Which statements best describe displacement? Check all that apply.Displacement is measured along the path an object travels.
Displacement is a measurement that includes direction.
Displacement is the difference between a starting point and an ending point.
Displacement is how far an object travels from starting point to ending point.
Displacement is measured as a straight line between a starting point and an ending point.

Answers

Answer: displacement is a measure that includes direction

Displacement is the difference between a starting point and a ending point

Displacement is measured as a straight line between a starting point and an ending point

Step-by-step explanation:

I think it’s how far an object travels from starting point to ending point.

What are the solutions to the quadratic equation 4x^2 = 64? A. x = −16 and x = 16
B. x = −8 and x = 8
C. x = −4 and x = 4
D. x = −2 and x = 2

Answers

Answer:

C

Step-by-step explanation:

Given

4x² = 64 ( divide both sides by 4 )

x² = 16 ( take the square root of both sides )

x = ± √(16) = ± 4

Solutions are x = - 4 and x = 4 → C

What is the range of the following data values? 47, 28, 92, 34, 83

Answers

First, put all of the numbers in a list ranking from high to low (or low to high) and subtract the highest and lowest values.

92 - 28 = 64
The range is 64

Hope this helps!!

The probability that Emma has heart disease is 0.6. She decides to take a test for the disease that is 80% accurate. What is the probability that Emma has heart disease and the test predicts heart disease?

Answers

Answer:

The probability that Emma has heart disease and the test predicts heart disease is:

                                48%

Step-by-step explanation:

Let A denote the event that Emma has a heart disease.

and B denote the event that the test predicts accurate.

Hence, A∩B denote the event that Emma has heart disease and the test predicts heart disease.

From the given equation we have:

             P(A)=0.6

and P(B)=80%=0.8

As we know that event A and event B are independent.

Hence, we have:

P(A∩B)=P(A)×P(B)

⇒  P(A∩B)=0.6×0.8

⇒  P(A∩B)=0.48=48%

                Hence, the probability is:

                           48%

0.6 x 0.8 = 12/25 The probability that Emma has heart disease and the test predicts it is 48%

In the circle, measure of Arc BC = 62°. The diagram isn't drawn to scale. what is the measure of Arc BCP?

Answers

Answer:

Option D. ∠BCP = 31°

Step-by-step explanation:

As we know by the theorem tangent and chords, an angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.

Theorem clearly reveals ∠BCP = (mBP)/(2)

Since arc BC = 62°

So ∠BCP = (62)/(2)=31

Option D. ∠ BCP = 31° is the answer.

PQ is the tangent, therefore you can use a theorem: The arc measure is double the amount of the angle the tangent makes.

So: 62/2=31
