The ratio of blue tacks to red tacks on the bulletin board is 3 to 5. There are 50 red tacks. How many blue tacks are on the boa

algol13

3:5=x:50

Therefore 5 ×x = 50

x = 10

Therefore 3 × 10 = 30

therefore 30 blue pens

proof = 30 blue + 50 red= 3+ 5

therefore 80 = 8x

More than three-quarters of the nation’s colleges and universities now offer online classes, and about 23% of college graduates

RUDIKE [14]

Answer:

0.1997 or 19.97%

Step-by-step explanation:

Have taken course online (H) = 23%

Have NOT taken course online (N) = 77%

Have taken course online and don't believe they provide same value (H&D) = 61%

Have NOT taken course online and don't believe they provide same value (N&D) = 73%

The probability that a student has taken a course online given that she does not believe that online courses provide the same educational value as one taken in person is;

$P(H|D)=\frac{P(H)*P(H\&D)}{P(H)*P(H\&D)+P(N)*P(N\&D)}\\P(H|D)=\frac{0.23*0.61}{0.23*0.61+0.77*0.73}\\P(H|D)=0.1997$

There is a 0.1997 or 19.97% chance that she has taken an online course before.

Is 25 to 16 proportional to 5 to 4

e-lub [12.9K]

Yes 25 to 16 is proportional to 5 to 4.
This is because 25 can be simplified to 5 by dividing 25 by 5.
In the same way 16 can be simplified to 4 by dividing it by 4.

It results in the same proportion which is 5 to 4.
