❀ Here, We are given relation from A to B [ Suppose ] & We have to identify whether they are function or not from the relation A to B.
{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 )}⇢ This is a function from A to B because every element of Set A has unique image in set B.
{( 0,0 ) , ( 1 , 1 ) , ( 1 , -1 ) , ( 4 , 2 ) , ( 4 , -2 ) }⇢ This is not a function because two of the elements of Set A ( 1 & 4 ) are associated to elements -1 , 1 & 2 , -2 respectively of Set B
{ ( 2 , 1 ) , (2 , 2 ) , (2 , 3 ) , (2 , 4 ) , (2 , 5 )⇢ This is not a function because the element of Set A ( 2 ) is associated to all the elements of Set B.
{ ( 1 , 5 ) , ( 2 , 4 ) , ( 3 , 3 ) , (2 , 2 ) , ( 1 , 1 )⇢ This is not a function because the elements of Set A ( 1 & 2 ) are associated to elements ( 5 , 1 & 4 , 2 ) of Set B respectively.

♨ Q. What is function ? How can we identify whether the given relation is a function ?
⟶Function is a special type of relation. Function is the refinement of relation. In a relation from A to B , every element of Set A has only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.

Answer: try mat way
Step-by-step explanation:
In order to test for the significance of a regression model involving 14 independent variables and 255 observations, the numerator and denominator degrees of freedom (respectively) for the critical value of F are:_____.
a. 14 and 255.
b. 255 and 14.
c. 13 and 240.
d. 14 and 240.
Answer:
d. 14 and 240.
Step-by-step explanation:
Given that
The regression model involving 14 independent variables and 255 observations
We need to find out the numerator and denominator freedom degrees
k = 14 regression variable
= n - k - 1
= 255 - 14 - 1
= 240 residuals
df=14,240
Now The degrees of freedom for F -critical is
F_{k,n-k-1}=F_{14,240}
So, The df of the numerator is 14 and df of the denominator is 240

Multiply by 2
Try:
20+21=41
Multiply by 2:82
Answer:
82 meters
Step-by-step explanation:

P=20+20+21+21
P=2x20+2x21
P=2x(20+21)
P=2x41

The smith family is shopping for a new car
Answer:
Sample response: The Smith family has 2 choices to make, color and style. By the fundamental counting principle, the product of the number of choices of color and style must equal 8. So, there could be 1 color and 8 style choices, 2 colors and 4 styles, 4 colors and 2 styles, or 8 colors and 1 style.

The component form of a vector is (-7.765,28.978) What is the direction angle for the vector measured counterclockwise from the positive x-axis?
Answer:
The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.
Step-by-step explanation:
Let be [tex]P(x,y)[/tex] a point containing the components of a vector, the direction angle for the vector regarding origin ([tex]\theta[/tex]), in sexagesimal degrees, is determined by the following formula:
[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (1)
Where:
[tex]x[/tex] - x-coordinate of the point P.
[tex]y[/tex] - y-coordinate of the point P.
Let consider that [tex]P(x,y) = (-7.765, 28.978)[/tex]. After a quick inspection, we note that vector stands in the 2nd Quadrant ([tex]x < 0 , y > 0[/tex]). Then, the direction of the angle with respect to the positive x semiaxis is:
[tex]\theta = \tan ^{-1} \left(\frac{28.978}{-7.765} \right)[/tex]
[tex]\theta \approx 105.001^{\circ}[/tex]
The direction angle for the vector measured clockwise from the positive x-axis is approximately 105.001°.
Angle the given vector makes with the positive x-axis when measured counterclockwise is required.
The direction of the angle for the vector measured counterclockwise from the positive x-axis is 105°. The calculations have been shown below by using the concepts of vector.
VectorsThe given vector is (-7.765,28.978)
The angle is found by the formula
[tex]\theta=\tan^{-1}\dfrac{y}{x}[/tex]
Here,
y = 28.978
x = -7.765
Substituting the given values we get
[tex]\theta=\tan^{-1}\dfrac{28.978}{-7.765}=-74.99=-75^{\circ}[/tex]
So, the required angle is
[tex]180-75=105^{\circ}[/tex]

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms
Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers
Answer:
As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.
Step-by-step explanation:
A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

Answer:
4x^11 [tex]\sqrt{5}[/tex]
Step-by-step explanation:
You can simplify the 20 inside of the radical by finding its prime factors. 20 has 3 prime factors: 5, 2, and 2. Since the 2 occurs twice, we can cancel out those 2s in the 20 itself and put a singular 2 outside of the radical. It is essentially turning [tex]\sqrt{20}[/tex] into 2[tex]\sqrt{5}[/tex]. Since we now have simplified that 20, the entire equation is now 4x[tex]\sqrt{5x^2^0}[/tex]. We can root x^20 to get x^10, and [tex]\sqrt{5}[/tex] stays that way. The entire equation is now 4x[tex]\sqrt{5}[/tex]x^10, which can be simplified to [tex]4x^1^1\sqrt{5}[/tex].

Help please !!! Need help
Answer:
234
Step-by-step explanation:
From the given information :
The 4th term, a4
a1 = 3
a2 = 4(a1) + 2
a2 = 4(3) + 2 = 14
a3 = 4(a2) + 2
a3 = 4(14) + 2
a3 = 58
a4 = 4a3 + 2
a4 = 4(58) + 2
a4 = 232 + 2
a4 = 234
