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

Answer:

Step 5 is incorrect because a previous step is incorrect

Step-by-step explanation:

Step 1 correct

Step 2 correct

Step 3 correct

Step 4 incorrect: It must be

y² - 10y + 25 = 2x + 23

Step 5 incorrect because step 4 incorrect

Step 5 must be : 1/2(y - 5)² - 23/2 = x

What is 3 ln 3 - ln 9 expressed as a single natural logarithm? ln 3 ln 6 ln 18 ln 27

mariarad [96]

Answer:

$\ln(3)$

Step-by-step explanation:

The given expresion is

$3 \ln(3) - \ln(9)$

Recall that:

$n \ln(a) = \ln( {a}^{n} )$

We apply this property to get:

$\ln( {3}^{3} ) - \ln(9)$

$\ln(27) - \ln(9)$

We apply the quotient rule to get

$\ln( \frac{27}{9} )$

$= \ln(3)$

The first choice us correct
