Answer:
[tex]slope = \dfrac{-2}{5}[/tex]
Step-by-step explanation:
The slope of a line passing through points , [tex] (x_1,y_1) [/tex] and [tex] (x_2,y_2) [/tex] is ,
[tex]\implies slope = \dfrac{y_2-y_1}{x_2-x_1}[/tex]

Given P(A) = 0.44, P(B) 0.6 and P(An B) = 0.394, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.
Answers
Given:
[tex]P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394[/tex].
To find:
The value of [tex]P(A\cup B)[/tex], rounding to the nearest thousandth.
Solution:
We know that,
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
On substituting [tex]P(A)=0.44,P(B)=0.6,P(A\cap B)=0.394[/tex], we get
[tex]P(A\cup B)=0.44+0.6-0.394[/tex]
[tex]P(A\cup B)=0.646[/tex]
Therefore, the value of [tex]P(A\cup B)[/tex] is 0.646.

x=4 and y=3
Step-by-step explanation:
Ah Algebra...
2x-3y=-1
y=x-1
Let's solve your system by substitution.
2x−3y=−1; y=x−1
Rewrite equations:
y=x−1;2x−3y=−1
Step: Solve
y= x−1
Step: Substitute x−1 for y in 2x−3y=−1:
2x−3y=−1
2x−3(x−1)=−1
−x+3=−1(Simplify both sides of the equation)
−x+3+−3=−1+−3(Add -3 to both sides)
−x=−4−x−1=−4−1
(Divide both sides by -1)
x=4
Step: Substitute4forxiny=x−1:
y=x−1
y=4−1
y=3(Simplify both sides of the equation)
Answer:
x=4 and y=3

Answer:
(4,3)
Step-by-step explanation:
Being that the y variable is isolated in the second equation, the other side of that equation can be substituted for y in the first equation.
[tex]2x - 3(x - 1) = - 1[/tex]
Now simplify for x.
[tex]2x - 3x + 3 = - 1 \\ - x = - 4 \\ x = 4[/tex]
Now with that, insert the x value in for x in the second equation.
[tex]y = (4) - 1 \\ y = 3[/tex]
Now the correct answer is (4,3)

100.25x = 2005
x=20 <- the amount of sugar at the equilibrium point.
7500 + 100.50(20)
7500 + 2005
$9505 <- the cost at that point. ■

B. 187 ways
C. 1,260 ways
D. 1,500 ways
Answers
Answer:
A
Step-by-step explanation: add 15+12+7
if im write can i get a brainliest? plss:>
The band director can create a trio in 1,260 different ways.
Hence, option C is correct.
Use the concept of permutations,
The formula for permutations is,
⇒ [tex]^{n}P_{r}[/tex] = n! / (n - r)!
Where n is the total number of items and r is the number of items we are selecting.
So in this case, we have,
⇒ n = 15 clarinet players
⇒ n = 12 flute players
⇒ n = 7 saxophone players
⇒ r = 1 clarinet player,
1 flute player, and 1 saxophone player
To find the number of ways we can create a trio with one player from each instrument, we need to calculate,
⇒ ([tex]^{15}P_{1}[/tex]) x ([tex]^{12}P_{1}[/tex]) x ([tex]^{7}P_{1}[/tex])
⇒ ([tex]^{15}P_{1}[/tex]) = 15! / (15 - 1)!
= 15! / 14!
= 15
This represents the number of ways we can choose one clarinet player out of 15.
([tex]^{12}P_{1}[/tex]) ) = 12! / (12 - 1)!
= 12! / 11!
= 12
This represents the number of ways we can choose one flute player out of 12.
[tex]^{7}P_{1}[/tex] = 7! / (7 - 1)!
= 7! / 6!
= 7
This represents the number of ways we can choose one saxophone player out of 7.
So the total number of ways we can create a trio consisting of one clarinet player, one flute player, and one saxophone player is,
⇒ 15 x 12 x 7 = 1,260
Therefore,
The band director can create a trio in 1,260 different ways.
