the business college wants to determine the proportion of business students who have extended time between classes. if the proportion differs from 30%, then the lab will modify a proposed enlargement of its facilities. suppose a hypothesis test is conducted and the test statistic is 2.5. find the p-value for a two-tailed test of hypothesis.
The business college wants to determine the proportion of business students who have extended time between classes. The p value for two tailored test was 0.0124
Let p represent the percentage of business students who own laptops.
As said, we must conduct the exam.
The test is a two-tailed test because the alternative hypothesis has two tails.
We presume that a normal distribution would apply in this situation.
We employ the z-test for proportion.
The two-tailed test's P-value is 2P(Z>|z|)=2P(Z>|2.5|).
=2P(Z>2.5)=2(1-P(Z<2.5)) P(Z>z)=1 - P(Zz)
=2(1-0.9938) Z-table, by
= 2(0.0062) (0.0062)
= 0.0124
Consequently, the two-tailed test's p-value was 0.0124.

How do you check continuity of a function?
Continuity of a function can be checked by examining the limits of the function as x approaches a certain value and ensuring the function's output is equal to the value of the function at that point.
Continuity of a function is an important concept in calculus and other branches of mathematics. In order to check the continuity of a function, the limits of the function must be examined as x approaches a certain value. This means that the left-hand limit and the right-hand limit must be equal. If the limits are equal, then the function is continuous at that point. If the limits are not equal, then the function is not continuous at that point. Additionally, the value of the function at that point must also be equal to the limits in order for the function to be continuous. If the function is discontinuous at any point, then it is not considered continuous. Continuity is necessary for certain properties of functions, such as derivatives and integrals, to be defined.

Use the summation notation to rewrite the following expression. 1 2 3 n + + + + 2! 3! 4! (n + 1)! Σ k = 1
The rewritten expression using the summation notation is ∑ k = 1 1! + 2! + 3! + ... + (n+1)!
The summation notation is a way to represent the sum of a series of terms. In the summation notation, the series of terms is represented by an expression that is followed by a summation symbol (∑). The summation symbol is usually followed by an index of the summation (k in this case), an equal sign (=), the starting value of the index, and a colon (:). The series of terms is then written below the summation symbol, with the index replacing the variable in each term.
To rewrite the given expression using the summation notation, we can use the following steps:
Identify the series of terms: 1 + 2 + 3 + ... + n.

A woman on a billboard is 8 3/8 feet tall. If the scale of the billboard is 1 foot = 8 inches, what is her actual height?
suppose the correlation between height and weight for adults is 0.40. what proportion (or percent) of the variability in weight can be explained by the relationship with height? group of answer choices 84% 16% 60% 40%
The 16% variability in weight can be explained by the relationship with height.
What is correlation?
In statistics, there are three different forms of correlation: positive, negative, and no correlation.
The link between two variables is said to be positive correlated when both variables move in the same direction. When one variable decline (or grows) while the other variable lowers (or increases), there is a positive perfect correlation, denoted by the number +1.
When two variables are correlated negatively, both of the variables are moving in the opposing direction. When one variable rises (or falls) while the other rises (or falls), there is a negative perfect correlation, which is symbolised by the number -1.
No correlation, which is represented by 0, means that there is no connection or reliance between the two variables.
On the basis of provided information, the correlation between the height and weight for adults is,
r = +0.4
So, the coefficient of determination is calculated as,
[tex]r^{2} = (0.40)^{2}[/tex] = 0.16 = 16%

Step-by-step explanation:
FIND THE FIRST DERIVATIVE OF g(x)=√x² + 2x
We are asked to find the first derivative of,
[tex]\longrightarrow g(x) = \sqrt{x^2+2x}[/tex]
Here we can write the term [tex]x^2+2x[/tex] by adding and subtracting 1 as,
[tex]x^2+2x = x^2+2x+1-1[/tex]
[tex]x^2+2x = (x+1)^2-1\quad[\because\, x^2+2x+1=(x+1)^2][/tex]
Thus,
[tex]\longrightarrow g(x) = \sqrt{(x+1)^2-1}\quad\dots(1)[/tex]
Now take,
[tex]x+1=\sec\theta\quad\dots(2)[/tex]
[tex]x=\sec\theta-1[/tex]
[tex]dx=\sec\theta\tan\theta\, d\theta[/tex]
[tex]\dfrac{d\theta}{dx}=\dfrac{1}{\sec\theta\tan\theta}\quad\dots(3)[/tex]
Then (1) becomes,
[tex]\longrightarrow g(x) = \sqrt{sec^2\theta-1}[/tex]
We have,
[tex]\sec^2\theta-1=\tan^2\theta[/tex]
So we get,
[tex]\longrightarrow g(x) = \tan\theta[/tex]
Now,
[tex]\longrightarrow g'(x) = \dfrac{d}{dx}\,[\tan\theta][/tex]
By chain rule,
[tex]\longrightarrow g'(x) = \dfrac{d}{d\theta}\,[\tan\theta]\cdot\dfrac{d\theta}{dx}[/tex]
[tex]\longrightarrow g'(x) = \sec^2\theta\cdot\dfrac{1}{\sec\theta\tan\theta}\quad\quad\textrm{[From (3)]}[/tex]
[tex]\longrightarrow g'(x) = \sec\theta\cdot\dfrac{1}{\tan\theta}[/tex]
[tex]\longrightarrow g'(x)=\dfrac{1}{\cos\theta}\cdot\dfrac{\cos\theta}{\sin\theta}[/tex]
[tex]\longrightarrow g'(x)=\dfrac{1}{\sin\theta}\quad\dots(4)[/tex]
But we have,
[tex]\sin^2\theta+\cos^2\theta=1[/tex]
[tex]\sin\theta=\sqrt{1-\cos^2\theta}[/tex]
[tex]\sin\theta=\sqrt{1-\dfrac{1}{\sec^2\theta}}[/tex]
[tex]\sin\theta=\dfrac{\sqrt{\sec^2\theta-1}}{\sec\theta}[/tex]
[tex]\sin\theta=\dfrac{\sqrt{(x+1)^2-1}}{x+1}\quad\quad\textrm{[From (2)]}[/tex]
[tex]\sin\theta=\dfrac{\sqrt{x^2+2x}}{x+1}[/tex]
Hence (4) becomes,
[tex]\longrightarrow\underline{\underline{g'(x)=\dfrac{x+1}{\sqrt{x^2+2x}}}}[/tex]
This is the first derivative of the given function.

(4x + 7y= 41
(x-7y=-16
Answer:
{ X = 5} {Y = 3} pls mark brainliest
Step-by-step explanation:
Add the two equations: 4x + 7y + (x-7y) = 41 + (-16)
Remove parentheses: 4x + 7y + x-7y = 41 + -16
Cancel one variable:4x + x + = 41 + -16
Combine like terms: 5x = 41 - 16
Calculate the sum or difference: 5x = 25
Divide both sides of the equation by the coefficient of variable: x = 25/5
Cross out the common factor: X = 5
Substitute into one of the equations: 5 - 7y = -16
Rearrange unknown terms to the left side of the equation: 5 - 7y = -16 - 5
Calculate the sum or difference: -7y = -21
Divide both sides of the equation by the coefficient of variable: -21/-7
Determine the sign for multiplication or division: y = 21/7
Cross out the common factor: y = 3
The solution of the system is: { X = 5} {Y = 3}

Define alternate exterior angle.When a transversal connects two or more parallel lines at different locations, alternate exterior angles are created. The word exterior refers to something that is located outside. Whenever the transversal intersects two lines, alternate external angles are always outside of those two lines and are situated on the opposing sides of the transversal. As a result, the pair of alternate external angles—two outside angles—that arise at the opposing ends of transversals in the exterior section are always equal. When a transversal splits two parallel lines, we obtain two of these pairs of alternate exterior angles.

Answer:m<1 = 111 degrees, m<2 = 69 degrees
Step-by-step explanation:The measure of angles 1 and 2 are supplementary, (two angles adding up to 180 degrees). Using this, set up the equation:
x + 88 + 3x = 180
4x = 108
x=23 degrees
Next, substitute 23 into the given angles:
m<1 = (23 + 88) = 111 degrees
m<2 = 23 * 3 = 69 degrees
Thus, m<1 = 111 degrees, m<2 = 69 degrees.
