Simplify n^4 divided by n1/2

agasfer [191]

Given:

Consider the expression is

$\dfrac{n^4}{n^{\frac{1}{2}}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\dfrac{n^4}{n^{\frac{1}{2}}}$

Using the properties of exponents, we get

$=n^{4-\frac{1}{2}}$ $\left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]$

$=n^{\frac{8-1}{2}}$

$=n^{\frac{7}{2}}$

Therefore, the simplified form of the given expression is $n^{\frac{7}{2}}$ .

What is the answer for 65=2(d+1)+5d?

vladimir1956 [14]

$65 = 2(d + 1) + 5d$
$65 = 2d + 2 + 5d$
$65 = 7d + 2$
$63 = 7d$
Finally divide by 7.
$d = 63 \div 7 = 9$
Hence, the answer is d = 9

A simple linear regression analysis was conducted to predict the Exam 3 score of students in STA 2023 based on their Exam 1 scor

Katena32 [7]

Answer:

Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.

Step-by-step explanation:

We are given the following in the equation:

A simple linear regression analysis was conducted to predict the Exam 3 score of students in STA 2023 based on their Exam 1 score.

Thus, Exam 3 score becomes the dependent variable and exam 1 score is the independent variable.

The regression equation is given by:

$\hat{y} = 50.57+0.4845x$

Comparing the equation to a linear equation:

$y = mx + c$

m = 0.4845

c = 50.57

Where m is the slope and tells the rate of change and c is the y intercept that is the value of y when x is 0.

When, there is a increase in x, we can write:

$\hat{y}(x) = 50.57+0.4845x\\\hat{y}(x+1) = 50.57+0.4845(x+1)\\\hat{y}(x+1) - \hat{y}(x) = 50.57+0.4845(x+1)-(50.57+0.4845x)\\\hat{y}(x+1) - \hat{y}(x) = 0.4845$

Thus, the slope of equation can be interpreted as:

Option A) As the Exam 1 score increases by 1 point, the student's Exam 3 grade will increase, on average, by 0.4845 points.
