<span>So, they are looking for the percentage that is NOT explained...
Well, given the r we can find the percentage that IS explained by it first. That's given by r^2.
</span>Now - let's take the square of r it gives me .481636. That means that about 48% IS explained. Therefore, the part that cannot be explained
must be the missing part (out of 100% <span>so
100% - 48.1636% should be it :)
</span>
<span>So 100% - 48.1636% = 0.518364 and we want to round that off to three decimal places which will give us 0.518... and then we could convert that to a percent for the final. So 0.518 as a percentage is 51.8%! s</span>
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
Answer:
(d) (4x² +7)(x -3)
Step-by-step explanation:
This polynomial can be factored by factoring pairs of terms.
= (4x³ -12x²) +(7x -21)
= 4x²(x -3) +7(x -3)
= (4x² +7)(x -3)

<em>Additional comment</em>
The answer choices suggest we're not interested in irrational or complex factors. The quadratic (4x² +7) could be factored into linear terms involving irrational complex numbers. The form for "difference of squares" would be used for the purpose.
(82,82,) (x+y) answer short
Answer:
Step-by-step explanation:
c + f = 16......c = 16 - f
340c + 910f = 9430
340(16 - f) + 910f = 9430
5440 - 340f + 910f = 9430
-340f + 910f = 9430 - 5440
570f = 3990
f = 3990/570
f = 7 <====== 7 first class tickets bought
c + f = 16
c + 7 = 16
c = 16 - 7
c = 9 <====== 9 coach tickets bought
