Answer:

y=4x+2

Step-by-step explanation:

Approximately 12.5% percentage of the students could be expected to score between 80 and 90.

To determine the percentage of students who could be expected to score between 80 and 90, we need to calculate the z-scores for these scores and use the standard normal distribution.

First, we need to calculate the z-scores for 80 and 90 using the formula:

z = (x - μ) / σ

where x is the individual score, μ is the mean, and σ is the standard deviation. Plugging in the values of μ = 100, σ = 60, and x = 80 or x = 90, we can calculate the z-scores.

For x = 80:

z = (80 - 100) / 60 = -0.3333

For x = 90:

z = (90 - 100) / 60 = -0.1667

Next, we need to find the area under the standard normal distribution curve between these two z-scores. This represents the percentage of students who scored between 80 and 90.

Using a standard normal distribution table or calculator, we can find that the area between -0.3333 and -0.1667 is approximately 0.1210 or 12.1%.

Therefore, approximately 12.5% of the students could be expected to score between 80 and 90.

To find the volume of the glass formed by rotating the shaded region about the y-axis, we can use the method of cylindrical shells.

The volume of a solid of revolution using cylindrical shells is given by the integral:

V = ∫[a,b] 2πx * f(x) * dx

In this case, the function representing the curve that forms the inside of the glass is y = x^4/2. We need to find the limits of integration, a and b, which correspond to the x-values where the shaded region begins and ends.

From the graph, it appears that the shaded region begins at x = -1 and ends at x = 1. So, the limits of integration are -1 to 1.

Now, we can calculate the volume of the glass using the integral formula:

V = ∫[-1,1] 2πx * [tex](x^4/2) * dx[/tex]

V = π * ∫[-1,1] [tex]x^5 dx[/tex]

Using the power rule of integration, we integrate x^5:

V = π * [x^6/6] from -1 to 1

V = π * [[tex](1^6/6) - (-1^6/6)][/tex]

V = π * [(1/6) - (1/6)]

V = π * 0

Therefore, the volume of the glass is 0 cubic units.

The assumption which is not true for multiple linear regression is that there will be a multi-collinearity effect. What is multiple linear regression? Multiple linear regression is a regression method where the response variable is dependent on more than one independent variable. Multiple linear regression is an extension of linear regression, where one response variable is dependent on one independent variable. It helps to determine the nature of the relationship between dependent variables and independent variables in the form of linear equations. It is used to find out the relationship between variables and make predictions based on that relationship. Assumptions of multiple linear regression1. Linearity, It is assumed that the relationship between the independent variables and dependent variables is linear. This implies that as the value of the independent variable changes, the change in the dependent variable is constant.2. Independence, There should be independence among the observations. This implies that there should not be any relationship between the residuals of the observations.3. Homoscedasticity implies that the variance of residuals should remain constant across all levels of the independent variable.4. Multicollinearity, It is the condition where the independent variables are highly correlated with each other. If there is perfect collinearity, it will not be possible to obtain the estimates of regression coefficients.5. Normality, The residuals should follow a normal distribution with mean zero and constant variance. The residuals should be normally distributed and centered on zero. The assumptions that are true for multiple linear regression are: The independent variables are not correlated. The residuals are normally distributed. The relationship between dependent and independent variables is linear. The assumption which is not true for multiple linear regression is that there will be a multi-collinearity effect. Hence, the correct option is D) There will be a multi-collinearity effect.

True. A rational expression is undefined whenever its denominator is zero. This is because division by zero is not defined.

In mathematics, a rational expression is defined as the quotient of two polynomials, where the denominator represents the divisor. When the denominator of a rational expression becomes zero, it results in division by zero, which is undefined. Division by zero is not a valid operation in mathematics, and it leads to an undefined value. Therefore, to determine if a rational expression is undefined, we need to check if its denominator evaluates to zero. If the denominator is zero, the rational expression is undefined. Also there is division by zero, or related concepts in mathematics.

The nth Maclaurin polynomial for the function f(x) = -5 - x + 4x² - 5x³ + 4x⁴ + ...

The nth Maclaurin polynomial for the function f(x) = (4x − 5)/(x + 1), we need to expand the function as a power series centered at x = 0 (the Maclaurin series) and then truncate it to the desired degree.

First, let's find the Maclaurin series expansion of f(x):

f(x) = (4x − 5)/(x + 1)

To expand this as a power series, we'll use the concept of geometric series expansion. We'll start by expressing f(x) as a product of two functions:

f(x) = (4x − 5)×(x + 1)⁻¹

Now, let's find the power series expansion for each factor separately.

1.The power series expansion for (4x - 5) centered at x = 0 is given by:

(4x - 5) = -5 + 4x

2.The power series expansion for (x + 1)⁻¹ centered at x = 0 is given by the geometric series formula:

(x + 1)⁻¹ = 1 - x + x² - x³ + x⁴ - ...

Note that this expansion is valid when |x| < 1 since it's based on a geometric series.

Now, we'll multiply these two expansions together to get the expansion for f(x). We'll keep terms up to the fourth degree (n = 4).

f(x) = (4x - 5) × (x + 1)⁻¹ = (-5 + 4x) × (1 - x + x² - x³ + x⁴)

Expanding this expression:

f(x) = -5 + 4x - 5x + 4x² - 5x³ + 4x⁴ + ...

Simplifying the terms:

f(x) = -5 - x + 4x² - 5x³ + 4x⁴ + ...

This is the Maclaurin series expansion for f(x). The nth Maclaurin polynomial, we'll truncate the series at the fourth degree (n = 4):

f(x) ≈ -5 - x + 4x² - 5x³ + 4x⁴

Therefore, the fourth Maclaurin polynomial for f(x) is given by:

P₄(x) = -5 - x + 4x² - 5x³ + 4x⁴
