180 - 130 = 50°
opposite sides add up to 180
Answer:
15(1/3b+3)≤6(b+9)
3b+3×15(1/3b+3)≤3b+3×6(b+9)
15≤3b+18(b+9)
15≤3b+18(b+9)
15≤21b+162
162-15≤216
147≤216
147/21≤b
7≤b
b≤7
<span>x − 3y = −2
x + 3y = 16
----------------add
2x = 14
x = 7
</span>x − 3y = −2
7 − 3y = −2
<span>-3y = -2 -7
-3y = -9
y = 3
so x = 7 and y = 3
answer is </span><span>A) (7, 3)</span>
(1/2,3)(2,3/4)
slope = (3/4 - 3) / (2 - 1/2) = (3/4 - 12/4) / (4/2 - 1/2) =
(-9/4) / (3/2) = -9/4 * 2/3 = -18/12 = -3/2
Answer:
1485 are likely to be infected.
Based on the sample, the probability of an elk being infected is 11/50. Multiply this by the number of elk:
11/50(6750) = 1485.
