Answers
Answer:83.3∘
Step-by-step explanation:
The measure of angle O from the triangle MNO is 156.92°.
What is cosine rule?In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.
The formula for the cosine rule is c=√(a²+b²-2ab cosC)
here, we have,
Given that,
in triangle MNO,
m = 720 cm, n = 160 cm and o=870 cm.
Now, 870=√(720²+160²-2×720×160 cosO)
870²=720²+160²-2×720×160 cosO
756900=544000-230400 cosO
212900=-230400 cosO
cosO= -212900/230400
cosO= -0.92
∠O=156.92°
Therefore, the measure of angle O from the triangle MNO is 156.92°.

Answers
Answer:
C) 48.3
Step-by-step explanation:
The lines are parallel, meaning that when the third line is intersecting them both, the angles formed will be exactly the same. The top angle that is to the right is 25°, meaning that he bottom angle to the left is 25°. All that is left is to find the last two angles in order to find out what the answer to the equation is. The 25° angle is next to a triangle causing the lines to be flat, or 180°.
180 - 25 = 155
That means the bottom angle to the right is 155. In order to find x, subtract 10 and divide by 3.
3x + 10 - 10 = 155 - 10
3x = 135
3x/3 = 135/3
x = 48.3
PLZ HELP !!!!!!!Solve for the value of x and y
68
(4x - 2)
30
Answers
Answer: 10
Step-by-step explanation:
Simplifying
68 = 4x + -2 + 30
Reorder the terms:
68 = -2 + 30 + 4x
Combine like terms: -2 + 30 = 28
68 = 28 + 4x
Solving
68 = 28 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
68 + -4x = 28 + 4x + -4x
Combine like terms: 4x + -4x = 0
68 + -4x = 28 + 0
68 + -4x = 28
Add '-68' to each side of the equation.
68 + -68 + -4x = 28 + -68
Combine like terms: 68 + -68 = 0
0 + -4x = 28 + -68
-4x = 28 + -68
Combine like terms: 28 + -68 = -40
-4x = -40
Divide each side by '-4'.
x = 10
Simplifying
x = 10
Answer:
x = 10, y = 112
Step-by-step explanation:
4x - 2 + 30 and 68 are vertical angles and are congruent , then
4x - 2 + 30 = 68
4x + 28 = 68 ( subtract 28 from both sides )
4x = 40 ( divide both sides by 4 )
x = 10
------------------------
y and 68 lie on a straight line and sum to 180° , then
y + 68 = 180 ( subtract 68 from both sides )
y = 112
3. A researcher randomly selects a sample of 61 former student leaders from a list of graduates of UNCG who had participated in leadership positions while a student. She discovered that it has taken an average of 4.97 years for these student leader graduates to finish their degrees, with a standard deviation of 1.23. The average for the entire student body is 4.56 years. Is the difference between student leaders and the entire student population statistically significant at the alpha
Answers
Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
Determine if the difference between the student leaders and the entire student population is statistically significant at alpha
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05

17. The puppy will grow 16 inches
One foot equals 12 inches. Lena's puppy will grow to be at most 28 inches. 28-12=16 inches.
18. 24.5
the possible values of the combined weights of the kittens is not more than 24.5 ounces. Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces

Answers
The difference of the two complex numbers (5 + 3i) and (2 + 9i) is; 3 - 6i.
What is the difference of the two complex numbers (5 + 3i) and (2 + 9i)?It follows from the task content that the two difference of the two complex numbers (5 + 3i) and (2 + 9i) be determined.
Since the numbers given are; (5 + 3i) and (2 + 9i).
The difference can be mathematically as follows;
( 5 + 3i ) - ( 2 + 9i )
By the Distributive property; we have;
5 + 3i - 2 - 9i
Collect like terms so that we have;
= 5 - 2 + 3i - 9i
= 3 - 6i
On this note, the difference between the two complex numbers is; 3 - 6i.
