Joel wants to determine the solution to 0.5^x+4 ≤ 2. He first graphs 0.5^x+4-2 ≤ y as shown. Joel then graphs y ≤ 2 on the same coordinate plane and claims that the solution set to 0.5^x+4 ≤ 2 is the interval [6, infinity), because the overlapping region matches this interval. which statement describes Joel's error?

at a hot dog stand they serve regular and footlong hot dogs at a ratio of 5 to 3 based on this ratio how many footlongs hot dogs will be served there is a total of 120 hot dogs served. A. 45 footlong hot dogs, B. 75 footlong hot dogs, C. 72 footlong hot dogs
Answers
Answer:
45
Step-by-step explanation:
Ratio is 5:3
So total ratio "parts" is 5 + 3 = 8
In total there are 120 dogs served, so each part is:
120/8 = 15 dogs
Since, footlong hot dogs are "3" parts, and each part is 15 dogs, there will be:
3 * 15 = 45 footlong hotdogs
Answer:
45

a printing service charges a set up fee of 11.00 for each order and 10 cents more for each copy . the totsl cost, C (in dollars), for an order of x copies is given by the following . C= 11.00+ 0.10x
What is the total cost for an order of 20 copies ?
Answers
Answer:
$13.00
Step-by-step explanation:
First, you plug in your x value for copies into the equation C=11.00+0.10x to get a starting equation of x=11.00+0.10(20). Since 0.10 is equivalent to 1/10, it's easy to compute (1/10)(20)=2. You now have an equation of C=11.00+2.00 to get C=13.00. Therefore, the total cost for an order of 20 copies is 13 dollars (and 0 cents).

Step-by-step explanation:
The expression (–4a² – 3b) + (–2ab – a² + b²) + (–b² + 6ab) is equivalent to the expression (–5a² + 4ab – 3b). Then the correct option is D.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
The polynomial expression are given below.
(–4a² – 3b) + (–2ab – a² + b²) + (–b² + 6ab)
On simplifying, we have
– 5a² + 4ab – 3b
Then the correct option is D.

A survey found that 31% of all teens buy soda (pop) at least once each week. Seven teens are randomly selected. The random variable represents the number of teens who buy soda (pop) at least once each week. What is the value of n
Answers
Answer:
The value of n is 7.
Step-by-step explanation:
For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.

An inequality in one-variable is shown below.
2x + 4 = 14
Which problem situation could represent the inequality?
Answers
Answer:
You wrote:
2*x + 4 = 14
This is not an inequality, so i guess that you wanted to write something like:
2*x + 4 ≥ 14
Now, this means that the left equation is always equal to or larger than 14.
Now, which type of problem this may represent?
Well, 2*x + 4 should represent something that is larger than 14, only that.
Then we can write something like:
"You have 4 dinosaur toys, and in the toy store near your house, they sell packs of 2 dinosaur toys. If you want to have at least 14 dinosaur toys, how many packs can you buy?"
Now x represents the number of packs that you buy.
2*x is the number of dinosaurs in these packs
2*x + 4 is the total number of dinosaurs that you have, when you also count the ones that you previously had.
2*x + 4 ≥ 14
Is the inequality that represents the problem.
