Answer:
5/6
Step-by-step explanation:
1/2 + 1/3 need a common denominator to add them up.
1/2 is the same as 3/6.
1/3 is the sane as 2/6.
3/6 + 2/6
Add the tops, but keep the same denominator.
3/6 + 2/6 = 5/6
5/6 cannot be simplified, so that's the answer. That's how you do it! Hope this helps!
Answer:
I have made it in above figure
Answer:
Option B.
Step-by-step explanation:
In a regression of y in x, the proportion oh the variation in y explained by the variable x is shown in the R-squared value. So, for answering this question we need to look at the R-squared of such regression.
In this case the R-squared is 98.9% (or 0.989), so we will the option that matches this value. Looking at your options, the one that matches the R-squared is option B.
So, B is the correct option.
Answer: 24.2° SouthWest
<u>Step-by-step explanation:</u>
First step: DRAW A PICTURE of the vectors from head to tail <em>(see image)</em>
I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.
<u>Perpendicular (x):</u>
cos 35° = adjacent/hypotenuse
cos 35° = x/160
→ x = 160 cos 35°
<u>Angle (θ):</u>
sin θ = opposite/hypotenuse
sin θ = x/320
sin θ = 160 cos 35°/320
θ = arcsin (160 cos 35°/320)
θ = 24.2°
Direction is down (south) and left (west)
Answer:
2) (3,-2)
Step-by-step explanation:
the solution is where the lines intersect. they intersect at one point because this function is linear. they intersect at the point (3,-2)
