Given the figure below find the values of x and z
(12x +2)°
94°
z°
Answers
Answer:
z = 94
x = 7
Step-by-step explanation:
The angle with a measure of 94° and the angle labeled "z" are vertical angles
Vertical angles are congruent ( equal to each other )
Which means that because "z"s vertical angle = 94° z also equals 94°
The angle labeled with the expression ( 12x + 2 ) and the angle with a measure of 94° are supplementary angles
Supplementary angles add up to equal 180
Hence, 94 + 12x + 2 = 180
^ (Note that this is the equation we will use to solve for x )
Now we solve for x
94 + 12x + 2 = 180
step 1 combine like terms
94 + 2 = 96
we now have 180 = 96 + 12x
step 2 subtract 96 from each side
180 - 96 = 84
96 - 96 cancels out
we now have 84 = 12x
step 3 divide each side by 12
84 / 12 = 7
12x / 12 = x
we're left with x = 12
Answer:
z = 94
x = 7

Ben measures the length of the street he lives on to be 80 000 cm. What is the street length in kilometres?
(1km 100 000 cm)
Answers
Answer:
.8Km
Step-by-step explanation:
There is exactly 100,000 CM in every KM, if someone such as Ben was to measure out 80,000, to convert to KM you'd take the given value and divide by the appropriate values.
80,000cm / 100,000cm = .8 KM
Street length in kilometers = 80,000 cm / 100,000 cm = 0.8 km
Therefore, the street length is 0.8 kilometers.

One day a store sold 28 sweatshirts. White ones cost $9.95 and yellow ones cost $13.50. In all, $321.20 worth of sweatshirts were sold. How many of each color were sold?
Answers
Answer:
white sold = 16
yellow sold = 12
Step-by-step explanation:
w = # of white sold
y = # of yellow sold
w + y = 28 solve this for w
w = 28 - y
9.95w + 13.5y = 321.20 substitute w = 28-y into this expression and solve for y
9.95(28-y) + 13.5y = 321.20
278.60 - 9.95y + 13.50y = 321.20
278.60 + 3.55y = 321.20
3.55y = 321.20 - 278.60 = 42.60
y = 42.60/3.55 = 12 substitute this into w = 28 - y and solve for w
w = 28 - 12 = 16

Write and solve an inequality to represent the scenario, then explain the solution.
Brianna has a $50 online gift certificate from a book store. The cost of each book is $9. There is also a shipping charge of $5 for her entire order. How many
books can Brianna buy without spending more than her gift certificate amount?
Enter the correct answers in the boxes.
Answers
Brianna can buy up to 5 books without spending more than her gift certificate amount.
We can set up the inequality: 9x + 5 <= 50. where x is the number of books Brianna can buy. To solve for x, we can start by subtracting 5 from both sides of the inequality: 9x <= 45
Divide both sides by 9: x <= 5. The inequality 9x + 5 <= 50 represents the fact that the total cost of Brianna's order (the cost of the books plus the shipping charge) should not exceed the amount of her gift certificate, which is $50.
We subtracted 5 from both sides to isolate the term 9x and then divided by 9 to solve for x, which represents the number of books she can buy. The solution, x <= 5, indicates that Brianna can buy up to 5 books without going over her gift certificate amount.

Answers
The 95% confidence interval for a group of international students mean monthly spending budget is around $1,095.50 and $2,129.50, rounded to the closest penny.
The data in this question include a monthly budgeted amount of $1,612.50 for student expenditures, a standard deviation totaling $1,179.64, as well as a sample size of 20 foreign students.
The z-score of 1.960 with 95% confidence is based on a table of typical normal probability for positive z-scores. Our confidence interval's lower and upper bounds are as follows, where μ is the mean, σ is the standard deviation, and n is the sample size:
Lower limit: µ - (z × (σ ÷ √n))
µ - (z × (σ ÷ √n))
= 1612.5 - (1.960 × (1179.64 ÷ √20))
= 1095.49
Upper limit: µ + (z × (σ ÷ √n))
µ + (z × (σ ÷ √n))
= 1612.5 + (1.960 × (1179.64 ÷ √20))
= 2129.50

f(n) = n² + 20
The first 3 terms of the sequence is when n = 1, 2 and 3

(b.i) The number of miles driven in which the two options cost the same is 150 miles.
(b.ii) If Alonzo drive more than 150 miles, the option that will cost less is option B.
What option cost more?`If Alonzo drives the rental car 75 miles, the option that cost more is calculated as follows;
From the given graph, we can infer the following;
at 75 miles option A costs 35 dollars
at 75 miles option B costs 50 dollars
The difference between the two cost is calculated as follows;
= 50 dollars - 35 dollars
= 15 dollars
So option B cost more than option A at 75 miles with a sum of 15 dollars.
The number of miles driven in which the two options cost the same is obtained from the point of intersection of the two lines.
= 150 miles
If Alonzo drive more than this mile (150 miles), the option that will cost less is option B.

There are 100 multiple-choice questions on the exam, each having responses a,b,c,d. Suppose a student guesses the answer to each question and all the guesses are independent. If the student needs at least 40 questions to pass, what is the probability that the student passes?
Answers
The probability of passing by summing P(X) for X = 40 to 100.
P(pass) = P(40) + P(41) + ... + P(100)
To calculate the probability that the student passes, we need to consider the different scenarios that lead to passing.
The student needs at least 40 questions to pass. Let's calculate the probability of passing for each possible number of correct answers (40, 41, 42, ..., 100) and sum them up.
The probability of guessing a correct answer for each question is 1/4 since there are four choices (a, b, c, d). The probability of guessing an incorrect answer is 3/4.
Let P(X) be the probability of getting X correct answers. The probability of passing is the sum of P(X) for X ranging from 40 to 100.
P(X) = (100 C X) * (1/4)^X * (3/4)^(100-X)
Using these probabilities, we can calculate the probability of passing by summing P(X) for X = 40 to 100.
P(pass) = P(40) + P(41) + ... + P(100)
Performing the calculation yields the probability that the student passes the exam.

The line of best fit for a data set is y=1. 1x+3. 4. Find the residual for each of the coordinate pairs, (x,y). A. (5,8. 8)
Answers
Based on the line of best fit given, the residual for each coordinate is A. - 0.1 B. 3.8 C. 0.32 D. 0.
The line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. It a straight line drawn such that it minimizes the distance between it and some data. The line of best fit is used to express a relationship in a scatter plot of different data points.
A residual refers to a measure of how well a line fits an individual data point and is the vertical distance. The residual for each observation or coordinate is the difference between predicted values of y (dependent variable) and observed values of y. Hence, based on the line y = 1.1x + 3.4, for each coordinate,
A. (5,8.8)
The actual of y = 8.8
The predict value of y = 1.1(5) + 3.4 = 8.9
Residual = actual y – predicted y = 8.8 – 8.9 = - 0.1
B. (2.5, 9.95)
The actual of y = 9.95
The predict value of y = 1.1(2.5) + 3.4 = 6.15
Residual = actual y – predicted y = 9.95 - 6.15 = 3.8
C. (0, 3.72)
The actual of y = 3.72
The predict value of y = 1.1(0) + 3.4 = 3.4
Residual = actual y – predicted y = 3.72 – 3.4 = 0.32
D. (1.5, 5.05)
The actual of y = 5.05
The predict value of y = 1.1(1.5) + 3.4 = 5.05
Residual = actual y – predicted y = 5.05 - 5.05 = 0

$4.50 each, carnations cost $3.00 each, and lilies cost $2.50 each. There are 20
more lilies than roses. The total of the order came to $1,080.00. How many of each
type of flower were ordered? Write a system of equations that represents the
scenario.
Answers
Answer:
Roses = x = 100
Carnations = y = 110
Lilies = z = 120
Step-by-step explanation:
Roses = $4.50
Carnations = $3.00
lilies = $2.50
Total flowers ordered = 330
Total cost = $1,080
Let
Roses = x
Carnations = y
Lilies = z
x + y + z = 330
4.50x + 3y + 2.50z = 1080
There are 20
more lilies than roses
z = x + 20
Substitute z = x + 20 into the equations
x + y + (x + 20) = 330
4.50x + 3y + 2.50(x + 20) = 1080
x + y + x + 20 = 330
4.50x + 3y + 2.50x + 50 = 1080
2x + y = 330 - 20
7x + 3y = 1080 - 50
2x + y = 310 (1)
7x + 3y = 1030 (2)
Multiply (1) by 3
6x + 3y = 930 (3)
7x + 3y = 1030 (2)
Subtract (3) from (2)
7x - 6x = 1030 - 930
x = 100
Substitute x = 100 into (1)
2x + y = 310
2(100)+ y = 310
200 + y = 310
y = 310 - 200
= 110
y = 110
Substitute the value of x and y into
x + y + z = 330
100 + 110 + z = 330
210 + z = 330
z = 330 - 210
= 120
z = 120
Roses = x = 100
Carnations = y = 110
Lilies = z = 120
