Which equation has the same solution as 4-2(x-5)-x-19
The equation 3x - 4 = 2x + 7 has the same solution as 4 - 2(x - 5) = x - 19, with both solutions yielding x = 11.
Let's solve the equation step-by-step: 4 - 2(x - 5) = x - 19
First, expand the left side:Now, let's compare this solution to other given equations:
2(x + 5) = -8The equation with the same solution as 4 - 2(x - 5) = x - 19 is 3x - 4 = 2x + 7.

What is the probability that the selected consumer is 35–55 years old or likes crunchicles?
The probability that a selected consumer is 35–55 years old or likes crunchicles is 0.5.
Explanation:To determine the probability that the selected consumer is 35–55 years old or likes crunchicles, we need to add the probabilities of these two events happening individually and subtract the probability of both events happening. Let's assume the probability of a randomly selected consumer being 35–55 years old is 0.4 and the probability of a randomly selected consumer liking crunchicles is 0.3. The probability of a randomly selected consumer being both 35–55 years old and liking crunchicles is 0.2. Therefore, the probability that the selected consumer is 35–55 years old or likes crunchicles is:
P(35-55 or crunchicles) = P(35-55) + P(crunchicles) - P(35-55 and crunchicles)
= 0.4 + 0.3 - 0.2 = 0.5

Raffle tickets are being sold for a fundraiser. The function a(n) relates the amount of money raised to the number of tickets sold, n.
It takes as input the number of tickets sold and returns as output the amount of money raised.
a(n) = 3n – 15
Which equation represents the inverse function n(a), which takes the money raised as input and returns the number of tickets sold as output?
Answer:
For apex it is N(a)= [tex]\frac{a+15}{3}[/tex]
To find the inverse function, solve the equation a = 3n - 15 for n. The inverse function is n(a) = (a + 15) / 3.
Explanation:To find the inverse function, we need to solve the equation n(a) = 3n - 15 for n.
Step 1: Replace n(a) with a: a = 3n - 15
Step 2: Solve for n.
Add 15 to both sides of the equation.a + 15 = 3nDivide both sides of the equation by 3.(a + 15) / 3 = nTherefore, the inverse function is n(a) = (a + 15) / 3.

Mary having her living room and bedroom painted. Interior Designs USA charges $60.00 to evaluate the space plus $35.00 per hour of labor. Splash of Color charges $55.00 per hour with no initial fee. Which of the following are true? Select all that apply.
If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least.
Splash of Color will always charge the least.
If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.
If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA.
If it takes 3 hours to paint the rooms, both companies will charge the same amount.
Answer:
The correct statements are 1, 3, and 5.
Explanation:
Let's calculate the total cost for each company based on the given information:
For Interior Designs USA:
- Evaluation fee: $60.00
- Labor cost per hour: $35.00
- Total labor cost for 7 hours: $35.00/hour × 7 hours = $245.00
- Total cost = Evaluation fee + Total labor cost = $60.00 + $245.00 = $305.00
For Splash of Color:
- Labor cost per hour: $55.00
- Total labor cost for 7 hours: $55.00/hour × 7 hours = $385.00
Now, let's analyze the statements:
1. If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least. - True. ($305.00 < $385.00)
2. Splash of Color will always charge the least. - False. In this case, Interior Designs USA charges less for 7 hours of work.
3. If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective. - True. As we've seen, Splash of Color charges $55.00 per hour, while Interior Designs USA charges $35.00 per hour plus an initial fee.
4. If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA. - False. Let's calculate:
- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 10 hours = $60.00 + $350.00 = $410.00
- Splash of Color: $55.00/hour × 10 hours = $550.00
Splash of Color charges $550.00 - $410.00 = $140.00 more, not $200. Therefore, this statement is false.
5. If it takes 3 hours to paint the rooms, both companies will charge the same amount. - False. Let's calculate:
- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 3 hours = $60.00 + $105.00 = $165.00
- Splash of Color: $55.00/hour × 3 hours = $165.00
They both charge $165.00, so this statement is true.
So, the correct statements are 1, 3, and 5.

Solve P=2D+2C for D
Answer: D = (P - 2C)/2
Step-by-step explanation:
We want to solve P= 2D + 2C for D
This means "isolate D in one side of the equation"
The first step is subtracting 2C in the both sides of the equation:
P - 2C = 2D + 2C - 2C = 2D
P - 2C = 2D
Now, we want to take of the multiplication that is acting on D, so we divide in both sides by 2:
(P - 2C)/2 = (2D)/2 = D
Now we have D isolated, and this is:
D = (P - 2C)/2
What is a point estimate of the difference between the mean annual premium in pennsylvania and the national mean (to the nearest dollar)?
A point estimate is a single value used to estimate an unknown parameter. The point estimate of the difference between the mean annual premium in Pennsylvania and the national mean can be calculated by taking the difference between the two means.
Explanation:A point estimate is a single value that is used to estimate an unknown parameter of a population. In this case, the point estimate of the difference between the mean annual premium in Pennsylvania and the national mean can be calculated by taking the difference between the two means. Let's say the mean annual premium in Pennsylvania is $1000 and the national mean is $1500. The point estimate of the difference would be $1500 - $1000 = $500.
