Note that the correlation coeff. must have a value between -1 and +1. If r is very close to 1, then there is a strong positive correlation; if very close to -1, then there is a very strong negative correlation. Thus, if r = -0.925, we have a "strong negative" correlation.
Please, next time, separate your possible answer list with commas or put only one possible answer on each line.
Answer:
2x + 6
Step-by-step explanation:
You multiply 2 by the numbers in parentheses. 2 times x is 2x, and 2 times 3 is 6.
To solve for X you need to simplify both sides on the equation
<span><span><span>23</span><span>(<span><span>4x</span>−5</span>)</span></span>=8
</span><span><span><span><span>(<span>23</span>)</span><span>(<span>4x</span>)</span></span>+<span><span>(<span>23</span>)</span><span>(<span>−5</span>)</span></span></span>=8 *</span>Distribute*
<span><span><span><span>8/3</span>x</span>+<span><span>−10/</span>3</span></span>=<span>8
after that you add 10/3 on both sides
</span></span><span><span><span><span><span>8/3</span>x</span>+<span><span>−10/</span>3</span></span>+10/3</span>=<span>8+10/3</span></span><span><span><span>8/3</span>x</span>=<span>34/<span>3
finally multiply 3/8 on both sides
</span></span></span><span><span>(<span>3/8</span>) x </span><span>(<span><span>8/3</span>x</span>)</span></span>=<span><span>(<span>3/8</span>) x </span><span>(<span>34/3</span><span>)
and your answer should be
X= 17/4
