A tire manufacturer knows that 5% of tires contain a defect, and the presence of a defect is independent from tire to tire.

saul85 [17]

The probability that if 5 tires are inspected, exactly 2 have a defect is 0.021

<h3>How to calculate the probability</h3>

The given parameters are:

$p = 5\%$ --- the proportion that contains defect

$n =5$ --- the sample size

$r =2$ -- the selected sample

The probability is then calculated as:

$P(x =r) = ^nC_r * p^r * (1 - p)^{n-r}$

So, we have:

$P(x =2) = ^5C_2 * (5\%)^2 * (1 - 5\%)^{5-2}$

$P(x =2) = 10 * (5\%)^2 * (1 - 5\%)^3$

$P(x =2) = 0.021$

Hence, the probability that if 5 tires are inspected, exactly 2 have a defect is 0.021

What is the simplified form of x plus 4 over x squared minus 3x minus 10⋅x minus 3 over x squared plus x minus 12? (6 points)

melomori [17]

Answer:

The simplified form is 1 over the quantity x plus 2 times the quantity

x minus 5 ⇒ 1/(x+2)(x-5) ⇒ last answer

Step-by-step explanation:

* Lets write the product of the two fraction

∵ $\frac{x+4}{x^{2}-3x-10} *\frac{x-3}{x^{2}+x-12}$

- At first factorize the denominators

# x² - 3x - 10

∵ x² = x × x ⇒ 1st term in the 1st bracket and 1st term in the

2nd bracket

∵ -10 = 2 × -5 ⇒ 2nd term in the 1st bracket and 2nd term in the

2nd bracket

∵ x × - 5 = -5x ⇒ ext-reams

∵ x × 2 = 2x ⇒ means

∵ 2x + -5x = -3x ⇒ middle term

∴ x² - 3x - 10 = (x + 2)(x - 5)

# x² + x - 12

∵ x² = x × x ⇒ 1st term in the 1st bracket and 1st term in the

2nd bracket

∵ -12 = -3 × 4 ⇒ 2nd term in the 1st bracket and 2nd term in the

2nd bracket

∵ x × 4 = 4x ⇒ ext-reams

∵ x × -3 = -3x ⇒ means

∵ 4x + -3x = x ⇒ middle term

∴ x² + x - 12 = (x - 3)(x + 4)

* Lets write the fractions after factorization

∴ $\frac{x+4}{(x+2)(x-5)}*\frac{x-3}{(x-3)(x+4)}$

- lets simplify the fractions by cancel (x - 3) up with (x - 3) down

and cancel(x + 4) up with (x + 4) down

∴ $\frac{1}{(x+2)(x-5)}*1=\frac{1}{(x+2)(x-5)}$

* The simplified form is 1 over the quantity x plus 2 times the

quantity x minus 5
