A jar contains 2 red, 5 green, 2 blue and 6 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a green and then a yellow marble?

Answers

Answer:

Step-by-step explanation:

The probability of picking an item A in a box of N items depends on nA, the amount of items A in the box at the time of picking, with the kinda instinctive value:

p = nA / N

then it means that if you have no green ball, the probability is 0/N = 0, if you only have green balls, it means you have a probability of N/N = 1 = 100%, and if you have as many green balls as non-green balls, you have a probability of nA/(2nA) = 0.5 = 50%.

Here the probability of first picking a green ball (nG=5) in a box of N=3+5+2+6=16 for the 1st pick is:

pG1 = 5/16

Now the trick here is that once you picked the green ball, you put it back in the box before picking another ball. So you still have N=16 balls for the second pick, and the probability of picking a yellow ball (nY=6) for the 2nd pick is:

pY2 = 6/16 = 3/8

(it would have been slightly higher, at 6/15, if you did NOT put back the green marble in the box).

Now you want BOTH events to be true. So you want G1 to be true AND Y2 to be true. The two events are independent (the probability of Y2 is 6/16 if you had G1 but is also 6/16 if you failed G1), so the probability of having both is simply done by multiplicating them:

pG1Y2 = pG1 * pG2 = 15/128

Will give brainliest!! Using the measurements of the shapes.. determine the area and perimeter of the irregular polygon.

Answers

Answer:

[tex]p=28.2\:\text{units},\\A=40.2\:\text{square units}}[/tex]

Step-by-step explanation:

The irregular shape's area consists of the sum of the areas of all the shapes that make it up.

Area of pink triangle: [tex]\frac{1}{2}\cdot 3 \cdot 3=4.5[/tex]

Area of purple square: [tex]3^2=9[/tex]

Area of green quadrilateral: [tex]3\cdot 2.9=8.7[/tex]

Area of blue triangle: [tex]\sqrt{10.25(10.25-8.5)(10.25-6)(10.25-6)}=17.99989[/tex]

Therefore, the area of the irregular polygon is [tex]4.5+9+8.7+17.99989\approx \boxed{40.2\:\text{square units}}[/tex].

The perimeter of the irregular polygon consists of certain shred sides from the four polygons that make up:

[tex]p=3+3+3+4.2+3+6+6=\boxed{28.2\:\text{units}}[/tex]

The length of each side of the cube shown is 5cm

Which equation can be used to find the volume of the cube

Answers

Answer:

5 x 5 x 5 = 5 ³ = 125 cm ³

Step-by-step explanation:

The formula for volume is l x w x h

length = 5cm

width = 5cm

height = 5cm

therefore, equation is 5 x 5 x 5 = 125 cm ³

volume = length x width x height

length-5
width-5
height-5

5 x 5 x 5 = 125 units
(p.s make sure you say 125 units cubed or put a small 3 while using volume)!

Answer:

$268.38

Step-by-step explanation:

First we will take off the 20% off the 315 dollars. SO we can do this by saying that the discounted price is 80% of the original price, (because 100 - 20 = 80). So 0.8 * 315 = 252. So 252 = discounted price. So then we have to add the tax price.

Sales tax is %6.5, so we can do 252*0.065 to find the tax payed. We get 16.38, so we can dd this to our discounted price to get 252 + 16.38, or $268.38

$268.38 is the correct answer

In this speech Roosevelt termed, for the first time, journalists as muckrakers.SATURDAY, APRIL 14, 1906In Bunyan's Pilgrim's Progress you may recall the description of the Man with the Muck-rake, the man who could look no way but downward, with the muck-rake in his hand; who was offered a celestial crown for his muck-rake, but who would neither look up nor regard the crown he was offered, but continued to rake to himself the filth of the floor.In Pilgrim's Progress the Man with the Muck-rake is set forth as the example of him whose vision is fixed on carnal instead of on spiritual things. Yet he also typifies the man who in this life consistently refuses to see aught that is lofty, and fixes his eyes with solemn intentness only on that which is vile and debasing. Now, it is very necessary that we should not flinch from seeing what is vile and debasing. There is filth on the floor and it must be scraped up with the muck-rake; and there are times and places where this service is the most needed of all the services that can be performed. But the man who never does anything else, who never thinks or speaks or writes, save of his feats with the muck-rake, speedily becomes, not a help to society, not an incitement to good, but one of the most potent forces for evil.There are, in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man whether politician or business man, every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful. . . To assail the great and admitted evils of our political and industrial life with such crude and sweeping generalizations as to include decent men in the general condemnation means the searing of the public conscience. There results a general attitude either of cynical belief in and indifference to public corruption or else of a distrustful inability to discriminate between the good and the bad. Either attitude is fraught with untold damage to the country as a whole. The fool who has not sense to discriminate between what is good and what is bad is well-nigh as dangerous as the man who does discriminate and yet chooses the bad. There is nothing more distressing to every good patriot, to every good American, than the hard, scoffing spirit which treats the allegation of dishonesty in a public man as a cause for laughter. Such laughter is worse than the crackling of thorns under a pot, for it denotes not merely the vacant mind, but the heart in which high emotions have been choked before they could grow to fruition.What was Roosevelt warning against in these sentences? I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful. . .
