The group wants to pick up trash along a 2 mile road.
They divide the length of the road.
To find the length of the road that each volunteer picks up trash, we have to divide the length of the road by the number of volunteers.
Let us do that for the 3 options:
a. 8 volunteers
[tex]\frac{2}{8}\text{ = 0.25 mile per volunteer}[/tex]b. 10 volunteers
[tex]\frac{2}{10}\text{ = 0.2 mile per volunteer}[/tex]c. 25 volunteers
[tex]\frac{2}{25}\text{ = 0.08 mile per volunteer}[/tex]d. 36 volunteers
[tex]\frac{2}{36}=\text{ 0.05 mile per volunteer}[/tex]In many epidemics, the cumulative number of cases grows exponentially, at least over a limited time. A recent example is the spread of the Influenza A (HIN1) virus, commonly called thwhich affected Mexico and the United States especially. On April 24, 2009, there were seven cumulative cases of swine flu in the United States reported to the World Health Organization.next two weeks, the cumulative number of cases in theUnited States increased by about 40% each day. If this growth rate had continued, what would have been the cumulative numberthe United States reported 20 days after April 24? (Round your answer to the nearest whole number.)cases
If the growth is exponential, it follows the formula:

A coin is flipped and a normal 6 sided die is rolled find the probability of getting a head on the coin and a number greater than 4 on the die
Answer:
[tex]P(C\text{ and D)=}\frac{1}{6}[/tex]Step-by-step explanation:
Probability is represented by the following equation:
[tex]P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of favorable outcomes}}[/tex]Therefore, for this situation:
[tex]\begin{gathered} P(\text{Coin)}=\frac{1}{2} \\ P(\text{Die)}=\frac{2}{6} \end{gathered}[/tex]Since the probability of two events occurring together but independents is represented by the multiplication of the probabilities of the events:

The results of a random selection of 30 of the 450 marbles are shown in the table above. Based on this one sample , which of the following is the best estimate of the number of red marbles in the jar.
Our problem involves probability. One thing that we must take note of probabilities is that the higher the number of a certain thing is, the higher probability of it happening. For example, in a lottery the higher the number of of tickets that you will buy the higher the chances of you winning the lottery.
Now let us talk about the basic formula of the probability of an event happening. The probabilty of an event happening is just the ratio of the number of a certain outcome to the total number of outcomes. Presenting it as an equation we get:
[tex]P(A)=\frac{\text{Number of a certain Outcome}}{\text{Total number of Outcome}}[/tex]4. Which expression is equivalent to 9-^2•9^-35. The expression 2^3•4^26. Are (10^-3)^2 and (10^-2)3(NUMBER 4 & 5 & 6)
Answer

Question 6
Option B is correct.
Yes, both expressions are equal to 10⁻⁶
Question 7
3⁰ + 3⁻² = 1 (1/9) = (10/9)
Explanation
To answer these questions, we will use the laws of indices.
- When a variable carries a power and is raised to an extra power, the answer is the variable carrying the product of these two powers.
- When a variable is raised to the power of a negative number, this is the same as 1 over that variable raised to the positive value of that power
- When the same variable, carrying different powers are multiplied with each other, then, the result is that same variable raised to the power of the sum of the two powers from before multiplication.
- When any number or variable is raised to the power of 0, the answer is 1.

To know the answer to this, we will solve the two expressions
[tex]\begin{gathered} (10^{-3})^2=10^{-3\times2}=10^{-6} \\ (10^{-2})^3=10^{-2\times3}=10^{-6} \end{gathered}[/tex]We can see that both expressions are equal to 10⁻⁶
Question 7
3⁰ + 3⁻²
3⁰ = 1
3⁻² = (1/3²) = (1/9)
3⁰ + 3⁻² = 1 + (1/9) = 1 (1/9) = (10/9)

An accident investigator measured the skid marks of one of the vehicles involved in an accident. Thelength of the skid marks was 250 feet. Use the formula s=1(24d) (?"s equals square root of 24*d") tofind the speed of the vehicle before the brakes were applied. Round your answer to the nearesttenth. The units are mi/hr
Given the equation:
[tex]s=\sqrt[]{24d}[/tex]Where d is the distance and (s) is the speed
We will find the value of (s) when d = 250 feet
So, substitute with d = 250, and solve for (s)
[tex]s=\sqrt[]{24\cdot250}=\sqrt[]{6000}\approx77.459667[/tex]Rounding to the nearest tenth
so, the answer will be:
Speed = s = 77.5 mi/hr

If a triangle ABC is at: A = ( 3, 6 ) B = ( 1, 7 ) C = ( - 2, - 4 ) and if it is translated right 6 and down 3, find the new point B'.
Solution: B': (7,4)
As we have a triangle, we move each point according to the statement of exercise. We have B = (1,7). As we have to move right 6, that would be increasing X value. So, we have:
X initial: 1. We move right 6, X final= 1+6; X final=7
We down 3, so that would be decreasing Y value.
Y initial= 7. We move down 3, Y final=7-3; Y final=4
According to that, the new point B' would be= (7,4)

Answer
Option A is correct.
1 is the only option provided that satisfies the given inequality.
Explanation
We are asked to pick the right option that satisfies the given inequality.
To do this, we will just solve the given inequality equation
8x + 2 < 18
Subtract 2 from both sides
8x + 2 < 18
8x + 2 - 2 < 18 - 2
8x < 16
Divide both sides by 8
(8x/8) < (16/8)
x < 2
So, the solution of this will be the numbers less than 2.
Of the options, we can see that only 1 is less than 2 and that is the answer for this question.

The human body needs about 50 grams of protein daily. A hamburger contains about 20 grams of protein. What percent of the daily needs is the protein in the hamburger?
To answer this question, we can proceed as follows:
1. We have that the total of protein the human body needs daily is 50 grams.
2. A hamburger contains about 20 grams of protein.
Then, to find the asked percent, we can proceed as follows:
[tex]\begin{gathered} \frac{20}{50}\cdot100\%=\frac{2}{5}\cdot100\%=\frac{2\cdot100\%}{5}=2\cdot\frac{100\%}{5}=2\cdot20\%=40\% \\ \end{gathered}[/tex]Therefore, the hamburger has 40% of the protein we need daily.

What is the domain of the function?Type the domain using interval notation example : (#,#]
The domain of the function is described as a set of values of x where the function exists. Based on the plot given, the permissible values of x start at -1 and the function will continue to exist for any values of x greater than or equal to -1 until infinity. Hence, the domain of this function using interval notation is [-1, ∞). Note that -1 is an acceptable value of x based on the plot since the point where the plot starts (at x = -1) is shaded black, hence, we use a bracket sign at the left-hand side of the notation.
