x = [-3 +/- √(3^2 - 4*1*2) ] / 2
= [- 3 + √( 1)] / 2 , [- 3 - √( 1)] / 2
= -2/2 , -4/2
= [-1, -2} answer
If slope of first line is 3 and is perpendicular to second line
then second line has a slope of -1/3
Answer:
I'm not sure what you want me to answer from this, so I solved for every variable:
Angle A: 83°
Side b: 6.29
Side c: 5.8
Step-by-step explanation:
-----Angle A:
Since the sum of the interior angles of a triangle ALWAYS equal 180°, we can solve for angle A as follows:
-----Side b:
Here, we use the sin rule for finding sides, since we know all of the angles as well as one side:
-----Side c:
4 : 28 is the same as 4/28
4/28 = 1/7
The answer is C
Answer:
B. False
Step-by-step explanation:
We have that both studies have the same production for what the first part of the statement mentions.
"A repeated-measures study and an independent-measures study both produces a t statistic with df = 20"
And they ask us if it is false or true, if one produces more than the other.
Starting from the first statement, the second statement is false because they produce the same, therefore they will be the same subjects.
