Easy not to call it 2 ones and just call it 2 instead.
a tenth is 1 divided by 10 = 0.1.
20 tenths therefore is 20 times 0.1 = 2

Answer:
Interest rate is a proportion of a loan rewarded as interest to the borrower, usually expressed as an annual percent of the current loan.
The margin of error can be calculated using the t
statistic. The formula for margin of error is given as:
<span>Margin of error = t * s / sqrt (n) ---> 1</span>
Where,
t = the t score based on the given confidence level and
degrees of freedom
n = number of samples = 21
s = standard deviation = 7.1
Degrees of freedom = n – 1 = 21 – 1 = 20
Based on the standard probability tables for t, the t
score is:
t = 0.860
Substituting into equation 1:
margin of error = 0.860 * 7.1 / sqrt (21)
margin of error = 1.33
The range is:
range = 30.1 ± 1.33
range = 28.77, 31.43
Therefore the commute time to work is between 28.77 minutes
and 31.43 minutes.
Answer:
1/2x-3=141
so first add 3 from both sides:
1/2x=141+3
1/2x=144
next divide is 1/2 on both sides
x=144/(1/2)
x=288
