Answer:
the probability of no defects in 10 feet of steel = 0.1353
Step-by-step explanation:
GIven that:
A roll of steel is manufactured on a processing line. The anticipated number of defects in a 10-foot segment of this roll is two.
Let consider β to be the average value for defecting
So;
β = 2
Assuming Y to be the random variable which signifies the anticipated number of defects in a 10-foot segment of this roll.
Thus, y follows a poisson distribution as number of defect is infinite with the average value of β = 2
i.e

the probability mass function can be represented as follows:

where;
y = 0,1,2,3 ...
Hence, the probability of no defects in 10 feet of steel
y = 0


P(y =0) = 0.1353
220
from 218 the 1 is in the tens column. this is the figure that needs to be rounded.
using the following rule
If the digit after the 1 is ≥ 5 then round 1 up to 2
If the digit after the 1 is < 5 then the 1 remains as 1
here the digit after the 1 is 8 so the 1 in the ten's column becomes 2 and the 8 is replaced by 0
218 ≈ 220 ( to the nearest ten )
<span>To explain how these values are related, take the second value (625) and multiply it by 1/100, or in decimal form, 0.01. This is the equivalent of moving the decimal point two spaces to the left, which will give a result of 6.25. (625 * 0.01 = 6.25). This shows that the two values are 100 times different than each other.</span>
Answer:
$80.00
Step-by-step explanation:
We have: 120 ft = 40 yards (divide the length value by 3
)
=> Jerome will cost: 40 x $2.00 = $80.00 for the fencing.
