When is there no solution to a compound inequality is it AND or OR
Answer:
The solution could begin at a point on the number line and extend in one direction. 3. In cases where there is no overlap between the two inequalities, there is no solution to the compound inequality.

Kareem says that the ratio 4 : 1 is equivalent to the ratio 12 : 9 because 4 1 8 5 12 and 1 1 8 5 9. Is Kareem correct? Explain how you know.
[tex]\bf Step-by-step~explanation:[/tex]
Kareem's statement: 4:1 is equal to 12:9. Let's see if this is correct.
[tex]\bf Step ~1:[/tex]
We have to simplify the ratios. Since 4:1 is already simplified, we do not have to do anything with it. 12:9 could be simplified. To do so, we need to find the greatest common factor (GCF) of both numbers. The GCF of 12 and 9 is 3. Since 3 is the GCF for both numbers, we divide them by 3.
[tex]\bf 12 /3=4\\9/3=3[/tex]
First number: 4
Second number: 3
Ratio: 4:3
[tex]\bf Step~2:[/tex]
We compare the ratio 4:3 to 4:1. Since they have different values, they are not equivalent to each other.
[tex]\large\boxed{\bf Our~final~answer: ~Kareem~is~wrong.}[/tex]
[tex]\bf {Explanation~in~Step~1}[/tex]
4 : 1 and 12 : 9 are not equivalent
Kareem is wrong
Correct question:
Kareem says that the ratio 4:1 is equivalent to the ratio 12:9 because
4 + 8 = 12 and 1 + 8 = 9. Is Kareem correct? Explain how you know
4 : 1 is in its simplest form already
12 : 9
= 12/9
= 4/3
= 4 : 3
Therefore,
4 : 1 and 12 : 9 are not equivalent
Kareem is wrong based on his assumption that 4 + 8 = 12 and 1 + 8 = 9

Simpif the expression
Answer:
-8b - 32
Step-by-step explanation:
Distribute the 8 to each term in the parentheses:

An academic advisor calculated the mean GPA for college freshmen to be 2.33, with a standard deviation of 1.06. The advisor knows that there is a relationship between high school GPA and freshman-year GPA. If the advisor uses each student's high school GPA to predict his/her freshman-year GPA, what happens to the average error in prediction (relative to not using high school GPA to predict freshman-year GPa.
Answer:Average error will be less
Step-by-step explanation: Prediction error refers to the difference between the the actual and predicted value of an observation. Using correlation analysis or study, The level or degree of correlation or relationship between two measured variables usually determines the variation or measure of the prediction error. If there is no relationship or correlation between two measured variables, if such model is used to make prediction, the average prediction error will be very high. However, since it is stated that there exist a relationship between high school GPA and Freshman-year GPA, then making prediction based on this assertion will lessen the average prediction error.
2. Kate is a professional musician. She wants to make an essential purchase of an upgraded used bass guitar
for her work. She found the following prices for the same make and model bass guitar from various sellers:
| $699.$599, $699.$680, $590, $720, $650, $800
What is the mean price? Round your answer to the nearest cent.
What is the median price?
What is the mode price?
Answer:
a. What is the mean price? Round your answer to the nearest cent. $679.63
b. What is the median price? $689.50
c. What is the mode price? $699
Step-by-step explanation:
The mean price, rounded to the nearest cent is $679.63, the median price is $689.5 and the mode price is $699.
What is Mean, Median and Mode?The mean is the ratio of the sum of all numbers and total numbers in the list. The median is the middle value in a list ordered in ascending order. The mode is the most frequently occurring value on the list.
In our question, given data:
$699, $599, $699, $680, $590, $720, $650, $800
Mean is found by dividing by sum all the prices and then divided by total terms.
Sum all prices = ($699 + $599 + $699 + $680 + $590 + $720 + $650 + $800) = $5437
Mean = [tex]\frac{5437}{8}[/tex] = $679.625
The round of mean value to the nearest cent is $679.63.
To find median, arrange the data list in ascending order and then find the middle value. Since in our data list, there are 8 terms (even). Therefore take average of the two middle values to find median.
Ascending order ⇒ 590, 599, 650, 680, 699, 699, 720, 800
Midian = [tex]\frac{680 + 699}{2}[/tex] = $689.5
Mode is the most frequently occurring value in the data list, in our data list, 699 comes twice.
∴ Mode = $699
Hence Mean = $679.63, Midian = $689.5, Mode = $699.

Answer:
I will attach the missing drawing with the answer.
9.b)
Plane JKM

Step-by-step explanation:
The drawing for this question is missing. I will attach it with the answer.
9.a) Plane JKL is not an appropriate name for the plane because all of three points lie in the same line.
Through a line pass infinite planes. The plane JKL doesn't define a unique plane. That's why plane JKL isn't an appropriate name for the plane.
9.b) We can name the plane using three points that don't lie in the same line.
Three possible names for the plane are :
Plane JKM

In a class of 25 students, 24 of them took an exam in class and 1 student took a make-up exam the following day. The professor graded the first batch of 24 exams and found an average score of 74 points with a standard deviation of 8.9 points. The student who took the make-up the following day scored 64 points on the exam. what is the new average
Answer:
The value is [tex]\mu_n = 73.6[/tex]
Step-by-step explanation:
From the question we are told that
The total number of students is [tex]N = 25[/tex]
The number of student that took exam in class is n = 24
The number that took make up exam is k = 1
The average score of the first 24 students is [tex]\mu = 74[/tex]
The standard deviation is [tex]\sigma = 8.9[/tex]
The average score of the student who took make up test is [tex]\= x = 64[/tex]
Generally the new average is mathematically represented as
[tex]\mu_n = \frac{( n * \mu ) + \= x }{N}[/tex]
[tex]\mu_n = \frac{( 24 * 74 ) + 64 }{25}[/tex]
[tex]\mu_n = 73.6[/tex]

A guy wire supports an antenna tower, as shown at the right. The bottom of the wire is secured in the ground 30 feet from the base of the tower. The top of the wire is secured to the tower at a height of 30 feet above the ground. How long is the wire? Round your answer to the nearest tenth of a foot.
Answer:
The wire is approximately 42feet long
Step-by-step explanation:
We can mentally sketch out the shape that is formed between the guy wire and the antenna tower. This is simply a right-angled triangle with the opposite side being the height of the antenna (30 feet). The adjacent side is the distance on the ground between the point where the wire was fastened and the base of the antenna.
The hypotenuse side is the length of the wire we are looking for.
Parameters are given as:
Opposite : 30ft
Adjacent: 30ft
Hypotenuse: x feet
The hypotenuse = [tex]\sqrt{opp^2 + adj^2}[/tex]
Hypotenuse =[tex]\sqrt{30^2+ 30^2} \approx 42ft[/tex]
