Step-by-step explanation:

use the law of cosine for right triangles cos(θ)= adjacent/ hypotenuse

cos(θ)=31/47=.659

θ=inverse cosine of .659

θ=48.73

A box contains 20 miniature golf putt-putt balls; 10 are

stellarik [79]

Answer: The answer is provided below

Step-by-step explanation:

From the question, a box contains 20 miniature golf putt-putt balls out of which 10 are yellow, 6 are red, and the remaining 4 are pink.

The probability of picking a red golf ball will be:

= 6/20 × 100

= 600/20

= 30%

If the red ball is replaced, the probability of picking a yellow golf ball will be:

= 10/20 × 100%

= 50%

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.

-6 (p + 8) = -35 + 7p

Novosadov [1.4K]

Answer:

p = −1

Step-by-step explanation:

1. Regroup terms.

−6 (p + 8) = 7p − 35

2. Expand.

−6p − 48 = 7p − 35

3. Add 6p to both sides.

−48 = 7p − 35 + 6p

4. Simplify 7p − 35 + 6p to 13p −35.

−48 = 13p − 35

5. Add 35 to both sides.

−48 + 35 = 13p

6. Simplify −48 + 35 to −13.

−13 = 13p

7. Divide both sides by 13.

−1 = p

8. Switch sides.

p = −1
