Solve for y. 3.2 = 2y. please answer thanks :)

PilotLPTM [1.2K]

Answer:

Simplifying

3.2 = 2y

Solving

3.2 = 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3.2 + -2y = 2y + -2y

Combine like terms: 2y + -2y = 0

3.2 + -2y = 0

Add '-3.2' to each side of the equation.

3.2 + -3.2 + -2y = 0 + -3.2

Combine like terms: 3.2 + -3.2 = 0.0

0.0 + -2y = 0 + -3.2

-2y = 0 + -3.2

Combine like terms: 0 + -3.2 = -3.2

-2y = -3.2

Divide each side by '-2'.

y = 1.6

Simplifying

y = 1.6

35% of students take spainsh or engineering. 30% of students take Spanish. 25% of students take engineering. What is the probabi

vladimir2022 [97]

Answer:

0.2 = 20% probability that a student takes Spanish and engineering

Step-by-step explanation:

We solve this question treating the probabilities as Venn sets.

I am going to say that:

Event A: Student takes Spanish

Event B: Student takes Engineering.

35% of students take spainsh or engineering.

This means that $P(A \cup B) = 0.35$

30% of students take Spanish.

This means that $P(A) = 0.3$

25% of students take engineering.

This means that $P(B) = 0.25$

What is the probability that a student takes Spanish and engineering?

This is $P(A \cap B)$ .

These probabilities are related by the following formula:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

Replacing the values

$P(A \cap B) = 0.3 + 0.25 - 0.35 = 0.2$

0.2 = 20% probability that a student takes Spanish and engineering
