Given,

Member of the club paying for rental bike =

10

non-member of the club paying for rental bike = 15

Also for summer season member had given $100.

Bike taken by members = x

Bike taken by non-members = y

to pay same amount,

100+10x = 15y

1. let's take x=1

110=15y

y!= integer

x can't be 1

2. let's take x=2

120 = 15y

y = 8 i.e. an integer value



So, members will take bike on rent for 2

times and non-members for 8 times.

And the amount is 120.

Point (2,10) is not satisfying the linear function y = 10x + 3 thus it will be not the solution of the system of equations.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

As per the given point (2,10)

Put it into y = x + 8

10 = 2 +  10 = 10 (satisfy)

Put it into y = 10x + 3

10 = 10 x 2 + 3 = 23 ≠ 10 (Not satisfy)

The degree of agreement among observers can be established by using a statistical measure of Inter rater reliability (Option c is correct)

Interrater reliability describes how closely two or more people agree.

Because everyone has used it, interrater reliability is the easiest type of reliability to comprehend. For instance, watching a judged event like dog shows or Olympic ice skating depends on human observers upholding a high level of consistency across observers.

Higher values of Kendall's coefficient, which ranges from 0 to 1, suggest more inter-rater reliability. Excellent values are greater than 0.9, and a value of 1 denotes perfect agreement. For the purpose of testing hypotheses, statistical software can compute confidence ranges and p-values.

The primary purpose of the passage is to caution against uncritical embrace of nuclear fusion power as a major energy source.

Nuclear fission generates a significant amount of radioactive waste, which can be hazardous and needs to be stored securely for a long period of time. Nuclear fusion waste has a lower radioactivity and decays significantly more quickly. Fossil fuels like gas and oil are not required for nuclear fusion.

Radiation that is released voluntarily is referred to as radioactivity. An atomic nucleus that is unstable for some reason accomplishes this by "wanting" to give up some energy in order to change its configuration to one that is more stable.

The passage begins by classifying as misconceptions favorable views about nuclear fusion power and finishes by recommending the use of current energy sources going forward rather than nuclear fusion power. All of this adds up to the text trying to warn against uncritically embracing nuclear fusion power as a major source of energy.

A regression equation is used in stats to find out what relationship, if any, exists between sets of data.

The lateral surface area of the walls of the warehouse is 18,000 sq ft.

Area is a measure of the size of a surface or the amount of space that a two-dimensional shape occupies. It is typically measured in square units, such as square feet or square meters. The area of a shape is calculated by multiplying the length and width of the shape together.

To find the lateral surface area of the walls of the warehouse, you need to find the combined area of all the exterior walls. To do this, you can use the formula for lateral surface area, which is:

Lateral Surface Area = 2 * (l * h + w * h)

where l is the length of the wall, w is the width of the wall, and h is the height of the wall.

Using this formula, we can find the lateral surface area of each wall and add them together to get the total lateral surface area:

Wall 1: Lateral Surface Area = 2 * (100 ft * 30 ft) = 6,000 sq ft

Wall 2: Lateral Surface Area = 2 * (200 ft * 30 ft) = 12,000 sq ft

Total Lateral Surface Area = 6,000 sq ft + 12,000 sq ft = 18,000 sq ft

Any equation with a variable difference in it is a difference equation. The following variables affect how different equations are categorized. • The equation's order. The highest order of difference in the equation is represented by the order.

y = Mt (x - 1) + 0

Where Mt = 1/3* 1(0-2)²

Mt = 1/3*4

Mt = 4/3

From equation 1

y = (4/3)(x - 1)

Function at x = 0.7

f(0.7) = 4/3(0.7 -1 )

= 4/3(-0.3)

F(0.7) = -2/5

Let, u = y - 2

Answer:  5 4/15

Step-by-step explanation:

1 3/5 + 3 2/3 = 8/5 + 11/3

Find the common denominator (5 and 3) = 15

So 8/5 equals to 24/15 because if 5 x 3 = 15 , 8 must also multiply by 3.

11/3 equals to 55/15 because if 3 x 5 = 15 , 11 must also multiply by 5.

Thus 24/15 + 55/15 = 79/15

This is an improper fraction, so converting to mixed number:

79/15 = 5 4/15 because 5 x 15 + 4 = 79

Answer:

1 - (5/6)x = 2y

Step-by-step explanation:

To write the equation y = 5/12x - 1/2 in standard form, we need to first get rid of the fractions by multiplying both sides of the equation by the least common denominator of the fractions, which in this case is 12. This gives us the equation 12y = 5x - 6. Next, we can rearrange the terms on the right-hand side of the equation to get 6 - 5x = 12y. Finally, we can divide both sides of the equation by 6 to get the equation in standard form, which is 1 - (5/6)x = 2y. The standard form of the equation is thus 1 - (5/6)x = 2y.

Answer:

5/12x = y - 6

Step-by-step explanation:

To write the equation y = 5/12x - 1/2 in standard form, we need to first move all the terms that contain x to one side of the equation and all the constants to the other side. This will give us the equation 5/12x - y = -1/2. Next, we need to multiply both sides of the equation by the denominator of the fraction on the right-hand side to eliminate the fraction. This gives us 5/12x - y = -6. Finally, we need to add y to both sides of the equation to obtain the standard form of the equation, which is 5/12x = -6 + y. This can be written more concisely as 5/12x = y - 6. Therefore, the equation y = 5/12x - 1/2 can be written in standard form as 5/12x = y - 6.

The probability of not selecting any of the correct six integers in a lottery is 0.18. This is calculated by subtracting the probability of selecting all the correct integers from 1, and the probability of selecting all the correct integers is the product of the probabilities of selecting each of the integers.

The probability of selecting none of the correct six integers in a lottery, where the order in which these integers are selected does not matter, from the positive integers not exceeding the given integers is 0.18. To calculate this probability, we must first find the probability of selecting all the correct integers. This is done by calculating the probability of selecting each of the integers individually and multiplying them together. For example, the probability of selecting 6 is 1/5, since there are five positive integers not exceeding 6. The probability of selecting 8 is 2/5, since there are five positive integers not exceeding 8 and two of them are 8. The probability of selecting 9 is 3/5, since there are five positive integers not exceeding 9 and three of them are 9. The probability of selecting 10 is 4/5, since there are five  not exceeding 10 and four of them are 10. The probability of selecting 11 is 5/5, since there are five positive integers not exceeding 11 and five of them are 11

Probability of selecting all the correct integer

= (1/5)*(2/5)*(3/5)*(4/5)*(5/5)

The amount of the last payment that Elroy will make is $710, which includes the $200 monthly payment and a balance of $510.

The last payment amount is the result of the mathematical operations of subtraction and multiplication.

The first mathematical operation was the subtraction of the down payment from the total cost of the video game system.

Using multiplication, the monthly payments are determined to be $3,400 for 17 months.  This is subtracted from the remaining balance to obtain the last payment amount.

The cost of a custom video game/virtual sound system = $4,210

Down payment = $100

The remaining balance for monthly payment = $4,110 ($4,210 - $100)

Payment period = 18 months (1¹/₂ years)

Monthly payments = $200

Payment for the first 17 months = $3,400 (17 x 200)

Last payment = $710 ($4,110 - $3,400)

Thus, if Elroy makes the minimum monthly payment of $200 till the last payment, then he will pay $710 to settle the account.
