Answer:
Step-by-step explanation:
we know that
![\°C=\frac{5}{9}[\°F-32]](https://tex.z-dn.net/?f=%5C%C2%B0C%3D%5Cfrac%7B5%7D%7B9%7D%5B%5C%C2%B0F-32%5D)
For 
substitute in the formula and solve for F
![94=\frac{5}{9}[F-32]](https://tex.z-dn.net/?f=94%3D%5Cfrac%7B5%7D%7B9%7D%5BF-32%5D)
![(\frac{9}{5})*94=[F-32]](https://tex.z-dn.net/?f=%28%5Cfrac%7B9%7D%7B5%7D%29%2A94%3D%5BF-32%5D)
Answer : 6x^5 + 6x^2 - 5
Combine the like terms :
4x^5 + 2x^5 = 6x^5
3x^2 + 3x^2 = 6x^2
-6 + 1 = -5
Put into descending order.
Answer:
7.92 m.
Step-by-step explanation:
Mean height = ∑(f . x) / ∑f where x is the midpoint and f the frequencies
The midpoints for the heights are:
2 for frequency 8 ( 0 + 4)/ 2 = 2
6 for .. 21
10 for .. 12
14 for .. 7
18 for .. 2
So the mean is:
[(2*8) + (6*21) + (10*12) + (14*7) + (18*2) ] / (8 + 21+12+7+2)
= 396 / 50
= 7.92 m.
The correct order would be:
5/64 x 3, 1/16 x 3, 3/32 x 4, 11/64 x 4, 7/16 x 3, 3/4 x 2, 3/8 x 4, 1 7/8 x 4, 2.25 x 2, 1.5 x 4, 3 3/8 x 3, 3.75 x 3
First we have to take all of the numbers and do the multiplication. It's often easiest to turn them in to decimals so that you have a common form.
3/32 x 4 = 3/8 = .375
3/4 x 2 = 3/2 = 1.5
1 7/8 x 4 = 15/4 = 3.75
2.25 x 2 = 4.5
1.5 x 4 = 6
3/8 x 4 = 3/2 = 1.5
5/64 x 3 = 5/32 = .156
3.75 x 3 = 11.25
1/16 x 3 = 3/16 = .1875
7/16 x 3 = 21/16 = 1.31
3 3/8 x 3 = 81/8 = 10.125
11/64 x 4 = 11/16 = .687
Now we can use those to put in order.
5/64 x 3 = 5/32 = .156
1/16 x 3 = 3/16 = .1875
3/32 x 4 = 3/8 = .375
11/64 x 4 = 11/16 = .687
7/16 x 3 = 21/16 = 1.31
3/4 x 2 = 3/2 = 1.5
3/8 x 4 = 3/2 = 1.5
1 7/8 x 4 = 15/4 = 3.75
2.25 x 2 = 4.5
1.5 x 4 = 6
3 3/8 x 3 = 81/8 = 10.125
3.75 x 3 = 11.25
Which if you are looking for without the extra terms, you can check the answer at the top.
the answer would be 8.
2 times 8 = 16 minus 5 = 11
