A graduated cylinder is filled with 36 cm 3 of liquid the liquid is poured into a different cylinder that has a radius of 3cm ,
Mila [183]

The height of the liquid in the new cylinder is about 1.72 cm

Step-by-step explanation:

The formula of the volume of a cylinder is V = πr²h, where

  • r is the radius of the base of the cylinder
  • h is the height of the cylinder

∵ The volume of the liquid = 36 cm³

∵ The liquid is poured into another cylinder with radius 3 cm

∵ The radius of the base = 3 cm

- To find the height of the liquid in the new cylinder equate the rule

   of the volume by 36

∵ V = πr²h

∴ π(3)²h = 36

∴ 9πh = 36

- Divide both sides by 9π

∴ h = 1.273239545

The height of the liquid in the new cylinder is about 1.72 cm

Justin shoots in an air rifle competition. Out of 30 targets he hit 12 bulls eyes. What is the probability that on his next atte
MrRissso [65]

Answer:

Q1. Empirical Probability

Q2. 7:3

Q3. "The spinner landing of 1, 3, 5, or 7"

Step-by-step explanation:

Q1.

This is the type of probability that depends on experiment and what has happened before.

Subjective Probability is based on intuition. It is vague.

Empirical probability depends on experiment and on what has happened to know what will happen.

Theoretical probabilty is is the theory behind probability aka. classical probability.

Authentic probability is more like real life probability.

From the definitions, we see that the condition given, it is Empirical probability because Justin's next shooting on target will depend on his previous "experiment" of hitting bulls eye 12 out of 30 times.

Hence, the answer is Empirical Probability

Q2.

The odds of event happening are the ratio of "event happening" to "event not happening".

So, event happening is 70% or 0.7

Event not happening, is thus, 1 - 70% = 30% = 0.3

Odds are 0.7:0.3

or

7:3

Q3.

The complement of an event is 1 - event. Or simply, the complement is chances of event not happening.

We want complement of "even number", so that would be only "odd numbers".

From the answer choices, 2nd answer choice is right because it only has ODD NUMBERS.
