Answer:
x= 3
Step-by-step explanation:
8x - 9 =15
+9 on both sides
8x = 15 + 9
Add 15 and 9 to get 24
8x = 14
Divide 8 by both sides
x = 3
Answer: Total Loss or Gain = $0
<u>Step-by-step explanation:</u>
Gain: $55,055 (1 + 0.16)
= $55,055 (1.16)
= $63,863.80
Profit = $8,808.80
Loss: $55,055 (1 - 0.16)
= $55,055 (0.84)
= $46,246.20
Loss = -$8,808.80
Profit + Loss
= $8,808.80 - $8,808.80
= 0
Decrease = Rs 800- Rs 640= Rs 160
Percentage decrease = (Decreased amount / Original amount) * 100
= 640/ 800 * 100 = 80%

Answer:

Step-by-step explanation:
The probability density function is :

With 0 < x < 3
To be a valid probability density function :

Where a < x < b
And also
f(x) ≥ 0 for a < x < b
Applying this to the probability density function of the exercise :





We can verify by replacing ''c'' in the original probability density function and integrating :


Also, f(x) ≥ 0 for 0 < x < 3
