The angles are equal (alternate angles in parallel lines)
X + 86 = 80
X = 80 - 86 = -6
Answer:
-3/4 ÷ 2/-8 = 3 ( i think so! )
Answer:
11250
Step-by-step explanation:
Answer:
2
a) 6.37%
b) 6.25%
3
a) 0.60 %
b) 0.59 %
Step-by-step explanation:
2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %
We take the equation
<span>x^2 -4x + y^2 + 6y + 12 = 0
and complete the square for x and y.
</span><span>x^2 -4x + 4 - 4 + y^2 + 6y + 9 - 9 + 12= 0</span>
<span> (x-2)^2 - 4 + (y+3)^2 - 9 = -12</span>
<span> <span>(x-2)^2+ (y+3)^2 = 1
Therefore the answer is </span></span><span>(x-2)^2+ (y+3)^2 = 1</span>
