1/7f- 5 1/2= 9/14. what is f?

1 answer:

8 0

To solve this equation, we have to isolate the variable f, or get it alone on one side of the equation.

1/7f - 5 1/2 = 9/14

To do this, we need to add 5 1/2 to both sides of the equation to 1) cancel out the - 5 1/2 on the left side of the equation, and 2) maintain equality both sides of the equation.

1/7f - 5 1/2 + 5 1/2 = 9/14 + 5 1/2

1/7f = 6 2/14

Next, we have to divide both sides by 1/7, to get rid of the coefficient of f on the left side of the equation.

1/7f ÷ 1/7 = 6 2/14 ÷ 1/7

f = 43

Therefore, the the value of f is 43.

Using translation concepts, the equation for function g(x) given in the graph is:

$g(x) = 2^{x + 2}$

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The parent function for this problem is given as follows:

$f(x) = 2^x$

From the graph, function g(x) was shifted 2 units left, hence x -> x + 2 and the definition is:

$g(x) = 2^{x + 2}$

In the game of Keno, a player starts by selecting 20 numbers from the numbers 1 to 80. After the player makes his selections, 20

DiKsa [7]

The percentage of winning if 20 winning numbers are randomly selected from numbers 1 to 80 is 12.48%.

Given There are 80 numbers from which 20 numbers are selected randomly in a game of Keno by player and after selection of 20 winning numbers again 20 numbers are selected and player wins if the player has correctly selected 3,4,or 5 of the 20 winning numbers.

Probability is the chance of happening an event among all the events possible.

Probability of winning is calculated as under:

Probability= $C(20,3)C(60,17)/C(80,20)$

We have taken C(20,3) because player will win if 5 numbers are selected from 20 winning numbers.

We have taken C(60,17) because after selection of 20 numbers 60 numbers will left from 80 and after winning from 3 numbers 17 numbers left and from total 80, 20 numbers are taken.

=C(20,3)C(60,17)/C(80,20)

=(20!/3!17! * 60!/17!43!)/80!/20!60!

=1140*387221678682300/35353161422121743200

=12.48%

Hence the probability of winning is 12.48%.
