Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11

Answer:
j
Step-by-step explanation:
Answer:
<u><em>8/20</em></u>
Step-by-step explanation
<em>boys left handed=3
</em>
<em>boys right handed=9
</em>
<em>girls left handed=2
</em>
<em>girls right handed=6
</em>
<em>what is the probability that a student chosen from random is a girl? give answer as a fraction please and include step by step process</em>
<em>girls left handed: 2</em>
girls right handed: 6
6+2=8
total all students 20
<em>8/20</em>
The solution would be like
this for this specific problem:
<span>V = ∫ dV </span><span>
<span>= ∫0→2 ∫
0→π/2 ∫ 0→ 2·r·sin(φ) [ r ] dzdφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ r·2·r·sin(φ) - r·0 ] dφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ 2·r²·sin(φ) ] dφdr </span>
<span>= ∫0→2 [
-2·r²·cos(π/2) + 2·r²·cos(0) ] dr </span>
<span>= ∫0→2 [
2·r² ] dr </span>
<span>=
(2/3)·2³ - (2/3)·0³ </span>
<span>= 16/3 </span></span>
So the volume of the
given solid is 16/3. I am hoping that these answers have satisfied
your query and it will be able to help you in your endeavors, and if you would
