QUESTION: A 30minute radio program, the entertainment portion lasts 2 minutes longer than 3 times the duration of the commercial portion. How much is devoted to commercials during the 30 minutes
Answer:
Step-by-step explanation:
we know that the total time of the show is 30 minutes.
commercial part = 3x+2
entertainment part = y
also we know that y = 3x +2
y + 3x+2 = 30
we can also say that
2(3(x) +2) = 30
so then
6x +4 = 30
6x = 26
x = 4\(\frac{1}{3}\)
4\(\frac{1}{3}\) is the time in minutes for commercials
X^2+9x+20/x+3 • x^2-x-12/x^2+3x-4
What is the product in simplest form? State any restrictions on the variable
To find the product, we need to first factor the numerators and denominators of both fractions:
x^2 + 9x + 20 = (x + 5)(x + 4)
x^2 - x - 12 = (x - 4)(x + 3)
x^2 + 3x - 4 = (x + 4)(x - 1)
Substituting these into the expression, we get:
[(x + 5)(x + 4)/(x + 3)] * [(x - 4)(x + 3)/(x + 4)(x - 1)]
Now, we can simplify the product by cancelling out common factors:
[(x + 5) * 1/(x - 1)] * [(x - 4) * 1/1]
= (x + 5)(x - 4)/(x - 1)
So the product in simplest form is (x + 5)(x - 4)/(x - 1).
However, there is a restriction on the variable because the expression involves division by (x + 3), (x - 1), and (x - 4). Therefore, x cannot be equal to -3, 1, or 4, since these values would make the denominators zero and the expression undefined.

What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that the sides of the triangles are, 90, 55, and 50.
The value of angle x will be calculated as,
c² = a² + b² - 2abcosx
90² = 55² + 50² - ( 2 x 55 x 50 cosx)
8100 - 5525 = -5500cosx
cosx = -2575 / 5500
x = cos⁻¹(-0.46)
x = 117°

The percentage of the total mattresses that are not extra firm non-memory foam mattresses is 17%.
Let's break down the information step by step to find the percentage of the total mattresses that are not extra firm non-memory foam mattresses.
Let:
M = Total number of mattresses
MF = Memory foam mattresses
EF = Extra firm mattresses
MF&EF = Memory foam and extra firm mattresses (extra firm memory foam mattresses)
From the given information, we have:
1. 75% of the mattresses are memory foam: MF = 0.75 * M
2. 20% of the mattresses are extra firm: EF = 0.20 * M
3. 12% of the total mattresses are extra firm memory foam: MF&EF = 0.12 * M
Now, to find the percentage of mattresses that are not extra firm non-memory foam, we need to subtract the number of memory foam, extra firm, and extra firm memory foam mattresses from the total number of mattresses:
Not extra firm non-memory foam mattresses = M - (MF + EF - MF&EF)
Plugging in the values:
Not extra firm non-memory foam mattresses = M - (0.75 * M + 0.20 * M - 0.12 * M)
Not extra firm non-memory foam mattresses = M - (0.83 * M)
Now, the percentage of not extra firm non-memory foam mattresses is:
Percentage = (Not extra firm non-memory foam mattresses / M) * 100
Percentage = ((M - 0.83 * M) / M) * 100
Percentage = (0.17 * M / M) * 100
Percentage = 0.17 * 100
Percentage = 17%
So, the percentage of the total mattresses that are not extra firm non-memory foam mattresses is 17%.
The correct option is F. 17.

It is believed that UMD students get less sleep, on average, than the general population. A survey of 500 UMD students is conducted generated a mean of 7.24 hours with a standard deviation of 1.93 hours. We want to compare this to the population distribution of sleep times that has a mean of 8.32 hours with a standard deviation of 1.24. The distribution to be used for this test would be:
Therefore, the distribution used for this test is the standard normal distribution (z-distribution).
To compare the sleep times of UMD students to the population distribution, a hypothesis test can be performed. Specifically, to test if UMD students get less sleep, a one-sample z-test can be conducted.
The distribution to be used for this test would be the standard normal distribution (also known as the z-distribution). This is because we are comparing the sample mean (7.24 hours) to the population mean (8.32 hours) and have information about the population standard deviation (1.24 hours).
By calculating the test statistic using the formula:
z = (sample mean - population mean) / (population standard deviation / √(sample size))
we can determine the z-value and compare it to the critical value from the standard normal distribution to assess the significance of the difference in sleep times between UMD students and the general population.

A person starts walking from home and walks:
5 miles East
4 miles Southeast
6 miles South
3 miles Southwest
4 miles East
Round your answers to 2 decimal places.
This person has walked a total of _____ miles.
Find the total displacement vector for this walk:
If this person walked straight home, they'd have to walk _____ miles.
This person has walked a total of 22 miles. The total displacement vector for this walk is 10.06 miles at an angle of 12.58°. If this person walked straight home, they'd have to walk 10.06 miles.
To find the total displacement vector for this walk, we can use the Pythagorean Theorem to find the magnitude of the displacement vector and the direction of the displacement vector.
First, let's find the magnitude of the displacement vector:
d = √((Δx)² + (Δy)²)
Where Δx is the change in the x-direction and Δy is the change in the y-direction.
Δx = 5 + 4cos(45°) + 0 + 3cos(225°) + 4 = 9.83 miles
Δy = 0 + 4sin(45°) + 6 + 3sin(225°) + 0 = 2.17 miles
d = √((9.83)² + (2.17)²) = √(96.58 + 4.71) = √(101.29) = 10.06 miles
So, the magnitude of the displacement vector is 10.06 miles.
Next, let's find the direction of the displacement vector:
θ = tan⁻¹(Δy/Δx) = tan⁻¹(2.17/9.83) = 12.58°
So, the direction of the displacement vector is 12.58°.
Therefore, the total displacement vector for this walk is 10.06 miles at an angle of 12.58°.
If this person walked straight home, they'd have to walk 10.06 miles.
This person has walked a total of 22 miles. The total displacement vector for this walk is 10.06 miles at an angle of 12.58°. If this person walked straight home, they'd have to walk 10.06 miles.

The solution to the system of equations is x = 1 and y = -2.
We have,
3x - 4y = 11
y + 3x = 1
To solve the system of equations:
3x - 4y = 11
y + 3x = 1
We can use the method of substitution or elimination.
Let's solve it using the elimination method.
Multiply equation 2) by -1 to eliminate the term 3x:
-1(y + 3x) = -1(1)
-y - 3x = -1
Now we have the following system of equations:
3x - 4y = 11
-y - 3x = -1
Add equation 1) and equation 2) together:
(3x - 4y) + (-y - 3x) = 11 + (-1)
3x - 4y - y - 3x = 10
-5y = 10
Divide both sides of the equation by -5:
-5y / -5 = 10 / -5
y = -2
Now substitute the value of y = -2 into equation 2):
-2 + 3x = 1
Add 2 to both sides:
3x = 3
Divide both sides by 3:
3x / 3 = 3 / 3
x = 1
Therefore,

Which correlation coefficient best represents a moderate relationship showing fewer anxiety symptoms.
The correlation coefficient that best represents a moderate relationship showing fewer anxiety symptoms is a negative correlation coefficient.
In a negative correlation, as one variable increases, the other variable decreases. In the context of anxiety symptoms, a negative correlation would indicate that as one factor (e.g., a particular intervention, treatment, or activity) increases, the number or severity of anxiety symptoms decreases. This suggests a moderate relationship between the two variables, indicating that the higher the value of the independent variable, the lower the value of the dependent variable (in this case, fewer anxiety symptoms).
The correlation coefficient ranges from -1 to 1, with -1 representing a perfect negative correlation, 0 representing no correlation, and 1 representing a perfect positive correlation. A correlation coefficient close to -1, but not reaching -1, would be indicative of a moderate negative correlation and would best represent a moderate relationship showing fewer anxiety symptoms.
