You can use any data set in this table (except the row with x) to get the ratio.
so 20/196 is the ratio which equals about .102041
then multiply that decimal by the weight in the x row to see what x is
so 1078(.102041) = 110.000198 just round that to 110. you can also verify that ratio by checking other data points. for instance
490(.102041) = 50.00009 or 50
so you know x is 50 so answer is either b or d
then you know the ratio .102041, so does (10/98) = .102041
or does (98/10) = .102041
if you do the division you will see that (10/98) = .102041
so the answer is D
Answer with explanation:
A: Treasury Bond: In treasury bond interest is paid till that duration until the bond completely matures. When the period of bond gets over, Actual amount or Par Amount is Returned.
⇒A Saving Instrument.
B. C D
Compact Disc. A type of device that can store data, that is Nanotechnology is used to store more than 500 MB of data.
C: Saving Account
In saving Account, you can deposit and withdraw money at any time ,any day, with the evolution of new technology.
D: Checking Account
Same with the checking account,you can withdraw and deposit money any time on a day.
→Option A, C and D are , types of account , related with currency that is money, but option B, is term related to data.
Option B: →C D is not a Saving Instrument.
The missing coordinate r is 11.
Solution:
Given points are (–15, 1) and (–7, r).
Slope (m) = 
<u>To find the missing coordinate r:</u>
Slope formula:
Substitute the given values in the formula.
Do cross multiplication.
40 = 4r – 4
Add 4 on both side of the equation.
44 = 4r
Divide by 4 on both side of the equation.
11 = r
⇒ r = 11
Hence the missing coordinate r is 11.
