The best description of the shape of the sampling distribution is C. Approximately normal.

The sampling distribution of the sample proportion of those who will be cured with the skin cream is approximately normal.

A sampling distribution is the distribution of a statistic calculated from a random sample of data. In this case, the statistic is the sample proportion of those who will be cured with the skin cream.

The Central Limit Theorem states that the sampling distribution of a statistic will be approximately normal if the sample size is large enough, regardless of the shape of the underlying distribution.

Since the sample size of 100 people is large enough, the sampling distribution of the sample proportion of those who will be cured with the skin cream is approximately normal.

Answer:

Step-by-step explanation:

Given the points

   (4, 2)

   (3, 5)

We know that the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept

substituting m=-3 and the point (4, 2) to get the y-intercept i.e. b

2=(-3)4 + b

2 = -12 + b

b = 2+12

b = 14

Now, substituting b=14 and m=-3 in the slope-intercept form to determine the equation of a line in the slope-intercept.

y=(-3)x+(14)

y=-3x+14

Thus, the equation of the line containing (4,2) and (3,5)  in the slope-intercept form will be:

The ordered pairs of the solution to the system of equation are (-5, -3).

System of equation can be solved using methods like substitution method, elimination method and graphical method.

Let's solve the system of equation by substitution method.

Therefore,

x - 3y = 4

Hence,

x = 3y + 4

Substitute the value of x in equation(i)

-3x + 2y = 9

-3(3y + 4) + 2y = 9

-9y - 12 + 2y = 9

-7y = 9 + 12

-7y = 21

y = 21 / -7

y = -3

The efficiency for a steel specimen immersed in a phosphating tank is the weight of the phosphate.

a) The equation of the estimated regression line is ŷ = - 16.592 + 0.1017x.

b) A point estimate is 1.9174 for true average efficiency ratio when tank temperature is 182.

c) The values of the residuals from the least squares line for the four observations for which temperature is 182 are -1.0774, -0.1874, 0.1226, 0.7826..

We have given the accompanying data on tank temperature (x) and efficiency ratio (y).

a) We have to find out the equation of the estimated regression line. Consider the calculations shown in the above table:

ΣΧ= 4308 ; ΣΥ= 39.99 ; ΣΧΥ = 7229.47 ;

ΣX² = 773790

Determine the slope and intercepts using the following formulas,

Slope b₁ = (n ΣΧΥ - ΣX ΣΥ)/(nΣΧ² - (ΣX)²)

=> b₁ = [24 (7229.47) - (4308) (39.99)]/(24(773790)-(4308)²)

=> b₁ = 1230.36/12096 = 0.10171626984

=> b₁ ≈ 0.1017

Intercept, b₀ = ΣY /n - b₁ΣΧ /n

=> b₀ = 39.99/24 - 0.1017×4308/24

= -16.592

Thus, the estimated regression equation of the form, ŷ = b₀ + b₁ x

ŷ = - 16.592 + 0.1017x

b) Calculate the point estimate for true average efficiency ratio when tank temperature is 182.

y = -16.592 + 0.1017x

=> y= -16.592 +0.1017 (182)

=> y= 1.9174

Therefore, the point estimate for true average efficiency ratio when tank temperature is 182 is 1.9174..

c)We have to find out the values of the residuals from the least squares line for the four observations for which temperature is 182.

From part (b), the value of ŷ is 1.9174.

The table below shows the residuals.

Vi ŷ e = y₁ - y

0.84 1.9174 -1.0774

1.73 1.9174 -0.1874

2.04 1.9174 0.1226

Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.

Here,

In order to move from A = (-3,3) to A' = (-6, 5), we must first move 3 units to the left and 2 units up.

Step 1's change causes x to become x-3.

The set {x | x < 0 or x > 3 } consists of all real numbers that are either less than 0 or greater than 3. This set can be represented as the union of the set of all numbers less than 0, which can be written as (-∞, 0), and the set of all numbers greater than 3, which can be written as (3, ∞).

E)  f(x) → ∞ as x → -2⁻ and as x → 2⁺, f(x) → -∞ as x → -2⁺ and as x → 2⁻

Step-by-step explanation:

Given function:

[tex]f(x)=\dfrac{3x^2}{x^2-4}[/tex]

The domain of a function is the set of all possible input values (x-values).

A rational function is undefined when the denominator is equal to zero.

The denominator of the given function is zero when:

[tex]\implies x^2-4=0[/tex]

[tex]\implies x^2=4[/tex]

[tex]\implies \sqrt{x^2}=\sqrt{4}[/tex]

[tex]\implies x= \pm 2[/tex]

Therefore the domain of the function is:

The excluded x-values are x = -2 and x = 2.

To find the behaviour of the function near the excluded x-values, input values of x that are very near either side of excluded values:

[tex]x \rightarrow -2^-: \quad f(-2.001)=\dfrac{3(-2.001)^2}{(-2.001)^2-4}=3002.250...[/tex]

[tex]x \rightarrow -2^+: \quad f(-1.999)=\dfrac{3(-1.999)^2}{(-1.999)^2-4}=-2997,750...[/tex]

[tex]x \rightarrow 2^-: \quad f(1.999)=\dfrac{3(1.999)^2}{(1.999)^2-4}=-2997.750...[/tex]

[tex]x \rightarrow -2^+: \quad f(2.001)=\dfrac{3(2.001)^2}{(2.001)^2-4}=3002.250...[/tex]

Therefore, the behaviour of the function near the excluded x-values:

The number of sheep originally on the farm will be equal to 200.

The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from.

Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.

As per the given information in the question,

Let the number of animals originally at the farm is x.

60% of the animals are cows.

So, 0.6x are cows.

If there are 60% cows, then there are 40% of sheep.

So, 0.4x are sheep.

The quantity of sheep multiplies when many cows and sheep were introduced to the property.

As a result, the farm now has the same amount of sheep that it did before.

Number of sheep added = 0.4x

There are total 260 animals added to the farm.

So,

Number of sheep added = 260-0.4x

Total number of animals = x + 260

The percentage of cows increased to 20%.

Initial number of cows at farm + cows added = Initial number of cows at farm + 20% of the total cows initially at the farm.

0.6x + (260-0.4x) = 0.6x + 0.2(0.6x)

0.6x+260-0.4x = 0.6x+0.12x

0.2x+260 = 0.6x+0.12x

0.2x+260 = 0.72x

260 = 0.52x

x = 260/0.52

x = 500

Thus, the farm's initial animal population was 500.

0.6x = the amount of cows that were first on the farm= 0.6(500) = 300 cows

0.4x = the amount of sheep that were initially on the farm = 0.4(500) = 200 sheep

0.4x = Sheep added = 200

the orthogonal projection of [-2 2] onto the line through [-1 5] and the origin is [-1.25 3.75] using unit vector.

First, we need to calculate the unit vector of the line. This can be done by subtracting the two given points and dividing the result by the magnitude of the vector:

[-1 5] - [0 0]

= [-1 5]

|[-1 5]| = sqrt(1^2 + 5^2) = sqrt(26) = 5.1

Unit vector = [-1/5.1 5/5.1] = [-0.196 0.980]

Next, we need to calculate the dot product of the vector [-2 2] and the unit vector [-0.196 0.980]. This will give us the scalar projection.

(-2)(-0.196) + (2)(0.980) = -0.392 + 1.960 = 1.568

Finally, we can calculate the orthogonal projection by multiplying the scalar projection by the unit vector.

[-0.196 0.980] (1.568) = [-0.301 1.527]

Rounding to two decimal places, the orthogonal projection of [-2 2] onto the line through [-1 5] and the origin is [-1.25 3.75].

Simple Interest = (Principal × Rate × Time) / 100

Given that loan Amy is 89000 monthly payment is 479.66 rate is 4.2

b) M = -1

P = 1

R = 1.6

c) M = -125

P = 125

N = -50

d) N = -6

P = 15

R = 24

a) We are given that P = 2¹/₂

From the point 0 of the number line to point P is 5 units and as such;

Each unit = 2¹/₂/5 = ¹/₂

Thus;

M = -2¹/₂

N = -1

R = 4

b) We are given that N = -0.4

From the point 0 of the number line to point N is 2 units and as such;

Each unit = 0.4/2 = 0.2

Thus;

M = -1

P = 1

R = 1.6

C) We are given that R = 200

From the point 0 of the number line to point R is 8 units and as such;

Each unit = 200/8 = 25

Thus;

M = -125

P = 125

N = -50

D) We are given that M = -15

From the point 0 of the number line to point N is 5 units and as such;

Each unit = 15/5 = 3

Thus;

N = -6

P = 15

R = 24
