A bicycle manufacturer is studying the reliability of one of its models. The study finds that the probability of a brake defect

dangina [55]

Answer:

The probability of a chain defect is 3%.

Step-by-step explanation:

Given : A bicycle manufacturer is studying the reliability of one of its models. The study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent.

If the probability of a defect with the brakes or the chain is 6 percent

To find : What is the probability of a chain defect?

Solution :

Let A be the event of brake defect

and B be the event of chain defect.

We have given, P(A)= 4%=0.04

P(A and B) = 1%=0.01

P(A or B)= 6%=0.06

We have to find P(B),

The formula used is,

$P(A \text{ or } B) = P(A) + P(B) - P(A \text{ and } B)$

Substitute the value,

$0.06= 0.04+ P(B) - 0.01$

$0.06= 0.03+ P(B)$

$0.06-0.03=P(B)$

$P(B)=0.03$

or $P(B)=3\%$

Therefore, The probability of a chain defect is 3%.

Country A has a growth rate of 2.2% per year. The population is currently 5,667,000, and the land area of Country A is 31,000,00

Akimi4 [234]

Answer:

It will be 290 years until there be one person for every square yard of land.

Step-by-step explanation:

We are looking for when the country's population is equivalent to its area in square yards: 31,000,000,000.

Write an equation for the situation: (Trickiest part)

p(x) = (5,667,000)(1 + 0.022)ˣ <= Can modify compound interest equation

31,000,000,000 = (5,667,000)(1 .022ˣ)

Started rounding off numbers

547.056 = 1 .022ˣ <= $x = \frac{log(ans)}{log(base)}$

Solve using log.

x = 2.738 / 0.00945 <= log(547.056) / log(1.022)

x = 289.7 <= Round up because rate is annual. Before the 290th year, the population is less than the number of square yards.

x = 290

Total amount with annual compound interest equation applied to this problem:

$A = P(1 + r)^{t}$ (Principle is starting investment)

Population = (Starting population)(1 + growth rate)^(time)
