Answer: a) 2 b)1  c)1/3 d)5/4

Step-by-step explanation:

Hi to solve this equation we simply have to replace the variable with the number given, and then isolate the variable.

  • 5x, if x= 2/5

5 x 2/5 = 10 /5 = 2

  • 5/x,if x =5

5/5= 1

In this case after replacing the number we have to simplify it.

  • 2y-1, if y =2/3

2 (2/3) -1 =

4 /3 -1 =

4/3 -3/3 = 1/3

In this case, to add fractions first we have to multiply the top and bottom numbers of the second fraction by 3, to have the same denominators.  

  • h+3/4, if h = 1/2

1/2 + 3/4 =

2/4 +3/4 = 5/4

Feel free to ask for more if it´s necessary or if you did not understand something.

5x if x= 2/5 . 5/1x 2/5= 10/5= 2

5/x = 5/5= 1

8/3_ 1 = 8/3- 3/3= 5/3

1/2+ 3/4 = 2/4+3/4= =5/4

Answer:

24% chance

Step-by-step explanation:

First, find the total number of graduates in the table, that number is 2610, that will be your numerator.

You will look at the table for the total number of students, that is 10730, that will be the denominator.

Now divide the smaller number/numerator (2610) by the larger number/denominator (10730)

\frac{2610}{10730} = 0.2432432...

Then, multiply by 100 to get the percentage: 24.32432...%

Now, round to the nearest percentage: 24%

One ballispicked at random from a box containing 3redballs and 1green balls. If X is the number of redballs picked, find the pro
Paladinen [302]

Answer:

P(X = 0) = 0.25

P(X = 1) = 0.75

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The probability distribution of X.

3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.

P(X = 0) = \frac{1}{4} = 0.25

P(X = 1) = \frac{3}{4} = 0.75

How do I solve this?
Olin [163]
Well if it is 1 inch per 100 feet, then we already know that 600 feet is 6 inches on the map. Now the 4 is where it gets trickier. Since it's dividing it by 100 each time, you take 4 and divide it by 100 which is 0.04. Therefore, your answer is 6.04 inches on the map.

Find the measure of the missing angle.<br> 34°
Digiron [165]

The answer is 56.

As you can see, the triangle given is a right angle, meaning it is 90 degrees. To find the missing angle, we can solve 90 - 34 to get 56.

hope this helps !! have a nice day :))
