Step-by-step explanation:
Are the events of drawing a rook from the bag of white
pieces and then drawing the king from the bag of
black pieces dependent or independent events? Find
the probability of this compound event.
Answer:
Independent events, 1/16
Step-by-step explanation:
What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.
Which means that they are independent events.
And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.
solve 5x^2-4x-2=0 by completing the square
Answer:
Hello
Here's the answer:
2x^2 + 5x + 2 = 0\\ 2x^2+4x+x+2=0\\ 2x(x+2)+1(x+2)=0\\ (2x+1)(x+2)=0\\ x=-\frac{1}{2} \vee x=-2
x^2-4x+1=0\\ x^2-4x+4-3=0\\ (x-2)^2=3\\ x-2 =\sqrt3 \vee x-2=-\sqrt3\\ x=2+\sqrt3 \vee x=2-\sqrt3

4(2x-3)+8(x-4)=2(2x+6) help plzzz
Answer:
x = 14/3
Step-by-step explanation:
4(2x-3)+8(x-4)=2(2x+6)
Distribute
8x -12 +8x - 32 = 4x +12
Combine like terms
16x -44 = 4x+12
Subtract 4x
16x-4x -44 = 4x+12-4x
12x -44 =12
Add 44 to each side
12x-44+44 = 12+44
12x = 56
Divide each side by 12
12x/12 = 56/12
x = 14/3
Answer:
[tex]x=\dfrac{14}{3}[/tex]
Step-by-step explanation:
[tex]4(2x-3)+8(x-4)=2(2x+6)[/tex]
Expand parentheses:
[tex]8x-12+8x-32=4x+12[/tex]
Combine similar terms:
[tex]16x-44=4x+12[/tex]
Subtract 4x and add 44 to both sides:
[tex]12x=56[/tex]
Divide both sides by 12:
[tex]x=\dfrac{14}{3}[/tex]

12x−39≤9 AND−4x+3<−6
Answer:
2 1/4 < x ≤ 4
Step-by-step explanation:
12x−39≤9 AND−4x+3<−6
Solve them separately and then put back together
12x−39≤9
Add 39 to each side
12x−39+39≤9+39
12x ≤48
Divide by 12
12x/12 ≤48/12
x ≤4
Now the other inequality
−4x+3<−6
Subtract 3 from each side
−4x+3-3<−6-3
-4x < -9
Divide by -4, remembering to flip the inequality
-4x/-4 > -9/-4
x > 2 1/4
put back together
x > 2 1/4 and x ≤4
2 1/4 < x ≤ 4
Answer:
2.25<x≤4
Step-by-step explanation:
12x−39≤9 ⇒ 12x≤ 48 ⇒ x≤4
−4x+3<−6 ⇒ -4x < -9 ⇒ x> 9/4= 2.25
2.25<x≤4
or
x= (2.25, 4]

b. $117.24
C. $252.84
d. $381.82
Answer:
The correct option is A,$48.75
Step-by-step explanation:
The amount of spend on theater tickets is missing, however it can be computed by using the below formula:
Closing balance=opening balance-cost of groceries+ rebate check-cost of gas-cost of theater tickets+ paycheck
$695.15=$430.57-$57.19+$15-$22.30-cost of theater tickets+$377.82
cost of theater tickets=$430.57-$57.19+$15-$22.30+$377.82-$695.15
cost of theater tickets=$48.75

PLS HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
42
Step-by-step explanation:
Set the numbers in order from least to greatest, then find the one in the middle, which will be the median.
19, 23, 42, 56, 67
42 is in the middle, so it is the median.
What is the sum? 2/x^2+4/x^2
Answer:
\frac{2}{ x^{2} } + \frac{4}{ x^{2} } = \frac{2+4}{ x^{2}}= \frac{6}{ x^{2} }
Step-by-step explanation:
When we add two expression in fraction we take Least common multiple of two expression in the denominator
Here we have expression
Now, we write a common denominator
rewrite the expression
Now, we combine the numerator 2+4 is equal to 6
So, we will get = \frac{2}{x^{2}}+ \frac{4}{x^{2}} =\frac{6}{x^{2} }

The graph of y=54x+1 is shown below. The coordinate (0,y) is a solution of the equation. Given the x-value of 0, what is the value of the y-coordinate for the coordinate (0,y)?
Answer: y =1
Step-by-step explanation:
Evaluating the equation for x = 0:
y = 54 (0) + 1
y =1
The y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The missing figure is attached to the picture.
Calculataing the equation for x = 0:
y = 54 (0) + 1
y = 1
Thus, the y-coordinate for the coordinate (0, y) is 1 if the coordinate (0,y) is a solution to the equation. Given the x-value of 0.

What are simultaneous linear equations?Simultaneous linear equations can be defined as the two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
3x-y=9 - - - -(1)
4x+y=5 - - - - (2)
Adding equations 1 and 2
7x = 14
x = 2
Now, we have
3(2) - y = 9
-y = 9 - 6
-y = 3
y = -3
Thus, the solution of the given simultaneous equations are x = 2 and y = -3.

Which equation represents a line which is parallel to y = 0?
A. y = 6
B. x = -5
C. y = x
D. y = x - 1
Answer:
A. y = 6
Step-by-step explanation:
Y= 0 is equation of x - axis
equation of any straight line which is parallel to x-axis and at distance of a from it is given y = c.
Therefore, from the given option only option A y =6 is in form of y = a and hence is the correct answer.
_______________________________________
Also we know that for two lines to be parallel , their slope should be equal.
slope of line y = mx + c is m
slope of y = 0 here m = 0, hence slope is 0
out of the given option
only for y - 6 slope is 0 and hence it is the correct answer.
