Andrews [41]2 years ago

6 0

Answer:

5/19

Step-by-step explanation:

Marbles=20

So the probability of choosing not yellow is 10/20=1/2.

Marbles are not replaced.

The total number is 19

The probability of choosing yellow is 10/19

So the final answer is (1/2)*(10/19)=5/19.

hope this helps

What is the volume of a cone with a radius of 2 and a height of 19?

kykrilka [37]

Remember that the cone volume formula is $V=\pi r^2\frac{h}{3}$ , with r = radius and h = height. Using our information, we can form our equation as such: $V=\pi 2^2\frac{19}{3}$ (I'll be keeping the answer in pi form.)

Firstly, solve the exponents: $V=\pi 4\frac{19}{3}$

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3

What does the atomic mass of an atom tell us?

Scorpion4ik [409]

The atomic mass of an atom tells us about how much the atom weighs.

Option A

<u>Step-by-step explanation:</u>

The atomic mass of an atom tells us about the weight of the atoms. An atom can be represented using the mass number denoted as A and atomic number denoted by Z. As atomic number is the number of protons present in the atom, mass number denotes the sum of protons and neutrons present in the atom.

So, the mass number will be approximately equal to the atomic mass. It can be also stated that atomic mass represents the weight of the atoms. The elements are arranged in the increasing order of their atomic mass in the periodic table.

Can someone help me with this

The center of the circle is (h,k) = (-2,-3)

The radius of the circle is r = 2

The standard form of equation of the circle is

${(x + 2)}^{2} + {(y + 3)}^{2} = 4$

<h3>How to find the center, radius and standrad form of the circle?</h3>

The general form of equation of the circle is

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

Here, (h,k) means centre of the circle.

r means radius of the circle.

given that coordinate points of centre of circle is (-2,-3).

Hence the (h,k) = (-2,-3)

<h3>How to find the radius of the circle?</h3>

Now to find the radius of the circle

The distance from a circle's centre to its circumference is its radius.

The distance from a circle's centre (-2,-3) to its circumference (0,-3) is its radius.

using the formula, distance between the two points to obtain radius.

$d = \sqrt{(x1 - x2) {}^{2} + {(y1 - y2)}^{2} } \\ r = \sqrt{ {( - 2 - 0)}^{2} + {( - 3 - ( - 3))}^{2} } \\ r = \sqrt{ {( - 2)}^{2} + {( - 3 + 3)}^{2} } \\ r = \sqrt{ {4}^{2} + 0 } \\ r = \sqrt{4} \\ r = 2$
