Answer:
Seat belts have been keeping us more safe than without them. They have been keeping us safe and preventing us from the major effects of a car crash. Of course people die but people get a little less of the damage like your head banging into the steering wheel or flying out the front window from the back image. For some smart cars, when it stops it holds the seat belt back from moving in order to protect you.

Answer:
Th value of u is 1.6
Step-by-step explanation:
In order to find the value of u, you have to multioly both sides by 7 :
![\frac{u}{7} = \frac{3}{13}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bu%7D%7B7%7D%20%20%3D%20%20%5Cfrac%7B3%7D%7B13%7D%20)
![\frac{u}{7} \times 7 = \frac{3}{13} \times 7](https://tex.z-dn.net/?f=%20%5Cfrac%7Bu%7D%7B7%7D%20%20%5Ctimes%207%20%3D%20%20%5Cfrac%7B3%7D%7B13%7D%20%20%5Ctimes%207)
![u = 1.6 \: (near. \: tenth)](https://tex.z-dn.net/?f=u%20%3D%201.6%20%5C%3A%20%28near.%20%5C%3A%20tenth%29)
To answer this, we will look at simple definitions of each term. From the definitions, it will be clear which one is correct.
<u>What is mode?</u>
It is the most occurring number.
<u>What is interquartile range?</u>
It is the difference between third quartile and first quartile.
<u>What is range?</u>
It is largest number minus the smallest number.
<u>What is mean absolute deviation (MAD)?</u>
It is the average distance of each data point from the mean.
<u>What is a quartile?</u>
It is one of the four groups in which a dataset is divided.
From the simple definitions of each term, we can clearly see that Mean Absolute Deviation (MAD), answer choice D, is the correct answer.
Answer: Mean Absolute Deviation
Answer:
137
Step-by-step explanation:
given AP
t1 = -3 and t2 = 4
using,
d=t1-t2
=4-(-3)
=7
And,
tn=a+(n-1)d
t21=(-3)+(21-1)(7)
t21=137
