Answer:

7.96 *10^8kg

Step-by-step explanation:

Given

Eiffel = 9.16 * 10^6\ kg

Golden\ Gate =8.05 * 10^8kg

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

Difference = Golden\ Gate - Eiffel

Difference = 8.05 * 10^8 - 9.16 * 10^6

Express 10^8 as 10^6 * 10^2

Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6

Express 10^2 as 100

Difference = 8.05 * 100*10^6 - 9.16 * 10^6

Difference = 805 *10^6 - 9.16 * 10^6

Factorize:

Difference = (805- 9.16) * 10^6

Difference = 795.84 * 10^6

Factorize the decimal number

Difference = 7.9584 *10^2 * 10^6

Difference = 7.9584 *10^8

Approximate:

Difference = 7.96 *10^8

Assuming a normal distribution  we find the standardized z scores for  a:-

z1 = (80 - 180)  / 25  =  = -100/25  = -4
z2 =  (280-180) / 25  =  4
Required P( -4 < z < 4)  from the tables is  >99.9%

b
z1 = 130-180 / 25 =  -2
z2 =  230-180 / 25  = 2

from tables probability is 2* 0.4773  =  95.46 %
