Answer:
7500
Step-by-step explanation:
1 year= 2500
3 years= x
So we got
2500 × 3 = 7500
The population after another three years will be 15,625.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
Assume a populace becomes as per a strategic model with starting populace of 1,000 and conveying limit of 10,000.
If the population grows to 2500 after one year. Then the increasing factor is given as,
b = 2,500 / 1,000
b = 2.5
Then the equation is given as,
y = 1,000 × (2.5)ˣ
Then the population after another three years will be given as,
y = 1,000 × (2.5)³
y = 1,000 × 15.625
y = 15,625
The population after another three years will be 15,625.

situation: the ratio of my friends that like basketball to the ratio of my friends that don’t like basketball is 41:30. This means that 41 out of my 71 friends like basketball. 57.74% of my friends like basketball and 42.26% of my class doesn’t like basketball.
question: if the ratio stayed constant for the whole school, what would your equivalent ratio be with a new total of 310 total people?
Answer:
17.9:13
Step-by-step explanation:
I know this because in order to find the percentage of 310, you must mutiply 310 by the percentage.
The number of students who like basketball:
310 x 0.05774 = 17.9
The number of students who don't like basketball:
310 x 0.04726 = 13

According to the National Center for Health Statistics, in 1990, 28% of babies in the United States were born to parents who were not married. Throughout the 1990s, this increased by approximately 0.6% per year. If this trend continues, in which year will 31% of babies be born out of wedlock?
Answer:
The year is [tex]b = 1995[/tex]
Step-by-step explanation:
From the question we are told that
The percentage of the number of babies born out of wedlock in 1990 is k = 28%
The percentage by which the number increase per year is i = 0.6%
The percentage of of the number of babies born out of wedlock considered is a = 31%
Generally the difference in between the percentage in 1990 and the percentage considered is
[tex]d = a - k[/tex]
=> [tex]d = 31 - 28[/tex]
=> [tex]d = 3\%[/tex]
Generally the number of year require for the percentage to be equal to 31% is mathematically represented as
[tex]n = \frac{3\%}{0.6\%}[/tex]
=> [tex]n = 5\ years[/tex]
Generally the year which the considered percentage will be attained is
[tex]b = 1990 + n[/tex]
=> [tex]b = 1990 + 5[/tex]
=> [tex]b = 1995[/tex]

20. John Navarro is a salesperson in the appliance department at Morris
Appliance, Inc. He is guaranteed a minimum salary of $185 per week, or
5.5 percent of his total sales—whichever is greater. What is his gross pay
for a week in which his total sales were $3,422?
Answer:
$373.21Step-by-step explanation:
Step one:
weekly pay = $185
commission= 5.5% of sales= 0.055
let the sale be x
and his gross pay be represented by y
hence the expression for the total/gross pay is
y=0.055x+185
Step two:
Required is the gross pay y for x=3422
substituting we have
y=0.055*3422+185
y=188.21+185
y=373.21
Hence for a sale of $3,422 made his gross pay is $373.21

Step-by-step explanation:
To find x, you need to add all of the other sides and subtract it from the perimeter. 5.62 + 5.62 + 3.65 = 14.89.
23.59 - 14.89 = x, so x = 8.7

1. A statistician calculates that 8% of Americans are vegetarians. If the statistician is correct, what is the probability that the proportion of vegetarians in a sample of 569 Americans would be greater than 9%?2.The mean points obtained in an aptitude examination is 166 points with a standard deviation of 19 points. What is the probability that the mean of the sample would differ from the population mean by less than 1.1 points if 66 exams are sampled?
Answer:
1) the probability that the proportion of vegetarians in the sample would be greater than 9% is 0.1902
2) the probability that the mean of the sample would differ from the population mean by less than 1.1 points in the is 0.3616
p( /x" - u/ < 0.47 ) = 0.3616
Step-by-step explanation:
1)
Given that;
p = 8% = 0.08 and n = 569
what is the probability that the proportion of vegetarians in a sample of 569 Americans would be greater than 9% (0.09)
that is;
p( p" > 0.09) = ?
p( p" > 0.09) = p( z > [(0.09 - 0.08)/(√((0.08(1 - 0.08))/569))] )
= p( z > (0.01 / 0.0114))
= p ( z > 0.8772)
= 0.1902
Therefore the probability that the proportion of vegetarians in the sample would be greater than 9% is 0.1902
2)
Given that;
mean points obtained in an aptitude examination u = 166
standard deviation α = 19
sample size n = 66
x" - u = 1.1
first we say
x-score = (x" - u) / (α/√n) = 1.1 / (19/√66) = 1.1 / 2.3387 = 0.47
p( -0.47 < z < 0.47 )
= p( z < 0.47) - p( z < - 0.47)
= 0.6808 - 0.3192
= 0.3616
Therefore the probability that the mean of the sample would differ from the population mean by less than 1.1 points in the is 0.3616
p( /x" - u/ < 0.47 ) = 0.3616

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in dollars and C be the charge of the online auction. Explain whether the solutions A=−5 and C=1.1 are viable.
The solutions are not viable because the amount charged is not a whole number.
The solutions are viable because the amount of the sale is an integer.
The solutions are viable because the amount charged is positive.
The solutions are not viable because the amount of the sale cannot be negative
Answer:
The solutions are not viable because the amount of the sale cannot be negative
Step-by-step explanation:
We are told that;
Let A be the amount of the sale in dollars and C be the charge of the online auction
This means that both values of A and B should be non-negative integers.
Now, we are also told that An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale.
We can conclude that the solution is not viable because the amount of sale of -1.1 cannot be negative.
| 3x + 2 |= 4x + 5
explain how to solve it please
Answer:
x = -3
Step-by-step explanation:
Subtract 2 from both sides of the equation.
3x + 2 = 4x + 5
3x + 2 - 2 = 4x + 5 - 2
Step 2.
Simplify. Subtract the numbers 3x =4x + 3
Now subtract 4 from both sides.
Combine like terms -x = 3
Divide both sides of the equation.
Cancel terms that are in both the numerator and denominator
Divide the numbers
And that's how X = -3
