Which equation is equivalent to the given equation?
–8(x + 13) = 2(x - 7) + 4x
Answer: Is C
-8x-104=6x-14
Step-by-step explanation: I got the question right
Answer: -8x - 104= 6x - 14
Step-by-step explanation:
-8(x+13) =2(x-7) + 4x
-8x - 104 = 2X - 14 + 4x
-8x - 104 = 6x - 14
For a continuous random variable X, P(23 ≤ X ≤ 66) = 0.25 and P(X > 66) = 0.14. Calculate the following probabilities. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)
Complete question :
For a continuous random variable X, P(23 ≤ X ≤ 66) = 0.25 and P(X > 66) = 0.14. Calculate the following probabilities. (Leave no cells blank - be certain to enter "0" wherever required. Round your answers to 2 decimal places.)
a. P(X < 66)
b. P(X < 23)
c. P(X = 66)
Answer:
P(X < 66) = 0.86
P(X < 23) = 0.61
P(X = 66) = 0
Step-by-step explanation:
Given that:
X, P(23 ≤ X ≤ 66) = 0.25 and
P(X > 66) = 0.14 ;
Recall:
P(x ≤ a) + p(x ≥ a) = 1
Then ; P(X < 0.66) = 1 - 0.14 = 0.86
Hence,
P(X < 0.66) = 0.86
P(23 ≤ X ≤ 66) = 0.25
P(X < 66) = 0.86
Hence,
P(X < 23) = 0.86 - 0.25 = 0.61
Probability that a continuous random variable is exactly equal to a particular number equals 0
Hence,
P(X = 66) = 0
i already know the answer can someone explain or show me how to do it on a numberline
Answer:
I'm not sure what the question is but an example question could be
"Take 5 away from 3."
For this you would go to three on the number line and then move left five gaps. You would land on -2
another example: "Add 4 to -3."
For this, you would go to -3 on the number line, and then move right 4 times. you would land on 1.
Answer:
4.5
Step-by-step explanation:
just move 1 1/2 steps to the left

In the inequality -2|2x-3|>-12, what is the range for x?
9514 1404 393
Answer:
-3/2 < x < 9/2
Step-by-step explanation:
You can divide the inequality by -2, then rewrite as a compound inequality:
|2x -3| < 6
-6 < 2x -3 < 6
Add 3 and divide by 2:
-3 < 2x < 9
-3/2 < x < 9/2

3) 0.354535 ; 100x ≈ 35.35 ; x ≈ 0.35 ; 35.35-.35= 35; 100x-x = 99x ; x = 35/99
4) 0.242424 ; 100x ≈ 24.24 ; x ≈ 0.24 ; 24.24-.24 = 24 ; 100x-x = 99x ; x = 24/99
5) 0.393939 ; 100x ≈ 39.39 ; x ≈ 0.39 ; 24.24-.24 = 24 ; 100x-x = 99x ; x = 39/99

Can somebody pls answer these three questions ASAPPPP!!!!
Answer:
1) x = 3/2 2) x = 6 3) x = 3
Step-by-step explanation:
For Number 1:
4(x+8)−4=34
Step 1: Simplify both sides of the equation.
4(x+8)−4=34
(4)(x)+(4)(8)+−4=34(Distribute)
4x+32+−4=34
(4x)+(32+−4)=34(Combine Like Terms)
4x+28=34
Step 2: Subtract 28 from both sides.
4x=6
Step 3: Divide both sides by 4.
4x/4 = 6/4
x = 3/2
For Number 2:
2/3(9+x)=−5(4−x)
Step 1: Simplify both sides of the equation.
6 + 2/3x = −20+5x
Step 2: Subtract 5x from both sides.
−13 /3 x+6=−20
Step 3: Subtract 6 from both sides.
-13/3x = -26
Step 4: Multiply both sides by 3/(-13)
x = 6
For Number 3:
−3(x+4)+15=6−4x
Step 1: Simplify both sides of the equation.
−3(x+4)+15=6−4x
(−3)(x)+(−3)(4)+15=6+−4x(Distribute)
−3x+−12+15=6+−4x
(−3x)+(−12+15)=−4x+6(Combine Like Terms)
−3x+3=−4x+6
−3x+3=−4x+6
Step 2: Add 4x to both sides.
−3x+3+4x=−4x+6+4x
x+3=6
Step 3: Subtract 3 from both sides.
x+3−3=6−3
x = 3

The sidewalks on both sides of Peach St. are parallel. One sidewalk can be modeled by the equation 2x-y=-1. Which equation could model the other sidewalk?
a. 2x+y=8
b.y-1=2(x-3)
c. y-1=-2(x-3)
d.y=-1/2x+3
Answer: B. y-1=2(x-3)
Step-by-step explanation:
First subtract both sides by 2x so it becomes -y=-2x-1
Second divide both sides by -1 so it becomes y=2x+1
After that to get it in the form they want it subtract 1 from both sides so that it becomes y-1=2x

Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89z. Assume that the conditions for inference were met.
Complete Question
Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89 z. Assume that the conditions for inference were met.calculate the p-value for Ellie's significance test
Answer:
The p-value is [tex]p-value = 0.0588[/tex]
Step-by-step explanation:
From the question we are told that
The percentage of senior citizens is p = 0.10
The sample size is [tex]n = 225[/tex]
The sample proportion is [tex]\^{p} = 0.14[/tex]
The test statistics is [tex] z \approx = 1.89[/tex]
The null hypothesis is [tex]H_o : p = 0.10[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.10[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 1.89 )[/tex]
From the z-table
[tex]P(Z > 1.89 ) = 0.029379[/tex]
=> [tex]p-value = 2 * 0.029379[/tex]
=> [tex]p-value = 0.0588[/tex]

5X+17=7 PLEASE HELP FAST
Answer:
x = -2Step-by-step explanation:
5X + 17 = 7
subtract 17 each side
5x + 17 - 17 = 7 - 17
divide 5 both sides
5x = -10
5x/5 = -10/5
x = -2
The solution of expression is,
⇒ x = - 2
We have to given that;
The expression is,
⇒ 5x + 17 = 7
Now, We can simplify as;
⇒ 5x + 17 = 7
Subtract 17 both side,
⇒ 5x = 7 - 17
⇒ 5x =- 10
Divide by 5;
⇒ x = - 10/5
⇒ x = - 2
Thus, The solution of expression is,
⇒ x = - 2

What is an inverse function?First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.
We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.
We know a function f(x) has its inverse g(x) if and only if f(x) is a one-to-one function.
From the given statements the only true statement is, g(x) is a function because f(x) is one-to-one.
