Answer:
1.4
Step-by-step explanation:
Probability of selecting a red counter :
Number of red counter / total number of counters
5 / (5 + 3) = 5 /8 = 0.625
Probability of selecting a blue counter = 0.375
Let number of red counters :
0, 1 or 2
0 red counters :
Expected value = x * p(x)
0 + (0.625*1) + (0.390625 * 2)
0 + 0.625 + 0.78125 = 1.40625
Expected number of red counters = 1.4
A restaurant used 231 eggs last week. 46 of them are colored white, w. The remaining eggs are colored brown. Write an equation that represents the situation. ( i will give you brainly)
Answer:
46 + W = 231
Step-by-step explanation:
Answer:
My guess: 231 = 46 + b
Step-by-step explanation: Because they didn't mention how many were colored brown, we would use a variable to represent them, in this case I use b. But we do know 46 of them were white. so the equation would simply be 231 = 46 + b. After you add 46 and b you will get the total to 231. You can find b from subtracting 231 to 46. Then add b to 46 and get the total of 231
11. A bag contains 2 blue marbles and 2 green marbles. What is the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble?
Please show work ty
Answer: your answer should be 50%
Step-by-step explanation: This is because there are only four marbles in the bag total and only 2 are blue and only 2 are green so your chances of pulling out either is 50%
Answer:
33%
Step-by-step explanation:
2 blue marbles + 2 green marbles = 4 marbles
1st draw for blue: 2/4 (2 blue marbles out of 4 marbles)
2nd draw for green: 2/3 (1 less marble from 4, marble not put back in)
2/4 x 2/3 = 4/12 = 1/3 = 0.33 or 33%

A store purchases a shirt for $16.89. The store marks up the shirt by 20%. Right now, they are having a sale for 40% off any item. What is the sale price with a 7.25% tax?
Answer:
$13.04
Step-by-step explanation:
First, multiply 16.89 by 1.2, 0.6, and 1.0725. You should get a weird number on your calculator saying 13.042458, but just round 2 to the 4 ( 4 stays the same) and remove all the other numbers to get $13.04

XxKim02xXChoose ALL the lines PARALLEL to the following line: y = 2/9x - 7
y = 9/2x-12
y = 2/9x + 8
-2y = 9x + 8
9y = 2x -18
Answer: y = 2/9x + 8 and -2y = 9x + 8
Step-by-step explanation: Hope this help :D
Parallel lines have the same slope so y = 2/9x + 8 and 9y = 2x -18 will be parallel to the line y = 2/9x - 7 so option (B) and (D) will be correct.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
The equation of a linear line is given by
y = mx + x where m is slope
So,
y = 2/9x - 7 have slope as 2/9
Now since parallel lines have the slope same so all lines whose slope matches with 2/9 will be parallel to this.
So,
y = 2/9x + 8 has slope of 2/9
9y = 2x -18 ⇒ y = 2/9 x - 2 has slope of 2/9
Hence "y = 2/9x + 8 and 9y = 2x -18 will be parallel to the line y = 2/9x - 7"

Find the volume of the cylinder whose base area is (4x)2 and height is (5x)2.
Answer:
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
As we know that
The Volume of the cylinder is
= base × height
= (4x)^2 + (5x)^2
=16x^2 + 25x^2
= 41x^3
Hence, the volume of the cylinder is 41x^3
The volume of the cylinder will be [tex]20x^2[/tex] .
What is volume ?Volume is the amount of space that something contains or fills.
Volume [tex]=Length*Breadth*Height[/tex]
We have,
Base area [tex]=(4x)^2[/tex]
Height [tex]= (5x)^2[/tex]
So,
Volume of the cylinder [tex]=Base\ Area*Height[/tex]
[tex]= (4x)^2* (5x)^2[/tex]
Volume of the cylinder [tex]=20x^2[/tex]
Hence, we can say that the volume of the cylinder will be [tex]20x^2[/tex] .

The double dashes are both the same number. Since the base is 4cm and they have to be two of the same number, the double dashes are each 2cm long. Meanwhile, the height is 2cm, and the single dashes are two of the same numbers (but not 2cm, because that's what the double dashes are). So, each dash must be 1cm long.

A bag contains 9 and 54 blue marbles. If a representative sample contains 3 white marbles, then how many blue marbled would you expect to contain? Explain
Answer:
There should be 18 blue marbles in the representative sample.
Step-by-step explanation:
Given that a bag contains 9 white and 54 blue marbles, if a representative sample contains 3 white marbles, to determine how many blue marbles would you expect to contain the following calculation must be performed:
9 = 3
54 = X
54 x 3/9 = X
162/9 = X
18 = X
Therefore, there should be 18 blue marbles in the representative sample.
