It is helpful to put the 14 data values in order:

... 65, 72, 74, 75, 75, 75, 86, 89, 93, 95, 95, 96, 97, 100

Because there are an even number of data values, the median is the average of the middle two values. Those are 86 and 89, so the median is (86+89)/2 = 87.5

This in-order sequence of values also helps us identify any repeated values. All values are present only once, except 75, which is present 3 times. The value present the largest number of times is the mode. The mode is 75.

At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?

hichkok12 [17]

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

$d*sin(\theta) = m\lambda$

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle

At the first-order maximum (m=1) at 20.0 degrees we have:

$\frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342$

Now, to produce a second-order maximum (m=2) the angle must be:

$sin(\theta) = \frac{\lambda}{d}*m$

$\theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ}$

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.

I hope it helps you!

Which combination of three side lengths will NOT form a triangle?

SpyIntel [72]

Answer:

The combination 9 mm, 6mm, 5mm will not form a triangle.

9 +6 = 15 > 5

6+5= 11 < 9

9+5 =14 > 6

Explanation :

because the side length of triangle does not obey triangle inequality theorem.

The triangle inequality theorem:

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Answer:

125 defective jeans

Step-by-step explanation:

We are told that;

During inspections, 5 defective pairs of jeans are found in a shipment of 200 pairs of jeans .

We are supposed to determine the number of defective jeans in a shipment of 5000 pairs, if the trend continues.

Therefore;

5 defective = 200 pairs

What about in 5000 pairs?

Number of defective pairs = (5000 × 5 ) ÷ 200

= 125 defective pairs

Thus, in a shipment of 5000 pairs of jeans there will be 125 defective pairs

I’ll mark brainliest!!!

ludmilkaskok [199]

Answer: odd

Step-by-step explanation:

Given

The graph of a function increases as x increases and decreases as x decreases.

This shows that the degree of the polynomial is odd

for example $y=x^3$

Here, the leading coefficient is positive, and the value of function increases as x increases and vice-versa.
