Answer:
Answer: Domain is the set of all possible input for which the relation is defined. In this relation x is the variable that defines all inputs of the relation and y is the variable that defines all outputs of the relation. In the ordered pairs, the set of x-coordinates is called domain of the relation.
Step-by-step explanation:
Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3

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
