Answer:

Gabriela needs to sell 4 more cups of coffee to make a profit of $75.

She sells 90 cups and makes $0.80 profit on each cup. That equals $72 profit.

90 x $0.80= $72

She wants to make $75 profit.

$75 - $72 = $3  profit short for the day

$3/$0.80 = 3.75 cups of coffee short  so to make her profit she must sell a total of 94 cups of coffee for the day or an additional 4 cups.

About 2% of the population has a particular genetic mutation. 1000 people are randomly selected. Find the mean for the number of
Alla [95]

Answer:

Step-by-step explanation:

We khow that the genetic mutation affect 2 percent of the population .

Let's try to understand what does this mean :

  • in a group of 100 people there is possibility of finding 2 people with this genetic mutation
  • in a group of 1000 the possibility raises to 20 people so we can deduce that each time we add a zero we add a zero in 2

so :

  • 100⇒2
  • 1000⇒20
  • 10000⇒200
  • 100000⇒2000

and so on

Find the inverse function of
shtirl [24]

Answer:

f(x) = 20x - 4 \\ substitute \: y \: for \: f(x) \\ y = 20x - 4 \\ interchange \: x \: and \: y \\ x = 20y - 4 \\ swap \: the \: sides \: of \: the \: equation \\ 20y - 4 = x \\ move \: the \: constant \: to \: the \: right \: hand \\ 20y = x + 4  \\ divide \: both \: sides \: by \: 20 \\ y =  \frac{1}{20} x +  \frac{1}{5}  \\ substitute \: f {}^{ - 1} (x) \: for \: y \\ f {}^{ - 1} (x) =  \frac{1}{20} x +  \frac{1}{5}

The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.

Thus, domain of f(x): x∈R = range of f¯¹(x)

and range of f(x): x∈R =domain of f¯¹(x)
