$C_2^4=\frac{4!}{2!(4-2)!}=6$

So from 2 literature courses we choose 1:

$C_1^2=\frac{2!}{1!(2-1)!}=2$

So from 3 math courses we choose 2:

$C_2^3=\frac{3!}{2!(3-2)!}=3\\$

So from 7 physical education courses we choose 1:

$C_1^7=\frac{7!}{1!(7-1)!}=7$

We get: 6 · 2 · 3 · 7 = 252

We have 252 different schedules.

4. In the diagram below, ZABD = (4x + 3)º and DBC = (7x-6)º.

blsea [12.9K]

Answer:

Step-by-step explanation:

a) ∠ABD + ∠DBC = 90°

4x - 3 + 7x - 6 = 90

4x + 7x - 3 - 6 = 90

11x - 9 = 90

11x = 90 + 9

11x = 99

x = 99/11

x = 9

∠ABD = 4*9 - 3 = 36 - 3 = 33
