Answer:80 percent
Step-by-step explanation:
From the question, the total number of sample is 100 that is hundred(100) people . Eighty (80) people from the sample are in favour of candidate A.
Therefore, the mean statistic is one(1), that is, 0.8+0.05+1.15+2.00= 1.
So, total number from the hundred people supporting Candidate A divided by the total number of sample of the population multiply by a 100 percent;
= 80/100 × 100= 80%.
80% which is greater than 75%
10.
a) x- is the time after which the total cost is the same.
24 + 99x - is the cost in the dealership
45 + 89x is the cost at the local mechanic
24 +99x = 45 + 89x
99x - 89x = 45 - 24
10x = 21
x= 2.1 (hours)
b) 24 +99x < 45 + 89x
x< 2.1
The repairs cost less in dealership when work takes less than 2.1, and the dealership is better, because the cost of parts is less in the dealership.
Answer: Option A
Step-by-step explanation:
Answer:
21.5%
Step-by-step explanation:
volume of cube: 36x36x36
volume of cylinder: πx18²x36
Cylinder percentage: (πx18²x36) / 36x36x36 = π / 4 = 0.785
percentage of empty space: 1 - 0.785 = 0.215 (21.5%)
