Answer:
Area of the circle = 572.3 square ft.
Step-by-step explanation:
Area of a circle is given by the formula,
Area of a circle = πr²
Here 'r' = Radius of the circle
Diameter of circle given in the picture = 27 ft
Radius of the circle =
= 13.5 ft
Area of the circle = π(13.5)²
= 3.14(13.5)²
= 572.265
≈ 572.3 square ft
Using derivatives, it is found that the best estimate of f '(2) based on this table of values is of 10.
The rate of change <u>from x = 0 to x = 2</u> is given by:
From <u>x = 2 to x = 4</u>, it is given by:
The average of these rates is:
Hence, the best estimate of f '(2) based on this table of values is of 10.

The missing term is -1155.
Step-by-step explanation:
Given expression is
68 * 27 - 81 + ? = 600
Let the missing term be x
Subtracting 1755 from both sides
Therefore,
The missing term is -1155.

Answer:
The mean and the standard deviation of the number of students with laptops are 1.11 and 0.836 respectively.
Step-by-step explanation:
Let <em>X</em> = number of students who have laptops.
The probability of a student having a laptop is, P (X) = <em>p</em> = 0.37.
A random sample of <em>n</em> = 30 students is selected.
The event of a student having a laptop is independent of the other students.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The mean and standard deviation of a binomial random variable <em>X</em> are:
Compute the mean of the random variable <em>X</em> as follows:
The mean of the random variable <em>X</em> is 1.11.
Compute the standard deviation of the random variable <em>X</em> as follows:
The standard deviation of the random variable <em>X</em> is 0.836.
