The slope of the line is..?<br> A. -2<br> B. -1<br> C. 1<br> D. 2

Nezavi [6.7K]

Answer:

B, -1

Step-by-step explanation:

on a graph with 2 points (or more) listed, you can count the points from each coordinate to determine slope (which is rise/run also known as y/x)

going from left to right, we start at (1,4) and count down from (1,4) to (3,2), we go down 2 units

going from left toright again, we start from (1,2) (our point we counted down to from (1,4) and count to the left 2 units

we are now at (3,2)

it took us 2 points down (negative) and 2 to the right (positive) to get from (1,4) to (3,2)

using rise/run we have the following:

-2/2 < we can simplify this further by dividing -2 by 2 and getting 1

the answer is B, -1

ANOTHER WAY

another way we can calculate the slope is by the following formula

y2 - y1/ x2- x1

(1,4) is our x1 and y1, while (3,2) is our x2, y2. we plug this into the formula and we get:

y2 - y1 = 2 - 4 = -2

x2 - x1 = 3 - 1 = 2

-2 / 2 = -1

we still have the same answer, and this formula is useful when you dont have a graph to count down from

In Littletown, the probability that a baseball team goes to the city playoffs is

tatuchka [14]

Answer:

C. 0.10

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Goes to the city playoffs

Event B: Goes to the state playoffs.

In Littletown, the probability that a baseball team goes to the city playoffs is 0.20.

This means that $P(A) = 0.2$

The probability that the team goes to the state playoffs given that the team goes to the city playoffs is 0.50.

This means that $P(B|A) = 0.5$

What is the probability that a randomly selected team from Littletown goes to the city and state playoffs?

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

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(A \cap B) = P(A)*P(B|A) = 0.2*0.5 = 0.1$

The correct answer is given by option C.
