Answer:
Percentage error is 0.0024 %
Step-by-step explanation:
Initial average distance between Earth and moon = 384467 km
Distance measure by the scientist = 384476 km
Total variation in the distance calculation = 384476 – 384467 = 9 km.
Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.
Percentage error = ( 9 / 384467 ) × 100 = 0.0024 %
Answer:
y=3x-21
Step-by-step explanation:
a line is parallel if the slopes of the lines are the same
so that means that out line should look something like this
y=3x+b
then, we use our point given to find b
-3=18+b
b=-21
the equation of out line is y=3x-21
Answer:
Step-by-step explanation:
There are a total of 10 persons (6 teachers + 4 students) from which a committee of 5 is to be formed. This can be done in 10C5 ways.
The number of ways that a committee can be formed with no students in it is to select 5 teachers out of the pool of 6 teachers available. This can be done in 6C5 ways.
Therefore the total number of ways that the committee can be formed with at least one student in it is 10C5 - 6C5.
10C5 = 252
6C5 = 6
Therefore the required number of ways = 246
Answer:
12,500-11,625=875
875/12,500=7/100
7/100*100=7
The percentage reduction is 7%

The price elasticity of demand is the change in quantity demanded relative to the change in price.
- <em>The second figure in the attached image represents the revenue graph</em>
- <em>The price elasticity of demand is 0.143</em>
- <em>The demand must be inelastic</em>
Let:
<u>(a) The total revenue</u>
From the first graph (see attachment), we have:
The total revenue (T) is calculated using:
So, we have:
<em>The second figure in the attached image represents the revenue graph</em>
<u>(b) Price elasticity of demand</u>
Between points A and B, we have:
The price elasticity of demand is:
So, we have:
<em>The price elasticity of demand between points A and B is 0.143, and the demand must be inelastic because an increase in price of the bike leads to a decrease in the total revenue</em>
