Step-by-step explanation:
y=1/2x+1
y=mx+b where m=slope and b=y-intercept
in this case, m=1/2, b=1
y-intercept: (0, 1)
---------------------------------
y=-x+4
y=mx+b where m=slope and b=y-intercept
in this case, m=-1, b=4
y-intercept: (0, 4)
------------------------------------
1/2x+1=-x+4
1/2x-(-x)+1=4
1/2x+x=4-1
1/2x+2/2x=3
3/2x=3
x=3/(3/2)
x=(3/1)(2/3)
x=6/3
x=2
substitute x=2, into y=1/2x+1
y=1/2(2)+1=1+1=2
x=2, y=2.

nicole is flying two kites. she has 104 feet of string out to one kite and 110 feet out to the other kite. the angle formed by the two strings is 26 as shown in the figure below. find the distance between the kites.
Answer:
48.49 feet
Step-by-step explanation:
The diagrammatic sketch of the information provided in the question was attached in the image below.
From the image below, the distance between the two kites is denoted by (c) and can be determined by using the cosine angle rule which is expressed as:
[tex]c^2 = a^2 + b^2 -2ab cos \ C[/tex]
where;
a = 110
b = 104
Cos C = 26°
Then;
[tex]c^2 = 110^2 + 104^2 -2(110)(104) cos \ 26 \\ \\ c^2 = 12100 + 10816- 22880 ( 0.8988) \\ \\ c^2 = 22916- 20564.544 \\ \\ c^2 = 2351.456 \\ \\ c= \sqrt{2351.456} \\ \\ \mathbf{ c = 48.49 \ feet}[/tex]

Answer:
is the number 2?
Step-by-step explanation:
Answer:
The number could be
1 1/2 or -2
explanation:
From the data, taking the number to be x, we write:
2x^2 + x =6
Subtract 6 from both sides.
2x^2 + x - 6 = 0
Factorise.
2x^2 + 4x - 3x - 6 = 0
2x(x + 2) - 3(x + 2) = 0
(2x - 3)(x + 2) = 0
2x - 3 = 0 or x +2 = -2
x = 3/2 = 1 1/2 or x = -2
The circumference of Joe's bicycle wheel is 65 inches. What is the radius of the wheel? round to the nearest tenth
Answer:
10.3
Step-by-step explanation:
Answer:
10.4 in.
Step-by-step explanation:
To find the radius of a circle from the circumference, divide the circumference by pi, then, divide the quotient by 2.
65 is the circumference of Joe's bicycle.
65 ÷ 3.14 = 20.7006369427
20.7006369427 ÷ 2 = 10.3503184714
10.3503184714 ≈ 10.4
Therefore, 10.4 is the radius of the wheel rounded to the nearest tenth.

One urn contains one blue ball (labeled B1) and three red balls (labeled R1, R2, and R3). A second urn contains two red balls (R4 and R5) and two blue balls (B2 and B3). An experiment is performed in which one of the two urns is chosen at random and then two balls are randomly chosen from it, one after the other without replacement. a. Construct the possibility tree showing all possible outcomes of this experiment. b. What is the total number of outcomes of this experiment
Answer:
(a) See attachment for tree diagram
(b) 24 possible outcomes
Step-by-step explanation:
Given
[tex]Urn\ 1 = \{B_1, R_1, R_2, R_3\}[/tex]
[tex]Urn\ 2 = \{R_4, R_5, B_2, B_3\}[/tex]
Solving (a): A possibility tree
If urn 1 is selected, the following selection exists:
[tex]B_1 \to [R_1, R_2, R_3]; R_1 \to [B_1, R_2, R_3]; R_2 \to [B_1, R_1, R_3]; R_3 \to [B_1, R_1, R_2][/tex]
If urn 2 is selected, the following selection exists:
[tex]B_2 \to [B_3, R_4, R_5]; B_3 \to [B_2, R_4, R_5]; R_4 \to [B_2, B_3, R_5]; R_5 \to [B_2, B_3, R_4][/tex]
See attachment for possibility tree
Solving (b): The total number of outcome
For urn 1
There are 4 balls in urn 1
[tex]n = \{B_1,R_1,R_2,R_3\}[/tex]
Each of the balls has 3 subsets. i.e.
[tex]B_1 \to [R_1, R_2, R_3]; R_1 \to [B_1, R_2, R_3]; R_2 \to [B_1, R_1, R_3]; R_3 \to [B_1, R_1, R_2][/tex]
So, the selection is:
[tex]Urn\ 1 = 4 * 3[/tex]
[tex]Urn\ 1 = 12[/tex]
For urn 2
There are 4 balls in urn 2
[tex]n = \{B_2,B_3,R_4,R_5\}[/tex]
Each of the balls has 3 subsets. i.e.
[tex]B_2 \to [B_3, R_4, R_5]; B_3 \to [B_2, R_4, R_5]; R_4 \to [B_2, B_3, R_5]; R_5 \to [B_2, B_3, R_4][/tex]
So, the selection is:
[tex]Urn\ 2 = 4 * 3[/tex]
[tex]Urn\ 2 = 12[/tex]
Total number of outcomes is:
[tex]Total = Urn\ 1 + Urn\ 2[/tex]
[tex]Total = 12 + 12[/tex]
[tex]Total = 24[/tex]

Problem 7
Answer: 60-----------------------
Explanation:
Let's say we only worried about the colors and the sizes. We have 3 colors and 4 sizes, giving 3*4 = 12 different combos. Think of a table that's 3 rows and 4 columns. We'd have 12 inner cells. Each cell represents a different combo.
This idea extends out to not just two factors, but we can have as many as we want. In short, we simply multiply the values given to us: 3*4*5 = 12*5 = 60 different t-shirts. Your math textbook or your teacher may refer to this method as the counting principle, though they may use another term.
========================================================
Problem 8
Answer: 224-----------------------
Explanation:
We use the same idea as problem 7.
4*7*8 = 28*8 = 224 different coats
As an alternative, you can draw out a tree diagram. However, these types of drawings can get very cluttered.
========================================================
Problem 9
Answer: 5040-----------------------
Explanation:
We'll use the same idea as before.
We have 10 choices for the first slot (0 through 9)
Once the first digit is selected, then we have 10-1 = 9 choices left for slot two
Then slot three has 9-1 = 8 choices, and so on.
We have this countdown: 10, 9, 8, 7
The countdown stops once we filled out the four slots. Multiply these values to get the final answer: 10*9*8*7 = 5040. The multiplication step is where we refer to the ideas mentioned in problems 7 and 8 earlier.
Keep in mind that this allows for 0 to be in the first slot. So a number like "0179" is one possibility here. If 0 is not allowed for the first digit, then you'll compute the answer like so:
9*9*8*7 = 4536
This is because we have 9 choices for the first digit, then 9 for the next, and so on. I would ask your teacher for clarification on this one.
Each year the admissions committee at a top business school receives a large number of applications for admission to the MBA program and they have to decide on the number of offers to make. Since some of the admitted students may decide to pursue other opportunities, the committee typically admits more students than the ideal class size of 720 students. You were asked to help the admission committee estimate the appropriate number of people who should be offered admission. It is estimated that in the coming year the number of people who will not accept the admission is normally distributed with mean 50 and standard deviation 21. Suppose for now that the school does not maintain a waiting list, that is, all students arc accepted or rejected. a. Suppose 750 students are admitted. What is the probability that the class size will be at least 720 students'
Answer:
0.1711 = 17.11% probability that the class size will be at least 720 students
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
Our random variable X is the number of students not taking admission, which has mean [tex]\mu = 50[/tex] and standard deviation [tex]\sigma = 21[/tex]
a. Suppose 750 students are admitted. What is the probability that the class size will be at least 720 students?
30 or less students do not take admission, which means that this is the pvalue of Z when X = 30.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30 - 50}{21}[/tex]
[tex]Z = -0.95[/tex]
[tex]Z = -0.95[/tex] has a pvalue of -0.1711
0.1711 = 17.11% probability that the class size will be at least 720 students

Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
