What is triangle?"It is a polygon having three sides, three vertices.""The sum of all angles of triangle is 180°"
For given example,
As we know for ΔNOP,
[tex]\frac{n}{sinN}=\frac{0}{sinO}=\frac{p}{sinP}[/tex]
We know that the sum of all angle of triangle is 180°
For ΔNOP,
⇒ ∠N +∠O + P = 180°
⇒ 16° + ∠O + 163° = 180°
⇒ ∠O = 180 - 179
⇒ ∠O = 1°
The length of n is,
[tex]\frac{n}{sinN}=\frac{0}{sin1}\\\\n(sin1)=0(sin16)\\\\0.01745(n)=720(0.27564)\\\\n=\frac{198.4608}{0.01745}\\\\n=11373.112\\\\n\approx 11373.1~in.[/tex]
Therefore, the length of n is 11373. 3 inches

Harry's math test scores are listed below.
95, 90, 85, 40, 100, 100, 95, 100, 85, 90
Which measure of central tendency most closely describes Harry's overall
performance on the math tests?
Answer:
Mode
Step-by-step explanation:
The mode is the measure of the central tendency in which the number is appeared many times
As in the given situation
The 100 would be appear 3 times
So this represent the mode
Hence, the mode that measures the central tendency is most close and describe the math test performance

Sean is paid biweekly. His annual salary is $42,500. What is his biweekly salary to the nearest cent?
Answer: $1,634.62
Step-by-step explanation:
There are 52 weeks in a year. However, Sean does not get paid every week, he gets paid every other week. 52/2 = 26, thus he gets paid 26 times a year.
His annual salary is 42,500. To figure out his salary in each paycheck, divide the net salary by the number of pay periods per year. In this case 42,500/26.
42500/26 = 1,634.62 (rounded to the nearest cent)

the boss gives all his employees a 6% raise, paul used to earn $11 an hour now he earns
Answer:
Now he earns $11.66 per hour.
Step-by-step explanation:
6% raise
This means that now the employees will earn 100% + 6% = 106% = 1.06 of the previous amount they earned, that is, their previous earnings will be multiplied by 1.06.
Paul used to earn $11 an hour now he earns
Multiplying by 1.06
11*1.06 = 11.66
Now he earns $11.66 per hour.

What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
The point of their joint is called vertex of that angle.
If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.
A line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed.
We can conclude that Line segment QR is part of Line QS. Point Q is the vertex of angle

(f + g)(3) = 9
Step-by-step explanation:
Given:
f(x) = x² + 1
g(x) = x - 4
Required:
(f + g)(3)
SOLUTION:
✔️Find f(3) by substituting x = 3 into f(x) = x² + 1:
f(3) = (3)² + 1 = 9 + 1
f(3) = 10
✔️Find g(3) by substituting x = 3 into g(x) = x - 4:
g(3) = 3 - 4
g(3) = -1
✔️Find (f + g)(3):
(f + g)(3) = f(3) + g(3)
= 10 + (-1)
= 10 - 1
(f + g)(3) = 9

Answer:
[tex]f(x) = 9x[/tex]
Step-by-step explanation:
Given
The attached table
Required
Rule of the table
First, we calculate the slope(m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (3,27)[/tex]
[tex]m = \frac{27 -0}{3 - 0}[/tex]
[tex]m = \frac{27}{3}[/tex]
[tex]m = 9[/tex]
The table equation is:
[tex]y - y_1 = m(x - x_1)[/tex]
So, we have:
[tex]y - 0 = 9(x - 0)[/tex]
[tex]y - 0 = 9(x)[/tex]
[tex]y= 9x[/tex]
Hence:
[tex]f(x) = 9x[/tex]
Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of and a standard deviation of or a score of 432 on a test with a mean of and a standard deviation of (Assume that the distributions being compared have approximately the same shape.)
Answer:
A score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has the highest relative position.
Step-by-step explanation:
Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 or a score of 432 on a test with a mean of 396 and a standard deviation of 40.
In order to find the solution, we need to calculate the z score value for each test.
The z score formula: [tex]z = \dfrac{\bar{x} -\mu}{s}[/tex] where [tex]\bar{x}[/tex] is the score, μ is the mean and s is the standard deviation.
Now for test 1:
Put [tex]\bar{x}=38, \mu=30 \text{ and } s=10[/tex] in the above formula.
[tex]z = \dfrac{38 -30}{10}[/tex]
[tex]z = 0.8[/tex]
For test 2:
Put [tex]\bar{x}=4.2, \mu=2.5 \text{ and } s=1.2[/tex] in the above formula.
[tex]z = \dfrac{4.2 -2.5}{1.2}[/tex]
[tex]z \approx 1.417[/tex]
For test 3:
Put [tex]\bar{x}=432, \mu=396 \text{ and } s=40[/tex] in the above formula.
[tex]z = \dfrac{432 -396}{40}[/tex]
[tex]z =0.9[/tex]
Since the z score value of test 2 is greater so a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has a highest relative position.

(+ 3 and 3x + y > 2
-2
Answer:
first choice: y≥1/3 x+3 and 3x-y>2
Step-by-step explanation:
The system of linear inequalities is: [tex]y \ge \frac{1}{3}x + 3[/tex] and [tex]3x -y > 2[/tex]
The orange lineThe equation of the orange line is calculated using:
[tex]y = \frac{y_2 - y_1}{x_2-x_1} \times (x -x_1) + y_1[/tex]
This gives
[tex]y = \frac{3- 4}{0-3} \times (x -3) + 4[/tex]
[tex]y = \frac{- 1}{-3} \times (x -3) + 4[/tex]
[tex]y = \frac{1}{3} \times (x -3) + 4[/tex]
Open the bracket
[tex]y = \frac{1}{3}x -1 + 4[/tex]
[tex]y = \frac{1}{3}x + 3[/tex]
The inequality has a thick line, and the upper region is shaded.
So, the inequality is:
[tex]y \ge \frac{1}{3}x + 3[/tex]
The gray lineThe equation of the gray line is calculated using:
[tex]y = \frac{y_2 - y_1}{x_2-x_1} \times (x -x_1) + y_1[/tex]
This gives
[tex]y = \frac{4- 1}{2-1} \times (x -1) + 1[/tex]
[tex]y = \frac{3}{1} \times (x -1) + 1[/tex]
[tex]y = 3 \times (x -1) + 1[/tex]
Open the bracket
[tex]y = 3x -3 + 1[/tex]
[tex]y = 3x -2[/tex]
The inequality has a dotted line, and the right region is shaded.
So, the inequality is:
[tex]y < 3x -2[/tex]
Rewrite as:
[tex]3x -2 > y[/tex]
So, we have:
[tex]3x -y > 2[/tex]
Hence, the system of linear inequalities is:
[tex]y \ge \frac{1}{3}x + 3[/tex] and [tex]3x -y > 2[/tex]

When a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. Write
an equation and solve it to find the value of n.
Answer:
n=29
Step-by-step explanation:
Not sure how to write an equation for it.
But, I did 88 divided by 4 which is 22 then plus 7 29
88/4+7=n that is the best I can think of.
If a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. The equation is 4(n-7)=88 and value of n is 24.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
a number n is decreased by 7 and then the result is multiplied by 4
Decreased means subtracted, the number seven is subtracted from n, which gives us n-2.
Then n-2 is multiplied by 4
4(n-2)
the product is equal to 88.
4(n-2)=88
Now we need to solve for n.
Apply distributive property on left hand side
4n-8=88
Add 8 on both sides
4n=96
Divide both sides by 4
n=24
Hence the value of number n is 24 and the Equation for sentence is 4(n-7)=88.
