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.

Suppose you are interested in using regression analysis to estimate a student's GPA using the following independent variables: the student is a freshman, the student's ACT score, number of hours per week the student studies, the student's GPA in the previous term, the student's GPA in high school, and the number of classes skipped per week. Which of the following independent variables are indicator (dummy) variables?
a. the student lives on campus
b. the student's parents graduated from college
c. the student's GPA in high school
d. the number of hours spent in class per week
e. the student is dating
f. number of alcoholic drinks per week the student consumes
g. None of these
Answer:
B
Step-by-step explanation:
The options a. the student lives on campus b. the student's parents graduated from e.college Student is dating are dummy variables.
What is dummy variable?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
number of alcoholic drinks is not dummy variable because it is not categorical variable.

D.20
years, the population of each community will be approximately_____
A.18,270
B.14,400
C.16,200
D.11,300
people.
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]

is triangle abc a right triangle? AB=5, BC=7, AC=11.5
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

A cylinder has a volume of 2512 cubic feet. If the height of the cylinder is 50 feet, what is the radius of the cylinder? Use 3.14 for pi.
Answer:
4 ft.
Step-by-step explanation:
2512 = 3.14 * r^2 * 50
r^2 = 2512 / (3.14 * 50)
r^2 = 16
r = 4 ft.

Answer:

Step-by-step explanation:
I need this answer pls. 100 points
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]

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]

1. The U.S. Department of Agriculture reported a random sample of 36 Americans consumed an average of 69 gallons of carbonated beverages per year. Assume that the population standard deviation is 20 gallons. Find the 95% confidence interval for the number of gallons of carbonated beverages consumed per year by Americans.(round the final answer to 3 decimal places.)
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.
