<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:

f(x) = 2x + 50 where f(x) is the height and x is time.

We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>

Answer: 50 meters

Step-by-step explanation: 2 is the amount of meters climbed every minute, for example 2 * 10 (x) = 20 meters in 10 minutes. So the starting point is 50 meters above sea level.

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

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
