Answer:

The answer to your question is: x = 32

Step-by-step explanation:

Data

x = ?

It is an equilateral triangle so, the three angles measure the same

2x - 4 = 5y

2x - 5y = 4

The sum of the internal angles in a triangle equals 180°

3(5y) = 180

5y = 180/3

5y = 60

y = 12

2x - 4 = 5y

2x - 4 = 5(12)

2x = 60 + 4

2x = 64

x = 64/2

x = 32

Over [174]

Answer:

a) C. No, a carton can have a puncture and a smashed corner.

b) The probability that a carton has a puncture or a smashed corner is P(X ∪ Y) = 0.104.

Step-by-step explanation:

To be mutually exclusive, the probability of the two events happening at the same time should be 0. But the probability that a carton has a puncture and has a smashed corner is 0.004 and not 0.

Then, we can conclude the events "selecting a carton with a puncture" and "selecting a carton with a smashed corner" are not mutually exclusive.

The answer is "C. No, a carton can have a puncture and a smashed corner."

We can calculate the probability that the carton has a puncture or has a smashed comer simply by adding the probability of each event:

$P(X\cup Y)=P(X)+P(Y)=0.1+0.04=0.104$

P(X ∪ Y): probability that a carton has a puncture or a smashed corner.

Identify the zeros for the function and sketch a graph. y=x(x-2)(x+3)

damaskus [11]

The product is equal to zero if one of the factors is equal to zero.

Therefore:

$y=x(x-2)(x+3)\\\\x(x-2)(x+3)=0\iff x=0\ \vee\ x-2=0\ \vee\ x+3=0\\\\\boxed{x=0\ \vee\ x=2\ \vee\ x=-3}$

F(x)=3x 3 inverse function

scoundrel [369]

Step-by-step explanation:

if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.

the inverse function simply tries to calculate the original x it of the original y.

and then, to make it a formal function, we rename x to y and y to x.

y = 3x³

x³ = y/3

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

=> as "regular" function

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