The number of reserved seats and the number of general seats, if The cost for general admission = $3.50, The cost for a reserved seat = $7, is 382 and 622 respectively.

The equals sign is used in equations to indicate the equality of two expressions in a formula. Equation: A statement that two variable or integer expressions are equal.

Given:

The cost for general admission = $3.50,

The cost for a reserved seat = $7,

The total cost = $4851.00

The total seat = 1004

Write the equation as shown below,

x + y = 1004  (Here, y is the number of a reserved seat and x is the number of a general seat)

3.5x + 7y = 4851

Solve the equations by using the elimination method,

y = 382, x = 1004 - 382 = 622

Answer:

x = 3.7

Step-by-step explanation:

By applying sine ratio for the given angle B,

sin(39°) = \(\frac{\text{Opposite side}}{\text{Hypotenuse}}\)

sin(39°) = \(\frac{AD}{AB}\)

0.6293 = \(\frac{AD}{7}\)

AD = 4.41

By applying tangent ratio for the given angle C,

tan(50°) = \(\frac{\text{Opposite side}}{\text{Adjacent side}}\)

1.19 = \(\frac{AD}{x}\)

1.19 = \(\frac{4.41}{x}\)

The probability statements after continuity correction are given as follows:

Continuity correction is used as a "correction" when a continuous distribution is used to approximate a discrete distribution. One example of this is the approximation of the binomial distribution to the normal distribution.

Hence, using continuity correction, the range of values that corresponds to a number of exactly x is given as follows:

x - 0.5 < x < x + 0.5.

Thus the range of values of 118 is given as follows:

117.5 < x < 118.5.

Answer:

prime factorization of 225 = 32•52.

Step-by-step explanation:

The number 225 is a composite number so, it is possible to factorize it. 225 can be divided by 1, by itself and at least by 3 and 5.

A composite number is a positive integer that has at least one positive divisor other than one or the number itself. In other words, a composite number is any integer greater than one that is not a prime number.

Answer:

The value of x is 66.

Step-by-step explanation:

The median of a data set is the term that separates the lower half of the set from the upper half.

In a set with even cardinality, the median is given by the mean of it's two middle terms.

In this question:

Cardinality: 8

Middle terms: 4th and 5th, which are x - 5 and x + 1.

The median is 64.

This means that:

\(\frac{x - 5 + x + 1}{2} = 64\)

\(2x - 4 = 128\)

\(2x = 132\)

\(x = \frac{132}{2}\)

\(x = 66\)

The value of x is 66.

Answer:

x = 3 , y = 1

Step-by-step explanation:

2x + y = 7

3x + y = 8

solution

2x + y = 7-----------(1)

3x - y = 8------------(2)

from equation 1

2x + y = 7

y = 7 - 2x-------------(3)

substitute equation 3 into equation 2

3x - y = 8

3x - (7 - 2x) = 8

3x - 7 + 2x = 8

3x + 2x = 8 + 7

5x = 15

divide through by the coefficient of x

5x/5 = 15/5

x = 3

to find y

substitute x into equation 1

2x + y = 7

2(3) + y = 7

6 + y = 7

y = 7 - 6

y = 1

At least 75% of the data might very well fall between $3.25 and $3.81. According to Chebyshev's theorem, at least 75% of the value systems in a distribution are well within 2 the mean standard deviation.

A delivery has at least 89% of its values inside of three of the mean's standard deviation.

We have the following in this problem:

Mean = $3.53

$0.14 is the standard deviation.

Using Chebyshev's Theorem, determine the range that contains least 75% of the information will live.

2 standard deviations from the mean.

So 3.53 - 2*0.14 = $3.25 becomes 3.53 + 2*0.14 = $3.81.

At least 75% of the data might very well fall between $3.25 and $3.81.

Answer:

Step-by-step explanation:

your welcome :)

Answer:

I believe that the answer is 6  

Step-by-step explanation:

Because I got it right

The denominator of the function, n(x), is the place where vertical asymptotes can be located. If the numerator, t(x), is not zero for the same value of x, then the vertical asymptotes can be determined by solving the equation n(x) = 0 where n(x) is the denominator.

Despite not being a part of the function graph, a vertical asymptote is a vertical line that serves as a guide.

It happens at an x-value that is outside the function's domain, therefore the graph can never cross it.
