Given the domain {-2, 1,5}, what is the range for the relation 4x +y = 3?

Simora [160]

Answer: (11, -1, -17)

Step-by-step explanation:

4x+y=3

4(-2)+y=3

-8+y=3

y=3+8

y=11

4x+y=3

4.1+y=3

4+y=3

y=3-4

y=-1

4x+y=3

4.5+y=3

20+y=3

y=3-20

y= -17

The frequency table below shows the ages of 30 children who participate in a soccer legue how many are 12 years or older

babunello [35]

First of all you need to put a table up so people know what you're talking about, but It just so happens I'm a student as well, so the answer is 5 because the question ask how many people are 12 years or older there are 3 12-14 kids and 2 15-17 kids so 3+2=5

Consider randomly selecting a student at a large university, and let A be the event that the selected student has a Visa card an

poizon [28]

Answer:

We have that $B = 0.3$ .

$0.3 = b + (A \cap B)$

However, b is a probability, which means that it cannot be negative. So no, P(A ∩ B) cannot be 0.5. It can, at most, be 0.3.

Step-by-step explanation:

Event A:

Probability that a student has a Visa card.

Event B:

Probability that the student has a MasterCard.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a student has a Visa card but not a MasterCard and $A \cap B$ is the probability that a student has both these cards.

By the same logic, we have that:

$B = b + (A \cap B)$

In this problem, we have that:

$A = 0.6, B = 0.3$

(a) Could it be the case that P(A ∩ B) = 0.5?

We have that $B = 0.3$ .

$0.3 = b + (A \cap B)$

However, b is a probability, which means that it cannot be negative. So no, P(A ∩ B) cannot be 0.5. It can, at most, be 0.3.

What is x-7=-16 and witch property of equality did you use to solve x

elena-14-01-66 [18.8K]

Answer: x = -9/ addition property of equality

Explanation: In this problem, we're given that x - 7 = -16 and we're asked to solve the equation and explain which equality we used.

The first statement we have will be

the given statement which is x - 7 = -16.

Now, we just solve the equation.

Our first and only step will be to add 7 to both sides.

Then, we find that x = -9.

The property we used here was the addition property of equality.

This property tells us that we can add the same quantity,

or equal quantities, to both sides of an equation.
