Step-by-step explanation:
A bag contains 5 white, 3 black, and 2 green balls. Balls are picked at random.
Explain why the events picking a black ball and then another black ball are
dependent. Then identify the probability,
Answer:
look down there
Step-by-step explanation:
First ball:
Probability of drawing a white ball is 5/8
Probability of drawing a black ball is 3/8
Second ball:
This depends on the first ball drawn, lets say you drew a white ball initially, 4 white balls are left out of 7 balls in total. The probability of a white ball in the second pick is 4/7.
Total probability of drawing two white balls is 5/8*4/7 (since they are independent events).
If you picked a black ball initially, picking another black ball would have a probability of 2/7, on similar grounds , total prob for 2 blacks would be 3/8*2/7.
The probability that you pick 2 balls of same color is (5/14 + 3/28) = 13/28. (Since they are mutually exclusive events)
The probability of picking a black ball and then another black ball is; Due to conditional probability and is equal to 1/15
How to solve conditional probability?
Conditonal probability means that the probability of one event is affected or depends on the probability of another event.
Now, total balls in the bag is;
Total balls = 5 + 3 + 2
Total balls = 10 balls
Probability of first picking a black ball is;
P(black ball first) = 3/10
Now, when a black ball is picked, there will ba 9 balls left in the bag of whih only 2 are black. Thus, the probability of picking another black ball is;
P(black ball second) = 2/9
Thus;the probability of picking a black ball and then another black ball is;
P(black ball | black ball) = 3/10 * 2/9
P(black ball | black ball) = 1/15

Describe the process you would use to find the solution to the problem 3 1/4 minus1 1/3. Express your answer numerically and with a graphical representation.
Answer:
1 11/12
Step-by-step explanation:
Notice (right away) that the denominators of the fractions are different (4 and 3).
Identify the LCD: It is 12.
Convert the two given numbers to mixed numbers with LCD 12:
3 3/12
-1 4/12
-----------
4/12 is greater in magnitude than 3/12, so we must 'borrow' from the digits' place. Recall that 1 = 12/12.
Then 3 3/12 = 2 15/12. -1 4/12 stays the same; it has LCD 12.
Then, perform the indicated subtraction:
2 15/12
-1 4/12
------------
1 11/12 (answer: this is the difference "3 1/4 less 1 1/3")

Says that the value of some number must always be less than 10.
Since it is not less than or equal to, it is not cost is at most 10. it must be (the bag contains fewer than 10 carrots)
c > 10
Says that the value of some number must always be greater than 10

Answer:
c<10 --------> The bag contains fewer than 10 carrots
c>10 ---------> Catherine biked farther than 10 miles
c<20 ---------> The chair is shorter than 20 inches
c>20 ----------> Carlos scored over 20 goals.
Step-by-step explanation:
C is less than 10 so there had to be fewer than 10. So there are less that 10 carrots in the bag.
C is greater than 10 so there has to be more than 10. So she biked more than/farther than 10 miles.
C is less than 20 so there has to be less than 20. So the chair is shorter/less than 20 inches.
C is greater than 20 so there has to be more than 20. So carlos scored over/more than 20 goals.

Answer:
91ft^2
Step-by-step explanation:
A = w*l
first, solve for the bottom rectangle
w = 7ft
l = 8ft
7ft * 8ft = 56ft^2
then for the second rectangle
l = 5ft
w = 7ft
5ft*7ft = 35ft^2
total area = rectangle 1+2
so 35ft^2+56ft^2=91ft^2
Answer:
The answer for the Area of the shape is 91ft²
Step-by-step explanation:
Area of the shape =Area of Bigger rectangle+ Area of small rectangle
A=L×B+l×b
A=7×8+5×7
A=56+35
A=91ft²

Use diagrams or the description of equivalent ratios to show that the ratios 2:3, 4:6, and 8:12 are equivalent ratios.
They are equivalent because 2:3, 2 × 2 = 4, 3 × 2 = 6 which makes up 4:6, 2 × 4 = 8, 2 × 6 = 12 which makes it 8:12. which makes it 2.
Yes, All the ratio 2 : 3, 4 : 6 and 8 : 12 are equal.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
All the ratios are,
⇒ 2 : 3, 4 : 6 and 8 : 12
Now,
Since, All the ratios are,
⇒ 2 : 3, 4 : 6 and 8 : 12
Hence, Simplify the ratio as;
⇒ 2 : 3 = 2/3
⇒ 4 : 6 = 4 / 6
= 2 / 3
= 2 : 3
⇒ 8 : 12 = 8 / 12
= 4 / 6
= 2 / 3
= 2 : 3
Thus, All the ratio are equal.

*****100 POINTS****** please help me with this area of a circle question.
Answer: 12 cm
Step-by-step explanation: In order to do this, you have to know that the formula for the area of a circle is pir^2. Pi times the radius squared is equal to 36 pi. Well, 6 squared is 36, and 36 times pi is 36 pi. So that means that the radius is 6. Then, the radius is half the diameter, so the diameter is 12.
