Answer:

7.1 feet^2

Step-by-step explanation:

The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:

area = π * r^2

area = 3.14 * (3/2 feet)^2

area = 7.065 feet^2 = 7.1 feet^2

What expression is equivalent to (4y^2-3) (4y+3)

Naya [18.7K]

Answer:

Step-by-step explanation:

Just use the distributive property.

(4y^2-3)(4y+3)

= 4y^2(4y+3) - 3(4y+3)

= 16y^3 + 12y^2 - 12y - 9

Find the probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 b

jeka94

Answer:

Step-by-step explanation:

From the given information; Let's assume that R should represent the set of all possible outcomes generated from a bit string of length 10 .

So; as each place is fitted with either 0 or 1

$\mathbf{|R|= 2^{10}}$

Similarly; the event E signifies the randomly generated bit string of length 10 does not contain a 0

Now;

if a 0 bit and a 1 bit are equally likely

The probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely is;

$\mathbf{P(E) = \dfrac{|E|}{|R|}}$
