Answer:
But does not touch the horizontal axis.
Step-by-step explanation:
The curve of a normal distribution extends indefinitely at the tails but does not " touch the horizontal axis."
The reason for this is that the tails of the curve suggest that a variable can take on any theoretically reasonable value, although the probability of such occurrence is considerably low.
Generally, a normal distribution curve is considered to be asymptotic to the horizontal axis.
In this exercise we have to have knowledge about distribution and complete the sentence, thus we find:
The curve of a normal distribution extends indefinitely at the tails but does not but does not touch the horizontal axis.
What is a normal distribution ?The great utility of this distribution is associated with the fact that it quite satisfactorily approximates the frequency curves of physical measurements, this curve is known as the normal or gaussine distribution.
Returning to the exercise we have to:
That when we deal with a normal distribution we will have that the tail will not touch the horizontal axis since that way it would mean that it reached zero.

Diana and Michael, who are taking different classes, are arguing about who did better on their most recent test. Diana received a score of 92 on her History test and Michael received a 688 on his Math test. The mean test score for the History class is 71 with a standard deviation of 15.The mean test score for the Math class is 493 standard deviation of 150. Who did better, relative to other students in the same class? Justify your answer.
Answer:
Diana's score is better.
Step-by-step explanation:
In Diana case :
Score = 92
Mean score , μ = 71
Standard deviation σ = 15
So,
P( x ≥ 92 ) = 1 - P( x ≤ 92 )
= 1 - P(z ≤ [tex]\frac{x - u}{\sigma}[/tex] )
= 1 - P( z ≤ [tex]\frac{92 - 71 }{15}[/tex] )
= 1 - P( z ≤ 1.4 )
= 1 - 0.9192
= 0.0808 = 8.08 %
⇒P( x ≥ 92 ) = 8.08%
∴ we get
Diana score is > 91.92% other students in the class.
In Micheal case :
Score = 688
Mean score , μ = 493
Standard deviation σ = 150
So,
P( x ≥ 688 ) = 1 - P( x ≤ 688 )
= 1 - P(z ≤ [tex]\frac{x - u}{\sigma}[/tex] )
= 1 - P( z ≤ [tex]\frac{688 - 493 }{150}[/tex] )
= 1 - P( z ≤ 1.3 )
= 1 - 0.9032
= 0.0968 = 9.68 %
⇒P( x ≥ 688 ) = 9.68%
∴ we get
Micheal score is > 90.32% other students in the class.
From both scores , we can conclude that
Diana's score is better.

What is the maximum integer value that
satisfies the inequality 5x - 11 < 43?
Answer:
If you're asking for x it's 10
Step-by-step explanation:
5x - 11 < 43
5x < 54
The maximum value of x is 10 (because 5x10<54)

Suppose has a solution. Explain why the solution is unique precisely when has only the trivial solution. Choose the correct answer.
Answer:
Because [tex]x = y[/tex], then the solution is unique.
Step-by-step explanation:
Given
[tex]Ax = b[/tex]
[tex]Ax=0[/tex]
See comment for complete question
Let there be two solutions x and y.
Such that:
[tex]Ax = b[/tex] and [tex]Ay = b[/tex]
Since:
[tex]Ax = Ay = b[/tex]
Then:
[tex]Ax - Ay = b - b[/tex]
[tex]Ax - Ay = 0[/tex]
This implies that:
[tex]Ax - Ay = A(x-y) = 0[/tex]
The only trivial solution is:
[tex]Ax - Ay = A(x-y) = 0[/tex]
Such that:
[tex]x -y = 0[/tex]
Then
[tex]x = y[/tex]
Because [tex]x = y[/tex], then the solution is unique.
Find the slope of the line represented by the data below. x|-9 -5 -1 3 7 y 4 7 10 13 16,
Select the equation that contains the point (4,7) and in which the slope equals 1
Answer:
y-7=x-4
Step-by-step explanation:
If you change the equation to y=mx+b yout would get Y=x+3 plug in the point (4,7) and you would get 7=4+3
7=7 so that is correct.
The difference of two numbers is 2. Their sum is 12. What are the numbers?
Answer:
the numbers would be 5 and 7.
Step-by-step explanation:
"the difference of two numbers is 2."
7 - 5 = 2"their sum is 12."
7 + 5 = 12since the difference of 7 and 5 is 2 and the sum of 7 and 5 is 12, 5 and 7 are the numbers that fulfill the statement.
