A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?
A quick lesson on probability:
The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity of flipping a coin and getting heads is:
(1 way to get heads) / (2 possible outcomes) = 1/2
Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.
On to the problem.
There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.
Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.
Using the formula to find the probability, substitute the values we just found.
(the number of ways what you want can happen) / (total number of outcomes possible) =
(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.
Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black
7/20 * 100 = 35 times, or D

Find x and y in the given figure
Answer:
x= 70°, y=40°
Step-by-step explanation:
2x=140
x= 70
y= 180-140= 40
140 + y = 180
y = 180 - 140
y = 40
2x + 40 = 180 (Angle Sum Property)
2x = 180 - 40
2x = 140
x = 140/2
x = 70
X = 70
Y = 40

Answer:
1. 8x + 3y - x - 2y
= 8x - x + 3y - 2y
= 7x + y
2. 3n - 7n - 2n + x + 8x
= 3n - 9n + 9x
= - 6n + 9x
3. 2r - 5n + 9y - 3r + n
= 2r - 3r - 5n + n + 9y
= -r - 4n + 9y
4. 12y - 6x + 5y - 3n
= 12y + 5y - 6x - 3n
= 17y - 9n
5. - 13n + 4n - r
= -9n - r
6. 7xy - 8x + 6xy - y
= 7xy + 6xy - 8x - y
= 13xy - 8x - y
7. - 14r - 10n - 3r - 9n
= -14r - 3r - 10n - 9n
= - 17r - 19n
8. 6r + 9r - 2r - 13n
= 6r + 7r - 13n
= 13r - 13n
9. n + r + x - 3x +4r
= n + r + 4r + x - 3x
= n + 5r - 2x
10. 15y - 7x + 9z + 4z - 3x
= 15y - 7x - 3x + 9z + 4z
= 15y - 10x + 13z

Andrew McCutchen hit 18 homeruns in 9 baseball games. At this rate, how many homeruns will he have hit
in 11 baseball games?
Please show how to do it
Answer:
if it's 18 home runs in 9 baseball games
then you're dividing 18 by 9 which is 2 home runs for every 9 baseball games
to prove if you're right (9×2=18)
if it's 11 baseball games then 11×2=22
Hope It Helps ☺️
Andrew McCutchen hit 18 a number of homeruns in 9 baseball games. . which is determined by the given proportion.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Given that he hit 18 homeruns in 9 baseball games.
Let the number of homeruns would be x will he have hit in 11 baseball games.
According to the given question, we can write a proportion as
18 homeruns : 9 baseball games = x homeruns : 11 baseball games.
18 / 9 = x / 11
Apply the cross-multiplication operation,
18 × 11 = 9x
9x = 198
x = 198 / 11
Apply the division operation,
x = 18
Therefore, he hit 18 a number of homeruns in 9 baseball games.

Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)
