A city's population is 12,000 and grows at 2.6% rate. What will the population be after 25 years? A city's population is 230,000
Levart [38]

Answer:

The 12000 City would become 22,986 people, while the 230,000 city would become a population of 124,223.

Step-by-step explanation:

1st Part:

=12000⋅(0.026000000000000002⋅25)

=12000(2.718281828459045)(0.65)

=22986

2nd Part:

=230000⋅(−0.044000000000000004⋅14)

=230000(2.718281828459045)(−0.616)

=124223

If these are the missing parts: 

What is the quadrilateral?

a.rhombus
b. rectangle
c. trapezoid
<span>d. square

The quadrilateral formed by the </span><span>two equilateral triangles taped together is A. RHOMBUS.

Rhombus has equal sides but its is different from a square because it looks like a diamond. 
Rhombus also have parallel opposite sides and equal opposite angles. </span>

Im being timed<br>which number line represents the solution set for the inequality?​
Ludmilka [50]

Answer:

The solution is:

-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Step-by-step explanation:

Given the inequality

-\frac{1}{2}x\ge 4

Let us solve the inequality

-\frac{1}{2}x\ge 4

Multiply both sides by -1 (reverse the inequality)

\left(-\frac{1}{2}x\right)\left(-1\right)\le \:4\left(-1\right)

Simplify

\frac{1}{2}x\le \:-4

Multiply both sides by 2

2\cdot \frac{1}{2}x\le \:2\left(-4\right)

Simplify

x\le \:-8

Thus, the solution is:

-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}

The number line graph of the solution is also attached below.

From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

Use the given data to find the equation of the regression line. x 44 44 11 11 55 y 66 55 negative 1−1 negative 3−3 88 ModifyingA
Temka [501]

Answer:

y=1.98 x -24.34

Step-by-step explanation:

Assuming the following data

X: 44, 44, 11, 11, 55

Y: 66, 55, -1, -3, 88

We want to find a linear model Y= mx +b

For this case we need to calculate the slope with the following formula:

m=\frac{S_{xy}}{S_{xx}}

Where:

S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}

S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}

So we can find the sums like this:

\sum_{i=1}^n x_i =44+44+11+11+55=165

\sum_{i=1}^n y_i =66+55-1-3+88=205

\sum_{i=1}^n x^2_i =7139

\sum_{i=1}^n y^2_i =15135

\sum_{i=1}^n x_i y_i =10120

With these we can find the sums:

S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}=7139-\frac{165^2}{5}=1694

S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}=10120-\frac{165*205}{5}=3355

And the slope would be:

m=\frac{3355}{1694}=1.98

Nowe we can find the means for x and y like this:

\bar x= \frac{\sum x_i}{n}=\frac{165}{5}=33

\bar y= \frac{\sum y_i}{n}=\frac{205}{5}=41

And we can find the intercept using this:

b=\bar y -m \bar x=41-(1.98*33)=-24.34

So the line would be given by:

y=1.98 x -24.34
