There are 3 blue marbles, 6 red marbles, 2 green marbles and 1 black marble in a bag. Suppose you select one marble at random. Find the probability for each of the following.

Answers

Answer 1

a) The probability of selecting a blue marble is P ( B ) = 1/4

b) The probability of selecting a green marble is P ( G ) = 1/6

c) The probability of selecting not a green marble is P' ( G ) = 5/6

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the number of blue marbles = 3

Let the number of red marbles = 6

Let the number of green marbles = 2

Let the number of black marbles = 1

So , the total number of marbles = 12

So , the probability is given as

The probability of selecting a blue marble is P ( B ) = 1/4

The probability of selecting a green marble is P ( G ) = 1/6

The probability of selecting not a green marble is P' ( G ) = 5/6

Hence , the probability is solved

3/5

Step-by-step explanation:

there are 5 cards and chances of picking 4 or 7 which are three cards (since there are two 7s) gives u a probability of 3/5 or 60% chance.

3/5 because there is two 7 and one 4 and 5 numbers total so add the two 7 and one 4 it’s 3 out of the 5 numbers

Step-by-step explanation:

if one of the factor of x²+x-20 is (x+5) find other factor​

Answers

Answer:

Step-by-step explanation:

x^2+x-20

=x^2-(5-4)x-20

=x^2-5x+4x-20

=x(x-5)+4(x-5)

=(x-5)(x+4)

therefore the other factor is (x+4)

Answer:

(x - 4)

Step-by-step explanation:

METHOD 1 (Long Division Method):-

[See the attachment for full solution of Method 1]

One factor of x² + x - 20 is already given. To find the other factor , divide the polynomial with the factor and the quotient you'll get after dividing will be the second factor of the polynomial.

METHOD 2 (Factorising) :-

Factorise x² + x - 20.

Split the middle terms.

[tex]=> x^2 + 5x - 4x - 20[/tex]

Take 'x' common from first two terms and take '-4' common from last two terms.

[tex]=> x(x + 5) - 4(x + 5)[/tex]

Take '(x+5)' whole common from the expression.

[tex]=> (x + 5)(x - 4)[/tex]

(x + 5) & (x - 4) are the factors of x² + x - 20.

A restaurant customer left $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax.

Answers

Answer:

17.50

Step-by-step explanation:

you really don't need to know the tax amount.

20% of x = 3.50

(20/100) x = 3.50  Divide top and bottom of the left number by 20

(20÷20) / (100÷20)  *  x = 3.50

(1/5) x = 3.50           Multiply both sides by 5  

x = 3.50 * 5

x = 17.50

The meal cost 17.50

Find the length of arc XW. Round your answer to the nearest hundredth.

Answers

Answer:

15.08 m

Step-by-step explanation:

The angle XZW :

XZW + 108° = 180°

XZW = 180° - 108°

XZW = 72°

Length of an arc = θ / 360 * πd

d = diameter = XV = 24

Length of arc XW = (72/360) * π * 24

Length of arc XW = 15.0796

Step-by-step explanation: The mean is basically the average. So, start by lining up the numbers from smallest to largest. 1, 3, 4, 8, 14, 18, 19, 19, 22. Then, add them all together. You get 108. Then, divide 108 by the number or numbers in the data set, which in this case is 9. So 108 divided by 9 = 12. Your answer is A. --> 12

Jack tool out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?

Answers

Answer:

A = $32,732.58  

A = P + I where

P (principal) = $25,000.00

I (interest) = $7,732.58

Step-by-step explanation:

Given data

Time= 6 years

Principal=  $25,000

Rate= 4.5%

First, convert R as a percent to r as a decimal

r = R/100

r = 4.5/100

r = 0.045 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 25,000.00(1 + 0.045/12)^(12)(6)

A = 25,000.00(1 + 0.00375)^(72)

A = $32,732.58

Se va a colocar una escalera que mide 5 metros (m) de longitud sobre una pared. El fabricante de la escalera recomienda que, por seguridad, el ángulo que forme la escalera con el piso sea de 78°, ¿Cuál será la distancia sobre el piso del pie de la escalera a la pared?

Answers

Answer:

4.9 m

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de seno

sin θ = Opuesto / Hipotenusa

θ = 78 °

Hipotenusa = Longitud de la escalera = 5 m

Opuesto = Distancia sobre el suelo = x

sin 78 = x / 5m

Help..? Pleaseee , it has to do with the Pythagorean Theorem. But I have no idea how to do it

Answers

Pythagorean Theorem is

a ²+ b ² = c ²

a and b are the shorter sides, while c is the hypotenuse, or longest side. Let’s say the side we are looking for is “b”.

Let’s first rearrange the equation, then sub in.

a ²+ b ² = c ²
b ² = c ²- a ²
b = √ (c ²- a ²)
b = √(17 ²- 15 ²)
b = √(289-225)
b = √ 64
b = 8

Answers

I’m pretty positive it’s Quantitative

Answer:

It is Quantitative.

Step-by-step explanation:

Quantitative data is information about quantities; information that can be measured with numbers.

Qualitative data describes qualities or characteristics; information collected using questionnaires, interviews, or observation, and frequently appears in narrative form.

Examples:

It is 25° Celcius today. - Quantitative

I drooled after smelling freshly baked cookies. - Qualitative

Tips:

Think of Quantitative as Quantity; numbers.

Think of Qualitative as Quality; description/characteristics.

Answers

Answer:

I think that the answer is true (explanation might not be 100% accurate)

Step-by-step explanation:

Given that for 2 lines to be parallel, they have to never intersect at any point, meaning they both have to be straight and "facing" the same way. If either line has a tilt/angle of any sort, then they are not parallel.

Someone please help me with this im not good with graphs.​

Answers

Answer:

1

Step-by-step explanation:

1. To get the slope, you need to divide the rise by the run.

2. Pick two points each on the X-axis and pick corresponding points on the Y axis and then name them y2, x2 and y1, x1.

3. The rise will be y2-y1

4. The run will be x2-x1

5. Therefore, the slope is rise/run = (y2-y1)/(x2-x1)

In this case, let's take 2 on the X axis as x2 and the corresponding point on the Y axis  as y2 which in this case happens to also be 2.

Now, let's take 1 on the X axis as x1 and the corresponding point on the Y axis  as y1 which is also 1.

now using the formula (y2-y1)/(x2-x1), we get: slope = (2-1)/(2-1) = 1

Answers

Answer:

Expected number of winners with 52 contestants:52*5/13 = 20.The experiment result is almost twice less (12 vs 20).In order to change the results of experimental probability some of the letters may need swapped, (probably the letters are in alphabet order) but for this we need more data.

Experimental probability is probability that is determined on the basis of the results of an experiment repeated many times. Theoretical probability is probability that is determined on the basis of reasoning. Probability is a value between (and including) zero and one.

Ob
117.3 cubic mi.
Ос
29.3 cubic mi.
Od
7.3 cubic mi.

Answers

Answer:

c. 29.3 cubic mi

Step-by-step explanation:

Applying,

V = πr²h/3.............. Equation 1

Where V = volume of the cone, r = radius of the circular base, h = height of the cone, π = pie

From the diagram,

Given: h = 7 mi, r = 2 mi

Constant: π = 3.14

Substitute these values into equation 1

V = 3.14(7×2²)/3

V = 29.3 cubic mi

Hence the right answer is c. 29.3 cubic mi
