Step-by-step explanation:
Many businesses and organizations insist that official communications use professional-looking fonts, such as Times New Roman. Fonts characterized as less professional, such as Comic Sans, should be avoided. A student would like to determine if font choice makes a difference in the average grade on a typed response in English classes. There are currently four English classes available from which the student can collect data, and each class has a similar writing assignment. The student considers two methods for collecting data.
Method A: At the start of the assignment, students choose a font, either Times New Roman or Comic Sans, and then complete the assignment.
Method B: At the start of the assignment, students are randomly assigned one of two fonts, either Times New Roman or Comic Sans, and then complete the assignment.
In both methods, the teachers grade the papers received, and the mean grade for each font is determined.
Which method describes an experiment?
Method A is an experiment because the students choose their own font.
Method B is an experiment because the students are randomly assigned a font.
Both methods describe experiments because both fonts are used on the assignment.
Neither method describes an experiment because a third font should be included for comparison.
Answer:
B) Method B is an experiment because the students are randomly assigned a font.
Step-by-step explanation:
correct on edge
The method that describes an experiment is B) Method B is an experiment because the students are randomly assigned a font.
What is an Experiment?This refers to the scientific procedure that is undertaken in order to make a discovery or prove a theorem.
Hence, there are two methods available for use for students who are randomly assigned fonts Method A has to do with the intentional selection, and Method B has to do with random selection.
As a result of this, we can state that Method B is an experiment because the students are randomly assigned a font.

Why is the atmosphere heated unevenly by the sun
Answer:
The answer is due to uneven heating of the Earth by the Sun.Since the center of the Earth gets more sunlight, it is consistently hotter than other parts of the Earth. Sunlight hits the equator with a more direct angle leading to increased temperatures. When air is hot, it rises.

A graph is the plot of a function or a proportion thus (1,18) represents the number of cookies made by using 1 cup of flour is 18.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
As per the given graph of the number of cookies and cups of flour.
The coordinate of a point is (x,y) and here x-axis is the cups of flour and the y-axis is the number of cookies.
Since x = 1 so cups of flour are 1.
Since y = 18 so the number of cookies is 18.
Hence "A graph is the plot of a function or a proportion thus (1,18) represents the number of cookies made by using 1 cup of flour is 18".

Step-by-step explanation:
Given inequality is:
y>-5x+3
In order to find which point is solution to the given inequality we'll put the point one by one in the inequality. If the point satisfies the inequality, then the point is the solution of the inequality.
Putting (0,3) in inequality

In a probability experiment, Craig rolled a six-sided die 64 times. The die landed on a number greater than three 39 times. What is the ratio of rolls greater than three to rolls less than or equal to three?
A.
B.
C.
D.
Answer:
The ratio is 34/22, or in simplest form, 17/11.
Step-by-step explanation:
We write the ratio with the number of rolls greater than three on top and the number of rolls less than or equal to 3 on bottom:
34/(56-34)
We have to subtract 34 from 56 to find out how many rolls were less than or equal to 3.
34/22
Both are divisible by 2, so we have 17/11.

Subtraction. In order of operations, parenthesis comes first. Since the subtraction term is in the parenthesis, you would do that first. Then it's exponents, multiply, divide, add, and subtract. In the case that there are more than one multiplication/division operation, you would do it in the order from left to right. Same for subtraction/addition.
