To find the angles of the triangle with vertices P(3, 0), Q(0, 3), and R(5, 5), we can use the distance formula to determine the lengths of the sides and then apply the Law of Cosines to find the angles. The given information states that angle LRPQ is equal to 67 degrees.

To determine the other two angles, we can calculate the lengths of the sides PQ, QR, and RP using the distance formula. The length of PQ is √((0 - 3)² + (3 - 0)²) = √18. The length of QR is √((5 - 0)² + (5 - 3)²) = √29, and the length of RP is √((5 - 3)² + (5 - 0)²) = √13.

Next, we can use the Law of Cosines to find the angles. Let's denote angle P as α, angle Q as β, and angle R as γ. We have the following equations:

cos(α) = (18 + 13 - 29) / (2 * √18 * √13) ≈ 0.994 (rounded to three decimal places)

cos(β) = (18 + 29 - 13) / (2 * √18 * √29) ≈ 0.287 (rounded to three decimal places)

cos(γ) = (13 + 29 - 18) / (2 * √13 * √29) ≈ 0.694 (rounded to three decimal places)

To find the angles, we can take the inverse cosine of these values. Using a calculator, we get α ≈ 7 degrees, β ≈ 71 degrees, and γ ≈ 37 degrees (rounded to the nearest degree).

Therefore, the three angles of the triangle are approximately 7 degrees, 71 degrees, and 37 degrees.

Answer:

the correct answer is 84.5$

Step-by-step explanation:

The way how i got this because 3*9 for the t shirts

2*20 for the jeans

and 5*3.50 for the socks

Answer:

$84.50

Step-by-step explanation:

So we know she buys 3 nine dollar shirts

$9.00 times 3 shirts is $27.00

She also buys two pairs of jeans

$20.00 times 2 is $40.00

Finally she buys 5 pairs of socks

$3.50 times 5 is 17.50

so lets add it all up

27.00

40.00

17.50

Answer:

18x + 28 is the perimeter

Step-by-step explanation:

As perimeter is the som of all side

So    P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4

          = 6x+3x+6x+2x+x + 8+6+5+2+3+4

         = 18x + 28

Answer:

46

Step-by-step explanation:

15% of 40 is 6 so you add 6 to 40

Answer:46

Step-by-step explanation:

15% of 40=?

multiply 15 by 40 and divide by 100

15 * 40 / 100 = 6

add 6 to 40

40+6=46

Therefore, the number of cats that they expect is 46.

Answer:

If you're timed then I would say,

Yes this is a random study because the problem specifically states that the survey samples were randomly selected from populations.

I think that is the answer! However, if you have time I would wait for another person to answer as well because I'm terrible at statistics :(

Answer:

No, its nat a random sample

Step-by-step explanation:

Its not a random sample because you have already selected two populations (the two largest US cities) which may or may not be representative of the vast majority of the country.

There are two methods that can be used to distort a bar graph. These are: A. stretching the vertical scale and B. starting the vertical axis at a point other than the origin. Therefore, the correct options are (A) and (B).

Distorting a bar graph means changing the way it looks so that it presents data in a way that is misleading or confusing to the viewer. To achieve this, the person creating the graph may use certain methods, including stretching the vertical scale, starting the vertical axis at a point other than the origin, and making the width of the bars proportional to their height.

Stretching the vertical scale refers to the act of increasing the distance between the values on the vertical axis. By doing this, the differences between the data values will appear larger than they actually are, and this can lead the viewer to draw incorrect conclusions.

On the other hand, starting the vertical axis at a point other than the origin means that the graph will not start at zero. This makes the differences between the data values appear more significant than they actually are, which can also mislead the viewer. In contrast, making the width of the bars proportional to their height is not a method of distorting a bar graph. Instead, this method is used to create a more accurate and representative graph, especially when the data points are close to each other. Therefore, the correct options are (A) and (B).

Answer:

B, D, E

Step-by-step explanation:

If a line is parallel to another line, then the slope has to be the same. Thus we first want to find the slope of the line given, by using the slope formula: m = (y_1 - y_0)/(x_1 - x_0): (2 - 4)/(-2-3) = 2/5

We proceed to find the slope of the following answer choices:

A. (-3-(-5))/(-7-(-2)) = -2/5

B. (-1-1)/(-6-(-1)) = 2/5

C. (5 - 0)/(2-0) = 5/2

D. (2-0)/(6-1) = 2/5

E. (2-0)/(8-3) = 2/5

Thus, we have B, D, E

The most accurate statement regarding the risk tolerance parameter is:

The risk tolerance parameter influences the relationship between a payoff and the utility of the payoff.

The risk tolerance parameter is a measure of an individual's or firm's willingness to accept risk in exchange for potential reward. It influences the utility function, which maps payoffs to the utility they provide.

A higher risk tolerance parameter implies a greater willingness to accept risk, and a lower risk tolerance parameter implies a lesser willingness to accept risk. The parameter can be any positive number, not just between 0 and 1. Statements 1, 2, and 3 are incorrect.

Answer:

no real answer

Step-by-step explanation:

distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r

then we have 7-3r=-8-3r

from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.

since 7 doesn't equal -8, there is no answer.

if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers

Answer:

Look below

Step-by-step explanation:

(i) Sharon is not correct because in the first bag, the proportion is of red counters to yellow counters.

In the second bag, the proportion is of red counters to all the counters in the bag. Therefore the proportions are not the same.

(ii) Let x be the total amount of counters (in each bag)...

Then the amount of red counters would be

\(\frac{1}{5} x\)

And the amount of yellow counters would be

\(\frac{4}{5} x\)

For the second bag, the amount of red counters would be

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

And the amount of yellow counters would be

\(\frac{3}{4} x\)

The correct answer to the given question about chi-square distribution and sampling distribution is a. 5 or higher.

The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic only if the sample size is large. Generally, a sample size of 5 or higher is considered large enough for this approximation. This is because the chi-square distribution approaches a normal distribution as the degrees of freedom increase, and a sample size of 5 or more provides enough degrees of freedom for the approximation to be valid. However, if any expected count is less than 5, then the approximation may not be reliable, and alternative methods should be considered (such as Fisher's exact test or the Monte Carlo method).
