Answer: The mass of each passenger is 550 kg.
The mass of front decoration = 200 Kg.
Step-by-step explanation:
Let the mass of each passenger be 'x'.
Let the mass of front decoration be 'y'.
So, Number of passenger = 6
Mass of 6 passengers and front decoration = 3500 kg.
Number of passengers = 4
Mass of 4 passengers and front decoration = 2400 kg.
According to question, it becomes,
so, From Eq(1) and Eq(2), we have,
Hence, the mass of each passenger is 550 kg.
The mass of front decoration = 3500-550(6)=200 Kg.
Answer:
Hello a value is missing in your question below is the value
samples of n = 10
answer : 24.63 < μ < 25.370
Step-by-step explanation:
Given :
Sample size = n = 10
Z∝/2 = Z0.0256 = 1.95
next calculate for margin of error
E = Z∝/2 * ( 0.6 / / )
= 0.370
therefore at 94.87% confidence interval the estimated population mean is
x - 0.370 < μ < x + 0.370
25 - 0.370 < μ < 25 + 0.370
24.63 < μ < 25.370
