A basket contains four apples and six peaches. You randomly select one piece of fruit and eat it. Then you randomly select anoth

Sveta_85 [38]

Answer:

Answer as a fraction: 4/15

Answer as a decimal: 0.267

The decimal version is approximate rounded to three decimal places.

Step-by-step explanation:

6 apples, 4 peaches

6+4 = 10 pieces of fruit total

The probability of picking an apple is 6/10 = 3/5

After you pick and eat the apple, there are 10-1 = 9 pieces of fruit left. Also, the probability of picking a peach is 4/9, as there are 4 peaches out of 9 fruit left over.

Multiply out 3/5 and 4/9 to get (3/5)*(4/9) = (3*4)/(5*9) = 12/45 = 4/15

Using a calculator, 4/15 = 0.267 approximately.

What is the inverse of the function

Evgesh-ka [11]

Answer:

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = $\frac{19}{x^3}$ ( multiply both sides by x³ )

x³y = 19 ( divide both sides by y )

x³ = $\frac{19}{y}$ ( take the cube root of both sides )

x = $\sqrt[3]{\frac{19}{y} }$

Change y back into terms of x, then

$f^{-1}$ (x) = $\sqrt[3]{\frac{19}{x} }$ = $\frac{\sqrt[3]{19} }{\sqrt[3]{x} }$ → A

Considere um triângulo retângulo, cujos ângulos agudos a e b satisfazem à condição cos a = 0,8 e cos b = 0,6 Determine a área de

Anni [7]

Answer:

7.5 cm^2

Step-by-step explanation:

Aqui, temos Cos A = 0,8 = 8/10 = 4/5.

Cos B = 0,6 = 6/10 = 3/5.

O que isto significa é que os dois outros lados do triângulo retângulo são 3 cm e 5 cm, respectivamente.

Isso ocorre porque, o oposto do ângulo agudo A é adjacente ao ângulo agudo B e vice-versa.

Portanto, a partir dos valores de ambos, podemos obter os dois outros lados.

Matematicamente, a área da direita é 1/2 * b * h b e h são 3 e 5, respectivamente.

Assim, área = 1/2 * 3 * 5 = 7,5 cm ^ 2

Hannah and Anthony are siblings Who have ages that are consecutive odd numbers do some of their ages is 92 which equations could

baherus [9]

Let Hannah's age be represented by h;

Since Anthony's age is a consecutive odd number age; his age is (h+2)

92=(h)(h+2)
92-2=2h
90=2h
90/2=h
45=h

If Hannah is 45 years old, Anthony is (45+2)= 47 years old

Hope I helped :)
