Part B If Ivy conducted her survey of 25
students on a volunteer basis, are the
results representative of the school?
Why or why not?
Answers
Answer:
Step-by-step explanation:
No, the results are not necessarily representative of the school as a whole.
What is the random survey?A random survey is a research technique that is used to gather information from a sample of people or things in a population. The results of a random survey are more likely to be representative of the population as a whole since every member of the population has an equal chance of being chosen to take part in the research.
Given:
Ivy randomly surveys students in her school to learn more about mobile phone password use.
Of 25 respondents, 14 use a password.
If the survey was conducted on a volunteer basis, it is possible that the respondents who chose to participate may have different characteristics or behaviors than those who did not participate.
This could lead to a biased sample that does not accurately represent the entire school population.
Additionally, even if the sample is representative of the school population, a sample size of 25 is relatively small, which can increase the margin of error and make it more difficult to draw accurate conclusions.
Therefore, it is important to consider the limitations of the survey method and sample size when interpreting the results.

Answer: celsius = 5/9 (Fahrenheit - 32)
Step-by-step explanation:
Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)
So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.
Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)
You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.
I hope that makes sense!

Answers
Answer:
60.79 square yards.
Step-by-step explanation:
d = 2r; d = 8.8.
8.8 = 2r
r = 8.8 / 2
r = 4.4 yards.
Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.
4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.
Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

find the coordinates of each figure after the given transformation
Answers
Answer:
A'(-3, -2)
B'(-2, -1)
C'(-2, -2)
Step-by-step explanation:
The translation is (x - 7, y + 1).
That means subtract 7 from the x-coordinate and add 1 to the y-coordinate of each point.
Point A is (4, -3).
Subtract 7 from the x-coordinate 4 to get -3.
Add 1 to the y-coordinate -3 to get -2.
For point A, you get A'(-3, -2) after the translation.
Do the same with points B and C.
B(5, -2) ---> B'(5 - 7, -2 + 1) = B'(-2, -1)
C(5, -3) ---> C'(5 - 7, -3 + 1) = C'(-2, -2)

A bowl holds the 15 pieces of fruit shown below.
If Jasmine correctly writes the fraction of fruit that are apples, which of the following would be the numerator of the fraction?
Answers
Answer:
Step-by-step explanation:
8/15
The fraction representing the number of apples is 8/15 thus, the numerator will be 8.
What is numerator and denominator?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
In another word, if we divide two numbers by each other then the upper word is called the numerator, and the lower word is called the denominator.
As per the given apple lot,
The total number of fruits = 20
The total number of apples = 8
Thus, the fraction will be 8/20 where the numerator will be 8.
Hence "The fraction representing the number of apples is 8/15 thus, the numerator will be 8".

The Solution of the Inequality is y> 2.1.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
Inequality: 2y + 7 > 15.2
Now, simplifying the inequality
2y > 15.2-7
2y > 8.2
y> 8.2 /2
y> 2.1
So, the solution is y>2.1
