$a_n=a_1.r^{n-1}\\
\\
a_{10}=(0.2).5^9\\
\\
a_{10}=(0.2).1,953,125=390,625$

Find the equation to the line below.

ZanzabumX [31]

Answer:

$y = \frac{4}{5}x - 1$

Step-by-step explanation:

Every time the line moves 5 units to the right, it moves up 4 units as well. Since the slope is the difference in y divided by the difference in x, the slope is 4/5. In addition, the y-intercept is -1. Therefore, the equation of this line is $y = \frac{4}{5}x - 1$ .

The greater of is 7 more than the lesser. three times the greater number is 5 more than r4 times the lesser number. Find the num

Ilya [14]

<h2>Steps:</h2>

(Let x = greater number and y = lesser number)

So this question is asking us for a system of equations. Using the info they provide, we can form these two equations:

$x=y+7\ \textsf{("The greater of the numbers is 7 more than the lesser.")}\\3x=4y+5\ \textsf{("Three times the greater number is 5 more than 4 times the lesser number.")}$

So for this, we will be using the substitution method. Since we know that x = y + 7, substitute x with (y + 7) in the second equation as such:

$3(y+7)=4y+5$

From here we can solve for y. Firstly, distribute 3 so that it multiplies with y and 7:

$3y+21=4y+5$

Next, subtract 3y on both sides of the equation:

$21=y+5$

Lastly, subtract 5 on both sides of the equation:

$16=y$

Now that we know the value of y, we can substitute it into either equation to solve for x:

$x=16+7\\x=23\\\\3x=4(16)+5\\3x=64+5\\3x=69\\x=23$

<h2>Answer:</h2>

<u>In short, 16 is the lesser number and 23 is the greater number.</u>

A larger error variance makes it difficult to estimate the partial effect of any of the independent variables on the dependent v

mel-nik [20]

A larger error variance making it difficult to estimate the partial effect of any of the independent variables on the dependent variable is True.

<h3>What is Variance?</h3>

This is used to measure how far a data is spread out and the effect independent variables has on the dependent ones.

When there is an error in the variance, the effect calculated is inaccurate which brings about difficulty in ascertaining it.
