Answer:
10.10% probability that in a day, there are 13 births. It is not very likely that in a day there will be exactly 13 births, but also not unlikely(lower than 5%).
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
In a recent year, a hospital had 4224 births.
An year has 365 days, so
Probability that in a day, there are 13 births.
This is P(X = 13).
10.10% probability that in a day, there are 13 births. It is not very likely that in a day there will be exactly 13 births, but also not unlikely(lower than 5%).
Answer:
the answer is B, because triangle BCA is a rotation of triangle XYZ.
Step-by-step explanation:
Answer:
y = 3
Step-by-step explanation:
4 + 3y = 6y - 5
Move all terms containing y to the left side of the equation.
4 - 3y = - 5
Move all terms not containing y to the right side of the equation.
−3y = −9
Divide each term by −3 and simplify.
y = 3

Answer:
Lateral surface area of the storage shed = 336 ft²
Step-by-step explanation:
The picture is the complete question.
The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.
lateral area of a rectangular prism = 2h (l + w)
where
l = length
h = height
w = width
h = 8 ft
l = 14 ft
w = 7 ft
lateral area of a rectangular prism = 2h (l + w)
lateral area of a rectangular prism = 2 × 8 × (14 + 7)
lateral area of a rectangular prism = 16 (21)
lateral area of a rectangular prism = 336 ft²
Lateral surface area of the storage shed = 336 ft²
