The correct answer is that y does not vary directly with x.

If y and x are directly related, then the equation y=kx would be true for each point in the set.

What is the explanation:

If y is directly related to x, then every point in the set would fit the equation y=kx.

For the first point, we would have 11=7k, which would imply that k=11/7.

For the second point, we would have 13=8k, which would imply that k=13/8.

By utilizing proportions to check, we can see that 11/7 does not equal 13/8.

Cross multiplying yields 11*8=7*13, or 88=91

Since this is untrue, k is not a constant and y does not change in accordance with x.

The trials in a binomial experiment are the steps. the likelihood of each trial being successful is. What is the likelihood of success? The probability of success is P=1.42.

The binomial distribution is used to summarise the number of trials or observations where each trial has the same probability of attaining a certain value.. When flipping a coin, the probability of witnessing a certain number of successful outcomes in a specified number of trials is determined by the binomial distribution; as there are only two possible outcomes, the likelihood of flipping a coin is 12 or 0.5 for each trial we do.

based on the facts provided;

here ,

n=500 ,p=0.4,q=0.6, X=number of successes

when n*p and n*q>5 then we can use normal approximations

here n*p=500*0.4=200 >5 ,n*q=500*0.6=300>5

so we can use normal approximation

mean =200

variance =200*0.6=120,

std. deviation=120^1/2

we need to find

P(185<=X<=220), applying continuity correction factor

P(184.5<=X<=220.5)

Z=(X-mean)/std. dev~N(0,1)

P((184.5–200)/10.95<=Z<=(220.5–200)/10.95)

The equation of the line parallel to the given line that contains C is obtained as y = x + 6.

For the given question;

The equation of the line is given as;

y = x + 4

The standard form of the equation of line in slope intercept form is;

y = m x + c

where, m is the slope and c is the y intercept.

On comparing;

m₁ = 1

Now, the other lien is parallel to the given line.

Thus, slopes of both lines will be equal.

m₁ = m₂ = 1

The passing points of the line are;

(x₁, y₁) = C(1, 7)

Now, the equation of lien will be;

y - y₁ = m₂(x - x₁)

Put the values;

y - 7 = 1(x - 1)

Simplifying.

y = x + 6

Thus, the equation of the line parallel to the given line that contains C is obtained as y = x + 6.

Total surface area of cylinder is 303.34 [tex]cm^{2}[/tex]

A cylinder is a 3D solid shape made up of two bases that are parallel and identical and are connected by a curved surface. These bases resemble spherical disks. The axis of the cylinder shape is a line drawn through the center or connecting the centers of two circular bases.

The surface area of a cylinder is

SA = [tex]2\pi r^{2}[/tex] + 2πrh

where:

r = radius

h = height

This formula comes from adding the areas of the surfaces of the cylinder.  It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[[tex]\frac{\pi r^{2} }{2}[/tex]]  +  ([tex]\frac{2\pi r}{2}[/tex])h  +  2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = [tex]\pi r^{2}[/tex] + πrh + 2rh

SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2×8))

SA = 3(11π + 16)

SA = 33π + 48

SA = 151.67[tex]cm^{2}[/tex]

Since we have 2 pieces, multiply this result by 2.

2(151.67[tex]cm^{2}[/tex]) = 303.34[tex]cm^{2}[/tex]

The relationship between translations, reflections, and rigid motion is that they are all types of rigid motions, which means their size does not change.

Rigid motion is the movement of a set in which the distance between points remains constant.

Translation is a type of rigid motion in which an object simply slides while maintaining its direction.

A reflection, like a mirror, causes an image to flip to another location.

We must establish a connection between translations, reflections, and rigid motion.

We can conclude from the above definitions that the size of the object remains constant, but it is undergoing different transitions.

Therefore, Translations, reflections, and rigid motion all belong to the category of transformations that are rigid motions, which means that their sizes don't change.

Length = 3 cm less than twice the width

This means that

L = 2W - 3

Where

L represents Length and W represents Width

The perimeter is given as

P = 75 cm

The perimeter is calculated as

P = 2*(L + W)

So, we have

2*(L + W) = 75

This gives

2*(2W - 3 + W) = 75

Evaluate

2*(3W - 3) = 75

Divide by 2

3W - 3 = 37.5

So, we have

3W = 40.5

Divide by 3

W = 13.5

Recall that

E. Maran sold each candy apple for $3 (Selling Price).

As per the question statement, Maran made 160 candy apples, spending $120 on ingredients and supplies while selling all the candy apples for $480.

We are required to identify the two true statements from a the set of 5 statements, provided in the question itself, related to the per candy cost price, sell price and profit of Maran.

Since he made 160 candy apples, spending $120 on ingredients and supplies, therefore, the cost price of per candy will be $(120/160) = $0.75, i.e., Statement B that Maran spent $0.75 on each candy apple is True.

Also, he sold all 160 candies for a total of $480, therefore, the sell price of each candy is $(480/160) = $3. Hence, Statement E that Maran sold each candy apple for $3., is also true.

Now, since the cost price of each candy is $0.75 and the sell price of the same is $3, then Maran made a profit of $(3 - 0.75) = $2.25 per candy. But statement D mentions that Maran earned a profit of $3 on each candy sold, which is false.

The function which has a graph with the largest positive x-intercept is C. f(x) = 2(x-8) +1

The value of the x coordinate at the point where the graph crosses the x-axis is known as the x-intercept for any curve. Alternatively, we can say that the x-intercept is the value of the x coordinate at the point where the value of the y coordinate equals zero.

Let y be 0, so lets find the x-intercept of

Answer:

x = 6 cm

Step-by-step explanation:

The two shapes are similar. That means one figure is exactly a multiple of the other figure

We can see that the ration of the length of the bigger rectangle  to the length of the smaller rectangle is 15/9 = 5/3  

Therefore the ratio of the width of the bigger rectangle  to the width of the smaller rectangle must also be 5/3

Given width of big rectangle = 10 and that of small rectangle is x

We get

10/x = 5/3

Multiply by x both sides:
x ×   10/x   =   x × 5/3

10 = 5x/3

Multiply by 3 both sides

30 = 5x

5x = 30

Dividing by 5 both sides
5x/x = 30/5
x = 6 cm

The value of the smiley face given the values of the rectangle, triangle and star is 908.

In order to solve this question, take note of the BODMAS rule. The BODMAS rule gives the order in which mathematical operations should be solved.

The value of the rectangle would be determined first using the third equation provided in the question. let a represent the value of a rectangle.

(4 x a) + (2 x a) - (3 x a) = 15

4a + 2a - 3a = 15

3a = 15

a = 15 / 3

a = 5

The next step is to determine the value of the triangle. The second equation would be used. Let b represent the value of the triangle.

(3 x 5) + (4 x b) = 47

15 + 4b = 47

4b = 47 - 15

4b = 32

b = 32 / 4

b= 8

Now, determine the value of the star using the first equation. Let the value of the star be represented with c.

5 + (3 x 8) - c = 17

5 + 24 - c = 17

29 - c = 17

c = 29 - 17

c = 12

Now, the value of the smiley face can be determined using the last equation:

12 x (8  + 12 - 5) + 8(8 . 12 - 5)
