Answer:

P (odd number or number greater than 4) = 4/6 = 2/3

Step-by-step explanation:

The solution set { 1,2,3,4,5,6}

Odd numbers are 1,3,5

Numbers greater than 4 are 5,6

Notice that 5 is repeated. We can only count it once

There are 4 answers that meet the criteria (since we can only count 5 once)

THE RATIO OF ANNUAL INCOMES OF A AND B IS 4 :3 AND THEIR ANNUAL EXPENDITURE IS 3 :2 IF EACH OF THEM SAVES SHILLINGS 1000 A YEAR

pickupchik [31]

Answer:

Annual Income of A= $4x=4*1000=4000$

and

Annual Income of B= $3y=3*1000=3000$

Step-by-step explanation:

Given Data:

Ratio of annual income of A and B=4:3

Ratio of expenditures of A and B=3:2

Saving of A and B=1000

Required: Annual Income of A and B=?

Solution:

If ratio of income of A and B is 4:3

then let Income of A= $4x$ and Income of B= $3x$

If ratio of expenditure of A and B is 3:2

then let expenditure of A= $3x$ and expenditure of B= $2x$

Therefore,

$4x-3x=1000$ ........... $Eq(1)$

and $3x-2x=1000$ .......... $Eq(2)$

subtracting Eq(1) and Eq(2), we get

$4x-3y=1000\\-(3x-2y)=1000\\......................\\x-y=0$

$x=y.....Eq(3)$

putting $x=y$ in Eq(1), we get value of $x$ as

$4x-3x=1000$

$x=1000\\thus, y=1000 \\$ because x and y are equal in Eq (3)

Now, Annual Income of A= $4x=4*1000=4000$

and Annual Income of B= $3y=3*1000=3000$

Given the functions f(x) = 10x + 25 and g(x) = x+8, which of the following functions represents f(g(x)] correctly?

victus00 [196]

Answer:

g(x + 8) = 10x + 105 wherever you see it among your answers.

Step-by-step explanation:

I think I have enough here that I can answer the question, but you should always put in your givens.

f(x) = 10x + 25 Put g(x) where you see x in f(x)

f(g(x)) = 10(g(x) + 25 Put the value for g(x) where you see g(x)

f(x+8) = 10(x + 8) + 25 This might be the answer

From here it is a guess.

f(x+8) = 10x + 80 + 25 Combine the like terms

f(x+8) = 10x + 105
