We know that
The MAD is <span>the mean absolute deviation of the data
step 1
</span><span>To find the mean absolute deviation of the data, start by finding the mean of the data set.
</span><span>Find the sum of the data values, and divide the sum by the number of data values
</span>sum of the data values=[130+150+190+100+175+120+165+140+180+190]
sum of the data values=1540
number of data=10
Mean=1540/10-----> 154
step 2
<span>Find the absolute value of the difference between each data value and the mean: |data value – mean|.
</span> |130 – 154|=24
|150 – 154|=4
|190 – 154|=44
|100 – 154|=54
|175 – 154|=21
|120 – 154|=34
|165 – 154|=11
|140 – 154|=14
|180 – 154|=26
|190 – 154|=44
step 3
<span>Find the sum of the absolute values of the differences.
</span>=[24+4+44+54+21+34+11+14+26+44]------> 276
step 4
<span>Divide the sum of the absolute values of the differences by the number of data values.
</span>276/10-----> 27.6
the answer is
27.6
Answer:
4
Step-by-step explanation:
it's just another way of saying find the slope
If the company performs badly, or there's a perception it does so, then the stock's value will go down and you'll lose money. The only way to earn money from stocks is if the company is able to be innovative and survive the competition. The worst case scenario is that you lose all your money if the company goes bankrupt.
To reduce the risk, you should diversify your investments so that you invest in multiple companies along multiple sectors of the economy. This spreads out the risk so that if one company fails, then its unlikely they all fail (assuming there isn't some catastrophic event in the market). Alternatively, you can invest with mutual funds or index funds to let other people/entities invest your money with a range of diverse companies.
Answer:
G(2b) = 10b + 3
Step-by-step explanation:
To find G(2b), simply plug in 2b wherever there is an x in G(x).
G(x) = 5x + 3
G(2b) = 5(2b) + 3
G(2b) = 10b + 3
