To find the percent increase, just take 96 and divide by 80. 96/80=1.2 percent as your answerr
Answer: 76.2%
Step-by-step explanation:762/1000
Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively

Step-by-step explanation:
It will take 15 years for the population to quadruple
Step-by-step explanation:
The formula for continuously compounding rate is , where
- A is the future amount
- P is the initial amount
- r is the interest as a decimal
- t is the time in years
Assume that the initial population is P
∵ The initial population = P
∵ The growth rate = 9% ⇒ compounded continuously
∴ r = = 0.09
∵ The population will quadruple in t years
∴ A = 4P
- Substitute these values in the formula
∵
∴
- Divide both sides by P
∴
- Insert ㏑ to both sides
∴ ㏑(4) = ㏑( )
∵ ㏑( ) = n
∴ ㏑ (4) = 0.09 t
- Divide both sides by 0.09
∴ t = 15.4
∴ t = 15 years to the nearest whole number
It will take 15 years for the population to quadruple
