Answer:

x = 16°

4x-7 = 57°

3x+4 = 52°

5x-9 = 71°

Step-by-step explanation:

All angles of any triangle add up to 180°, so if we add up each equation and set it equal to 180 we can find x.

4x-7 + 3x+4 + 5x-9 = 180

Simplify by combining like terms.

12x-12 = 180

Then, do inverse operations to find x.

12x=192

x=16

Now that we found x, we can substitute 16 for x in each angle equation in the triangle.

4(16)-7 = 57

3(16)+4 = 52

5(16)-9 = 71

The odds in favor of the event happening are 5 to 4.

We have,

To find the odds in favor of an event happening, we use the formula:

Odds in favor = Probability of the event happening / Probability of the event not happening

In this case,

The probability of the event happening is 5/9.

The probability of the event not happening is 1 - 5/9, which simplifies to 4/9. So the odds in favor of the event happening are:

Odds in favor

= 5/9 / 4/9

= 5/4

Therefore,

The odds in favor of the event happening are 5 to 4.

Step-by-step explanation:

The percentage of the students at the university which are foreign are 25% by conditional probability formula.

According to the question,  10% of all college students are foreign students who also smoke and it is also known that 40% of all foreign college students smoke.

We use the conditional probability formula to solve this question.

Let foreign students be denoted as F

Let students smoking be denoted as S

We know that 10% of all college students are foreign students who also smoke this means

P(F ∩ S) = 0.1

and 40% of all foreign college students smoke which means

P(S/F) = 0.4

So, the percentage of the students at this university who are foreign can be calculated as  

\(P(F) = \frac{0.1}{0.4}\) = 0.25

Using more than 30% amount of your available credit limit can have a negative impact on your credit score, so if you have a credit limit of $5,000 and only $100 left, you should be careful with your spending.

1. Determine total credit limit: $5,000

2. Determine remaining credit before limit is reached: $100

3. Calculate the percentage of the credit limit that has been used: $100/$5,000 = 0.02 = 2%

4. Determine if the percentage of credit limit used is more than 30%: 2% < 30%

5. Conclusion: Your credit score will be affected if you max out your credit limit.

Your credit score will be affected if you max out your credit limit, meaning if you reach or exceed your credit limit. To calculate this, you will need to determine the total credit limit, the remaining credit before the limit is reached, and then calculate the percentage of the credit limit that has been used. If the percentage of credit limit used is more than 30%, then your credit score will be negatively impacted.

the area of the surface that corresponds to the part of the plane 13x + 5y + z = 65 lying in the first octant is 32.5 square units.

To find the area of the surface that corresponds to the part of the plane 13x + 5y + z = 65 lying in the first octant, we need to find the equation of the portion of the plane that lies in the first octant and then calculate the surface area of that portion.

First, we need to find the intercepts of the plane with the x, y, and z-axes. Setting x = 0, we get:

5y + z = 65

Setting y = 0, we get:

13x + z = 65

Setting z = 0, we get:

13x + 5y = 65

Solving these three equations simultaneously, we get:

x = 5, y = 13, z = 0

So the plane intersects the x-axis at (5,0,0), the y-axis at (0,13,0), and the z-axis at (0,0,65).

The part of the plane that lies in the first octant is bounded by the x-axis, the y-axis, and the line connecting (5,0,0) and (0,13,0). This triangular region has a base of length 5 and a height of 13, so its area is (1/2)513 = 32.5.

The researchers are investigating the perception of three-dimensional shapes on computer screens and specifically examining the components of a square figure or cube necessary for viewers to perceive details of the shape. They vary the stimuli to include fully rendered cubes, cubes with incomplete sides, and cubes with missing corner information. Four participants are recruited for an intense study, and their accuracy rates are measured across the three figure conditions. The trials are presented in different orders for each participant using a random-numbers table to determine unique sequences.

In this study, the researchers are interested in understanding how viewers perceive details of three-dimensional shapes on computer screens. They manipulate the stimuli by presenting fully rendered cubes, cubes with incomplete sides, and cubes with missing corner information. By varying these components, the researchers aim to identify which elements are necessary for viewers to accurately perceive the shape.

Four participants are recruited for an intense study, indicating a small sample size. While a larger sample size would generally be preferred for generalizability, intense studies often involve fewer participants due to the time and resource constraints associated with conducting a large number of trials. This approach allows for in-depth analysis of individual participant performance.

The participants are trained on how to detect subtle deformations in the shapes, which suggests that the study aims to assess their ability to perceive and discriminate fine details. After the training, the participants' accuracy rates are measured across the three different figure conditions, likely reported as a percentage of correctly identified shape details.

To minimize potential biases, the trials are presented in different orders for each participant, using a random-numbers table to determine unique sequences. This randomization helps control for order effects, where the order of presenting stimuli can influence participants' responses.

To evaluate the given integral by reversing the order of integration, we first need to write it in terms of the new order. This can be done by considering the limits of integration for each variable. The original integral is:∫[0 to 3]∫[0 to 9] 5e^(2x) dx dyTo reverse the order of integration, we need to first consider the limits of integration for y. The limits for y are from 0 to 3, which means that the integral with respect to y will have these limits.

To evaluate the integral by reversing the order of integration. The given integral is:

∫(from 0 to 3) ∫(from 5 to 9) 5e^(x^2) dx dy.

To reverse the order of integration, we first need to find the new limits of integration. Currently, the region is defined by:

0 ≤ y ≤ 3
5 ≤ x ≤ 9

We will switch the order of integration to dy dx. To do this, we express y in terms of x:

x = 5
x = 9

So the new region is defined by:

5 ≤ x ≤ 9
0 ≤ y ≤ 3

Now, we rewrite the integral with the new order of integration:

∫(from 5 to 9) ∫(from 0 to 3) 5e^(x^2) dy dx.

Now, let's evaluate the integral step by step:

Step 1: Evaluate the inner integral with respect to y.

∫(0 to 3) 5e^(x^2) dy = 5e^(x^2) * y | evaluated from y=0 to y=3
= 15e^(x^2)

Step 2: Evaluate the outer integral with respect to x.

∫(5 to 9) 15e^(x^2) dx

Unfortunately, this integral does not have a closed-form . To obtain a numerical result, you would need to use numerical integration methods, such as Simpson's rule or the trapezoidal rule.

Answer: $521

Step-by-step explanation:

y = (-1/2)x - 7/2 is the equation of the given point and slope.

To graph the point (3, -5) and a line with a slope of -1/2, we can use the point-slope form of a linear equation.

The point-slope form of a linear equation is given by:

y - y1 = m(x - x1)

where (x1, y1) represents a point on the line, and m represents the slope.

Plugging in the values, we have:

y - (-5) = (-1/2)(x - 3)

Simplifying:

y + 5 = (-1/2)x + 3/2

Subtracting 5 from both sides:

y = (-1/2)x + 3/2 - 5

y = (-1/2)x - 7/2

Now we have the equation y = (-1/2)x - 7/2, which represents a line with a slope of -1/2 passing through the point (3, -5).

To graph the line, plot the point (3, -5) on the coordinate plane and then use the slope to find additional points. For every 2 units you move to the right, move 1 unit down to find other points. Connect the plotted points to draw the line.

The resulting graph will show the point (3, -5) and a line with a slope of -1/2.
