0.25x - 0.5y = 8 |multiply both sides by 8
2x - 4y = 64

Step-by-step explanation:
The first and third quartile of a normal distribution are:
The information provided is as follows:
Compute the first and third quartile of the wingspans as follows:
Thus, the first and third quartile of the wingspans are 116.9 cm and 133.1 cm respectively.
<span>reater than 3 tens 6 ones" probably means greater than 36, so maybe it's 37, 38, 39, and so on, up to 51. "It has more than 6 ones" probably means that it's got 7 or more in the ones place. so 40, 41, up to 46, and 50 and 51 can't be it. So we're left with 37, 38, 39, 47, 48, or 49 as possibilities for what Ava picked.</span>
Answer:
3/2
Step-by-step explanation:
y2 - y1 / x2 - x1
1 - 7 / -5 - (-1)
-6 / -4
= 3/2
(<span>4/9)/x = 12 </span>
<span>12x = 4/9 </span>
<span>x = 4 / (9•12) = 1 / (9*3) = 1/27</span>
