Just plug in 4 for the x
2*4 +4y =36
8+4y =36
4y =36-8
4y=28
y= 28/4
y=7
The answer should be 4.3 (the line is ontop of the 3)
The line is on the 3

Answer:
- perimeter: 22 1/30 m
- area: 29 m²
Step-by-step explanation:
The perimeter is given by the formula ...
P = 2(L+W)
P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)
P = 22 1/30 . . . . meters
__
The area is given by the formula ...
A = LW
A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters
The perimeter is 22 1/30 meters; the area is 29 square meters.
Answer: 0.6521
Step-by-step explanation:
According to the Binomial distribution , the provability of getting x successes in n trials is given by :-
, where p=probability of getting success in each trial.
Let x denotes the number of defective products.
here , n=7 and p =0.14
Then, the probability that among 7 randomly selected products, at least one of them is defective= P(X ≥ 1) =1- P(X<1)
= 1- P(X=0)

![=1-(1(1)(0.86)^7\ \[\because ^nC_0=1]](https://tex.z-dn.net/?f=%3D1-%281%281%29%280.86%29%5E7%5C%20%5C%5B%5Cbecause%20%5EnC_0%3D1%5D)


Hence, the probability that among 7 randomly selected products, at least one of them is defective is 0.6521 .
