A school show had sold the ticket sales of first and second nights. The price of a student ticket is $3.54, a So, the correct answer is option (d).

Total sale on tickets at the first night = $1345

Total sale on tickets at the second night = $935

Let the price of student ticket and adult ticket in school show be "$x" and "$y" respectively. According to problem,

On first night total sale,

180x + 110y = $1345 --(1)

On Second night total sale,

100x + 90y = $935 --(2)

we have to determine the price of student ticket i.e x and price of adult ticket i.e y .. We have a system of linear equation which consists two equations (1) and (2) . Now, we solve these equations using Substitution method,

From equation (2), 100x = 935 - 90y

=> x = (935 - 90y )/100 --(*)

Substitute the value of x in equation (1) 180x + 110y = $1345

=> 180(935 - 90y )/100 + 110y = 1345

Simplify ..

=> 168120 - 16200y + 11000y = 134500

=> 168120 - 134500 = 16200y - 11000y

=> 33620 = 5200y

=> y = 33620/5200

=> y = 6.46

put the value of y in equation (*) we get,

x = (935 - 90× 6.46)/100 = 3.536

Hence, the value of x is $3.536 and value of y is $6.46..

Step-by-step explanation:

y-y1=m(x-x1)

Answer:

C

Step-by-step explanation:

[tex]\frac{5}{2}[/tex] x = y → (1)

2x + [tex]\frac{4}{5}[/tex] y = 8 → (2)

substitute y = [tex]\frac{5}{2}[/tex] x into (2)

2x + [tex]\frac{4}{5}[/tex] ([tex]\frac{5}{2}[/tex] ) = 8

2x + 2 = 8 ( subtract 2 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

substitute x = 3 into (1)

y = [tex]\frac{5}{2}[/tex] × 3 = [tex]\frac{15}{2}[/tex]

Derivatives is used to calculate the maximum value of a function.

We will set the first derivative of the function to zero and solve for x to get the critical point. If we take the second derivative or f''(x), then we can find out whether this point will be a maximum or minimum. If the second derivative is positive, it will be a minimum value.

Answer: 1/10th

Step-by-step explanation:

20 different lengths, 2 are 21.5 = 2/20 reduce to 1/10 so 10%

The least amount of interest, if Pedro has a balance of $5810 on a credit card with an APR of 16.2%, is $78.345 for one month, so option A is correct.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Pedro has a balance of $5810 on a credit card with an APR of 16.2%,

Calculate the simple interest for one month as shown below,

[tex]SI = P \times r \times t / 100[/tex]

SI = 5810 × 16. 2 × 1 / (12 ×100)   [time in year = 1 / 12]

SI = $78.345

SI =  5810 × 16. 2 × 2 / (12 ×100)   [For 2 months]

SI = $156.87

Therefore, the least amount of interest, if Pedro has a balance of $5810 on a credit card with an APR of 16.2%, is $78.345 for one month.

The earth is 21.24 x 10¹⁴ miles far from the star.

What are the light years?

A light-year is a significant length measure that is used to express astronomical distances. It is around 9.46 trillion kilometers, or 5.88 trillion miles, in length.

We have given,

1 light year = 5.9 x 10¹² miles

Distance of the star =  3.6 x 10² light years

To get this we just convert the distance of the star in light years into miles.

3.6 x 10² light years x( 5.9 x 10¹² miles/1 light years)

We cancel out the lightyears and then we are left with:

3.6 x 10² light years x 5.9 x 10¹² miles

In dealing with scientific notation, when we multiply them we can treat the coefficients and exponents of 10 separately.

Coefficients:

3.6 x 5.9 = 21.24

Exponents of 10:

10² x 10¹² = 10⁽²⁺¹²⁾ = 10¹⁴

The binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a series of n independent experiments. Each asks a yes-no question and each has its own Boolean outcome: success (probability p) or failure (probability p) (probability q = 1-p.  A single success/failure experiment is also called a Bernoulli trial or Bernoulli experiment, and a series of results is called a Bernoulli process. For one trial, n = 1, binomial distribution is Bernoulli distribution. The binomial distribution is the basis for the common binomial test of statistical significance.

In general, (A + B)⁵ = A⁵ + 5A⁴ᵇ + 10A²ᵇ*³ + 10A³ᵇ*² + 5AB⁴ + B⁵

Answer:

Step-by-step explanation:

Answer:

The relationship shown in the table is not proportional. A proportional relationship is one in which the ratio of two quantities is always constant. In the table, we can see that the ratio of the values in the y column to the corresponding values in the x column is not constant. For example, the first two values in the y column are -27 and 12, which have a ratio of -27/1 and 12/2, respectively. These ratios are not equal, which indicates that the relationship is not proportional.

Furthermore, if the relationship were proportional, we would expect the values in the y column to increase at a consistent rate as the values in the x column increase. However, this is not the case in the table. For example, the first two values in the x column are 1 and 2, and the corresponding values in the y column are -27 and 12. The difference between these values is -27 - 12 = -39, which is a large negative value. However, the difference between the next two values in the y column is 57 - 147 = -90, which is a much larger negative value. This indicates that the relationship is not proportional, because the differences between the y values do not increase at a consistent rate as the x values increase.
