Answer:
<em>Another way to calculate the correlation coefficient </em><em>(r) </em><em>is to </em><u><em>multiply</em></u><em> the slope of the regression line by the </em><u><em>standard deviation</em></u><em> of </em><em>X</em><em> and then </em><u><em>divide</em></u><em> by the standard deviation of </em><em>Y</em><em>.</em>

Answer:
5. m26+m27+m28= m81
Step-by-step explanation:
because 26+27 =53 and you just plug in m
and 28+53 = 81
Answer:
10.89
Step-by-step explanation:
The hundredth place is the second decimal value. Remember that 4 and below round down and 5 and above, round up.
10.89249 -> 10.89
Best of Luck!
Answer:
3/20
Step-by-step explanation:
This is a division question.
The equation is 3/4 ÷ 5 or, to simplify this, 3/4 ÷ 5/1.
When you divide fractions you have to flip the second number and multiply the two fractions.
So, you have to do 3/4 x 1/5 which is 3/20.
Thus, the answer is 3/20.
Good luck!
For number 11 the third angle would be equal X as the second angle is, since the two sides next to the those angles are congruent. Then you would have to set an equation saying that 2x + 38= 180 and then you can just solve for X
