7. A machine produces memory sticks of varying lengths, distributed uniformly between 3mm and 13 mm. Memory sticks longer than 1

Mars2501 [29]

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:

$P(X < x) = \frac{x - a}{b - a}$

The probability of finding a value between c and d is:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

The probability of finding a value above x is:

$P(X > x) = \frac{b - x}{b - a}$

Distributed uniformly between 3mm and 13 mm.

This means that $a = 3, b = 13$

Calculate the proportion of memory sticks that will be scrapped:

$P(X > 10) = \frac{13 - 10}{13 - 3} = \frac{3}{10} = 0.3$

The proportion of memory sticks that will be scrapped is 0.3 = 30%.

Formulas and Literal Equations

miskamm [114]

Answer:

$x = 23$

Step-by-step explanation:

Given, $\frac{x - 5}{2} = 9$ , solve for x.

Multiply both sides by 2

$\frac{x - 5}{2} \times 2 = 9 \times 2$

$x - 5 = 18$

Add x to both sides

$x - 5 + 5 = 18 + 5$

$x = 23$
