If the incident light changes from a wavelength of 630 nm to 420 nm, the fringe spacing will decrease, resulting in fringes that are closer together.

In a double-slit experiment, when light passes through two narrow slits and hits a viewing screen, interference patterns are observed. The fringe spacing, also known as the separation between adjacent bright fringes, is determined by the wavelength of the incident light. The formula for calculating fringe spacing is given by:

Fringe Spacing = (wavelength * distance from slits to screen) / distance between the slits

Given that the fringe spacing is initially 1.8 mm when the incident light has a wavelength of 630 nm, we can use the formula to calculate the new fringe spacing when the light wavelength changes to 420 nm. Since the distance from the slits to the screen and the distance between the slits remain constant, the only variable that changes is the wavelength. As the wavelength decreases, the fringe spacing will also decrease. Therefore, the fringe spacing will be smaller when the light wavelength is 420 nm compared to when it is 630 nm.

Triangles are congruent by SAS postulate.

Answer:

6.104

Step-by-step explanation:

Given that,

Mean, {eq}\mu = 6.8 {/eq}

Standard deviation, {eq}\sigma = 0.37 {/eq}

{eq}P(X < x) = 0.03\\ P(\dfrac{X - \mu}{\sigma} < \dfrac{x - \mu}{\sigma}) = 0.03\\ P(Z < \dfrac{x - 6.8}{0.37}) = 0.03\\ P(Z < z) = 0.03 {/eq}

Excel function for the value of z:

=NORMSINV(0.03)

{eq}z = -1.881\\ \dfrac{x - 6.8}{0.37} = -1.881\\ x = 6.8-1.881\times 0.37\\ \color{blue}{x = 6.104 \ minutes} {/eq}

To be sponsored by the running shoe company as one of the fastest 3% of runners, one would need to run faster than the upper 3rd percentile of runners. This can be calculated using the z-score formula which is given as; z = (x - μ) / σ where x is the value we want to find the percentile of, μ is the mean and σ is the standard deviation.

The z-score formula can be rearranged to solve for x which is the running time needed to be sponsored by the company as follows;x = z * σ + μWe want to find the upper 3rd percentile, which corresponds to a z-score of 1.88 (from z-tables or calculator).

Therefore;1.88 = (x - 7.2) / 0.56. Rearranging to solve for x;x = 1.88 * 0.56 + 7.2x = 8.1888 (rounded to 4 decimal places)Therefore, one would need to run faster than 8.1888 minutes to be sponsored by the running shoe company as one of the fastest 3% of runners.

Step-by-step explanation:

Graph J

Step-by-step explanation:

The graph of f(x) = x² is transformed to create the graph of h(x) = 2f(x) = 2x²

Now, for x = 0, f(x) = 0 and h(x) = 0

Therefore, both the graphs passes trough the origin.

Now, for x = 1, f(x) = 1 and h(x) = 2

Therefore, f(1) < h(1)

Hence, the graph J represents the correct graph of f(x) and h(x).

Step-by-step explanation:

If a sample of 8 scores has a mean of 10 and after removing one score, the mean of the remaining scores is 11, the score that was removed is 7.

The mean of the original sample is 10. This means that the sum of the scores in the sample is 8 multiplied by 10, which equals 80. After one score is removed, the mean of the remaining scores is 11. Since there are now 7 scores remaining in the sample, the sum of those scores is 7 multiplied by 11, which equals 77.

To find the score that was removed, we need to calculate the difference between the sum of the original sample and the sum of the remaining scores. The difference is 80 minus 77, which equals 3. Therefore, the score that was removed from the sample is 3.

To find the perimeter of a square, we need to know the length of one side. Since the area of the square is given as 200 square feet, we can find the length of one side by taking the square root of the area.

Let's calculate:

√(200) ≈ 14.14 ft

The length of one side is approximately 14.14 feet. Since a square has four equal sides, the perimeter is calculated by multiplying the length of one side by 4:

Perimeter = 4 * 14.14 ft = 56.56 ft

Therefore, the correct answer is approximately 56.56 ft.

Synthetic division

Answer:

3 mph

Step-by-step explanation:

UPSTREAM:

distance = 36 miles ;

Speed = 15-c mph ;

TIME, t = distance / speed = 36/(15-c)

Downstream :

distance = 36 miles ;

speed = 15+c mph ;

time, t = 36/(15+c)

upstream time + downstream time = 5 hrs

36/(15-c) + 36/(15+c) = 5

36(15+c) + 36(15-c) = 5(15-c)(15+c)

1080 = 5(225 - c²)

1080 / 5 = 225 - c²

216 = 225 - c^2

216 - 225 = c²

-9 = c²

c = 3

The actual percent of residents who will eat at the restaurant is expected to be closest to 56%.

The sample sizes for the four surveys are 10, 20, 280, and 200. The number of "yes" responses for each survey are 3, 9, 50, and 132, respectively. The percent of responses for each survey are 30%, 45%, 56%, and 66%, respectively.

The average percent of responses for the four surveys is 53%. However, the survey with the largest sample size has a percent of responses of 56%. This suggests that the actual percent of residents who will eat at the restaurant is closer to 56% than 53%.

It is important to note that the actual percent of residents who will eat at the restaurant may be higher or lower than 56%. This is because the surveys are only a sample of the population, and the results may not be representative of the entire population.

The value of the middle of the three is 25.

Let x be the first odd integer, then the next two consecutive odd integers are x+2 and x+4. The sum of these three consecutive odd integers is given as 75, so we can write the equation:

x + (x+2) + (x+4) = 75

Simplifying the left side of this equation gives:

3x + 6 = 75

Subtracting 6 from both sides gives:

3x = 69

Dividing by 3 gives:

x = 23

So the first odd integer is 23, and the next two consecutive odd integers are 25 and 27. The middle of these three is the second consecutive odd integer, which is 25. Therefore, the value of the middle of the three is 25.

Answer:

The answer is 35 miles.

Step-by-step explanation:

Let's assume that the distance from W to Y is x miles

Distance from W to X is 70 % of x =0.7*x

Given distance from X to Y is 15 miles.

x-15=0.7x

x-0.7x=15

0.3x=15

x=15/0.3

x=50miles

Thus the distance from W to Y is 50 miles and the distance from W to X is 50-15=35 miles
