The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%. The probability that a toy Raymond pi

GalinKa [24]

Answer:

0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.

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: Dinosaur

Event B: Plush.

The probability that a toy Raymond picks out of a box is a dinosaur is 75%.

This means that $P(A) = 0.75$

The probability that a toy Raymond picks out of a box is both plush and a dinosaur is 30%.

This means that $P(A \cap B) = 0.3$

What is the probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.3}{0.75} = 0.4$

0.4 = 40% probability that a toy that Raymond picks out of a box is plush given that it is a dinosaur.

Triangle ABC is a right triangle. The legs of the triangle are AB = 6 cm and BC = 12 cm. Find the measure of angle A.

Mnenie [13.5K]

Answer:

63.4°

Step-by-step explanation:

Given that AB and BC are the legs of the right triangle, then opposite to angle A is side BC and adjacent to angle A is side AB.

By definition, the tangent of angle A is:

tan(∠A) = opposite leg / adjacent leg

tan(∠A) = BC/AB

tan(∠A) = 12/6

∠A = arctan(2)

∠A = 63.4°

Help ASAP i need the answer to this question plsss NO LINKS AND NO DOING IT JUST FOR THE POINTS Will give brainliest and just be

siniylev [52]

Answer:

reflect across x axis: (x,-y)

reflect across y axis: (-x,y)

reflect across y=x: (y,x)

reflect across y= -x: (-y,-x)

90 cc rotation: (-y,x)

180 rotation: (-x,-y)

270 cc rotation: (y,-x)

Step-by-step explanation:

reflect across x axis: (x,-y) - x coor stays same and only y coor becomes negative

reflect across y axis: (-x,y) - x coor becomes negative and y coor stays the same

reflect across y=x: (y,x) - both coordinate switch places, no signs are changed

reflect across y= -x: (-y,-x) - both coordinates switch places and the signs are switched to the opposite sign of the original number

90 cc rotation: (-y,x) - opposite of the original y coor and both coordinates switch place (same as 270 clockwise)

180 rotation: (-x,-y) - both coordinates stay in there original place but with the opposite values of the original value

270 cc rotation: (y,-x) - both coordinates switch places and the x values is the opposite of the original value (same as 90 clockwise)

*to find the third columns answer all you have to do is plug in the given x and y values into the coordinate rule
