It's 4.35 • 10^-4 becuase you move the decimal place to the left four places
Answer:
The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
Distributed uniformly between 3mm and 13 mm.
This means that 
Calculate the proportion of memory sticks that will be scrapped:

The proportion of memory sticks that will be scrapped is 0.3 = 30%.
Answer:
Explained below.
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Here,
Then,
Angle P + Angle Q = 90°
2x + 7x = 90°
9x = 90°
x = 90/9
x = 10°
Therefore,
- Measurement of Angle P = 2x = 2*10 = 20°
- Measurement of Angle Q = 7x = 7*10 = 70°
