Answer:

y= -2x+3

Step-by-step explanation:

Point slope form= y=mx+b

The m is the slope.

So, we have an incomplete equation right now: y= -2x+b

We want to find b. We can do that by plugging in values for the x and y coordinates. Fortunately, we do have a set of coordinates, (1, 1)!

We plug them in:

1= -2(1)+b

1= -2+b

b=3

So, since we have the slope and the b, also called the y-intercept, we can form an equation!

y= -2x+3

Solve the inequality for x:

5x - 3 ≤ 7x +7

Subtract 7x from each side:

-2x -3 ≤ 7

Add 3 to each side:

-2x ≤ 10

Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:

x ≥ -5

The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.

The correct answer is D.

Well two pints equal one quart

If Damian needed 3 pints
but buys in 3 quarts
then he would have to buy 3 quarts

Which 3 quarts is equivalent to 6 pints.

Write the symbols for the probability that of all the outfielders, a player is not a great hitter.

Mumz [18]

The symbolic representation of the conditional probability

$P(G'|O) = \frac{P(G'nO)}{P(O)}$

This is a conditional probability problem ; which can be expressed explicitly as ;

The probability of not being a great hitter Given that the player is an outfielder
Recall :

Probability of A given B is defined as ;

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

Let :

Probability that a player is an outfielders = P(O)

Probability that a player is a Great hitter = P(G)

Probability that a player is not a great hitter = P(G')

Probability that a player is not a great hitter given that he is an outfielder = P(OnG')

Therefore, we have :

$P(G'|O) = \frac{P(G'nO)}{P(O)}$
