Answer:

Yes, because when waves are at the same place at the same time, the amplitudes of the waves simply add together and this is really all we need to know!

Step-by-step explanation:

The sum of two waves can be less than either wave, alone, and can even be zero. This is called destructive interference.

If we place the waves side-by-side, point them in the same direction and play the same frequency, we will have constructive interference.

Answer:

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

Step-by-step explanation:

Probability of a defective part:

0.04 of $\frac{100}{180}$ , that is, coming from A.

0.05 of $\frac{80}{180}$ , that is, coming from B. So

$p = 0.04\frac{100}{180} + 0.05\frac{80}{180} = \frac{0.04*100 + 0.05*80}{180} = 0.0444$

0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.

Using the number line as a guide, work out the difference between the numbers given.

inn [45]

Answer:

If these are addition:

1) 7

2) 3

3) 1

4) -3

5) 0

6) -5

If they are subtraction:

1) 9

2) 9

3) -7

4) 7

5) -4

6) 3

Step-by-step explanation:

Difference is subtraction, but your examples (7 and -3 = 10) implies that these are addition problems. Next time please set them up in a mathematical form.

This is how the problems would be set up:

Addition:

1) 8+(-1)= 7

2)6+(-3)= 3

3)-3+4= 1

4)2+(-5)= -3

4)-2+(-2)= 0

6)-1+(-4)= -5

Subtraction:

1) 8-(-1)= 9

2)6-(-3)= 9

3)-3-4=- 7

4)2-(-5)= 7

4)-2-(-2)= -4

6)-1-(-4)= 3
