binge drinking and auto accidents
44% engaged binge drinking
37% drank moderately
9% abstain
17% accident/binge
9% accident/non-binge
what’s p(accident/abstain)
Answer:
We can solve this problem using the following steps:
1. **Calculate the probability of being in each group.**
The probability of being in the binge drinking group is 44%.
The probability of being in the moderate drinking group is 37%.
The probability of being in the abstain group is 9%.
2. **Calculate the probability of being in the accident group.**
The probability of being in the accident group is 17% + 9% = 26%.
3. **Calculate the probability of being in the abstain group and having an accident.**
The probability of being in the abstain group and having an accident is the probability of being in the abstain group multiplied by the probability of having an accident, given that you are in the abstain group.
The probability of being in the abstain group is 9%.
The probability of having an accident, given that you are in the abstain group, is the probability of being in the accident group and being in the abstain group, divided by the probability of being in the abstain group.
The probability of being in the accident group and being in the abstain group is 9%.
The probability of being in the abstain group is 9%.
Therefore, the probability of having an accident, given that you are in the abstain group, is 9% / 9% = 1.
4. **Calculate the probability of having an accident and being in the abstain group.**
The probability of having an accident and being in the abstain group is the probability of being in the abstain group and having an accident.
The probability of being in the abstain group is 9%.
The probability of having an accident, given that you are in the abstain group, is 1.
Therefore, the probability of having an accident and being in the abstain group is 9% * 1 = 9%.
**Answer:**
The probability of having an accident and being in the abstain group is 9%.

Between which two weeks did the water level change the most? Calculate the change.
Between Weeks 3 and 4, the water level varied the greatest.
To determine which two weeks had the greatest change in water level, we need to find the difference between each pair of consecutive weeks and identify the largest difference.
Here are the differences between consecutive weeks:
Week 1 to Week 2: (1 3/8) - (-1 1/4) = 2 5/8
Week 2 to Week 3: 2 1/2 - 1 3/8 = 1 1/8
Week 3 to Week 4: (-1 5/8) - 2 1/2 = -4 1/8
Week 4 to Week 5: (-1 3/4) - (-1 5/8) = -1/8
The largest difference is between Week 3 and Week 4, with a difference of 4 1/8 inches.
Therefore, the water level changed the most between Week 3 and Week 4.
Note that the differences are calculated by subtracting the water level of the earlier week from the water level of the later week.

a parallelogram has a base of 6 centimeters and a height of 10 centimeters. this parallelogram has the same area as a triangle with a height of 5 centimeters. what is the measure, in centi,of the base of the triangle?
The area of the parallelogram can be found using the formula A = base × height:
A = 6 cm × 10 cm
A = 60 cm²
The area of a triangle is given by the formula A = 1/2 × base × height. We know the height is 5 cm and the area is also 60 cm² (since it is equal to the parallelogram). So, we can solve for the base:
60 cm² = 1/2 × base × 5 cm
Dividing both sides by 1/2 × 5 cm gives:
base = 24 cm
Therefore, the base of the triangle is 24 centimeters.

∠A and ∠ � ∠B are vertical angles. If m ∠ � = ( 2 � − 2 ) ∘ ∠A=(2x−2) ∘ and m ∠ � = ( 3 � − 15 ) ∘ ∠B=(3x−15) ∘ , then find the value of x.
The calculated value of x if ∠A and ∠B are vertical angles is 13 degrees
How to find the value of x.From the question, we have the following parameters that can be used in our computation:
∠A = (2x − 2)
∠B = (3x − 15)
Since the ∠A and ∠B are vertical angles, then they are congruent angles

A graph of triangle T'O'W, the image of ΔTOW after a reflection in the y-axis is shown below.
The coordinates of ΔT'O'W are: T' (5, 6), O' (-1, 8), and W' (4, -2).
What is a reflection over the y-axis?In Mathematics and Geometry, a reflection over or across the y-axis is represented by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over or across the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.
Next, we would apply a reflection over or across the x-axis;
(x, y) → (-x, y)
T (-5, 6) → (-(-5), 6) = T' (5, 6)

The new vertices of the triangle after moving the triangle 5 units down, are A(1,-7), B(9,-7), and C(5,-3). So, correct option is B.
To determine the coordinates of the triangle after it is translated 5 units down, we need to subtract 5 from the y-coordinates of each vertex.
Let's start with vertex A(1,-2). If we subtract 5 from -2, we get -7. Therefore, the new coordinates of vertex A are (1,-7).
Next, let's look at vertex B(9,-2). Again, if we subtract 5 from -2, we get -7. So the new coordinates of vertex B are (9,-7).
Finally, let's consider vertex C(5,2). If we subtract 5 from 2, we get -3. So the new coordinates of vertex C are (5,-3).
In this case, we are moving the triangle 5 units down, which means that we are subtracting 5 from the y-coordinates of each vertex. This is a common transformation in geometry, and it's important to be familiar with it when working with shapes and figures in the Cartesian plane.
So, correct option is B.

You want the equation of the exponential curve h(x) = a·b^x when it goes through the points (0, 3) and (1, 6).
PointsWhen x=0, the equation is ...
h(0) = a·b^0 = a
We know that h(0) = 3, so a = 3.
When x=1, the equation is ...
h(1) = 3·b^1 = 3b

Find the total cost for the month in dollars. The federal tax is 3%. Use the figure below.
Monthly phone service plan is $52.00. Four lines and 3,487 minutes are used.
Answer:
The total cost per month is $190.76 to the nearest cent.
Step-by-step explanation:
From the given table, the monthly service plan costing $52.00 is:
Monthly Service Plan = $52.00Number of included minutes per month = 2,000 minutesCost per additional line per month = $21.99Overage per minute rate = $0.06The base calling plan includes two lines.
Therefore, for 4 lines, we will need to pay for 2 additional lines per month:
⇒ $21.99 × 2 = $43.98 per month
If 3,487 minutes are used per month, then the overage of minutes is:
⇒ 3487 - 2000 = 1487 minutes per month
As the overage rate is $0.06 per minute, then the cost of the additional minutes is:
⇒ 1487 × $0.06 = $89.22 per month
Therefore, the total cost per month before tax is:
⇒ $52.00 + $43.98 + $89.22 = $185.20
To apply the federal tax of 3%, multiply the total cost by 1.03:
⇒ $185.20 × 1.03 = $190.756 = $190.76 (nearest cent)
Therefore, the total cost per month is $190.76 to the nearest cent.

the salaries of engineers at a computer company are normally distributed with mean $83,422 and standard deviation $8,278
The probability of observing an income between $70,000 and $90,000 for engineers at this computer company is 0.6217, or about 62.17%.
To solve this problem, we need to standardize the given income range using the standard normal distribution, which has a mean of 0 and a standard deviation of 1. We can do this by using the formula:
z = (x - μ) / σ
where x is the income, μ is the mean income, and σ is the standard deviation.
For the lower bound of $70,000, we have:
z₁ = (70,000 - 83,422) / 8,278 = -1.62
For the upper bound of $90,000, we have:
z₂ = (90,000 - 83,422) / 8,278 = 0.79
We can now find the probability of observing an income between $70,000 and $90,000 by calculating the area under the standard normal curve between z₁ and z₂.
We can use a standard normal distribution table or a calculator to find this probability, which turns out to be approximately 0.6217. This means that about 62.17% of engineers at this company earn an income within this range.
