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.

4/3y=48<br><br>solve for y<br><br>simplify answer as much as posible
Helga [31]
<h2>If you mean :</h2>

\frac{4}{3y}  = 48 \\

Inverse both sides

\frac{3y}{4}  =  \frac{1}{48}  \\

Multiply both sides by 4

4 \times  \frac{3y}{4}  = 4 \times  \frac{1}{48}  \\

3y =  \frac{4}{48}  \\

3y =  \frac{4 \times 1}{4 \times 12}  \\

3y =  \frac{1}{12}  \\

Divide both sides by 3

3y \div 3 =  \frac{1}{12}  \div 3 \\

y =  \frac{1}{12}  \times  \frac{1}{3}  \\

y =  \frac{1}{36}  \\

_____________________________________________

<h2>If u mean : </h2>

\frac{4}{3} y = 48 \\

Multiply both sides by the 3

3 \times \frac{4}{3} y = 3 \times 48 \\

4y = 3 \times 48

Divide both sides by 4

4y  \div 4 = 3 \times 48 \div 4

y =  \frac{48 \times 3}{4}  \\

y =  \frac{4 \times 12 \times 3}{4 \times 1}  \\

y = 12 \times 3

y = 36

Point A is located at (2,9) and is reflected in the x-axis. What is the location of Point A'?
elena-14-01-66 [18.8K]

Answer:

(2,-9)

Step-by-step explanation:

A reflection around the x-axis implies keeping the x-coordinate as it its (no change in its numerical value), while using the exact opposite of the numerical value of the y coordinate.

In our case then:

X coordinate unaltered = 2 stays as 2

Y coordinate opposite of the original value: 9 changes to "-9"

Therefore the coordinates of point A' are: (2,-9)
