Answer:
y=2
Step-by-step explanation:
x+2=5
x= 5-2
x= 3
2x+y=8
2×3+y=8
6+y=8
y=8-6
y=2
Answer:
y=2
Step-by-step explanation:
First solve x+2=5 to find x.
x+2=5
-2 -2
x=3. Substitute x=3 into 2x+y=8.
(2 x 3) + y = 8
Now solve.
6 + y = 8
-6 -6
y=2.

Answer:
d. tan (35) = [tex]\frac{x}{10}[/tex]
Step-by-step explanation:
You must memorize the definitions of all the trig functions.
Tan of an angle = opposite side/adjacent side
In your case, the opposite side of the 35° angle is x and the adjacent side of the 35° angle is 10
So, tan 35 = x/10
The mayor of a town has proposed a plan for the annexation of a new community. A political study took a sample of 900900 voters in the town and found that 42B% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is above 388%. Find the value of the test statistic. Round your answer to two decimal places.
Answer:
The value of the test statistic is 2.47.
Step-by-step explanation:
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the expected mean, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
For a proportion p, we have that:
[tex]s = \frac{\sigma}{\sqrt{n}} = \sqrt{\frac{p(1-p)}{n}}[/tex]
A political study took a sample of 900 voters in the town and found that 42% of the residents favored annexation.
This means that [tex]X = 0.42, n = 900[/tex]
Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is above 38%
This means that the expected is [tex]\mu = p = 0.38[/tex]
So
[tex]s = \frac{\sigma}{\sqrt{n}} = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.38*0.62}{900}} = 0.0162[/tex]
Find the value of the test statistic
[tex]t = \frac{X - \mu}{s}[/tex]
[tex]t = \frac{0.42 - 0.38}{0.0162}[/tex]
[tex]t = 2.47[/tex]
The value of the test statistic is 2.47.

A Cylinder has a radius of 5 cm and a height of 17 cm, what is the volume of the cylinder.
Hello!
[tex]\large\boxed{V = 425\pi cm^{3}}[/tex]
Use the following equation to solve for the volume of a cylinder:
V = πr²h, where:
r = radius
h = height
Plug in the given radius and height:
V = π(5)² · 17
Solve:
V = π(25 · 17)
V = 425π ≈ 1334.5 cm³
In a gambling game, you roll 2 die and if you toss 2 sixes, you win $100, otherwise you lose $5.
a. What is the chance you win?
b. What is the expected value of the game?
Answer:
a. [tex]\frac{1}{36}[/tex] chance you win.
b. The expected value of the game is -$2.08.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
You roll 2 die and if you toss 2 sixes
For each roll, 6 possible values, 1 of which is 6. So the probability of rolling two sixes is:
[tex]p = (\frac{1}{6})^2 = \frac{1}{36}[/tex]
a. What is the chance you win?
[tex]\frac{1}{36}[/tex] chance you win.
b. What is the expected value of the game?
1/36 probability of winning 100.
35/36 probability of losing 5. So
[tex]E = \frac{1}{36}*100 - \frac{35}{36}*5 = \frac{100 - 175}{36} = -\frac{75}{36} = -2.08[/tex]
The expected value of the game is -$2.08.

Select the equation that has no real solution.
Answer:
12x + 15 = 12x - 15 can not be solved.
We can not find out what x equals.
Step-by-step explanation:
You can solve - 5x - 25 = 5x + 25
x = - 5
You can solve 7x + 21 = 21
x = 0
You can solve 12x + 15 = 3(4x + 5)
x = AllRealNumbers
That leaves 12x + 15 = 12x - 15
This equation can not be solved

Given the system of linear equations Part A: Graph the system of linear equations. Part B: Use the graph created in Part A to determine the solution to the system. Part C: Algebraically verify the solution from Part B.
We have:
The system of linear equations:
x+6y=6
y=1/3 x−2
Part A: Graph is shown in the picture.
Part B: The intersection point is (6, 0)
x = 6
y =0
Part C: By substitution method.
x = 6
y = 0
Thus, the solution to the system of linear equations x+6y=6 and y=1/3 x−2 is x = 6 and y = 0.

The graph of the system of linear equations is represented below.
The solution for the equations x+6y=6 and y= 1/3 x - 2 are x = 6 and y = 0.
What is an equation?A set of variables called an equation is one in which two mathematical expressions are equivalent to one another.
The given system of linear equations,
x+6y=6 (1)
And, y= 1/3 x - 2 (2)
Part A : The graph of the equations shown below:
Part B :
The lines intersect each other at (6, 0)
Therefore, the solution for the equations are x = 6 and y = 0.
Part C:
Substitute the value of x= 6 in the equation (1),
6 + 6y = 6
y = 0.
Also substitute the value of x = 6 in equation (2)
y = (1/3)x6 - 2
y = 2 - 2
y = 0

State the domain of the rational function. (5 points)
f(x) = sixteen divided by quantity thirteen minus x
All real numbers except 13.
All real numbers except -16 and 16.
All real numbers except -13 and 13.
All real numbers except 16.
Answer:
Step-by-step explanation:
Domain is the set of all values of x where the function is defined. For this function the only limitation upon x exists when the denominator would equal zero, because division by zero is undefined. So the denominator 13-x cannot equal zero thus x cannot equal 13. Thus the domain is all real numbers except 13.
In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Eighteen randomly selected plots of land were treated with fertilizer A. The average yield, in pounds, was 457 with a standard deviation of 38. Twelve randomly selected plots were treated with fertilizer B. The average yield was 394 pounds with a standard deviation of 23. Find a 99% confidence interval for the difference between the mean yields for the two fertilizers. (Round down the degrees of freedom to the nearest integer and round the final answers to two decimal places.)
The 99[tex]\%[/tex] confidence interval for the difference between the mean yields for the two fertilizers is (32.11, 93.89).
A confidence interval is a range of values that provides an estimate of the unknown population parameter with a certain level of confidence.
Given that
Sample 1:
Sample mean, [tex]\bar{X_1}[/tex] = 457,
Sample size, [tex]n_1[/tex] = 18,
Standard deviation, [tex]s_1[/tex] = 38.
Sample 2:
Sample mean, [tex]\bar{X_2}[/tex] = 394,
Sample size, [tex]n_2[/tex] = 18,
Standard deviation, [tex]s_2[/tex] = 23.
Point estimate = [tex]\bar{X_1}[/tex] - [tex]\bar{X_2}[/tex]
= 457 - 394
= 63.
[tex]Standard Error=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2} }\\[/tex]
[tex]=\sqrt{\frac{38^2}{18}+\frac{23^2}{18} }\\=11.14924[/tex].
Level of significance, α = 0.01 (given that 99[tex]\%[/tex] confidence interval).
Degrees of freedom = [tex]\dfrac{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2})^2 }{\frac{(\frac{s_1^2}{n_1})^2}{n_1-1} + \frac{(\frac{s_2^2}{n_2})^2}{n_2-1} }[/tex] = 28.
Critical values:
[tex]t_\frac{\alpha}{2} = \pm2.771[/tex]
The confidence interval is
[tex](\bar{X_1}-\bar{X_2})\pm t_\frac{\alpha}{2}\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2} }[/tex]
[tex]= 63 \pm 2.771 \times 11.14924\\=63 \pm 30.89\\=(63-30.89,63+30.89)\\=(32.11,93.89)[/tex]
Hence, the confidence interval is (32.11, 93.89).
