Utilize the! operation to determine the count of combinations.

8!/5! = 40,320/120 = 336

There are 345 students at a college who have taken a course in calculus, 212 who have taken a course in discrete mathematics, an
AnnZ [12381]

Answer:

There are 369 students who enrolled in either calculus or discrete mathematics.

Step-by-step explanation:

I'll create a Venn diagram to illustrate these figures.

Let’s define:

A represents the count of students who completed calculus.

B stands for those who took discrete mathematics.

We have the following:

A = a + (A \cap B)

Here, a denotes the students who studied calculus exclusively, while A \cap B represents those who took both subjects.

Using the same reasoning:

B = b + (A \cap B)

There are 188 students taking both calculus and discrete mathematics.

This implies that A \cap B = 188

A total of 212 students studied discrete mathematics.

<pBased on this, B = 212

345 students have attended a calculus course.

<pSo, from this information, A = 345

We find the total number of students who took either calculus or discrete mathematics.

(A \cup B) = A + B - (A \cap B) = 345 + 212 - 188 = 369

A total of 369 students participated in either calculus or discrete mathematics.

the vertex form of a function is g(x) = (x – 3)2 9. how does the graph of g(x) compare to the graph of the function f(x) = x2? g
Inessa [12570]
The vertex of the graph for the function g(x) = (x- 3)^2 + 9 is located 3 units to the right and 9 units upwards compared to the vertex of the function f(x) = x^2.
