Find the radius of a sphere with a surface area of $4\pi$ square feet.

Mathematics

Answer:

r = 1 feet

Step-by-step explanation:

Given that,

The surface area of the sphere, A = 4π feet²

We need to find the radius of the sphere.

The formula for the surface area of the sphere is given by :

A=4\pi r^2

Where

r is the radius of the sphere

Put all the values,

4\pi = 4\pi \times r^2\\\\r=1

So, the radius of the sphere is equal to 1 feet.

HELP IMMEDIATELY!!
Rashid [163]

Answer:

The value of c is 3

Step-by-step explanation:

Here, we want to get the value of c

From the question, we can select a single x-point

when x = 16

f(x) = 2

g(x) = -1

Thus;

g(16) = f(16) - c

-1 = 2 - c

c = 2 + 1

c = 3

A binomial probability experiment is conducted with the given parameters. Compute the probability of x successes in the n indepe
Naddik [55]

Answer:

P (X ≤ 4)

Step-by-step explanation:

The binomial probability formula can be used to find the probability of a binomial experiment for a specific number of successes.  It <em>does not</em> find the probability for a <em>range</em> of successes, as in this case.

 

The <em>range</em> "x≤4" means x = 0 <em>or</em> x = 1 <em>or </em>x = 2 <em>or</em> x = 3 <em>or</em> x = 4, so there are five different probability calculations to do.

 

To to find the total probability, we use the addition rule that states that the probabilities of different events can be added to find the probability for the entire set of events only if the events are <em>Mutually Exclusive</em>. The outcomes of a binomial experiment are mutually exclusive for any value of x between zero and n, as long as n and p don't change, so we're allowed to add the five calculated probabilities together to find the total probability.

 

The probability that x ≤ 4 can be written as P (X ≤ 4) or as P (X = 0 or X = 1 or X = 2 or X = 3 or X = 4) which means (because of the addition rule) that P(x ≤ 4) = P(x = 0) + P(x = 1) + P (x = 2) + P (x = 3) + P (x = 4)

Therefore, the probability of x<4 successes is P (X ≤ 4)
