The slope of the line is ___.<br> (Simplify your answer. Type an integer or a fraction.)
bonufazy [111]

Answer:

-5/7

Step-by-step explanation:

Look at the graph.  As we move from left to right from (-3, 2) to (4, -3), x increases by 7 and y decreases by 5.  Thus, the slope is

m = rise/run = -5/7.

How to remember nagative exponents how to solve nagative exponents​
marishachu [46]

To solve the negative exponents , we have to apply the negative exponent rule or the fractional exponent rule.

<h3>How are negative exponent calculated?</h3>

To calculate the negative exponent we need to remember about the negative exponent that the base is on the opposite side of the fraction. Here , We need to flip the fraction so that the base will be on the other side.

Negative exponent Rule :-

a^{-n}  = \frac{1}{a^{n} }

Now , we will solve a fraction with negative exponent

For example ; Simplify the fraction \frac{3^{-2} }{9^{-2} }

Solution : \frac{3^{-2} }{9^{-2} } =  \frac{9^{2} }{3^{2} }= \frac{81}{9}

= 9

Here, 9 is the answer of the above example.

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80. how much of the variance for the y score
enot [183]

0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

<h3>What is coefficient of determination?</h3>

The percentage of the variation in the dependent variable that can be predicted from the independent variable is known as the coefficient of determination, abbreviated R2 or r2, in statistics.

<h3>How to find the variance for the y scores?</h3>

given that

A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80.

now we have to find the variance for the y scores.

here, r=0.80 then {r}^{2}  = 0.64

which means 0.64 or 64% of the variance for the y scores is predicted by its relationship with x.

r =  \sqrt{ {r}^{2}} \: or \:  \sqrt{ {r}^{2}} \\ 0.80 =  \sqrt{ {0.80}^{2} }   \\ 0.80 = 0.80

A square has side length 10 yd. What is the length of a diagonal of the square?
Vsevolod [243]

Answer:

10√2

Step-by-step explanation:

Lets cut the square into a triangle, making a line from one corner to another, then let's see what we have.

We shoupd have a triangle where we don't know the hypotenuse, which we can find using the formula: a^2 + b^2 = c^2

so:

10^2 + 10^2 = c^2

100 + 100 = c^2

c^2 = 200

now let's square root what we got

√200

there are 2 10's in 200, which will turn the equation to:

10√2

this can't be simplified further, so our answer is 10√2
