Answer:
<u>The mean of Jorge's scores is 119 (rounding to the next whole).</u>
Step-by-step explanation:
- 1st score = 131
- 2nd score = 110
- 3rd score = 128
- 4th score = 105
- 5th score = 120
Mean of Jorge's scores = (131 + 110 + 128 + 105+ 120)/5
Mean of Jorge's scores = 594/5
Mean of Jorge's scores = 118.8
<u>Mean of Jorge's scores = 119 (rounding to the next whole).</u>
Answer:
we know that
the relationship between the 2-dimensional polar and Cartesian coordinates is
r = √(x² + y²)
Θ = tan⁻¹ (y/x)
so
Part a) (2, −2)---------> this point belong to the IV quadrant
r = √(x² + y²)------ r = √(2² + (-2)²)-----> r=√8
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (2/2)----> 45°
remember that the point belong to the IV quadrant
so
Θ=360-45-----> Θ=315°
the answer part A) is
(r,Θ)=(√8,315°)
Part b) (-1, 3)---------> this point belong to the II quadrant
r = √(x² + y²)------ r = √(-1² + (3)²)-----> r=√10
Θ = tan⁻¹ (y/x)---- Θ = tan⁻¹ (3/1)----> 71.57°
remember that the point belong to the II quadrant
so
Θ=180-71.57-----> Θ=108.43°
the answer part B) is
(r,Θ)=(√10,108.43°)
mark me branlest plz hope it helps
Answer:
Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)
Hope this helps!!
