There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting at least 1 blue?
Answer:
There is a 38% chance at least 1 was blue
Step-by-step explanation:
there are 8 marbles total 3 being blue. 3/8= .375 = 38%
The probability of getting at least 1 blue marble in the given situation is 0.375, i.e., 37.5%.
Probability is the ratio of favorable outcomes to the total number of outcomes.
It is given that there are 3 blue and 5 red marbles in the bag.
Therefore, the total number of marbles in the bag is 8.
Let's take two scenarios, one when one blue marble and one red marble are drawn and the second one when both marbles drawn are blue.
Let B and R be the events of drawing a blue marble and red marble, respectively.
Case 1:
The probability of getting one blue and one red marble is calculated as follows:
[tex]P(B =1, R=1) = \dfrac{3}{8}\times\dfrac{5}{7}[/tex]
[tex]= \dfrac{15}{56}[/tex]
Note that the replacement is prohibited.
Case 2:
The probability of getting two blue marbles is calculated as follows:
[tex]P(B =2) = \dfrac{3}{8}\times\dfrac{2}{7}[/tex]
[tex]= \dfrac{6}{56}[/tex]
The probability of getting at least 1 blue marble is given as follows:
[tex]P(B\ge1) = P(B =1, R=1) + P(B =2)[/tex]
[tex]= \dfrac{15}{56}+ \dfrac{6}{56}\\= \dfrac{21}{56}\\=\dfrac{3}{8}\\= 0.375[/tex]
Therefore, the probability of getting at least a blue marble is 0.375.

A baker uses 84 cups of flour for 36 batches of cookies. How many cups of flour are needed for 1 batch of the cookies?.
Answer:
23/10
Step-by-step explanation:
To find the unit rate divide 84 by 36
84 ÷ 36 = 2.3
To convert 2.3 to a faction
2.3 = 2.0 + 0.3
0.3 = 3/10
3/10 + 2 = 2 3/10
2 3/10 = 23/10

Step-by-step explanation:
First off, let's make a table for y = sin(x)
(x , y): (0 , 0) (π/2 , 1) (π , 0) (3π/2 , -1) (2π , 0)
Now, making our table for y = 4sin(x) is simple. We just have to multiply all the y-values from the previous table by 4.
(x , y): (0 , 0) (π/2 , 4) (π , 0) (3π/2 , -4) (2π , 0)
Plotting these coordinates, we get the graph depicted in letter B.

x+4y=9
if x = y+4
Answer:
4x + 8y =12 [inconsistent]
x + 2y = -3
x = 6 [inconsistent]
x = -2
2y = 5x + 6 [inconsistent]
-10x + 4y = 8
x - 3y=2
4x - 12y = 8 [dependent]
x+ 4y = 12 [independent]
2x - 8y = 4
4x + 8y = -6 [dependent]
6x + 12y = -9
4y - 2x = 6 [inconsistent]
8y = 4x -12
y - x = 0 [independent]
y = -x
2y - x = 4

Step-by-step explanation:
So you find 40% of 6000 ml
[tex]\frac{40 * 6000}{100 * 1}[/tex]
So 6000 times 40 is 240000
Then 100 times 1 is 100 leaving us with:
[tex]\frac{240000}{100}[/tex]
240000 divided by 100 is 2400 ml
So the car burns 2400 ml of oil.

Select all of the pieces of information that would tell you x and y have a proportional relationship. Let y represent the distance between a rock and a turtle's current position in meters and x represent the number of minutes the turtle has been moving. y=3x After 4 minutes, the turtle has walked 12 feet away from the rock. The turtle walks for a bit, then stops for a minute before walking again. The turtle walks away from the rock at a constant rate.
Answer:
y=3x
The turtle walks away from the rock at a constant rate.
Step-by-step explanation:
A proportional relationship is one in which the two variables vary directly with each other and can be represented by the equation:
y = kx, where k is the constant of proportionality.
Also, a proportional relationship has a constant rate which is the ratio of the two variables.
A) The equation y = 3x is a proportional relationship because it is in the form y = kx, k =3
B) After 4 minutes, the turtle has walked 12 feet away from the rock.
We cant say that this is a proportional relationship because it may or may not be proportional.
C) The turtle walks for a bit, then stops for a minute before walking again.
It is not proportional
D) The turtle walks away from the rock at a constant rate
This is a proportional relationship because it has a constant rate
