U.S. Population can be modeled by the function f(x)=165.6x^1.345, where f(x) is in thousand and x is the number of year after 1800. What is f(50) and what does it mean?
Answers
Answer:
f(50) = 31928.24 thousands
Therefore, it means that the US population in year 1850 is 31928.24 thousands
Step-by-step explanation:
Given the function;
f(x)=165.6x^1.345
Where;
f(x) is in thousand and
x is the number of year after 1800
To determine f(50), we will substitute x = 50 into the function of f(x);
f(50)=165.6(50)^1.345
f(50) = 31928.24 thousands
Since f(50) is the US population in year 1800+50 = 1850
Therefore, the US population in year 1850 is 31928.24 thousands
In the Kite Club, there are a total of 17 kids. There are 5 more girls than boys. Write two equations and graph to find the number of girls in the club.
Answers
Answer:
6 boys and 11 girls
Step-by-step explanation:
hello,
let 's note x the number of boys and y the number of girls, we can write two equations
"there are a total of 17 kids"
(1) x + y = 17
"There are 5 more girls than boys"
(2) y = x + 5
We can replace (2) in (1) it comes
x + x + 5 = 17
<=> 2x = 17-5 = 12
<=> x = 6
and then y = 11
So, there are 6 boys and 11 girls
graphs below

The number of girls in the club is 6
What is an Equation ?An equation is a mathematical statement formed from two algebraic expression when equated by an equal sign.
It is given that
Total Kids = 17
Let the number of boys be x
There are 5 more girls than boys
Let number of girls be y
y = x+5
The number of girls = x +5
x +y = 17
The graph is plotted and is attached with the answer.
The intersection of the graph gives us the total number of girls and boys
(6,11) is the point of intersection and therefore
Number of boys = 6
No. of girls = 11

Step-by-step explanation:
PA is said to be the difference between two consecutive terms. The PA is always the same for these terms. It is also called the (r) ratio.
A) (1, 1, 1, 1, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 1
2nd term = 1
PA = 1-1
PA = 0
B) (-1, 0, 1, 2, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = -1
2nd term = 0
PA = 0- (-1) = 0+1
PA = 1
C) (12, 48, 84, 120, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 12
2nd term = 48
PA = 48 - 12
PA = 36
D) (101 , 202, 303, 404, ...)
PA = 2nd term - 1st term = 3rd term - 2nd term
Using the 1st and second term
1st term = 101
2nd term = 202
PA = 202 -101
PA = 101

A set of shirt prices are normally distributed with a mean of 45 dollars and a standard deviation of 5 dollars. What proportion of shirt prices are between 37 dollars and 59.35 dollars? You may round your answer to four decimal places.
Answers
Answer:
0.9432
Step-by-step explanation:
Given that
[tex]\\Mean (\mu)= 45[/tex]
[tex]Standard\;Deviation (\sigma)= 5[/tex]
Based on this, the proportion of the shirt price between the given range is
As we know that
For 37 dollars
[tex]z_{ score } = \frac{x-\mu}{\sigma}[/tex]
[tex]z = \frac{37.0-45.0}{5.0}[/tex]
[tex]z_1 = -1.6[/tex]
For 59.35 dollars
[tex]\\ z = \frac{59.35-45.0}{5.0} \\[/tex]
[tex]z_2 = 2.87[/tex]
This results into
= P(37.0 < x < 59.35)
= P(-1.6 < z < 2.87)
= P(Z < 2.87) - P(Z < -1.6)
So,
= P(37.0 < x < 59.35)
= 0.9979 - 0.0547
= 0.9432

Answers
Answer:
x = -2, y = 3
Step-by-step explanation:
Given equations are,
4x + 5y = 7 ---------(1)
3x - 2y = -12 ----------(2)
Multiply equation (1) by 3
12x + 15y = 21 ------(3)
Multiply equation (2) by (-4)
-12x + 8y = 48 --------(4)
Now add equations (3) and (4),
(12x + 15y) + (-12x + 8y) = 21 + 48
(12x - 12x) + (15y + 8y) = 69
23y = 69
y = 3
From equation (2),
3x - 2(3) = -12
3x - 6 = -12
3x = 6 - 12
x = -2
Therefore, x = -2 and y = 3 will be the answer.

Lets the two number are x and [tex]\dfrac{1}{x}[/tex]. Then [tex]\dfrac{1}{x}[/tex] Is a multiplicative inverse or reciprocal of x. Since when we multiply both the numbers we get their product is 1.
Hence, for any non-zero number "x" its multiplicative inverse is denoted as [tex]\dfrac{1}{x}[/tex].
We can say, if two numbers x and [tex]\dfrac{1}{x}[/tex] Satisfies the equation [tex]x\times\dfrac{1}{x}=1[/tex] Then they are reciprocals or multiplicative inverses of each others.
