Answer:

acute

Step-by-step explanation:

this is an acute triangle because all angles are less than 90 degrees

it is not obtuse because no angle is over 90 degrees

it is not equiangular because the angles are not equal to each other

and it is not right because there is no right angle

Acute

Triangles can be classified by the size of their angles.

Angle Classification

Angles can be classified into 3 sizes: acute, right, and obtuse.

Triangle Classification

Triangles are classified by their largest angle. If the largest angle is obtuse, then it is an obtuse triangle. If there is a right angle, then it is a right triangle. If the largest angle is an acute angle, then it is an acute triangle. Finally, there is one special classification that technical falls under acute angles. If all of the angles are equal (meaning they are all 60°), then it is an equiangular triangle.

The triangle in the picture has 3 angles that are all under 90°. The largest angle is 76°. Since this is an acute angle, it is an acute triangle.

By comparing the responses across the three groups, the researcher can identify potential variations in opinions based on educational background. This information can provide valuable insights into how different types of schooling may shape perspectives on civic policies like curfews.

That's an interesting research approach!  By gathering opinions from different groups of children, specifically home-schooled, private school attendees, and public school attendees, the researcher can gain insights into how various educational backgrounds might influence their opinions on the new town curfew.

Collecting a simple random sample from each group ensures that every child within the respective groups has an equal chance of being selected for the survey. This helps in minimizing bias and increasing the generalizability of the findings to the larger population of home-schooled, private school, and public school children.

Once the samples are obtained, the researcher can administer a survey or questionnaire to collect the children's opinions on the new town curfew. The survey may include questions related to their awareness of the curfew, their understanding of its purpose, and their personal opinions on whether they support or oppose it.

Answer:

she is wrong, offer 2 results in lower interests

Step-by-step explanation:

total amount paid if offer 1 is accepted:

$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40

she will pay $365.40 in interests

total amount paid if offer 2 is accepted:

($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363

she will pay $363 in interests

Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

Systematic random sampling is the sampling method is the auditor using for each salesperson.

Sampling techniques in a statistical study refer to how participants are chosen from the population to participate in the study. If a sample isn't chosen at random, it will likely be skewed in some way, and the results might not be generalizable.

Given,

The sales force for a publishing company is constantly on the road trying to sell books. as a result, each salesperson accumulates many travel-related expenses that he or she charges to a company-issued credit card. to prevent fraud, management hires an outside company to audit a sample of these expenses. for each salesperson, the auditor prints out the credit card statements for the entire year, randomly chooses one of the first 20 expenses to examine, and then examines every 20th expense from that point on.

Yes, they do form a triangle. This is because the sum of any two side lengths must be greater than the third side length for a triangle to be formed. In this case, 4 + 5 is greater than 10.

Yes, these three side lengths do form a triangle. This is because a triangle is a three-sided shape with three straight sides, and for a triangle to be formed, the sum of any two side lengths must be greater than the third side length. In this case, the sum of 4 and 5 is greater than 10, thus fulfilling the criteria needed to form a triangle. Furthermore, the triangle formed by these side lengths is a scalene triangle, which is a triangle with three unequal sides. This is because 4, 5 and 10 are all unequal lengths, therefore the triangle formed is scalene. Additionally, the triangle formed will also be acute, as all three angles must be less than 90 degrees for a triangle to be classified as acute. Thus, the triangle formed by the side lengths 4, 5 and 10 is an acute scalene triangle.

Step-by-step explanation:

its not that hard

The function is concave up for  x < 1 and concave down for x > 1 because the second derivative is positive for x < 1 and negative for x > 1. As a result, the critical point at x  < 1 is a relative maximum.

A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is common to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. A function is an equation that depicts the connection between an input x and an output y, with precisely one output for each input. Another name for input is domain, while another one for output is range.

Here,

The derivative of the function f(x) can be found by taking the derivative of the expression e^(-x) (x^2 + 2x) using the product rule:

f'(x) = -e^(-x) (x^2 + 2x) + e^(-x) (2x + 2) = 2e^(-x) - 2xe^(-x) (x + 1)

Setting f'(x) equal to zero and solving for x gives us the critical points:

0 = 2e^(-x) - 2xe^(-x).(x + 1)

2xe^(-x).(x + 1) = 2e^(-x)

x(x + 1) = e^x

x^2 + x - e^x = 0

Next, we determine the concavity of the function at the critical points by analyzing the second derivative of the function:

f''(x) = 2e^(-x) + 2xe^(-x) + 2xe^(-x).(x + 1) - 2e^(-x).(x + 1)

= 2e^(-x).(1 - x)

Since the second derivative is positive for x < 1 and negative for x > 1, the function is concave up for x < 1 and concave down for x > 1. Thus, the critical point at x < 1 corresponds to a relative maximum.

Step-by-step explanation:

In this scenario, the researcher is interested in studying the population of men in a particular village. This group of men represents the population of interest for the study. The relevant population data would consist of the height measurements of all the men in the village. The population parameter of interest to the researcher is the average height of the men in the village.

By determining this population parameter, the researcher can gain insight into the central tendency of the height distribution for men in the village. This information can be used to make informed decisions or draw conclusions about the population of interest.

To obtain an accurate estimate of the population parameter, the researcher would need to collect a representative sample of height measurements from the men in the village and calculate the sample mean. The sample mean could then be used to estimate the population parameter with a certain degree of confidence.

Answer:

The actual area of the town is 14 miles.

Step-by-step explanation:

Since you know that the scale is 1 inch:4 miles and that the map shows a town with an area of 3.5 inches, you can expressed this as follows:

Scale: 1 inch:4 miles

map area: 3.5 inches

If the actual area is x, you can say that:

3.5:x=1:4

This would be:

\(\frac{3.5}{x}=\frac{1}{4}\)

Now, you can solve for x:

x=(3.5*4)/1

x=14

According to this, the answer is that the actual area of the town is 14 miles.

The exact value of sinθ in simplest radical form is sinθ = 1.

The terminal side of an angle in standard position is a line passing through the point (x,y).

To find the exact value of sinθ, use the trigonometric identity sinθ = y/r, where r is the distance or length of the line segment from the origin

r = √(x² + y²)

Given the point (-20, 21), the value of sinθ is 21/√(20² + 21²).

Simplifying, 21/√(441), sinθ = 21/21 = 1.

Therefore, the exact value of sinθ in simplest radical form is sinθ = 1.

Elvira's walking speed is 9.4 miles per hour, and Aletheia's walking speed is 14.7 miles per hour.

Hatt and Chris will be 805 miles apart in approximately 6.145 hours. To find their walking speeds, we need to solve these equations based on the given information:

Distance = Speed × Time

For Elvira:

4.7 miles = x miles/hour × 0.5 hours

4.7 miles = 0.5x miles

Dividing both sides by 0.5:

9.4 = x

So Elvira's speed is 9.4 miles per hour.

For Aletheia:

4.7 miles = (x - 0.6) miles/hour × (1/3) hours

4.7 miles = (1/3)(x - 0.6) miles/hour

Multiplying both sides by 3:

14.1 = x - 0.6

Adding 0.6 to both sides:

14.7 = x

So Aletheia's speed is 14.7 miles per hour.

Therefore, Elvira's speed is 9.4 miles per hour, and Aletheia's speed is 14.7 miles per hour.

Hatt and Chris leave their uncle's house in Phoenix at the same time. Matt drives west on I-60 at a speed of 77 miles per hour, and Chris drives east on I-60 at a speed of 54 miles per hour. We need to find out how many hours it will take for them to be 805 miles apart.

To solve this, we can use the concept of relative speed. When two objects are moving in opposite directions, their relative speed is the sum of their individual speeds.

Relative Speed = Speed of Object 1 + Speed of Object 2

In this case, Hatt and Chris are driving in opposite directions, so their relative speed is:

Relative Speed = 77 miles per hour + 54 miles per hour
