There are 39 counters in a bag.
14 of the counters are red.
The rest of the counters are blue,
One of the counters is taken at random.
What is probability that the counter is blue.

There fore the probability that the counters are blue is

Step-by-step explanation:

There are a total of 14 red counters and 39 in total. The total of red counter can be represented as a fraction of . To find out the number of blue counter we subtract 14 from 39. This gives us 25. This is . Therefore the probability that the counters are blue is

25/39

Step-by-step explanation:

The total is 39

Red=14

So to determine blue,it will be

39-14=25

So blue will be 25

So to determine the probability for picking blue

It will be

25/39

Since there's no common number that can divide the two

The final answer is 25/39

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
