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?
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

The length of each side of the cube shown is 5cm
Which equation can be used to find the volume of the cube
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

Answer:
the answer is B : 7
Step-by-step explanation:
Answer:
B. 7
Step-by-step explanation:
According to the word problem, Muna is dividing a piece of string that 42 2/3 long into 2/3 pieces.
[tex]\frac{14}{3} /\frac{2}{3}[/tex] (changed to an improper fraction)
Whenever dividing fractions, remember this:
SAME, CHANGE, RECIPROCAL (FLIP)
KEEP THE FIRST FRACTION THE SAME
CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN
FLIP THE SECOND FRACTION
[tex]\frac{14}{3} *\frac{3}{2} =\frac{42}{6}[/tex]
[tex]\frac{42}{6} =7[/tex]
I, therefore, believe Muna will have 7 pieces of string.

The swimming pool is opened 8 hours a day the pool manager must divide pool time equally among 5 groups; camp, camp swim team, swim lessons, family swim, and open swim how much time should she allow for each group?
Answer:
1.6 hours for each group
Step-by-step explanation:
8 / 5 = 1.6
1.6 x 5 = 8
you have to share 8 hours equally among 5 groups so its just 8 / 5 and you get 1.6 and thats how many hours each team is going to get

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

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