Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The low yield rate is
The sample size n = 80
Hence the probability that the bottle is bad
=>
=>
Generally the distribution of yield follows a binomial distribution
i.e
and the probability distribution function for binomial distribution is
Here C stands for combination hence we are going to be making use of the combination function in our calculators
Generally the probability less than three bottles are bad is mathematically represented as
=>
=>
=>
Answer:
y=5x+2/3
Step-by-step explanation:
if y is negative you put that first equaling -5x because you are subtracting -2/3
seeing as the y has to be positive in the equation therefore you must multiply the whole equation by a negative in order to get the y to be postitive.

Answer:
a) $540 cost to paint
b) 72000 liters to fill
Step-by-step explanation:
Relevant formulas are ...
P = 2(L +W) . . . . perimeter of a rectangle of length L and width W
A = LW . . . . . . area of a rectangle of length L and width W
V = LWH . . . volume of a cuboid of length L, width W, and height H
__
a) The total painted area is the area of the pool walls plus the area of the pool bottom. The wall area is the product of pool perimeter and wall height. The bottom area is the product of pool length and width.
A = PH + LW = 2(L +W)H +LW
A = 2(8 m +6 m)(1.5 m) + (8 m)(6 m) = 42 m² +48 m² = 90 m²
At $6 per square meter, the cost of painting the pool is ...
($6 /m²)(90 m²) = $540 . . . . cost to paint the pool
__
b) The volume in liters is best figured using the dimensions in decimeters.
V = (80 dm)(60 dm)(15 dm) = 72000 dm³ = 72000 L
72000 liters will be needed to fill the pool.
Let the "population of linton" be represented by the letter L
and the "popluation of ellmore" be represented by the letter E
L = 12E
L + E = 9646
are the two equations we can get from the given information
plugging in L = 12E into the second equation we can get:
12E + E = 9646 [now solve for E]
13E = 9646 [added like terms]
E = 742 [divided 13 from both sides]
then plug this back into the first equation and get:
L = 12*(742) = 8904
Therefore the Population of Linton is 8904 people.
