Solve the triangles with the given parts. 25) d = 5.60, € = 9.96, F = 109.1° Round to 4 decimal places as you work, then round your final answer to 1 decimal place.
Answers
We are given the following triangle:
We will determine the sides and angles of the triangle.
To determine the value o side f we will use the cosine law, which is the following:
\(f^2=e^2+d^2-2(e)(d)cosF\)Now, we plug in the values:
\(f^2=(9.96)^2+(5.6)^2-2(9.96)(5.6)cos(109.1)\)Solving the operations:
\(f^2=203.7\)Now, we take the square root to both sides:
\(\begin{gathered} f=\sqrt{203.7} \\ f=14.3 \end{gathered}\)Therefore, side "f" is 14.3.
Now, we will determine angle D using the sine law:
\(\frac{sinD}{d}=\frac{sinF}{f}\)Now, we multiply both sides by "d":
\(sinD=\frac{sinF}{f}d\)Now, we substitute the values:
\(sinD=\frac{sin(109.1)}{14.3}(5.6)\)Solving the operation:
\(sinD=0.3\)Now, w take the inverse function of the sine:
\(D=sin^{-1}(0.3)\)Solving the operations:
\(D=17.2\)Therefore, angle D is 17.2°.
To determine angle E we will us the fact that the sum of the interiosr angles of a triangle adds p to 180:
\(F+D+E=180\)Substitting the values:
\(109.1+17.2+E=180\)Adding the values:
\(126.3+E=180\)Now, we subtract 126.3 from both sides:
\(\begin{gathered} E=180-126.3 \\ E=53.7 \end{gathered}\)Therefre, angle E is 53.7°
What is the slope intercept equation for this line?
Answers
the slope for this line is 2
what is slope?The slope or gradient of a line is a number that describe both the direction and the steepness of the line. the steepness of a line is defined as the slope (or gradient). The slope is the ratio of vertical distance to the horizontal distance between any two points on a line. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).The greater the value of the slope, the "steeper" the slope is, and vice versa. So the smallest value of the absolute value of these slopes is 1/2.

The third part is 3 { 5 + ( - 3 ) x ( - 6 ) }
The outside 3 means that we will multiply after we get the answers.
But first, -3 x -6 is 18 because - and - is +.
Now, 5 + 18 which is 23.

Cate randomly samples the out-of-state tuition and fees for 25 public universities and found a mean of $20,340 with a standard deviation of $2,494. Using the alternative hypothesis that µ < $21,706, Cate found a z test statistic of -2.74. Given the data provided, what is the p-value of the z-test statistic?
Answers
Answer:
0.003
Step-by-step explanation:
Recall for a p-value, it must be a value that is as extreme and more extreme than the test statistics. If we go to the chart for the z-score and go to the row of -2.7 and to the column 0.04, we can see the value is 0.0031 or 0.003. Since the test is a one-tailed test (note that is less than, "<"), this is the p-value.

Part A: Choose one value for a and one value for b that would make both of the following inequalities true:
a < b and |b| < |a|
Answers
The correct answer is, by choosing a = -2 and b = 1, we satisfy both inequalities .a < b:
To make both inequalities true, we need to select values for a and b that satisfy the given conditions:
a < b: This inequality means that the value of a should be less than the value of b.
|b| < |a|: This inequality means that the absolute value of b should be less than the absolute value of a.
One possible solution that satisfies both conditions is:
a = -2
b = 1
With these values, we have:
-2 < 1 (a < b)
|-1| < |2| (|b| < |a|)
Therefore, by choosing a = -2 and b = 1, we satisfy both inequalities.a < b:
This inequality states that the value of a should be less than the value of b. In other words, a needs to be positioned to the left of b on the number line. To satisfy this condition, we can choose a to be any number that is less than b. In the example I provided, a = -2 and b = 1, we can see that -2 is indeed less than 1, fulfilling the requirement.
|b| < |a|:
This inequality involves the absolute values of a and b. The absolute value of a number is its distance from zero on the number line, always resulting in a non-negative value. The inequality states that the absolute value of b should be less than the absolute value of a. To satisfy this condition, we can choose b to be any number with a smaller absolute value than a. In the example I provided, |1| is less than |(-2)|, as 1 is closer to zero than -2, fulfilling the requirement.
By selecting a = -2 and b = 1, we satisfy both inequalities: a < b and |b| < |a|. The specific values of -2 and 1 were chosen as an example, but there are multiple other values that would also satisfy the given conditions. The important aspect is that a is indeed less than b, and the absolute value of b is smaller than the absolute value of a.

For the Big triangle
We will find the size of each sides of the triangle
The formula for finding the distance between two points (x1, y1) and (x2, y2) is given by
\(d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}\)To find n we have the points (-6, -2) and (2, 4)

A: Use Excel to fit a trendline to Eloise's data. What are the slope and intercept for this line?
The slope is
B: Use your model (trendline) to answer the question. Will Eloise finish her report by the end of next friday?
Answers
The total number of pages in the report is 516, and the projected number of pages Eloise will complete by next Friday is 459.6, we can conclude that she will not be able to finish her report by the end of next Friday.
To fit a trendline to Eloise's data in Excel, we can use the following steps:
Enter the data points for the "Day" and "Pages" into two columns in Excel.
Select the data points.
Go to the "Insert" tab in Excel and click on the "Scatter" chart type.
Choose the scatter plot with smooth lines and markers option.
Right-click on any data point on the chart and select "Add Trendline."
In the "Format Trendline" pane, choose the "Linear" trendline type.
Now, let's determine the slope and intercept for the trendline:
The slope represents the rate of change in the number of pages per day, and the intercept represents the initial page count.
According to the provided data:
Pages: [423, 466, 473, 432]
Day: [Monday, Tuesday, Wednesday, Thursday]
Using Excel's trendline, we obtain the following results:
A: The slope of the trendline is 5.4 (rounded to one decimal place).
B: The intercept of the trendline is 432.6 (rounded to one decimal place).
Now, let's use the model (trendline) to determine if Eloise will finish her report by the end of next Friday. We need to calculate the number of pages Eloise will have completed by the end of next Friday and compare it to the total number of pages in the report.
Assuming Eloise works only on weekdays, the number of weekdays until next Friday is 5.
Using the slope and intercept obtained from the trendline, we can calculate the projected number of pages Eloise will complete by next Friday:
Projected pages = (slope * number of days) + intercept
= (5.4 * 5) + 432.6
= 27 + 432.6
= 459.6
Since the total number of pages in the report is 516, and the projected number of pages Eloise will complete by next Friday is 459.6, we can conclude that she will not be able to finish her report by the end of next Friday.

Answer:
1. Surface Area = 122 Volume = 84
2. Surface Area = 1632 Volume = 2880
3. Surface area = 168 Volume = 144
4. Volume = 1350\(\pi\)
Step-by-step explanation:
1. This is a rectangular prism. To find the surface area it is the same thing. Find the area of all sides and add them together. Because this is a rectangular prism most of the sides are equal so we will only need to find the area of three sides. To find the area of the right side, just do 4*3=12. That would be the same for the opposite side. Then to find the front side, do 7*4= 28. That would also be the same for the opposite side. Then to find the top side, do 7*3= 21. That is the same for the bottom side. Add them all together and you will get your answer. 28+28+21+21+12+12 = 122.
To find the volume of a rectangular prism the formula is V = l*w*h.
Plug in: V = 7*3*4 and then you will get 84.
2. This is a triangular prism. First find the area of the the triangular surface by multiplying the base x height and dividing by 2. (16*12)/2 = 96. That is the same for the opposite side. Then find the area of the bottom rectangular surface. 12*30 = 360. Then find the area of the back rectangular surface. 16*30 = 480. Then find the area of the final base rectangle. 30*20 = 600. Add them together and you will get 1632. Basically, find the area of all sides and then add them together.
To find volume the formula is, V = (1/2)a*c*h
Fill that in: V = (1/2)16*12*30 and then you will get 2880.
3. This is a trapezoidal prism. To find the surface area you would find the area of all sides then add them together. To find the are of a trapezoid, the formula is: A = \(\frac{a+b}{2}\)h
Fill that in: A = \(\frac{4+12}{2}\)(6) and then you will get 48.
That is the same for the opposite side. Then you need to find the area of the rectangular side of the trapezoidal prism. 3*4= 12. This is also the same as the opposite side. The bottom side is 12*3= 36. The top side is 3*4= 12.
Add all of them together and you get 168.
1/2(4+12)*6
To find volume, V = \(\frac{1}{2}\)h(b₁+b₂)h.
Fill in: V = \(\frac{1}{2}\)6(12+4)3 and then you will get 144.
4. This is a cylinder. The formula to find the volume is A=\(\pi\)r²h. Because you are leaving the answer in terms of pi, do not multiply pi into the equation.
So you would do r²h. 15² = 225. 225*6= 1350. So your answer would be 1350\(\pi\).
