What is the surface area of the right cone below?

stellarik [79]

Answer:

A. 68 units2

Step-by-step explanation:

First of all to solve this problem we have to know the formula to calculate the surface area of the cone

A = area

r = radius = 4

L = 13

π = pi

A = π*r² + π*L*r

we replace with the known values

A = π * (4u)² + π * 13u * 4u

A = 16π u² + 52π u²

A = 68π u²

The surface area of the cone is 68π u²

At a highschool, 90% of the students take physics and 35% of the students take both physics and statistics. What is the probabil

7nadin3 [17]

Answer:

38.89% probability that a student that is taking Physics is also taking Statistics

Step-by-step explanation:

Conditional probability formula:

Two events, A and B.

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of B happening, given that A has happened.

$P(A \cap B)$ is the probability of these two events happening.

P(A) is the probability of A happening.

In this problem, we have that:

A: physics

B: statistics.

90% of the students take Physics

This means that $P(A) = 0.9$

35% of the students take both Physics and Statistics.

This means that $P(A \cap B) = 0.35$

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.35}{0.90} = 0.3889$

38.89% probability that a student that is taking Physics is also taking Statistics

You are adding air to a tire. The air pressure in the tire should be 24 27 200 pounds per square inch. What decimal should you w

vova2212 [387]

Answer:

P = 24.135 pounds per square inch

Step-by-step explanation:

The air pressure in the tire should be $24\dfrac{27}{200}$ pounds per square inch. This pressure is in the form of a mixed fraction. It is required to convert this pressure into a decimal form. We can convert it as follows :

$24\dfrac{27}{200}=\dfrac{(24\times 200)+27}{200}\\\\=24.135\ \text{pounds/square inch}$

In decimal form, the value of pressure in the tire on the digital pressure gauge is 24.135 pounds per square inch.
