Sam conducted a survey to find out the favorite weekend activity of the students in his middle school. He asked 20 of his classmates. He found out that the favorite weekend activity of his middle school is playing video games because 75% of the students he surveyed liked to play video games. Explain why Sam’s sample may not be valid. Provide 2 or 3 sentences of explanation with facts to support your answer. How could Sam improve his survey to be more representative of his school?
Answer:
So, Sam only asked 20 people in his entire middle school. That is a very small fraction of the amount of kids attending that school. He cannot say that video games is 75% of the entire school's favorite weekend activity if he only asked 20 people. To get a better, more valid result, he should ask around 100+ kids.

Please help me and please don't answer if you're not a 100% sure!
The answer choices are
A. 93
B. 31
C. 69
D. 300
Answer:
A
Step-by-step explanation:
We obviously can take out D and B, as roses are 31% while carnations are 19%. Since roses have a larger percentage, it obviously can't be less than carnations but 300 is beyond the logical answer. This leaves us with 69 or 93. 19% is 57, so a 12 percent rise will not equal an increase of only 12 flowers. Therefore, without even any calculations, I can confidently tell you that your answer is A.

Tony rode his bicycle 3 7/10 miles to school. What is this distance written as a decimal?
Answer:
The distance written as a decimal is 3.7
To write 3 7/10 miles as a decimal, multiply the whole number by the denominator and add the numerator, then write the result over the denominator. Simplify the fraction if possible.
Explanation:To write the distance in decimal form, we need to convert the mixed number to a decimal. The given distance is 3 7/10 miles. To do this, we multiply the whole number, 3, by the denominator, 10, and add the numerator, 7. So, 3 multiplied by 10 plus 7 equals 37. Then, we write 37 over the denominator 10, giving us 37/10. Finally, we can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which in this case is 1. Dividing 37 by 1 gives us 37, and dividing 10 by 1 gives us 10. Therefore, the distance of 3 7/10 miles can be written as the decimal 3.7 miles.

over the weekend statton and Taylor drove to Montana to go hunting. now they're preparing to go home. Tyler needs gas for his jeep, which gets 30 miles per gallon for gas mileage. When he stops at the gas station, he already has 8 gallons of gas in his tank. he buys more gas for $1.50 per gallon
If Tyler spends $16.50 on gas, what is the total distance the boys could travel? round, if necessary, the nearest tenth.
Answer:
Step-by-step explanation:
Givens
His tank contains 8 gallons
He spends 16.50 on gas
A gallon of gas costs 1.50 dollars
Millage = 30 mpg
Find the gas added.
Total gas (in gallons) added = amount spent / cost per gallon
Total gas (in gallons) added = 16.50 / 1.50
Total gas (in gallons) added = 11 gallons.
Find the total number of gallons in his tank.
Total = what was there + What he bought.
Total = 8 + 11
Total = 19 gallons.
Find the distance he can travel
Total distance = gallons * miles / gallon
Total distance = 19 * 30
Total distance = 570 miles.
Tyler and Statton could potentially travel a total distance of 570 miles with the amount of gas they have.
Explanation:The question is asking for the total distance that the boys could travel on the bought gas. Tyler bought $16.50 worth of gas at $1.50 per gallon, which means he bought 11 gallons ($16.50/$1.50). Tyler initially had 8 gallons of gas in his tank. Therefore, he now has a total of 8 + 11 = 19 gallons of gas. His Jeep gets 30 miles for every gallon of gas. Therefore, the total distance they can travel is 19 gallons * 30 miles/gallon = 570 miles.
So, "Tyler and Statton could potentially travel 570 miles with the gas in the tank".

Answer:
I think its 70
Step-by-step explanatio
Hope this helps!
Answer:
A. 140
Step-by-step explanation:
We have been given an image of a circle. We are asked to find the value of z.
Upon looking at our given circle we can see that z is the intercepted arc to the inscribed angle that measures 70 degrees.
We know that measure of intercepted arc of a circle in two times the measure of inscribed angle.
Using inscribed angle theorem we can set an equation as:
[tex]z^{\circ}=2\times 70^{\circ}[/tex]
[tex]z^{\circ}=140^{\circ}[/tex]
Therefore, the value of z is 140 and option A is the correct choice.

Add 5/6 + 3/4 + 2/3 simplify the answer write it as a mixed number if possible
Answer: 27/12 or 2 3/12
Step-by-step explanation: First off we would need to find a common denominator, so all the fractions could be added together easily, and we could use a denominator of 12 because 6 times 2 equals 12, 4 times 3 equals 12, and 3 times 4 equals 12. So 5/6 would become 10/12, 3/4 would become 9/12, and 2/3 would become 8/12. So adding them all together would give you a sum of 27/12 or 2 3/12. Hope this helped!

a teacher read part of a book to class. The graph shows the number of pages read by the teacher over the next several days. Find and interpret the rate of change and the initial value.
The rate of change on a graph represents how fast or slow the changes are happening, while the initial value is the starting point. To find these on a graph, you determine the slope of the line for the rate of change, and look at the intercept on the y-axis for the initial value. These values give us insights into the reading pace and starting point of the teacher.
Explanation:The rate of change in a graph represents the slope of the line. It tells us how the quantity being measured changes over time. If the graph is a straight line, the rate of change is constant, but if the line is curved, the rate of change varies.
To find the rate of change, you need to select two points on the graph and find the difference in the page numbers divided by the difference in the corresponding time points. That is (pages end - pages start) / (time end - time start).
The initial value is the point where the teacher started reading the book. This point is seen as the intercept on the y-axis of the graph.
The interpretation of these values would be that the rate of change tells us how quickly the teacher is reading the book, and the initial value tells us at what page number the teacher started reading.

Initial value: The teacher initially read 150 pages. Rate of change: The teacher read 100 pages per day. The graph shows that the teacher is reading at a consistent pace and is making good progress on the book.
The initial value of the graph is the y-intercept, which is 100 pages. This means that the teacher had already read 100 pages before the graph starts.
The rate of change of the graph is the slope, which is calculated as (change in y) / (change in x). In this case, the slope is (750 - 100) / (5 - 1) = 130 pages/day.
This means that the teacher is reading 130 pages per day.
Interpretation:
The teacher is reading at a rate of 130 pages per day. This means that each day, the teacher is reading 130 more pages than the previous day.
The initial value of 100 pages means that the teacher had already read a significant portion of the book before the graph starts. It is possible that the teacher was reading ahead, or that the teacher was reading a chapter book to the class and had already finished the first chapter.
Overall, the graph shows that the teacher is reading at a consistent pace and is making good progress on the book.

Jerry is driving at a steady speed on an inter-state highway. 2.5 hours after he starts, he notes that he has driven 150 miles. After 5.5 hours, he notes that he has covered 330 miles.
Which graph shows how his distance covered varies with time?
A)B)C)D)
Answer:
graph a
Step-by-step explanation:
you have to look at the numbers carefully and that was the only graph that showed everything
Answer:
Step-by-step explanation:
Jerry is driving at a steady speed on an highway.
After 2.5 hours he has driven = 150 miles.
speed = [tex]\frac{150}{2.5}[/tex] = 60 miles/hour
then after 5.5 hours he has covered 330 miles.
speed = [tex]\frac{330}{5.5}[/tex] = 60 miles/hour
Total time he has driven = 2.5 + 5.5 = 8 hours
total distance he covered = 150 + 330 = 480 miles.
Therefore, after 2.5 hours he covered 150 miles and after 8 hours he covered 480 miles with an steady speed of 60 miles/hour.
Graph A shows his constant speed and his distance covered varies with time.

Work out the base of a square with area, A = 4cm2.
Answer:
each side of the square is 2cm
To find the base of a square with an area of 4 cm², we take the square root of the area. The base of the square is 2 cm because the square root of 4 is 2.
To work out the base of a square with an area of 4 cm², we note that a square's area is calculated by multiplying one of its sides by itself, which is represented as side length² or a². Given that a square's area is 4 cm², we set up the equation a² = 4 cm². Solving for a, we take the square root of both sides of the equation. The side length a is thus 2 cm, since the square root of 4 is 2. Therefore, the base of the square is 2 cm.
