Answer:

35 + .80x > 50

Step-by-step explanation:

You have the original price, which is 35 dollars. Then you have per page, it's 80 cents. You don't know how many pages there are, so you put x. Then it has to be LESS than 50, so you put > 50

In a survey of a community, it was found that 85% of the people like winter season and 65% like summer season. If none of them d

KengaRu [80]

Answer:

50%

Step-by-step explanation:

Let :

Winter = W

Summer = S

P(W) = 0.85

P(S) = 0.65

Recall:

P(W u S) = p(W) + p(S) - p(W n S)

Since, none of them did not like both seasons, P(W u S) = 1

Hence,

1 = 0.85 + 0.65 - p(both)

p(both) = 0.85 + 0.65 - 1

p(both) = 1.50 - 1

p(both) = 0.5

Hence percentage who like both = 0.5 * 100% = 50%

The probability that an international flight leaving the United States is delayed in departing (event D) is .29. The probability

Blizzard [7]

Answer:

$P(D|P)= \frac{0.11}{0.59}=0.186$

Step-by-step explanation:

For this case we have defined the following events:

D= "An international flight leaving the United States is delayed in departing"

P="An international flight leaving the United States is a transpacific flight "

And we have defined the probabilities:

$P(D)= 0.29 , P(P) = 0.59$

And for the event: "an international flight leaving the U.S. is a transpacific flight and is delayed in departing" $D \cap P$ we know the probability:

$P(D \cap P) =0.11$

We want to find this probability:

What is the probability that an international flight leaving the United States is delayed in departing given that the flight is a transpacific flight

So we want this probability:

$P(D|P)$

And we can use the conditional formula from the Bayes theorem given two events A and B:

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

And if we use this formula for our case we have:

$P(D|P)= \frac{P(D \cap P)}{P(P)}$

And if we replace the values we got:

$P(D|P)= \frac{0.11}{0.59}=0.186$

What are the coordinates of the vertices of the triangle under the translation (x, y) —> (x + 2, y + 3)?

tamaranim1 [39]

For each vertex just take the x and y coordinate and apply the translation. so for the point (-3,-2) make them (-3+2, -2+3)=(-1,1) and do the same for the other two points (0,2) and (-7,3)
