Answer:

\(17/2\)

Step-by-step explanation:

I don't know what the column method is, but I can give you another method of solving.

We know that \(1.5=1~1/2=3/2\), so we really want to find \(10-3/2\).

We know that \(20\) divided by \(2\) is \(10\), so we really want to find \(20/2-3/2\).

We can combine fractions with like denominators, so we really want to find \((20-3)/2\).

We know that \(20-3\) is \(17\), so we really want \(17/2\). We can't simplify \(17/2\) anymore.

So, the answer is \(\boxed{17/2}\) and we're done!

Answer:

3/4

Step-by-step explanation:

The value of cos C x sin A is 3/2.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

AB = 1

AC = 2

BC = √3

Now,

∠B = 90°

∠A = 60°

∠C = 180 - (90 + 60) = 180 - 150 = 30°

cos C = cos 30° = √3 / 2

sin A = sin 60° = √3/2

Now,

Cos C x Sin A

= √3/2 x √3 / 2

= 3/2

Thus,

The value is 3/2.

Hello!

First, let's analyze the ordered pair in the form (x, y):

So, notice that x = 1 1/2 and y = -5. Knowing it, let's work in the cartesian plane:

According to the graph, this point will be in the fourth quadrant (because x is positive and y is negative).

Solution :

In this case we have to use \($\text{chi square test}$\) for the goodness of fit.

Null hypothesis is : \($H_0 :$\) Data follows the given distribution

Alternate hypothesis is : \($H_a:$\) Data do not follow the given distribution

The level of significance, \($\alpha = 0.05$\)

The test statistics is given by :

Chi square = \($\sum\frac{(O-E)^2}{E}$\)

Here O is the observed frequencies

         E is the expected frequencies

So we have, N = number of the categories = 4

df = degrees o freedom = N - 1

                                        = 4 - 1 = 3

Critical value  = \($7.814727764$\)

Calculating the table for the test statistics are given as :

  Category      prop.     O        E       \($\frac{(O-E)^2}{E}$\)

   A                   0.2     14       20         1.80

   C                   0.3     28       30         0.13

   M                  0.1        6        10          1.60

  P                    0.4      52       40         3.60

Total                  1        100      100        7.13

The test statics = chi square  = \($\sum\frac{(O-E)^2}{E}$\) = 7.13

\($X^2$\) statistics = 7.13

P-value = 0.067767248

P -value > \($\alpha = 0.05$\)

Therefore, we do not reject the \($\text{null hypothesis}$\). There is sufficient evidence to conclude that the data follows the given distribution. So there is sufficient evidence to conclude the given claim is true.

Answer:

-4/9

Step-by-step explanation:

We first calculate the first bracket.

[2/3-(-4/9)]

= (2/3+4/9) (we cancel out the negatives)

= (6/9+4/9) (common denominator)

= 10/9

Then we convert -2 1/2 into an improper fraction.

-2 1/2

= -5/2

Finally we calculate the division by swapping the numerator and denominator of -5/2.

10/9 / -5/2

= 10/9 * -2/5

= -20/45

= -4/9 (simplify the terms)

The slope of the line that contains the points (1,-9) and (-3,3) is -3 when the slope is y₂-y₁/x₂-x₁.

Given that,

We have two points they are (1,-9) and (-3,3).

We have to find the slope of the line that contains the points.

We know that,

The slope or steepness of a line is determined using the slope formula. It may be used to calculate any line's slope by comparing the change in the y-axis to the change in the x-axis. The slope of a line is the ratio of the change in the line's "y" coordinate to the change in its "x" coordinate.

Slope = y₂-y₁/x₂-x₁

So,

The points (1,-9) and (-3,3).

Slope = 3-(-9)/-3-1 = 3+9/-3-1 = 12/-4 = -3

Therefore, The slope of the line that contains the points (1,-9) and (-3,3) is -3 when the slope is y₂-y₁/x₂-x₁.

Answer: x < 5, see attached for the graph.

Step-by-step explanation:

   To solve, we will isolate the variable.

Given:

  5x - 15 < 10

Add 15 to both sides of the equation:

  5x < 25

Divide both sides of the equation by 5:

  x < 5

  For the graph, we will use an open circle because this is only less than (<), not less than and equal to.

  Then, since x is all values less than 5, we will shade our arrow to the left of 5. See attached.

The form that most quickly reveals the y intercept is

The y intercept is (0, 21/2)

The y-intercept is the point where a function or a curve intersects the y-axis. In other words, it is the value of the dependent variable (y) when the independent variable (x) is equal to zero.

In the form,  f(x) = 1/2 x² - 5x + 21/2 it is easier to see that eliminating x by plugging in 0 leaves 21/2 which is the y intercept

There is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.

In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.

To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.

A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.

Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

The revenue function is R = 25q, the cost function is C = 2000 + 20q, and the profit function is P = 5q - 2000.

The revenue function in terms of quantity can be calculated as follows:

Revenue (R) = q x p

Where: "q" is the quantity of units sold

"p" is the price per unit

At the break even point:

10,000 = 400p

p = 25 birr per unit

At the break even point, the total cost is equal to the total revenue:

Total cost = Total revenue = 10,000 birr

Fixed cost = 2000 birr

Variable cost (VC) = Total cost - Fixed cost

VC = 10,000 - 2000 = 8000 birr

The cost function in terms of quantity can be expressed as:

Cost (C) = FC + VC x q

C = 2000 + 20q

The profit function can be calculated as the difference between revenue and cost:

Profit (P) = R - C

P = 25q - (2000 + 20q)

P = 5q - 2000

Therefore, the revenue function is R = 25q,

the cost function is C = 2000 + 20q, and

the profit function is P = 5q - 2000.

Answer: The values of the six trigonometric functions for the angle formed by the positive x-axis and the line segment from (0,0) to (4,-3) are:

sinθ = -3/5

cosθ = 4/5

tanθ = -3/4

cscθ = -5/3

secθ = 5/4

cotθ = -4/3

Step-by-step explanation: To find the values of the six trigonometric functions (sine, cosine, tangent, cosecant, secant, and cotangent) of an angle formed by the positive x-axis and a line segment, we need to determine the lengths of the sides of the right triangle formed.

In this case, the line segment goes from (0,0) to (4,-3). The horizontal length (adjacent side) is 4 units, and the vertical length (opposite side) is -3 units (since it goes downward).

Now, we can calculate the trigonometric functions:

Sine (sinθ) = opposite/hypotenuse = -3/5

Cosine (cosθ) = adjacent/hypotenuse = 4/5

Tangent (tanθ) = opposite/adjacent = -3/4

Cosecant (cscθ) = 1/sinθ = -5/3

Secant (secθ) = 1/cosθ = 5/4

Cotangent (cotθ) = 1/tanθ = -4/3

Therefore, the values of the six trigonometric functions for the angle formed by the positive x-axis and the line segment from (0,0) to (4,-3) are:

sinθ = -3/5

cosθ = 4/5

tanθ = -3/4

cscθ = -5/3

Step-by-step explanation:

Given that,

Sheila 833 hot dogs every 44 minutes.

We need to find how minutes will take to eat 18 hot dogs​.

833 hot dogs = 44 minutes

1 hot dog = (44/833) minutes

For 18 hot dogs,

\(18\ \text{hot dogs}= \dfrac{44}{833}\times 18\\\\=0.950\ \text{minutes}\)

So, it will take \(0.950\ \text{minutes}\) to eat 18 hot dogs.

The mean is 0.477514 (rounded to 6 decimal places).

The standard deviation is 0.288919 (rounded to 6 decimal places).

To calculate the mean and standard deviation, we will use the following formulas:

Mean = (sum of all values) / (number of values)

Standard deviation = sqrt[(sum of (value - mean)^2) / (number of values)]

Using these formulas, we can calculate the mean and standard deviation for the given set of random numbers:

Mean = (0.937776 + 0.270012 + 0.243785 + 0.590701 + 0.824982 + 0.131805 + 0.879337 + 0.741998 + 0.254683 + 0.080259 + 0.419321 + 0.928220 + 0.958430 + 0.980182 + 0.263900 + 0.063119 + 0.762096 + 0.485612 + 0.662900 + 0.362242 + 0.724796 + 0.307736 + 0.305021 + 0.417052 + 0.054337 + 0.323357 + 0.069662 + 0.843387 + 0.353107 + 0.074262 + 0.735596 + 0.175095 + 0.390508 + 0.668932 + 0.029861 + 0.205228 + 0.387740 + 0.962169 + 0.646565 + 0.423914 + 0.754782 + 0.156719 + 0.773113 + 0.546335 + 0.323573 + 0.649740 + 0.214082 + 0.382383 + 0.383982 + 0.030539) / 50 = 0.477514

Therefore, the mean is 0.477514 (rounded to 6 decimal places).

Now we will calculate the standard deviation:

Standard deviation = sqrt[((0.937776 - 0.477514)^2 + (0.270012 - 0.477514)^2 + (0.243785 - 0.477514)^2 + ... + (0.382383 - 0.477514)^2 + (0.383982 - 0.477514)^2 + (0.030539 - 0.477514)^2) / 50] = 0.288919
