Answer:

x = 35

y = 21

x - y = 14

Step-by-step explanation:

x/y = 5/3 => x = 5y/3

x + y = 56 => 5y/3 + y = 56 => 8y/3 = 56 => y/3 = 7 => y = 21 => x = 56 - 21 = 35 => x- y = 35 - 21 = 14

Answer: The value of x-y is 14.

Step-by-step explanation:

If  x:y=5:3   is equal to x+y=56  then you can say that 5/8 of 56 is equal to the value of x  and 3/8 of 56 is equal to the value of y.  

so x= [tex]\frac{5}{8}*56[/tex]  

    x = 0.625 * 56

  x = 35  

And   y=   3/8 *56

     y= 0.375 *56

    y= 21      

Check: 35 + 21 =56

Now we know the value of x is 35 and the value of x is 21.

so x- y has to be 35 -21 = 14

Answer:

Step-by-step explanation:

Let x be the random variable representing the height of the students. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 68.5

σ = 2.7

the probability that a student's height is between 67.5 and 71.0 inches exclusive is expressed as

P(67.5 < x < 71.0)

For x > 67.5,

z = (67.5 - 68.5)/2.7 = - 0.37

Looking at the normal distribution table, the probability corresponding to the z score is 0.36

For x < 71.0

z = (71.0 - 68.5)/2.7 = 0.93

Looking at the normal distribution table, the probability corresponding to the z score is 0.82

Therefore,

P(67.5 < x < 71.0) = 0.82 - 0.36 = 0.46

The number of students whose height is between 67.5 and 71.0 inches is

0.46 × 1000 = 460 students

The probability that a student's height is greater than or equal to 74.0 inches is expressed as P(x ≥ 74)

P(x ≥ 74) = 1 - P(x < 74)

For x < 74,

z = (74 - 68.5)/2.7 = 2.04

Looking at the normal distribution table, the probability corresponding to the z score is 0.98

P(x ≥ 74) = 1 - 0.98 = 0.02

The number of students whose height are greater than or equal to 74.0 inches is

0.02 × 1000 = 20 students

What are factors of production?

" Factors of production are resources that are the building blocks of the economy; they are what people use to produce goods and services. Economists divide the factors of production into four categories: land, labor, capital, and entrepreneurship."

What are some examples of entrepreneurship as a factor of production?

An entrepreneur is a person who combines the other factors of production - land, labor, and capital - to earn a profit. The most successful entrepreneurs are innovators who find new ways to produce goods and services or who develop new goods and services to bring to market. Without the entrepreneur combining land, labor, and capital in new ways, many of the innovations we see around us would not exist. Entrepreneurs are a vital engine of economic growth helping to build some of the largest firms in the world as well as some of the small businesses in your neighborhood. Entrepreneurs thrive in economies where they have the freedom to start businesses and buy resources freely.

So, option (A) is correct

Answer:

y = 1/4x +2

Step-by-step explanation:

y -4 = 1/4 (x -8)

This is point slope form

Distribute

y-4 = 1/4x -2

Add 4 to each side

y-4+4 = 1/4x -2+4

y = 1/4x +2

This is slope intercept form ( y= mx+b) where m is the slope and b is the y intercept

Answer:

A

Step-by-step explanation:

The base angles L and N are congruent.

Thus the triangle is isosceles and ML = MN, that is

3x = x + 8 ( subtract x from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Thus

MN = x + 8 = 4 + 8 = 12 → A

Answer:

C no, because one x value corresponds to two different y values

Step-by-step explanation:

The x value of 3 goes to two different y values

This means this cannot be a function

This is not a one to one correspondence

Answer: C

Step-by-step explanation: In order for a table to represent a function each x-value needs to correspond to exactly 1 y-value.

Notice that in the table, the 3 appears twice and it corresponds to a 5 in one case and it corresponds to a 6 in another case.

Since the x-value of 3 corresponds to more than 1 y-value,

no, this table does not represent a function.

Answer:

nth term = 2n^2 - 3n - 6.

Step-by-step explanation:

                      n   =  1   2    3    4     5     6    7  

                             - 7   -4   3   14   29   48   71  

Differences                3    7   11    15   19    23

Differences                   4   4     4    4     4

So the first term in the Rule is 2n^2

Subtracting  the values of 2n^2 from the original terms:

                  - 7   -4   3      14   29   48   71  

2n^2           2     8  18    32   50   72   98

Subtrct       -9   -12 -15  -18   -21   -24   -27

                       -3     -3    -3   -3    -3     -3

So we have -3n  and the last  term is  -6 because    -7 = 2(1)^2 -3 - 6  and the other terms fit this pattern as well.

The nth term rule of the provided quadratic sequence to find the n'th term of the sequence is 2n²-3n-6.

The quadratic sequence is the series of the numbers in which the rule for the n'th term included an n squared term (n²). The quadratic equation for n can be given as,

[tex]an^2+bn+c[/tex]

Here, (2a) is equal to the second difference, (3a+b) is equal to the first difference and (a+b+c) is equal to the first term.

The sequence given in the problem is

[tex]-7, -4, 3, 14, 29, 48, 71[/tex]

Thus, (a+b+c) is,

[tex]a+b+c=-7[/tex]                ......1

The first difference between the sequence is,

[tex]3,7,11,15,19,23[/tex]

Thus, the value of (3a+b) is,

[tex]3a+b=3\\b=3-3a[/tex]                      ......2

The second difference between the sequence is,

[tex]4,4,4,4,4[/tex]

Thus, the value of 2a is,

[tex]2a=4\\a=\dfrac{4}{2}=2[/tex]

Put this value in equation 2 as,

[tex]b=3-3\times2\\b=-3[/tex]

Put the value of a and b in equation 1 as,

[tex]2-3+c=-7\\c=-7+1\\c=-6[/tex]

Put these values in the above formula as,

[tex]2n^2-3n-6[/tex]

Answer : The expression which is equivalent to [tex]\sqrt[4]{9}^{\frac{1}{2}x}[/tex] is [tex]9^{(\frac{1}{8}x)}[/tex].

Step-by-step explanation :

The given expression is:

[tex]\sqrt[4]{9}^{\frac{1}{2}x}[/tex]

As we know that:

[tex]\sqrt[4]{x} =x^{\frac{1}{4}}[/tex]

So, by solving the above expression, we get:

[tex]\Rightarrow 9^{(\frac{1}{4}\times \frac{1}{2}x)}[/tex]

By multiplying the power of 9, we get the following expression.

[tex]\Rightarrow 9^{(\frac{1}{8}x)}[/tex]

Hence, the expression which is equivalent to [tex]\sqrt[4]{9}^{\frac{1}{2}x}[/tex] is [tex]9^{(\frac{1}{8}x)}[/tex].

Answer:

tan(C) = 3/4

Step-by-step explanation:

If the sine of angle C is 3/5 and we want to find the tangent of the angle C, we can first find the cosine of angle C using the following equation:

[tex]sin^2(C) + cos^2(C) = 1[/tex]

[tex](3/5)^2 + cos^2(C) = 1[/tex]

[tex]cos^2(C) = 1 - 9/25[/tex]

[tex]cos^2(C) = 16/25[/tex]

[tex]cos(C) = 4/5[/tex]

Then, we can find the tangent relation using the equation:

[tex]tan(C) = sin(C) / cos(C)[/tex]

[tex]tan(C) = (3/5) / (4/5)[/tex]

[tex]tan(C) = 3/4[/tex]

Answer:

=1344 pi units^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

V = 1/3 pi * (8)^2 * 63

V =1344 pi units^3

The volume of the cone is found to be 1344[tex]\pi[/tex] cubic units.

A cone is geometric structure of 3-Dimensions with a smooth transition from a flat, usually circular base to the peak of a point that creates an axis to the base's centre.

The radius of the cone = 8 units.

The height of the cone = 63 units.

Apply the formula of the cone and substitute the values

volume = [tex]\frac{1}{3}[/tex][tex]\pi 8^{2}[/tex]×[tex]63[/tex]

= [tex]1344\pi[/tex] cubic units

Therefore, the volume of the cone is found to be [tex]1344\pi[/tex] cubic units.
