The test scores for 10 students were: 74, 81, 39, 74, 85, 80, 100, 92, 74, and 85. What
is the mode?
Answer:
74
Step-by-step explanation:
"The mode is the value that appears most often in a set of data values."
So, if we look at this data, we can conclude that the mode is 74 because 74 appears 3 times (with 85 being second at twice).
74, 81, 39, 74, 85, 80, 100, 92, 74, and 85

Answer:
25 ft^2
Step-by-step explanation:
In direct variation, if y varies directly with x, then the equation has the form
y = kx,
where k is the constant of proportionality. y is proportional to x.
Let's call the area y and the distance x.
Here, the area varies with the square of the distance, so the equation has the form
y = kx^2
Here, y is proportional to the square of x.
We can find the value of k by using the given information.
y = kx^2
When x = 20 ft, y = 16 ft^2.
16 = k(20^2)
k = 16/400
k = 1/25
The equation of the relation is:
y = (1/25)x^2
Now we use the equation we found to answer the question.
What is y (the area) when x (the distance) is 25 ft?
y = (1/25)x^2
y = (1/25)(25^2)
y = 25
Answer: 25 ft^2

Answer:
H: 119 degrees.
G: 61 degrees.
M: 54 degrees.
K: 126 degrees.
Step-by-step explanation:
Please answer the question step by step!
Answer:
Step-by-step explanation:
See the figure below.
This is how you graph directly from the equation in the slope-intercept form (y = mx + b) without having to create a table of x and y values.
The equation is
y = -2/3 x + 1
Compare it with
y = mx + b
b = 1
The y-intercept is 1, so mark 1 on the y-axis. (You already did.)
I placed a black dot there.
The slope is m.
m = -2/3
slope = m = rise/run
A slope of -2/3 can be though of as -2 rise and 3 run. That means start from the y-intercept, and go -2 in y (a rise of 2 down) and 3 in x (a run 3 right). Point graphed in red.
Mathematically, -2/3 is the same as 2/(-3), so starting again from the y-intercept, this slope can also be though of as rise of 2 in y (a rise of 2 up) and a run of -3 in x (a run of 3 left). Point graphed in green.
The line is graphed in blue.

Answer: 758,000
Step-by-step explanation:
Expression: 420 x 1,800
Basically just find the number of seconds and since every second 420 items are sold just multiply 420 x number of seconds which is 1,800

Answer:
b,c and d are the answers
Step-by-step explanation:k12
Expressions (B), (C), and (D) are all equivalent to the given expression 1.3−4x−3.7.
What are expressions?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles.An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.)So, the expressions equivalent to 1.3−4x−3.7 are:
Solve: 1.3−4x−3.7
1.3−4x−3.7- 2.4 - 4xNow, calculate for - 2.4 - 4x:
(A) −0.6−4−x:
-4.6 - x ≠ - 2.4 - 4x(B) −4(x+0.6)
- 2.4 - 4x = - 2.4 - 4x(C) −x−x−x−x−2.4
- 2.4 - 4x = - 2.4 - 4x(D) −4x−2.4
- 2.4 - 4x = - 2.4 - 4xTherefore, expressions (B), (C), and (D) are all equivalent to the given expression 1.3−4x−3.7.
