The base value is the current value
Good luck! I hope this helps!
Answer:
Answer is in attached picture
Step-by-step explanation:
There are no real solutions for the value of 'x'. The two solutions are complex. The fully simplifed answers would be:
x = 4 + 5i*sqrt(7)
x = 4 - 5i*sqrt(7)
Answer:
The length of DF is 15
Step-by-step explanation:
Since the two lines are equal, which is given by the markings on the triangle, then you can set the two lengths equal and find x.
7x - 13 = 3x + 3
4x - 13 = 3
4x = 16
x = 4
Now that we know x = 4, we can plug into the DF length to find its amount.
DF = 7x - 13
DF = 7(4) - 13
DF = 28 - 13
DF = 15
Answer:
Explanation:
The <em>possible values of r</em>, the correlation coefficient of a sequence of values, are -1 ≤ r ≤ 1.
This is, r cannot be either less than - 1 or greater than 1.
A correlation coefficient r = -0.1 denotes a very weak negative correlation. A correlation coefficient r = - 0.75 means a strong negative correlation. A correlation coefficient r = 0.5 indicates a moderate positive correlation. A value of r = 1.2 is not possible: r can neve be greater than 1.
