Imaginary, you cannot form the square root of a negative #
Can u clarify more please
Answer:
25πm²
Step-by-step explanation:
Circumference of the circular sculpture = πd
d is the diameter
Given
Circumference = 10π metres
Substitute into the formula
10π = πd
10 = d
d = 10m
Area of the sculpture = πd²/4
area of the sculpture = π(10)²/4
area of the sculpture = 100π/4
area of the sculpture = 25π m²
Hence the measurement closest to the area of the sculpture in square meters is 25πm²
Answer:
Probability that an ear of corn selected at random will contain no borers is 0.4966.
Step-by-step explanation:
We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.
Let X = <u><em>Number of borers per ear</em></u>
The probability distribution of the Poisson distribution is given by;
where,
= parameter of this distribution and in our question it is proportion of bores in the total ears =
= 0.7
SO, X ~ Poisson(
= 0.7)
Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)
P(X = 0) =
=
= <u>0.4966</u>
Hence, the required probability is 0.4966.
