F(-4) = 0
Here, we replace x with -4. In doing so, we see that (-4+4) is indeed 0, making this the correct answer.
The next two choices are incorrect since only -4 is a root of f(x), as explained above (a root occurs when the function equals zero when plugging in that “root”).
The last answer is incorrect since plugging in 4 will get f(4)=8.
8 2/3 = (3 * 8 + 2)/3 = 26/3

The volume of the cylinder and the cone is equal
<h3>Volume of a cylinder and a cone</h3>
The formula for calculating the volume of a cylinder is expressed as:
V = πr²h
where
r is the radius
h is the height
For the cylinder
r = 8/2 = 4 in
h = 5
Substitute
V = π(4)²*5
V = 80π cubic inches
For the cone
r = 4 in
h = 15in
Substitute
V = 1/3πr^2h
V = 1/3(π)(4)^2 * 15
V = 80π cubic inches
Hence the volume of the cylinder and the cone is equal

#SPJ1
Answer:
a) 0.0255
b) 0.7050
c) 0.2945
Step-by-step explanation:
Probability that one of those sampled saying that Roosevelt was the best president since World War II = 330/2062 = 0.16
Probability that one of those sampled don't mention Roosevelt = (2062 - 330)/2062 = 1732/2062 = 0.84
a) The probability that both adults picked say Franklin Roosevelt was the best president since World War II = (330/2062) × (329/2061) = 0.0255
b) The probability that neither of the two adults say Franklin Roosevelt was the best president since World War II = (1732/2062) × (1731/2061) = 0.7050
c) The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = Probability that one of the two adults mention Roosevelt + Probability that the two adults mention Roosevelt
Probability that one of the adults mention Roosevelt = [(330/2062) × (1732/2061)] + [(1732/2062) × (330/2061)] = 0.269
Probability that two of the adults mention Roosevelt has been done in (a) and it is equal to 0.0255
probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II = 0.269 + 0.0255 = 0.2945
Yes! That is correct!
