Answer:
1 = 61°
2 = 119°
3 = 61°
4 = 119°
5 = 119°
6 = 61°
7 = 119°
Step-by-step explanation:
∠1 and 61° are corresponding angles, therefore, they would be the same angle; ∠1 = 61°.
∠2 and 61° are supplementary angles, therefore, ∠2 would be 119°.
∠3 and ∠1 are vertical angles, therefore, ∠3 = 61°.
∠4 and ∠3 are supplementary angles, therefore, ∠4 would be 119°.
∠5 and 61° are supplementary angles, therefore, ∠5 would be 119°.
∠6 and ∠1 are alternate exterior angles, therefore, ∠6 would be 61°.
∠7 and ∠6 are supplementary angles, therefore, ∠7 would be 119°.
The top rail of a boat is 4 ft out of the water. If the water rises 3 ft, how far out of
the water is the top rail of the boat?
Answer:
Position of top rail of boat after increasing water level = 1 feet out of water
Step-by-step explanation:
Given:
Position of top rail of boat = 4 feet out of the water
Water level increases = 3 feet
Find:
Position of top rail of boat after increasing water level
Computation:
Position of top rail of boat after increasing water level = Position of top rail of boat - Water level increases
Position of top rail of boat after increasing water level = 4 - 3
Position of top rail of boat after increasing water level = 1 feet out of water

Question 9 (1 point)
Solve for X
K
50°
110°
P
R
w
30x
Answer:
x = 3
Step-by-step explanation:
Recall: Opposite angles in an inscribed quadrilateral are supplementary.
Thus,
m<R = 180 - m<P
m<R = 180 - 110
m<R = 70°
Recall: measure of inscribed angle = half of the intercepted arc
Thus:
m<R = ½(arc KPQ)
70 = ½(50 + 30x)
Multiply both sides by 2
2*70 = 50 + 30x
140 = 50 + 30x
140 - 50 = 50 + 30x - 50
90 = 30x
90/30 = 30x/30

Answer:
The median of this data range would be 54.5.
Step-by-step explanation:
In statistics and probability theory, the median is the data value dividing the larger half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value. To find the median, place the numbers in value order and find the middle number. In this case, from smallest to greatest, the data list would be 36, 43, 50, 50, 51, 58, 59, 60, 69, 73. If there are an even number of individual data points, you need to find the two values that are located in the middle of the data plot, add them together, and divide their sum by two to get the median. Because there are 10 individual data values, that means you need to use the 5th and 6th values to find the median, which is 51 and 58. [tex]\frac{51+58}{2}[/tex] = [tex]\frac{109}{2}[/tex] = 54.5, so that would be the median of this data set.

What is the surface area of the net? *inches squared*
9514 1404 393
Answer:
75 in^2
Step-by-step explanation:
The central vertical rectangle (including "ears") has dimensions
3 in wide by (9+2+2) = 13 in tall
Its area is
A = LW = (3 in)(13 in) = 39 in^2
__
The two rectangles either side of that have dimensions 2 in by 9 in. The area of each of them is
A = LW = (2 in)(9 in) = 18 in^2
__
The total net area is the sum of the areas of the parts:
left rectangle + central rectangle + right rectangle
= 18 in^2 + 39 in^2 + 18 in^2 = 75 in^2 . . . . surface area of the net

Choice 3: Kyra makes $700.00 a week in her job. She did such a great job this week that she is going to get a 15% raise next week. How much will her raise be?
Please help and this is a Percentage problem :)
Answer:
15/100 x 700 = 105
Step-by-step explanation:
Consider 15% as 15 because you always consider a percent out of 100, you can remember by the word 'cent' meaning 100.
You need to FIRST find out what the percentage is OF whenever coming across these types of problems.
And the keyword 'of' means to multiply.
Paul is spreading grass seed on an area of his lawn that is 10 feet wide and 12 feet long.

A. 4 bags
B. 8 bags
C. 80 bags
D. 400 bags

The area of the lawn is 120 square feet, and 15 x 8 =124.
A job fair was held at the Student Union. 25% of the students who attended received job offers. Of all of the students at the job fair, 40% were from the College of Business. Among these business students, 50% received job offers. Let J be the event that a student is offered a job. Let B be the event that the student is from the College of Business.
Requried:
a. Are events J and B independent? Why or why not?
b. Are events J and B mutually exclusive? Why or why not?
c. Joe, who is not a business student, attended the job fair. What is the probability that he received a job offer?
d. Another student, Samantha, received a job offer. What is the probability that she is a Business student?
Answer:
A) Both events are not independent.
B) Both events are not mutually exclusive
C) 8.33%
D) 80%
Step-by-step explanation:
A) Both events are not independent. This is because, If B occurs it means that it is very likely that J will occur as well.
B) Both events are not mutually exclusive. This is because it is possible for both events J and B to occur at the same time.
C) we want to find the probability that Joe who is not a business student will receive the job offer.
This is;
P(J|Not B) = P(J & Not B)/P(Not B)
Now,
P(J & Not B) = P(J) – (P(B) × P(J | B))
25% of the students who attended received job offers. Thus; P(J) = 0.25
40% were from the College of Business. Thus;
P(B) = 0.4
Among the business students, 50% received job offers. Thus;
P(J|B) = 0.5
Thus;
P(J & Not B) = 0.25 - (0.4 × 0.5)
P(J & Not B) = 0.25 - 0.2
P(J & Not B) = 0.05
Since P(B) = 0.4
Then, P(Not B) = 1 - 0.4 = 0.6
Thus;
P(J|Not B) = 0.05/0.6
P(J|Not B) = 0.0833 = 8.33%
D) This probability is represented by;
P(B | J) = P(B & J)/P(J)
P(B & J) = (P(B) × P(J | B)) = (0.4 × 0.5) = 0.2
P(B | J) = 0.2/0.25
P(B | J) = 0.8 = 80%
