Tammy conducted a survey to find the favorite subject of the students at her school. She asked 25 students from her math class w
almond37 [142]
Tammy's sample may not be considered valid because, on the first hand, it is said that she only asked students from her " Math Class". 
If she wants to have a survey to find out the favorite subject of the students at her school, she must conduct a survey involving all the students in her school, not just in her class. What she did is just subjective. She should use a tally listing the different subjects and compare the number of students per subject. This way, she can have an objective representation of the least liked subjects and the most liked subjects of the students on her school.
Illustrating her survey through statistics may be more reliable and valid because it shows frequencies in which she can calculate easily and accurately the percentage of  the number of students per subject, in a more objective manner.

ms. eskew's class had a class average of 77 % on their math test. how would this be written as a ratio? a. 23:100 b. 77:100 c. 5
valina [46]
Writing in percentages is actually writing a fraction with 100 on its denominator.
By doing so, we can easily compare data.
For example 1/2 may be written as 50/100 and it is denoted by 50%.

So, in your question, 77% means 77/100.
Since fractions represent ratios, writing in ratio form, we get 77:100. The answer is (b)77:100

The students at a community center are participating in a bike riding fundraiser at a local park. A local company is donating $1
Oksi-84 [34.3K]

Answer:

This can not be properly answered, because we do not have the length of each trail.

The first step here will be find the length, in miles, for each of the four trails.

As students choose all four trails, the number of miles that each student will bike is equal to the addition of the lenght of the four trails.

Suppose this number is N.

So each student bike N miles, and the company donates $1.75 per mile. Then the amount of money that a single student is N times $1.75, or N*$1.75

Sara works for 40 hours a week. She attends meetings for 0.28 of the time she is working. How much time does Sara spend at meeti
Roman55 [17]

Answer:

11.2 hours or 11 hours 12 minutes

Step-by-step explanation:

In this question, we are to calculate the amount of time spent by Sara in attending meetings weekly.

In the question, we are made to understand that she attends a meeting at a rate of 0.28 multiplied by the total amount of time she works.

To get the time she attends the meeting, we only need to multiply the decimal by the number of hours she works

Mathematically that would be 0.28 * 40 = 11.2 hours per week

We might take it further to get the time in the format of hours and minutes. That would be 0.2 * 60 yo convert the hours to minutes. This gives 12 minutes .

She attends meeting 11 hours 12 minutes per week
