Answer:

There's 21% of chances

Step-by-step explanation:

Here we have to use the definition of a simple probability, where all fishes has the same probability to be chose.

So, we have to divide the possible outcomes with the total of outcomes. The possible outcomes refer to the number of large-blue fishes, and the total number of outcomes represent the total number of fishes. So

P = 3/4 ≈ 0.21 (or 21%)

Therfore, there's 21% of chances to select one fish randomly and be a large, blue fish.

A recipe for crumb cake says to mix 3/8 cup of brown sugar and 1/3 cup of white sugar. From this sugar mixture, set aside 1/4 cu

ch4aika [34]

brown sugar= $\frac{3}{8}$

white sugar= $\frac{1}{3}$

you need to mix brown sugar with white sugar

$\frac{3}{8}$ + $\frac{1}{3}$ = $\frac{9+8}{24}$ = $\frac{17}{24}$

then it says you need to set aside 1/4 for the crumb topping from the previous sugar mixture that was $\frac{17}{24}$ , so

$\frac{17}{24}$ - $\frac{1}{4}$ = $\frac{68-24}{96}$ = $\frac{11}{24}$

The sugar mixture used to make the cake is $\frac{11}{24}$

Find the area of the shaded region for the given figure in terms of x.

Vlada [557]

Answer:

Area of the shaded region = (6x + 3)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the small rectangle

Area of the large rectangle = Length × Width

= (x + 2)(x + 2)

= (x + 2)²

= x² + 4x + 4

Area of the small rectangle = (x - 1)(x - 1)

= (x - 1)²

= x² - 2x + 1

Area of the shaded region = (x² + 4x + 4) - (x² - 2x + 1)

= 6x + 3

Area of the shaded region = (6x + 3)
