The number of cubic centimeters that are in the volume of the cone is 12.5π cm³ OR 39.27 cm³

<h3>Calculating the volume of a cone</h3>

From the question, we are to determine the volume of the cone

The volume of a cone can be calculated by using the formula,

V = \frac{1}{3} \pi r^{2} h

Where V is the volume

r is the radius

and h is the height

From the given information,

radius, r = 2.5 cm

slant height, l = 6.5 cm

First, we will determine the height of the cone

By Pythagoras' theorem

l^{2} = r^{2} + h^{2}

Where l is the slant height

r is the radius

and h is the height of the cone

Then, we can write that

6.5^{2} = 2.5^{2} + h^{2}

42.25 = 6.25 + h^{2}

h^{2}=42.25 - 6.25

h^{2} =36

h = \sqrt{36}

∴ h = 6 cm

Now, putting the parameters into the equation for the determining the volume of a cone, we get

V = \frac{1}{3}\times \pi \times 2.5^{2} \times 6

V = \pi \times 6.25\times 2

V = 12.5 \pi cm³ OR 39.27 cm³

Hence, the number of cubic centimeters that are in the volume of the cone is 12.5π cm³ OR 39.27 cm³

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally
storchak [24]

Answer:

a) 0.1587

b) 0.0475

c) 0.7938

Step-by-step explanation:

Let's start defining our random variable.

X : ''Thickness (in mm) of ancient prehistoric Native American pot shards discovered in a Hopi village''

X is modeled as a normal random variable.

X ~ N(μ,σ)

Where μ is the mean and σ is the standard deviation.

To calculate all the probabilities, we are going to normalize the random variable X.

We are going to call to the standard normal distribution ''Z''.

[(X - μ) / σ] ≅ Z

We normalize by subtracting the mean to X and then dividing by standard deviation.

We can find the values of probabilities for Z in a standard normal distribution table.

We are going to call Φ(A) to the normal standard cumulative distribution evaluated in a value ''A''

a)

P(X

P(ZΦ(-1) = 0.1587

b)

P(X>7)=P(\frac{X-4.5}{1.5}>\frac{7-4.5}{1.5})

P(Z>1.666)=1-P(Z\leq 1.666)=

1 - Φ(1.666) = 1 - 0.9525 = 0.0475

c)

P(3

P(-1 Φ(1.666) - Φ(-1) = 0.9525 - 0.1587 = 0.7938
