Answer:

The scatter diagram that contains the correlation coefficient closest to r = 1 is the first one shown in the attached images.

Step-by-step explanation:

The correlation coefficient "r" measures how much two variables x and y are related. When the variables are highly related, the value of r is closer to one and the points contained in the scatter diagrams are assimilated more and more to a line. When the value of r is positive the relation is crescent and therefore the slope of the line drawn by the points in the diagram has a positive slope


Therefore, to answer this question, one must search among the attached images for the dispersion diagram in which the points resemble a straight line with a positive slope.


The scatter diagram that meets the requirements mentioned is the first one that appears in the attached images

Help!! Dont know how to do this!
CaHeK987 [17]

Answer:

A=(5D-5h)/4

Step-by-step explanation:

So you need to get <em>a</em> on one side so you subtract <em>h</em> on both sides to eliminate the <em>h</em> on the right side: <em>D-h=4/5 a</em>

now you need to multiply 5/4 on both sides in order to make 4/5 <em>a</em> just <em>a</em>

A=(5D-5h)/4

Hope this helps!

(2x+1)/2=(x+2)/5<br><br>if possible can you show me step by step how to get the answer <br>​
katrin2010 [14]

Answer:

\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}

\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}

Step By Step Explanation:

Apply Fraction Cross Multiply: If \bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}

\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}

\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}

\bold{2\left(x+2\right): \ 2x+4}

\bold{10x+5=2x+4}

Subtract 4 From Both Sides

\bold{10x+5-5=2x+4-5}

Simplify

\bold{10x=2x-1}

Subtract 2x From Both Sides

\bold{10x-2x=2x-1-2x}

Simplify

\bold{8x=-1}

Divide Both Sides By 8

\bold{\frac{8x}{8}=\frac{-1}{8}}

Simplify

\bold{x=-\frac{1}{8}}

Turn Fraction Into Decimal

\bold{-1 \ \div \ 8 \ = \ -0.125}

\bold{-0.125}
