answer:
1
Step-by-step explanation:
#'s between zero and two = one
the only number between 0 and two is 1
x = 1 y = 1 z = 1
the average value of the sum of the squares of x, y and z = 1
1, 1, 1
the average is 1

The values of the central tendencies are as follows;
The mean of Class 1 is 78.83.
The median of Class 1 is 88
The mean of Class 2 is 79.42
The median of Class 2 is 85.50
The mean of Class 3 is 79.42
The median of Class 3 is 78
The standard deviation of Class 1 is 18.81
The standard deviation of Class 2 is 16.15
The standard deviation of Class 3 is 12.70.
How to find the mean and median?Mean is the average of a set of numbers.
Mean = sum of numbers / total number
Mean of Class 1 = (45 + 50 + 55 + 68 + 77 + 86 + 90 + 90 + 90 + 95 + 100 + 100) / 12 = 78.83
Mean of Class 2 = (40 + 64 + 65 + 70 + 80 + 84 + 87 + 88 + 90 + 90 + 95 + 100) / 12 = 79.42
Mean of Class 3 = (55 + 65 + 70 + 75 + 75 + 76 + 80 + 80 + 88 + 90 + 99 + 100) / 12 = 79.42
Median is the number that is at the center of the dataset that is arranged in either ascending or descending order.
Median of Class 1 = (86 + 90) / 2 = 88
Median of Class 2 = (84 + 87) / 2 = 85.50
Median of Class 3 = (76 + 80) / 2 = 78
Standard deviation is used to calculate the average variation of a dataset.
Standard deviation = √((x - μ)²/σ)
Where:
x = number in the dataset
u = mean
n = total numbers in the dataset.
Standard deviation of Class 1 = 18.81
Standard deviation of Class 2 = 16.15
Standard deviation of Class 3 = 12.70

Identify the axis of symmetry of the parabola.
A. y = 1
B. x = 1
C. y = −1
D. x = −1
Answer:
D. x = −1
Step-by-step explanation:
In the graph, the vertex of the parabola hits point (-1,-2). Therefore, the axis of symmetry is x = -1. It is not y = -2, since the parabola opens vertically, not horizontally.
What is the equation of the line shown in this graph?

Answer:
x = 67°
Step-by-step explanation:
angle FGD and angle CGE are vertical angles, meaning that they both have the same value. This concludes that angle FGD must be 23°. Now, we have to find angle x. We know that angle x and angle FGD are complementary, meaning they sum to 90°. Therefore, x = 90° - 23° = 67°.
Given the following PARALLELOGRAM, find the measure of each angle below.
Answer:
m∠BEC = 65°
m∠DEC = 115°
m∠DAE = 78°
m∠ECD = 40°
m∠BAD = 118°
m∠ADC = 62°
Step-by-step explanation:
m∠BEC = 65°
Opposite angles formed by intersecting lines are congruent
m∠DEC = 180 - 65 = 115°
A straight line has a degree measure of 180
m∠DAE = 78°
Opposite interior angles of two parallel lines cut by a transversal are congruent
m∠ECD = 180 - [m∠DEC + 25] = 40°
Sum of angles inside triangle ECD has a measure of 180
m∠BAD = 78 + m∠ECD = 118°
Opposite angles of a parallelogram are congruent
2(m∠BAD) + 2(m∠ADC) = 360
118 + m∠ADC = 180
m∠ADC = 62°
Sum of angles inside a parallelogram = 360°
Item 4 Evaluate. [(1 1/4−3/4)⋅(−2/3)3]÷(−4) What is the value of the expression? Enter your answer as a simplified fraction in the box.
Answer:
1/27
Step-by-step explanation: I took the quiz and the right answer is 1/27
The value of the given expression would be 0.25 which is simplified by using the PEMDAS rule in the expression.
What is PEMDAS rule?The Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction rule is abbreviated as PEMDAS. This rule is used to answer the problem correctly and properly.
The given expression would be below as:
⇒ [(1 1/4−3/4)⋅(−2/3)3]÷(−4)
Using the PEMDAS rule in the above expression,
⇒ [(5/4−3/4)⋅(−2/3)3]÷(−4)
Apply the subtraction operation,
⇒ [(2/4)⋅(−6/3)]÷(−4)
Reduce the fractions, and we get
⇒ [(1/2)⋅(−2)]÷(−4)
Cancel out the terms of 2 to each other
⇒ (−1)÷(−4)
Cancel out the negative sign to each other
⇒ 1 / 4
Apply the division operation to get
⇒ 0.25
Therefore, the value of the given expression would be 0.25 which is evaluated.

URGENT, WILL GIVE BIG BRAIN OR WHATEVER ITS CALLED LOL
For every 1000 hits a YouTub channel gets it makes £2 from ad revenue. a How many hits are required to make £21?
Answer: 10,500 hits
Step-by-step explanation:
I WANT BIG BRAIN! I WANT BIG BRAIN AHAHHHHHHH!!!!!!!
ok there are a number of ways to go about this
it is unclear whether or not the YT content creator will get one pound for 500 hits
i honestly dont know but i am going to assume it will
1000 times 20 (we are plugging in a test variable, 20, here)
so lets say we have 20,000 hits
lets divide that by 1000 and we get 20. 20 times 2 is 40 pounds so obviously thats too much
lets try 1000 times 10
so we have 10 times 2 and thats 20 pounds. we are closer
10,500 hits
(i put in 500 because half of 1000 is 500 and that will give you one pound instead of two)

13. A linear cost function is C(x)= 28.37x +5,580, where x represents the number of units produced. What is the cost
of producing one more item if 75 are currently being produced? Round your answer to the nearest cent.
a. $7,736.12
b. $28.37
c. $5,580.00
d. $5,608.37
e. $75.00
9514 1404 393
Answer:
b. $28.37
Step-by-step explanation:
In the cost function, x is the number of units. The derivative of the cost function with respect to x will tell the incremental cost of producing one more unit. That derivative is a constant, $28.37 per unit, so the cost of producing one more unit is $28.37 at any production level.
