Answer:
95%
Step-by-step explanation:
Total distance of trip = 980 miles
Miles covered when Amelia slept = 931 miles
what percentage of the total trip had they travelled when Amelia fell asleep?
Miles yet to be covered = 980 miles - 931 miles
= 49 miles
percentage of the total trip had they travelled when Amelia fell asleep = 931 / 980 × 100
= 0.95 * 100
= 95%

Answer:
Nominal
Step-by-step explanation:
Data can be divided into 2 types:
- Qualitative Data
- Quantitative Data
Qualitative data represent some attribute or characteristic and cannot be measured or calculated. This type of data uses Nominal or Ordinal level of measurement.
Quantitative data is the data which can be measure or calculated. This type of data is expressed in Ratio or Interval scale.
Different genres of music represent an attribute, hence the data is Qualitative. Qualitative data which can put into some order is at Ordinal scale of measurement, while if the data simply represent the name or attributes it would be at Nominal Level.
Different genres of music cannot be put into some order and are just names, hence the measurement scale would be Nominal.
Answer:
5%
Step-by-step explanation:
The equation for simple interest rate is as follows:
A = P(1+rt)
A = final amount
P = initial principal amount
r = annual interest rate
t = time (in years)
So, we need to plug everything in and solve for r:
The final amount is equal to $875 plus the interest of $131.50.
A = 875 + 131.50 = 1006.50
Now, plug everything in:
1006.50 = 875( 1 + r(3))
Solve:
1 + 3r = 1.15028571 Divide 1006.50 by 875
3r = 0.15028571 Subtract 1 from 1.15028571
r = 0.050 Divide by 3
The simple interest rate would be 5%. I converted the r to a percent by multiplying 0.050 by 100.
