Area of a rectangle = length * width.

hence, l = 11 and w = 4

The quality control team of a company checked 800 digital cameras for defects. The team found that 20 cameras had lens defects,

dmitriy555 [2]

Answer:

0.025

Step-by-step explanation:

-This is a conditional probability problem.

-Let L denote lens defect and C charging defect.

#We first calculate the probability of a camera having a lens defect;

$P(lens)=\frac{Lens}{Total}\\\\=\frac{20}{800}\\\\=0.025$

#Calculate the probability of a camera having a charging defect:

$P(Charging)=\frac{Charging}{Total}\\\\=\frac{25}{800}\\\\=0.03125$

The the probability that a camera has a lens defect given that it has a charging defect is calculated as:

$P(L|C)=\frac{P(C)P(L)}{P(C)}\\\\=\frac{0.025\times 0.03125}{0.03125}\\\\=0.025$

Hence, the probability that a camera has a lens defect given that it has a charging defect is 0.025

Answer:

Question 3: $b \geq 2$

Question 4: $r < -5$

Question 5: $y \leq -6$

Step-by-step explanation:

Question 3:

$b + 2 \geq 4\\b + 2 -2 \geq 4 - 2\\b \geq 2\\$

Question 4:

$13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5$ sign flips when r switches sides

Question 5:

$3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\$
