Which relation is a function
Answer:
A function is a relation in which each input has only one output.
Step-by-step explanation:
In the relation Y is a function of X because for each input x(1,2,3 or 0) there is only one output y.
The relation that is a function is the relation (d)
Checking the relations that are functionsFrom the question, we have the following parameters that can be used in our computation:
The relations (1) to (4) represent the given parameter (see attachment)
Next, we test the options
Relation (a)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (b)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (c)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (d)
This relation is a function
This is because the inputs all point to different output values
Hence, the option (d) is a relation

How do you do these two questions?
Step-by-step explanation:
(a) ∫₋ₒₒ°° f(x) dx
We can split this into three integrals:
= ∫₋ₒₒ⁻¹ f(x) dx + ∫₋₁¹ f(x) dx + ∫₁°° f(x) dx
Since the function is even (symmetrical about the y-axis), we can further simplify this as:
= ∫₋₁¹ f(x) dx + 2 ∫₁°° f(x) dx
The first integral is finite, so it converges.
For the second integral, we can use comparison test.
g(x) = e^(-½ x) is greater than f(x) = e^(-½ x²) for all x greater than 1.
We can show that g(x) converges:
∫₁°° e^(-½ x) dx = -2 e^(-½ x) |₁°° = -2 e^(-∞) − -2 e^(-½) = 0 + 2e^(-½).
Therefore, the smaller function f(x) also converges.
(b) The width of the intervals is:
Δx = (3 − -3) / 6 = 1
Evaluating the function at the beginning and end of each interval:
f(-3) = e^(-9/2)
f(-2) = e^(-2)
f(-1) = e^(-1/2)
f(0) = 1
f(1) = e^(-1/2)
f(2) = e^(-2)
f(3) = e^(-9/2)
Apply Simpson's rule:
S = Δx/3 [f(-3) + 4f(-2) + 2f(-1) + 4f(0) + 2f(1) + 4f(2) + f(3)]
S ≈ 2.5103

The dotplot shows the heights of 25 students in Mrs. Navard’s statistics class.
A) Find the Percentile for Lynette, the student who is 65 in. tall.
B) Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher?
Answer:
A)Percentile for Lynette, the student who is 65 in. tall is 36th
B) Asher is 22 inches tall.
Step-by-step explanation:
Percentile : It is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls
A) Find the Percentile for Lynette, the student who is 65 in. tall.
No. of students below 65 inch =9
So, Percentage of data below 65 inch =[tex]\frac{9}{25} \times 100 = 36 \%[/tex]
So, Percentile for Lynette, the student who is 65 in. tall is 36th
B)Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher
[tex]88=\frac{x}{25} \times 100 \\\frac{2200}{100}=x[/tex]
22=x
So, No. of students below or st 88th percentile = 22
So, Asher is 22 inches tall.

Suppose heights of seasonal pine saplings have an unknown distribution with mean 291 and standard deviation 14 millimeters. A sample of size n=55 is randomly taken from the population and the mean is taken. Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
Answer:
1.89
Step-by-step explanation:
The center al limit theorem for means states that the standard deviation of the normal distribution of sample means is equal to the original distribution’s standard deviation divided by the square root of the sample size. the original standard deviation is 14 and the sample size is 55.
It was found that the mean length of 100 diodes (LED) produced by a company
was 20.05 mm with a standard deviation of 0.02mm. Find the probability that a diode
selected at random would have a length less than 20.01mm
Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that a diode selected at random would have a length less than 20.01mm.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, we have that:
The mean is of [tex]\mu = 20.05[/tex].The standard deviation is of [tex]\sigma = 0.02[/tex].The probability that a diode selected at random would have a length less than 20.01mm is the p-value of Z when X = 20.01, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{20.01 - 20.05}{0.02}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% probability that a diode selected at random would have a length less than 20.01mm.

A regular Pyramid is formed from 3 right triangles as shown below use the information given in the figure to find the length of RT.
Answer:
The length of BD is 65 units.
Step-by-step explanation:
ΔADC is a right angle triangle, we will use the Pythagorus Theorem to find the length CD.
Formula of the Pythagorus Theorem :
⇒ a² + b² = c²
⇒ AD² + CD² = AC²
The value of AD is 54 and the value of AC is 90:
54² + CD² = 90²
Solve for CD:
54² + CD² = 90²
CD² = 90² - 54²
CD² = 5184
CD = √5184
CD = 72
ΔADC is also a right angle triangle, we will use the Pythagorus Theorem to find the length BD.
Formula of the Pythagorus Theorem :
⇒ a² + b² = c²
⇒ BD² + CD² = BC²
The value of CD is 72 and the value of BC is 97:
BD² + 72² = 97²
Solve for BD:
BD² = 97² - 72²
BD² = 4225
BD = √4225
BD = 65

Devaughn is 14 years older than Sydney. The sum of their ages is 110. What is Sydney's age?
Answer:
The answer would be 48
Sydney is 48
Devaughn is 62
48 + 62 = 110
Okays so you start by doing the equation 110 - 14 = 96
then dividing 96 by 2 (96 ÷ 2) which is 48
add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^

6x - 10y = 20 in slope intercept form
The general equation of a straight line in slope-intercept form is given as:
y = mx + c
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.
What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
6x - 10y = 20 _____(1)
The slope intercept form is y= mx + c
So,
Subtract -6x on both sides.
6x - 10y - 6x = 20 - 6x
-10y = 20 - 6x
Divide both sides by -10.
y = 20/-10 + 6x/10
y = -2 + 3x/5
y = (3/5)x - 2
Thus,
The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.
