Answer: Your answer is 3.5 miles per hour.
Step-by-step explanation:
Y+1 = -2x+2 (distribute)
Y=-2x + 1 (isolate y)
The answer is
date
1 2 3 4 5 31
r1 r2 r3 r4 r5 . . . r31
1gm 2gms 3<span>gms 4gms 5gms . . . 31gms
r1+r2+ .... +r31= 31(31+1) /2=496gms (31 rings)
he only made 5 rings
31 rings----------> 496 gms
5 rings ------------> ? = 5 x496 / 31=80 gms
</span><span> the weights of those 5 rings was 80 gms</span>
There are no visible parenthasees or exponents
so pemdas
mutipcation or division whichever comes first (because division is multiplying by a fraction)
61/2
so fist is division
D is answer
You find the mean absolute deviation by first finding the mean, and then subtracting all the values in the data set from that, creating a new data set, and then you find the mean of this new data set.
Example:
3, 2, 5, 9, 4
Mean(add them all, divide by how many there are): (3 + 2 + 5 + 9 + 4)/5 = 4.6
Subtract 4.6 from/to all the values:
4.6 - 3 = 1.6
4.6 - 2 = 2.6
5 - 4.6 = 0.4
9 - 4.6 = 4.4
4.6 - 4 = 0.6
Find the mean of these values:
(1.6 + 2.6 + 0.4 + 4.4 + 0.6)/5 = 1.92
So the mean absolute deviation is 1.92.
