Answer:

After about 22 years, the population of each community will be approximately 12400

Step-by-step explanation:

Given

[tex]y_1 = 10000(1.01)^x[/tex]

[tex]y_2 = 8000(1.02)^x[/tex]

Required

The population of each community after certain years.

[tex](a)\ x = 12[/tex]

We have:

[tex]y_1 = 10000(1.01)^x[/tex]                                               [tex]y_2 = 8000(1.02)^x[/tex]

[tex]y_1 = 10000(1.01)^{12[/tex]                                              [tex]y_2 = 8000(1.02)^{12[/tex]

[tex]y_1 = 11268.25[/tex]                                                     [tex]y_2 = 10145.93[/tex]

[tex]y_1 \approx 11300[/tex]                                                         [tex]y_2 \approx 10100[/tex]

[tex](b)\ x = 22[/tex]

We have:

[tex]y_1 = 10000(1.01)^{22[/tex]                                              [tex]y_2 = 8000(1.02)^{22[/tex]

[tex]y_1 = 12447.158[/tex]                                                    [tex]y_2 = 12367.83[/tex]

[tex]y_1 \approx 12400[/tex]                                                          [tex]y_2 \approx 12400[/tex]

[tex](c)\ x = 16[/tex]

We have:

[tex]y_1 = 10000(1.01)^{16[/tex]                                              [tex]y_2 = 8000(1.02)^{16[/tex]

[tex]y_1 = 11725.78[/tex]                                                     [tex]y_2 = 10982.28[/tex]

[tex]y_1 \approx 11700[/tex]                                                         [tex]y_2 \approx 11000[/tex]

[tex](d)\ x = 20[/tex]

We have:

[tex]y_1 = 10000(1.01)^{20[/tex]                                              [tex]y_2 = 8000(1.02)^{20[/tex]

[tex]y_1 = 12201.90[/tex]                                                    [tex]y_2 = 11887.60[/tex]

[tex]y_1 \approx 12200[/tex]                                                         [tex]y_2 = 11900[/tex]

Answer:

[tex]36\:\mathrm{in^3}[/tex]

Step-by-step explanation:

The area of a prism is given by the product of the base and the height. In this triangular prism, the area of the either base is:

[tex]A=\frac{1}{2}\cdot 3\cdot 4=6\:\mathrm{in^2}[/tex]

The height is marked as [tex]6[/tex] inches. Thus, the volume of the prism is:

[tex]\frac{1}{2}\cdot 3\cdot 4\cdot 6=\boxed{36\:\mathrm{in^3}}[/tex]

Answer:

Angle1:12

Angle2:168

Step-by-step explanation:

Angle 1+angle 2=180

X-9+8x=180

9x=189

x=21

angle1=21-9=12

Angle2=180-12=168

Answer:

x = 21

so

1 = 12°

2 = 168°

Step-by-step explanation:

solve for x first

9514 1404 393

Answer:

  45 and 225

Step-by-step explanation:

Let x represent the larger number. Then ...

  x - 1/5x = 180

  x = 5/4(180) = 225

  1/5x = 45

The two numbers are 45 and 225.

Answer:

135,590.4 lbs

Step-by-step explanation:

the radius of tank = r = 4 ft

the length of tank = h = 42 ft

the volume of tank truck = π. r².h

= 22/7 × 4² x 42

= 132×16

= 2,112 ft³ (= the volume of milk)

so, the weight of milk =

2,112 × 64.2 = 135,590.4 lbs

[tex]\\ \sf\longmapsto V=\pi r^2h[/tex]

[tex]\\ \sf\longmapsto V=\dfrac{22}{7}(4)^2(42)[/tex]

[tex]\\ \sf\longmapsto V=22(16)(6)[/tex]

[tex]\\ \sf\longmapsto V=22(96)[/tex]

[tex]\\ \sf\longmapsto V=2112ft^3[/tex]

Now

Weight of milk

[tex]\\ \sf\longmapsto 2112(64.2)=135,590lbs[/tex]

Answer:

No, it is not

Step-by-step explanation:

11.5 is the longest side, so it is most probably the hypotenuse

using the formula a²+ b² = c², lets input the numbers

5² + 7² = 11.5²

25 + 49 = 132.25

74  ≠ 132.25

So this is wrong

Dummy variables are those variables where we use 0 and 1 to represent categorical variables, like yes or no, etc.

student lives on campus is a dummy variable because it can be answered as yes or no

student’s parents graduated from college is a dummy variable because it can be answered as yes or no

Student GPA and number of hours are not dummy because these are not categorical variable

Student is dating is dummy variable because it can be answered as yes or no

Answer:

Step-by-step explanation:

10% of 30,000 is 3,000

30,000 - 3,000 = 27,000

Answer:

Hence, the confidence interval is [tex](63.517,74.483)[/tex] gallons.

Given :

Sample size[tex]=36[/tex]

Sample mean [tex]=69[/tex] gallons

Standard deviation [tex]=20[/tex] gallons

So, the standard error [tex]=\frac{20}{\sqrt{36}}=20/6=3.33[/tex]

Confidence level [tex]=95\%[/tex]

To find :

The [tex]95\%[/tex] confidence interval for the number of gallons of carbonated beverages consumed per year by Americans.

Explanation :

[tex]\because[/tex] Confidence interval [tex]=(\text{Sample mean}-\text{margin error},\text{Sample mean}+\text{margin error})[/tex]

Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]

Here, [tex]\alpha=1-95\%=1-0.95[/tex]

      [tex]\Rightarrow \alpha=0.05\Rightarrow \frac{\alpha}{2}=0.025[/tex]

    [tex]Z_{\frac{\alpha}{2}}=Z_{0.025}=1.645[/tex] from the [tex]z-[/tex]table.

So, Margin error [tex]=Z_{\frac{\alpha}{2}}\times\frac{\sigma}{\sqrt{n}}[/tex]

                         [tex]=1.645\times\frac{20}{6}=1.645\times3.33[/tex]

                        [tex]=5.483[/tex]

Therefore, the confidence interval is:

   [tex](69-5.483,69+5.483)[/tex]

[tex]=(63.517,74.483)[/tex] gallons.
