Answer: There is decreased by 1\dfrac{5}{8} points in stock after three days and negative integer is used to represent.

Step-by-step explanation:

Since we have given that

Point decreased by on Monday = \dfrac{1}{2}

Point decreased by on Tuesday = \dfrac{3}{4}

Point decreased by on Wednesday = \dfrac{3}{8}

So, total decreased in these three days are

\dfrac{1}{2}+\dfrac{3}{4}+\dfrac{3}{8}\\\\=\dfrac{4+6+3}{8}\\\\=\dfrac{13}{8}\\\\=1\dfrac{5}{8}

hence, there is decreased by 1\dfrac{5}{8} points in stock after three days and negative integer is used to represent.

at a certain university, 23% of students will graduate with a math degree, 31% will graduate with a computer science degree and
Tpy6a [65]
<h3>Answer:  B) 47%</h3>

Work Shown:

A = event that the person has math degree

B = event that the person has a computer science degree

P(A) = 0.23, since 23% of the people have a math degree

P(B) = 0.31, similar reasoning as above, just different number

P(A and B) = 0.07

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.23 + 0.31 - 0.07

P(A or B) = 0.47

The decimal value 0.47 then converts to 47% after moving the decimal 2 spots to the right.

There's a 47% chance that we pick someone who has a math degree or a computer science degree (or both).

It might help to set up a venn diagram to see why that formula above works.
