A city's population has increased 40% in the last 5 years and is now 53,782 people.
What was the population 5 years ago?
Given:
A city's population has increased 40% in the last 5 years and is now 53,782 people.
To find:
The population 5 years ago.
Solution:
Let x be the population 5 years ago.
A city's population has increased 40% in the last 5 years.
So, present population is
[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]
It is given that the present population is 53782.
[tex]1.4x=53782[/tex]
[tex]x=\dfrac{53782}{1.4}[/tex]
[tex]x=38415.7142857[/tex]
[tex]x\approx 38416[/tex]
Therefore, the population 5 years ago was about 38416.

Answer:
Step-by-step explanation:
(8b+12)+(3n+6)+(9b-4)
Remove the parentheses:
8b+12+3n+6+9b-4
Group like terms:
8b+9b+3n+12+6-4

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6 days after inoculation?
y = 1,000(1.15)6; 2,313 bacteria
y = 1,000(1.15)7; 2,660 bacteria
y = 1,000(1.5)5; 7,594 bacteria
y = 1,000(1.5)6; 11,391 bacteria
Answer:
A
Step-by-step explanation:
The population of the culture 6 days after inoculation is 2,313.
Correct option is (A).
What is Compounding?When interest is earned and then reinvested, the total interest on the principle is calculated using compounding. It causes assets or capital to increase exponentially for investors.
As per the given data:
Number of bacteria initially (P) = 1000
Growth rate of the bacteria = 15% each day
Growth rate of the bacteria in decimal (r) = 0.15
Number of days (n) = 6
The bacteria is growing each day with 15% each day, hence it is compounding.
The population of the culture 6 days after inoculation (y):
[tex]y = P (1+r)^t[/tex]
[tex]y = 1000 (1+0.15)^6[/tex]
[tex]y = 1000 (1.15)^6[/tex]
y = 2,313
Hence, The population of the culture 6 days after inoculation is 2,313.

The slope of the linear model is 1.5. What does this
mean in terms of the maximum noise level and the
number of people?
Answer:
Noise level increase by 1.5 per unit increase in number of persons
Step-by-step explanation:
The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.
The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.
Shoes and hats are on sale. The expression 1/4(s + 24.80) can be used to determine the discount when you buy shoes with a retail price of s dollars and hats with a total retail price of $24.80. Write another expression that can be used to determine the discount.
Answer:
0.25s + 6.2
Step-by-step explanation:
Discount on sale expression : 1/4(s + 24.80)
Retail price of shoe = s
Retail price of hats = 24.80
From expression, we can conclude that there is a ; 1/4 = 0.25 = (0.25 * 100%) = 25% discount on each item ;
Hence, discount expression could be written as :
0.25s + 0.25(24.80)
0.25s + 6.2

If the probability that a person will die in the next year is
100000
probability that the person will not die in the next year?
A. 99%
B. 0.00365
C. 0.99635
D. 99635
The probability that the person will not die in the next year is 0.99635, the correct option is C.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
The probability that a person will die in the next year =100000
Now,
The probability that a person will die in the next year is given as 0.00001 (or 1/100000).
To find the probability that the person will not die in the next year, we can subtract the probability of dying from 1
Probability of not dying = 1 - Probability of dying
Probability of not dying = 1 - 0.00001
Probability of not dying = 0.99999
None of the options provided match this answer exactly, but the closest 0.99635.
Therefore, by the probability the answer will be 0.99635.
