Stacie paid $13.25 for new earphones. The price she paid included a sales tax of 6%.
GrogVix [38]
Let us assume the original cost of the earphones = x dollars
Then
x * (106/100) = 13.25
x = 13.25 * (100/106)
   = 1325/106
   = 12.50 dollars
So the actual cost of the earphones was $12.50. The correct option among all the options that are given in the question is the second option or option "B".

A roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green. In each round of the game, a ba
vlabodo [156]

Answer:

Of the 777 rounds of the game in about 368 the ball will land in a red slot.

Step-by-step explanation:

Since a roulette wheel has 383838 slots, of which 181818 are red, 181818 are black, and 222 are green, and in each round of the game, a ball is tossed in the spinning wheel and lands in a random slot, supposing we watch 777 rounds of this game, to determine the approximate number of rounds where the ball lands in a red slot, the following calculation must be performed:

383838 = 100

181818 = X

181818 x 100/383838 = X

18,181,800 / 383838 = X

47.3684 = X

100 = 777

47.3684 = X

47.3684 x 777/100 = X

36,805.24 / 100 = X

368.05 = X

Therefore, of the 777 rounds of the game in about 368 the ball will land in a red slot.

F(x)=2x is transformed to g(x)=5⋅2x. How was the graph affected?
lukranit [14]

Answer:

vertically stretched by a factor of 5

Step-by-step explanation:

Multiplying the function value by 5 makes each vertical coordinate 5 times the value it was, so it is 5 times as far away from the x-axis. This has the appearance of stretching the graph vertically by a factor of 5.

_____

Comment on the answer choices

The stretch factor is a "pure number", a ratio of new units to old units. It is "5", not "5 units."

For example, if f(x) is 1 ft (1 unit, where the unit is a foot), then g(x) = 5 ft, the value of f(x) multiplied by 5. It is not 5 ft^2, as you would get if f(x) were multiplied by 5 units, or 5 ft.
