=> C₁ = 1Therefore, the equation of y is: y = 4x³ + 1.For a more in-depth and better explanation, here are 150 words: A second derivative represents the rate of change of the first derivative with respect to x.

Therefore, if we have a second derivative of y with respect to x, we can integrate it twice to get a function of y with respect to x. Given y''(x) = 12x², we can integrate it once to obtain y'(x) = 4x³ + C₁, where C₁ is a constant. We integrate y'(x) once again to get y(x) = x⁴ / 4 + C₁x + C₂, where C₂ is another constant.

The ordered pair of a unit circle is represented as:

\((x,y) \to (\sin(\theta),\cos(\theta))\)

The point where the terminal side of \(\tehta\)\(\theta\) intersect with the unit circle is: 240

The given parameter can be represented as:

\((x,y) \to (-\frac{\sqrt 3}{2},-\frac{1}{2})\)

This means that:

\(\sin(\theta) = -\frac{\sqrt 3}{2}\)

\(\cos(\theta) = -\frac{1}{2}\)

Let the angle between the x-axis and the terminal side be \(\alpha\)

So, we have:

\(\theta = 180 + \alpha\)

Using \(\cos(\theta) = -\frac{1}{2}\)

The equation becomes

\(\cos(180 + \alpha) = -\frac{1}{2}\)

Apply cosine formula

\(\cos(180)*\cos(\alpha) - \sin(180)*\sin(\alpha) = -\frac{1}{2}\)

\(-1*\cos(\alpha) - 0*\sin(\alpha) = -\frac{1}{2}\)

\(-1*\cos(\alpha)= -\frac{1}{2}\)

Divide both sides by -1

\(\cos(\alpha)= \frac{1}{2}\)

Take arccos of both sides

\(\alpha= \cos^{-1}(\frac{1}{2})\)

\(\alpha= \cos^{-1}(0.5)\)

\(\alpha= 60\)

Recall that:

\(\theta = 180 + \alpha\)

\(\theta = 180 +60\)

\(\theta = 240\)

The statement about regression line that is true is "it indicates a linear relationship between dependent variable and independent variable(s)."

In statistics, regression is a method of modeling the connection between a dependent variable (also known as a response variable) and one or more independent variables (also known as explanatory variables or predictors). It's also known as a linear regression model.

A regression model is established in order to identify the linear relationship between the dependent variable and one or more independent variables. The line of best fit is represented by the regression line in a simple linear regression model, which represents the relationship between the dependent variable and independent variable(s).

The line of best fit is determined by minimizing the sum of the squares of the residuals (errors). The objective of the regression model is to obtain a relationship between the dependent variable and the independent variable that explains the variance of the dependent variable based on the independent variable(s).

Hence, the correct option is: it indicates a linear relationship between dependent variable and independent variable(s).

The least expensive computer after the 20% discount would be $400.

To calculate the price of the least expensive computer after the 20% discount, we need to find 20% of the original price and subtract it from the original price.

Let's assume the original price of the least expensive computer is x. The discount of 20% can be calculated as 0.20 * x. To find the discounted price, we subtract the discount from the original price: x - 0.20 * x = 0.80 * x.

Since we know that the cost of the least expensive computer ranges from $500 to $1000, we can substitute x with $500 and calculate the discounted price: 0.80 * $500 = $400. Therefore, the least expensive computer after the 20% discount would be $400.

The y=x(1-x)-(1-x²) is a linear value that is not absolute.

Simplifying,

y=x(1-x)-(1-x²)

y=x-x²-1+x²

y=x-1

Thus, it is a linear equation with a negative value therefore it is not an absolute value.

Ax+By=C is the general form of a two-variable linear equation. When the equation is written in this manner, it is quite simple to obtain both segments (x and y).

Any polynomial that can be rewritten in the canonical form is a quadratic equation. where x represents an unknown quantity and a, b, and c represent known quantities, with a = 0. This indicates that f(x) = 0 is the root of function f(x) = ax2 + bx + c, which is the answer to the quadratic equation ax2 + bx + c = 0.

To determine the number of ways to select a committee of three faculty members and two students from a group of five faculty and seven students, we need to calculate the combination of faculty members and students separately and then multiply the results.

The number of ways to select three faculty members from a group of five is given by the combination formula:

C(5, 3) = 5! / (3!(5 - 3)!) = 10

Similarly, the number of ways to select two students from a group of seven is given by:

C(7, 2) = 7! / (2!(7 - 2)!) = 21

To find the total number of ways to select a committee consisting of three faculty members and two students, we multiply these two values:

Total ways = 10 * 21 = 210

Therefore, there are 210 ways to select a committee of three faculty members and two students from the given group.

a) When selecting 9 spheres at random with substitution, the probability of selecting 1 Blue, 3 white, 2 green, and 3 red can be calculated as follows:

The probability of selecting 1 Blue is (2/17), the probability of selecting 3 white is\((3/17)^3\), the probability of selecting 2 green is \((5/17)^2\), and the probability of selecting 3 red is \((7/17)^3\). Since these events are independent, we can multiply these probabilities together to get the overall probability:

\(P(1 Blue, 3 white, 2 green, 3 red) = (2/17) * (3/17)^3 * (5/17)^2 * (7/17)^3\)

b) When selecting 9 spheres at random without substitution, the probability calculation is slightly different. After each selection, the total number of spheres decreases by one. The probability of each subsequent selection depends on the previous selections. To calculate the probability, we divide the number of favorable outcomes by the total number of possible outcomes at each step.

The probability of selecting 1 Blue without replacement is (2/17), the probability of selecting 3 white without replacement is (\(3/16) * (2/15) * (1/14)\), the probability of selecting 2 green without replacement is\((5/13) * (4/12)\), and the probability of selecting 3 red without replacement is\((7/11) * (6/10) * (5/9)\). Again, we multiply these probabilities together to get the overall probability.

\(P(1 Blue, 3 white, 2 green, 3 red) = (2/17) * (3/16) * (2/15) * (1/14) * (5/13) * (4/12) * (7/11) * (6/10) * (5/9)\)

The length of the ladder is 25 feet.

To find the length of the ladder, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the ladder represents the hypotenuse, and the distance from the house to the ladder (15 ft) is one of the other sides.

In this problem, the top of the ladder is 20 ft from the ground (a) and the bottom is 15 ft from the side of the house (b). We need to find the length of the ladder (c).

According to the Pythagorean theorem:
a² + b² = c²

Substitute the given values:
(20 ft)² + (15 ft)² = c²
400 + 225 = c²
625 = c²

Now, take the square root of both sides to find the length of the ladder (c):
√625 = c
25 = c

Answer:

I believe it is 16 because 8* the two of 200 is 16.

The statement is true. If S, U, and W are subspaces of V such that S+W=U+W, then S=U.

To prove the statement, we need to show that if S+W=U+W, then S=U.

Suppose S+W=U+W. Let x be an arbitrary element in S. Since x is in S, we know that x is in S+W. And since S+W=U+W, x must also be in U+W. This means that x can be expressed as a sum of vectors, where one vector is from U and the other vector is from W.

Now, let's consider the vector x as a sum of two vectors: x=u+w, where u is in U and w is in W. Since x is in U+W, it must also be in U. This implies that x=u, and since x was an arbitrary element in S, we can conclude that S is a subset of U.

Similarly, if we consider an arbitrary element y in U, we can express it as y=s+v, where s is in S and v is in W. Since y is in U+W, it must also be in S+W. Therefore, y=s, and since y was an arbitrary element in U, we can conclude that U is a subset of S.

Since S is a subset of U and U is a subset of S, we can conclude that S=U. Thus, the statement is proven, and if S+W=U+W, then S=U.

A Type I error is the incorrect rejection of a true null hypothesis. A Type II error is the failure to reject a false null hypothesis. The level of significance (alpha) determines the trade-off between these two types of errors.

The p-value is used to help determine whether or not the null hypothesis is statistically significant, which is used to make decisions based on sample data. If the p-value is less than or equal to the alpha level, it is considered significant, and the null hypothesis is rejected.

If the p-value is greater than the alpha level, it is not significant, and the null hypothesis is not rejected. Large p-values indicate that there is insufficient evidence to reject the null hypothesis. An alpha level is the probability of making a Type I error, which is the likelihood of rejecting the null hypothesis when it is true. The level of alpha is determined by the researcher and is usually set at 0.05 or 0.01.

For a result to be statistically significant, it means that it is unlikely that the result occurred due to chance. The significance level (alpha level) must be lower than the p-value to consider the result significant.

A 95% confidence interval corresponds to a two-sided hypothesis test at an alpha level of 0.05. A 90% confidence interval corresponds to a one-sided hypothesis test at an alpha level of 0.1.A Type I error is the incorrect rejection of a true null hypothesis.
