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.

The points (-16,r) and (-4,11)lie on a line with slope 1/2. Find the missing coordinate r?

Sergio [31]

Answer: The missing coordinate R is 5.

Step-by-step explanation:

11=1/2(-4) + B

11=-2 +B

B= 13

B represents the y-intercept

so we will use the equation y=mx + B and we know the slope and y intercept.

r= 1/2(-16) + 13

r= 5

A 4-bedroom, 4-bath 4,875 square feet house was listed at $445,000. Andreas, the seller, accepted an offer that was 95% of the l

klasskru [66]

Answer: He gets $86.71 per square foot

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>Area = 4,875 square feet </em>

<em>Price = $445,000 </em>

First, we have to divide the price of the house by the area, to obtain the price per square foot:

Mathematically speaking:

$445,000 / 4,875 square feet = $91.2 per square foot (original price)

Now we have to multiply it by the offer in decimal form (95/100 =0.95)

$91.2 x 0.95 = 86.71 per square foot

He gets $86.71 per square foot.
