Answer:
Trapezoid
Step-by-step explanation:
To find the shape of the quadrilateral given by the coordinates, we have to find the length of the sides first. The length between two side O(x1, y1) and P(x2, y2) is given as:
Therefore the length of the sides are:
Since all the sides are not equal, it is a trapezoid. In a trapezoid all the sides must not be equal
As there is a 50% chance the child is a girl (G), we can multiply by 50% to get the probability of selecting a boy (B) if the newborn is a girl
With a mean of λ , the probability mass distribution (pmf) is given by
for λ = 4, and k<2 (i.e. k=0 or 1)
P(k<2, λ )=P(k=1, λ ) + P(k=1, λ )
=0.01832+0.07326
=0.09158 (to the fifth place of decimal)
Note: Poisson processes have no memory, so 2 calls in first hour has the same probability as 2 calls in any other hour.

Answer:
21.186%
Step-by-step explanation:
z = (x-μ)/σ,
where
x is the raw score = 2400mg
μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
z = 2400 - 2000/500
z = 0.8
Probability value from Z-Table:
P(x<2400) = 0.78814
P(x>2400) = 1 - P(x<2400) = 0.21186
Converting to percentage:
0.21186 × 100
= 21.186%
Therefore, the percent of the meals
ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%
