Answer:
<u>Mode = 1</u>
Step-by-step explanation:
<u>Relation between the Central Measures of Tendency</u>
- Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
- The formula between the three is given by :
- ⇒ <u>Mode = 3Median - 2Mean</u> or <u>Mode + 2Mean = 3Median</u>
<u></u>
<u>Solving</u>
- Median = 5
- Mean = 7
Therefore,
- Mode = 3(5) - 2(7)
- Mode = 15 - 14
- <u>Mode = 1</u>
Answer:

Step-by-step explanation:
The equation for photon energy is given by:

Where:

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.
So, replacing the data provided in the previous equation:

Answer:
<h3>x = -3</h3>
Step-by-step explanation:
First let us get the equation of the coordinates
y-y0 = m(x-x0)
Using the coordinates ( - 3, 2 ), ( - 1, 0 )
m = 0-2/-1-(-3)
m = -2/2
m = -1
Substitute m = -1 and (-1, 0) into the formula
y - 0 = -1(x+1)
y = -x-1
f(x) = -x-1
Since f(x) = 2
2 = -x-1
-x = 2+1
-x = 3
x = -3
Hence the value of x is -3
Answer:
The equation that represents the graph is y = 40x
The new equation would be y = 45x
Step-by-step explanation:
As y increases by 40, x increases by 1, so 40/1, or 40
New equation: $90 per 2 months, y = 90, x = 2, 90/2 = 45
