Answer:
19.8 years old
Step-by-step explanation:
If Z=(x-μ)/σ where Z=-1.32, σ=3.2, and μ=24, then:
-1.32=(x-24)/3.2
-4.224=x-24
19.776=x
19.8
Therefore, the age of a concert attendee with a z-score of -1.32 is 19.8 years old.

Answer: z = 12
Step-by-step explanation:
Opposite angles are equal.
So...
5z +8 = 4z + 20
Solve for z...
5z = 4z + 12
z = 12

Which set of ordered pairs is a function? {(1,1),(2, 2), (3, 3), (4,4), (5,5)} {(0,0),(1,1),(1, -1),(4,2),(4, -2)} {(2,1),(2,2).(2,3),(2,4),(2,5)} {(1,5).(2.4),(3,3).(2, 2), (1,1)
[tex] \underline{ \underline{ \large{ \red{ \tt{✧ E\: X \: P \: L \: A \: N \: A \: T\: I \:O\: N}}}}} : [/tex]
❀ 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.
[tex] \boxed{ \boxed{ \large{ \purple{ \tt{A \: N \: S \: W \: E \: R: \{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 ) \} }}}}}[/tex]
♨ 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:
12.207
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are legs of the right triangle, c is the hypotenuse.
The hypotenuse squared is equal to the square root of (7^2 + 10^2).
The square root of 149 is around 12.207.
You cannot simplify the square root of 149 so if the question wants it in radical form just input square root of 149.

Find the volume of the sphere need help
Answer:
36pi
Step-by-step explanation:

4/3 x pi x r^3
3 cubed = 27
27 x pi x 4/3
27 x 4/3 = 36

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.

A Sociology student investigated the association between a country's Literacy Rate and Life Expectancy, and then drew the conclusions listed below. Explain why each statement is incorrect. (Assume that all the calculations were done properly.)
a) The $$R^2$$ of 64% means that the Literacy Rate determines 64% of the Life Expectancy for a country.
b) The slope of the line shows that an increase of 5% in Literacy Rate will produce a 2-year improvement in Life Expectancy.
Solution :
The term 'literacy rate' provides the ability of a person who is from a definite age group can read or write.
a). [tex]$R^2$[/tex] does not determine the rate at which the variable explains another, but it explains the amount the amount of variability in one of the variables as explained by the other variable.
b). The slope given provides an expected improvement but it cannot guarantee the improvement. The value may be less or it could be more also.
The regression model provides the prediction and not the actual values.
Kyle and Jorge play for a major league baseball team.
• Kyle has hit x number of home runs this season.
• Jorge has hit 4 times the number of Kyle's home runs.
Together they have hit 45 home runs.
How many home rns has Kyle hit?
The number of home runs hit by Kyle is 9.
Number of home runs by Kyle =x
So, the number of home runs by Jorge = 4x
What is the sum of x and 4x?The sum of x and 4x is 5x.
According to the question, together they have hit 45 home runs.
This means, x+4x=45
5x=45
x=9
So, the number of home runs by Kyle =9
the number of home runs by Jorge =36
Hence, the number of home runs hit by Kyle is 9.

What's the right answer?
Given:
[tex]sinh(f(x))=1+x^2[/tex]
To find:
The value of f'(x).
Solution:
Formulae used:
[tex]\dfrac{d}{dx}sinh(x)=cosh(x)[/tex]
[tex]\dfrac{d}{dx}x^n=nx^{n-1}[/tex]
[tex]\dfrac{d}{dx}C=0[/tex]
Chain rule:
[tex]\dfrac{d}{dx}[f(g(x))]=f'(g(x))g'(x)[/tex]
Where C is an arbitrary constant.
We have,
[tex]sinh(f(x))=1+x^2[/tex]
Differentiate with respect to x.
[tex]cosh(f(x))f'(x)=0+2x[/tex]
[tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex]
Therefore, the required values is [tex]f'(x)=\dfrac{2x}{cosh(f(x))}[/tex].
