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.

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]

Answer:
oranges $3.50 per Kg, bananas $3 per Kg
Step-by-step explanation:
let b represent cost of bananas and o represent cost of oranges , then
2b + 3o = 16.5 → (1)
o = b + 0.5 → (2)
substitute o = b + 0.5 into (1)
2b + 3(b + 0.5) = 16.5 ← distribute parenthesis on left side and simplify
2b + 3b + 1.5 = 16.5
5b + 1.5 = 16.5 ( subtract 1.5 from both sides )
5b = 15 ( divide both sides by 5 )
b = 3
substitute b = 3 into (2)
o = 3 + 0.5 = 3.5
cost of oranges = $3.50 and cost of bananas = $3

4. Shelton earns an hourly wage at a grocery store. The following expression represents Shelton’s take home pay after taxes, social security, and his health care plan are deducted. Let x represent the number of hours Shelton worked.
10.25x − 0.21(10.25x)
a) Which term represents Shelton’s total pay before deduction?
b) Shelton wants to save $1,675 for a new laptop. If Shelton saves 25% of his take-home pay, how many hours will he need to work to meet his savings goal?
Answer:
a) Shelton’s total pay before deduction: 10.25x
b) To meet savings goal he'll have to work 827.415869 hours.
Step-by-step explanation:
Take-home pay:
10.25x − 0.21(10.25x)
10.25x − 2.1525x
8.0975x
Save 25% for new laptop:
.25(8.0975x) = 1675
2.024375x = 1675
x = 827.415869 hours

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.
