Break it up into two trapezoids as shown

area = trap1 + trap2

      = 2 *   (7+3) / 2   + 3 *  ( 7 + 3) / 2 = 10 + 15 = 25 units^2

Answer:

B. Yes, because 6 + 11 ≠ 13.

Step-by-step explanation: So for this one, you have to add two numbers and if the third number is bigger it is a possible construct but if it less than the third number than it is not a possible construct. So 6+ 11 = 17 (its good so far) 11 + 13 = 24(its good so far) 13 + 6 = 19( its good so far) everything checks out that means B is right. And also it is not D because that is saying 6 + 11 is less than 13 which is wrong. Hope this helps someone :)

Step-by-step explanation:

What you are testing is a distribution of means, because you have a sample of eleven individuals (N=11), a population mean, and the population variance. Basically, the problem is asking: what is the likelihood that the sample mean (153.45 lbs) could have been obtained from a population where (M=149) if the null hypothesis is true?

p1: 15 year old boys with a mean weight of 153.45 lbs from City "Unknown".

p2: 15 year old boys with a mean weight of 149.00 lbs from the population.

H1: The sample of boys from City "Unknown" was not drawn from a population where the average weight of 15 year old boys = 149lbs.

H0: The sample of boys from City "Unknown" was drawn from a population where the average weight of 15 year old boys = 149lbs.

Mean = 149 [μM = μ = 149]

Variance = 16.2squared/11 = 262.44/11 = 23.86 [σM2 = σ2/N]

Standard Deviation = 4.88 [σM = √σM2 = √(σ2/N)]

Shape = normal

Using .01 level of significance for a two-tailed test, the cutoff sample score is +/- 2.575

Z = (M-µ) / σM = (153.45 - 149) / 4.88 = .91

.91 < 2.575

σM or the Standard Error of the Mean is 4.88 so...

for 99% confidence interval,

lower limit = 153.45 + (-2.575)(4.88) = 140.88

upper limit = 153.45 + (2.575)(4.88) = 166.02

the 99% confidence interval = 140.88 — 166.02 (lbs)

the population mean (µ=149.00) is included in the interval, which confirms results of Z test.

Conclusion: retain null, there is <.01 probability that the sample from City "Unknown" was drawn from a population where the mean weight is NOT = 149.00lbs.

The step Hazel made the mistake in was step 2. She made the mistake of subtracting 3t-3. You cannot do this because they are not like terms. To be like terms, the second 3 would have to have a t on it as well.

Step-by-step explanation:

The equation in slope intercept form of the line that passes through the points (-4, 2) and (12, 6) is y = 0.25x + 3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The points are given as

(-4, 2) and (12, 6)

Calculate the slope of the points using

m = (y2 - y1)/(x2 - x1)

So, we have

m = (6 - 2)/(12 + 4)

Evaluate

m = 0.25

The equation is then calculated as

y = m(x - x1) + y1

Where

(x1, y1) = (-4, 2)

So, we have

y = 0.25(x + 4) + 2

Expand

y = 0.25x + 1 + 2

Evaluate

y = 0.25x + 3

Hence, the equation in slope intercept form of the line that passes through the points (-4, 2) and (12, 6) is y = 0.25x + 3

To calculate the cost of direct labor for the surgeon per patient, we need to determine the total labor cost for a day and then divide it by the number of patients served.

First, let's calculate the total labor cost for a 10-hour day. The surgeon takes 120 minutes (2 hours) to serve one patient, so in 10 hours, they can serve:

10 hours / 2 hours per patient = 5 patients

The wage rate for the surgeon is $250 per hour, so the total labor cost for a 10-hour day is:

10 hours/day $250/hour = $2500

Now, let's calculate the cost of direct labor per patient:

Total labor cost / Number of patients = $2500 / 5 patients = $500 per patient

Therefore, the cost of direct labor for the surgeon expressed in $ per patient is $500.

None of the options provided match the calculated value of $500, so none of the given options (A, B, C, D) are correct.

The slope between the two points given (0,0) and (4,2) is 2.

A line's slope is a measure of its steepness as well as direction.

The slope of a line is defined as the variation in y coordinate in relation to a modification in x coordinate.

m = Δy/Δx

where, m is the slope

And, tan θ = Δy/Δx

This tan is also recognized as the slope of the line.

The slope of a line can be calculated using only two points on a straight line. Then with coordinates of two points, we could use slope of line formula.

Now, as per the given question;

Consider their coordinates;

P1 = (x₁, y₁)

P2 = (x₂, y₂)

Then slope will become;

Slope = m = tan θ = (y₂ - y₁)/(x₂ - x₁)

See the values given in the question;

(x₁, y₁) = (0,0) and,

(x₂, y₂) = (4,2)

Put the values in the formula of the slope;

Slope = m = (4 - 0)/(2 - 0)

m = 4/2

m = 2

Therefore, the slope of the line passing from the two given points is 2.

While personality testing can provide insights into a candidate's traits, its effectiveness in predicting job performance is not universally agreed upon by experts. It should be used as part of a broader assessment strategy, with consideration given to legal and ethical considerations.

Personality testing has been a topic of discussion in the hiring process. Experts have come to various conclusions regarding its use. Here are some key points to consider:

1. Validity and reliability: One concern is whether personality tests accurately measure traits relevant to job performance. Experts have found mixed results, with some tests demonstrating good validity and reliability, while others may lack these qualities.

2. Legal considerations: Experts also highlight the importance of complying with legal standards when using personality tests. These tests should not discriminate against protected groups or violate any laws related to equal opportunity employment.

3. Complementing other methods: It is generally recommended to use personality tests as part of a comprehensive hiring process, alongside other methods such as interviews and work samples. Combining multiple assessment tools can provide a more holistic view of a candidate's suitability for a role.

4. Limited predictive power: Personality tests should not be solely relied upon as a predictor of job performance. Other factors, such as skills, experience, and work environment, also play significant roles.

5. Ethical considerations: Experts emphasize the need for transparency and informed consent when using personality tests. Candidates should understand the purpose and implications of the test and have the option to decline participation.In conclusion, while personality testing can provide insights into a candidate's traits, its effectiveness in predicting job performance is not universally agreed upon by experts.

Answer:

0.68

Step-by-step explanation:

According To the Question,

Let, H ⇒ "heavy traffic" & T ⇒  "get there on time".

Then, "half of the time there is heavy traffic" ⇔ P(H)=0.5.

Now, you are given that there is heavy traffic, so We need to find P(T I H).

 P(T l H) = P(H and T) / P(T)

P(T l H) = 0.34/0.5 ⇒ 0.68

These are the solutions to the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0.

To solve the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0, we need to simplify and rearrange the equation to its standard form and then solve for p.

Combining like terms, the equation becomes:

3p^2 - 10p + 5 = 0

Now, we can use the quadratic formula to solve for p. The quadratic formula states:

p = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 3, b = -10, and c = 5. Substituting these values into the quadratic formula, we have:

p = (-(-10) ± √((-10)^2 - 4 * 3 * 5)) / (2 * 3)

Simplifying further:

p = (10 ± √(100 - 60)) / 6

p = (10 ± √40) / 6

p = (10 ± 2√10) / 6

Now, we can simplify and find the two possible values of p:

p₁ = (10 + 2√10) / 6

p₂ = (10 - 2√10) / 6

These are the solutions to the quadratic equation p^2 + 2p^2 - 5 * 2p + 5 = 0.

In simplified form, the solutions are:

p₁ = (5 + √10) / 3

p₂ = (5 - √10) / 3

The upper left corner with an x-value of 10 and a y-value of 20 to the given scatterplot would likely decrease the value of the correlation coefficient, r.

The correlation coefficient, r, measures the strength and direction of the linear relationship between two variables. It ranges from -1 (perfect negative correlation) to 1 (perfect positive correlation), with 0 indicating no correlation. In a scatterplot, points that are closer to forming a straight line indicate a stronger linear relationship, while points that are more scattered indicate a weaker linear relationship.

In the given scatterplot, adding a point in the upper left corner with an x-value of 10 and a y-value of 20 would likely introduce an outlier that deviates from the overall pattern of the data. This outlier would be located far away from the other points, potentially causing the scatterplot to become more scattered and less linear. As a result, the linear relationship between the two variables, as measured by the correlation coefficient, r, would likely decrease. This is because the outlier would have a disproportionate influence on the calculation of the correlation coefficient, pulling it closer to 0 or even changing the direction of the correlation, if the outlier introduces a different pattern to the data.

Therefore, adding a point in the upper left corner with an x-value of 10 and a y-value of 20 to the given scatterplot would likely decrease the value of the correlation coefficient, r.

Solving with the quadratic formula

\(3x^2-2x=5\)

subtract 5 from both sides

\(3x^2-2x-5=5-5\)

Simplify

\(3x^2-2x-5=0\)

For a quadratic equation of the form ax²+bx+c=0

\(x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\)

For a = 3, b = -2, c = -5

\(x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:3\left(-5\right)}}{2\cdot \:3}\)

\(x_{1,\:2}=\frac{-\left(-2\right)\pm \:8}{2\cdot \:3}\)

Separate the solutions

\(x_1=\frac{-\left(-2\right)+8}{2\cdot \:3},\:x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}\)
