x = 2 ± \(\sqrt{15}\)
Step-by-step explanation:
x² - 4x - 11 = 0 ( add 11 to both sides )
x² - 4x = 11
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 2)x + 4 = 11 + 4
(x - 2)² = 15 ( take square root of both sides )
x - 2 = ± \(\sqrt{15}\) ( add 2 to both sides )

The following is an example of Partial Initialization of an array. int num]= (88, 92, 75, 95, 82): True False Moving to another question will save this response. hp
Answers
Partial initialization allows us to initialize only some elements of an array, leaving the rest with default values.
The statement you provided, `int num]= (88, 92, 75, 95, 82)`, contains syntax errors and is not a valid example of partial initialization of an array in C or C++.
To understand partial initialization of an array, let's consider a correct example. Suppose we have an integer array named `num` with a size of 10. We want to initialize the first five elements of the array with specific values, and the remaining elements should be set to 0. Here's how partial initialization would look like:
int num[10] = {88, 92, 75, 95, 82};
In this example, we declare an integer array `num` with a size of 10. We provide an initializer list inside curly braces `{}` to initialize the elements of the array. The first five elements are explicitly initialized with values `88`, `92`, `75`, `95`, and `82`. The remaining elements are automatically set to 0 because we haven't provided explicit values for them.
Partial initialization allows us to initialize only some elements of an array, leaving the rest with default values. It's particularly useful when we want to set certain values while keeping others as defaults, such as zero in the case of integers.

two and half of a number added to three quarters of the same number gives you 13.find the number.
Answers
Answer:
52/21
Step-by-step explanation:
Translate the word equation into an algebraic equation as follows:
Let the number be X
two-and-a-half of a number --> (2 1/2) X
2 1/2 = (2 x 2 + 1) = 5/2
So two-and-a-half of a number --> (9/2)X = 9X/2
three-quarters of the same number --> (3/4)X --> 3X/4
two and half of a number added to three quarters of the same number becomes 9X/2 + 3X/4
gives you 13 --> = 13
So we get the equation:
9X/2 + 3X/4 = 13
Multiply both sides by 4 to get rid of the denominators
4.(9X/2) + 4(3X/4) = 4 x 13 = 52
36X/2 + 12X/4 = 52
==> 18X + 3X = 52
==> 21X = 52
==> X = 52/21

Answers
The measures of the angle are 50° and 40°.
What is a complementary angle?In Mathematics and Geometry, a complementary angle refers to two (2) angles or arc whose sum is equal to 90 degrees (90°).
Let the variable x represent the first angle.
Let the expression (90 - x) represent its complement.
By substituting the given parameters into the complementary angle formula, the sum of the angles is given by;
x - (90 - x) = 10
x - 90 + x = 10
2x = 10 + 90
2x = 100
x = 100/2

Answers
The correct answer choice for the MPC (marginal propensity to consume) when the multiplier is 6 is not provided among the options A. 0.16, B. 0.83, C. 0.71, or D. 0.86.
The MPC is calculated as the ratio of the change in consumption to the change in income. When the multiplier is given, we can derive the MPC using the formula MPC = 1 / (1 + MPC). In this case, the multiplier is stated to be 6.
To find the corresponding MPC, we can solve the equation 1 / (1 + MPC) = 6 for MPC.
Rearranging the equation, we have 1 + MPC = 1 / 6. Subtracting 1 from both sides, we get MPC = 1 / 6 - 1 = -5 / 6.
The result MPC = -5 / 6 implies a negative MPC, which does not align with any of the given answer choices.
Additionally, all the answer choices provided (0.16, 0.83, 0.71, and 0.86) are positive values, further confirming that none of them represents the correct MPC when the multiplier is 6.

To compute the values for X* and X**, we need to use the standard normal distribution and the cumulative distribution function (CDF).
Since X follows a normal distribution with mean 100 and standard deviation 20, we can standardize the values using the formula:
Z = (X - μ) / σ
where Z is the standardized value, X is the given value, μ is the mean, and σ is the standard deviation.
a. P(X < X*) = 80%
To find the value X* for which P(X < X*) = 80%, we need to find the z-score corresponding to this probability. Using Excel, we can use the NORM.INV function.
Excel Command: NORM.INV(0.8, 100, 20)
This command calculates the inverse of the cumulative distribution function (CDF) for the standard normal distribution with a probability of 0.8. The mean is set to 100, and the standard deviation is set to 20. The result will give us the value of X*.
b. P(X > X**) = 60%
To find the value X** for which P(X > X**) = 60%, we need to find the z-score corresponding to this probability and then use the formula to calculate X. Since we want the probability of X being greater than X**, we can use the complementary probability (1 - 0.6 = 0.4) to find the z-score.
Excel Command: NORM.INV (0.4, 100, 20)
This command calculates the inverse of the cumulative distribution function (CDF) for the standard normal distribution with a probability of 0.4. The mean is set to 100, and the standard deviation is set to 20. The result will give us the value of X**.

Answers
The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.
The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.
Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.
Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

4. d. as it gets closer to the sun
“Shooting Stars” that streak across the sky in a brief flash of light is Option b) Meteors.
"Shooting stars" are captivating phenomena seen in the night sky. They are commonly mistaken for stars, but they are not stars at all.
Shooting stars, or meteors, are not celestial bodies themselves, but rather the luminous trails created when small space rocks, known as meteoroids, enter Earth's atmosphere at high speeds.
These meteoroids are remnants from comets or asteroids.
When a meteoroid collides with Earth's atmosphere, friction causes it to heat up rapidly.
This intense heat causes the meteoroid to vaporize in a brilliant flash of light, leaving behind a streak across the sky.
This streak is what we commonly refer to as a shooting star or meteor.
Comets, denoted by option (a), are icy bodies that originate from the outer regions of the solar system.
They can produce meteoroids, which in turn create meteors when they enter Earth's atmosphere. However, comets themselves are not what we see as shooting stars.
Meteoroids, as mentioned in option (c), are the actual rocky or metallic fragments that create meteors.
When a meteoroid survives its fiery passage through the atmosphere and lands on Earth's surface, it is referred to as a meteorite, as stated in option (d).
In summary, shooting stars, or meteors, are the dazzling result of meteoroids burning up as they speed through Earth's atmosphere. This captivating display is a reminder of the continuous cosmic activity surrounding our planet, turning the night sky into a canvas of transient and awe-inspiring light shows.

The base of a triangular prism is a right triangle with a base of 10 inches and a height of 24 inches. the height of the prism is 52 inches. find the volume of the prism.
Answers
The volume of the triangular prism, with a base of a right triangle measuring 10 inches by 24 inches and a height of 52 inches, is 6,240 cubic inches.
To calculate the volume of the triangular prism, we need to multiply the area of the base triangle by the height of the prism. The area of a right triangle is given by the formula (base * height) / 2.
First, calculate the area of the base triangle:
Area = (10 inches * 24 inches) / 2
= 120 square inches.
Next, multiply the area of the base triangle by the height of the prism to find the volume:
Volume = Area * Height
= 120 square inches * 52 inches
= 6,240 cubic inches.
Therefore, the volume of the triangular prism is 6,240 cubic inches.

What does the constant 0.9955 reveal about the rate of change of the quantity?
Answers
The model given is:
\(f(t)=290(0.9955)^{60t}\)The term in the parentheses represents the change of rate of the model. If the number is the parentheses is less than 1, we call it exponential decay.
If the number in parentheses is bigger than 1, we call it exponential growth.
In this case, the correct option is "decaying"
The number in parentheses let's call it R, is:
\(R=1-r\)Where r is the rate of change. To find it:
\(\begin{gathered} 0.9955=1-r \\ . \\ r=1-0.9955=0.0045 \end{gathered}\)To convert to percentage, we convert by multiplying by 100::
\(0.0045\cdot100=0.45\%\)The second answer is 0.45%

the mail arrival time to a department has a uniform distribution over 0 to 60 minutes. what is the probability that the mail arrival time is more than 20 minutes on a given day?
Answers
The probability that the mail arrival time is more than 20 minutes on a given day is 2/3.
How do we find the probability?It's nearly impossible to predict the outcomes of many events with a hundred percent certainty. However, we can still tell how likely the events are to happen.
Probability is how likely something is to happen. Probability can also mean a number that indicates the chance or likelihood that a particular event will occur. Probability is always between zero and one. Zero means impossible while one means certain. In most cases, the probability of something to happen is greater than zero and less than one.
Mathematically, we can express probability as P(A) = f/N where
P(A) represents the probability of an event (event A),f represents frequency or number of ways an event can occur, andN represents the total number of possible outcomes.Let P(A) represent the probability that the mail arrival time is more than 20 minutes on a given day, f represent the frequency (60 - 20), and N represent total number of possible outcomes, which is 60.
P(A) = (60 - 20)/60
P(A) = 40/60
P(A) = 4/6
P(A) = 2/3

Step-by-step explanation:
As the square cake was cut in two equal pieces, we have that one side of the rectangle is the double of the other side, so we have that:
2*Length + 2*Width = 45
Length = 2*Width
So using the value of length in the first equation, we have:
4*Width + 2*Width = 45
6*Width = 45
Width = 7.5
Length = 2*Width = 15
So each side of the original cake is equal to the length of the rectangle pieces, that is, 15 inches.
