Step-by-step explanation:

because the value of x .

The diagram only shows that angles M and B are supplementary ( add up to 180 degrees) and that angel 4x is adjacent to angel M.However, there is no information about the measure of angle B or angel M, so we cannot determine the value of x

The length of side AB is about 5.87 units.

The triangle ABC is a right angle triangle. A right angle triangle is a triangle that has one of its angles as 90 degrees.

Therefore, let's find the length AB in the right triangle.

Using trigonometric ratios,

cos 33 = adjacent / hypotenuse

Therefore,

Adjacent side = AB

hypotenuse side = 7 units

cos 33° = AB / 7

cross multiply

AB = 7 cos 33

AB = 7 × 0.83867056794

AB = 5.87069397562

AB = 5.87 units

The average score of the spelling test is 90.6%

To find the average score of the test, we need to add up all the scores and divide by the total number of students. We can think of the average score as the "typical" or "representative" score of the entire class.

First, let's add up all the scores:

2(100) + 9(95) + 10(90) + 3(80) + 1(70) = 200 + 855 + 900 + 240 + 70 = 2265

Next, we divide by the total number of students:

Average score = (2 + 9 + 10 + 3 + 1) / 25 * 100% = 25 / 25 * 100% = 90.6%

Therefore, the average score of the spelling test is 90.6% when rounded to one decimal place.

The value of x in dimensions of similar quadrilateral is 9.375 cm.

To determine the value of x, we need to use the fact that similar polygons have proportional sides.

Let's start by identifying the corresponding sides of the similar quadrilaterals:

AB/EF = BC/FG = CD/GH = DA/HE

We are given the lengths of some of these sides:

AB = 10 cm, EF = 8 cm, HE = 12 cm, and GH = 6 cm.

Let's substitute these values into the equation:

10/8 = BC/6

Simplifying, we get:

BC = (10/8) x 6 = 7.5 cm

Now we can use another equation to find x:

CD/GH = BC/FG

Substituting the values we know, we get:

x/6 = 7.5/4.8

Simplifying, we get:

x = (6 x 7.5)/4.8 = 9.375 cm

Explanation:

The key word here is "desired". We wish to make the errors as small as possible. The smallest any individual error can get is 0. Adding the entire collection of zeros will sum in a total of zero.

An error of zero means we hit the mark exactly. The unfortunate reality is that error is going to happen, so we'll have some positive error values with any regression line (or curve). It's only when all points are on the same line is when we have zero error and perfect interpolation rather than regression.

Again, the question is asking about desired error and the ultimate goal is to make the error zero. The next best thing is to minimize it as small as possible.

The function to represent the arithmetic sequence is y = 0.17x + 0.71, and an envelop weighing 8 ounces cost $2.07

An equation is an expression that shows the relationship between variables and numbers.

An arithmetic sequence is in the form:

\(a_n=a_1+(n-1)d\\\\where\ a_1=first\ term,d=common\ difference\)

Let y represent the price to send an envelop of x ounces. The arithmetic sequence is:

y = a₁ + (x - 1)d

Given that the first ounce is 88 cents($0.88), hence a₁ = 0.88. Eadh additional ounce is 17 cents (0.17), hence d = 0.17. Therefore:

y = 0.88 + (x - 1)(0.17)

y = 0.17x + 0.71

For a cost of $2.07:

2.07 = 0.17x + 0.71

x = 8 ounces

The function to represent the arithmetic sequence is y = 0.17x + 0.71

Draw out a 10 squares.

Shade in 4 of them to represent 4/10 = 0.40 = 0.4

Then use another color to shade another 4 squares. You should have 4+4 = 8 squares shaded, out of 10 total, giving 8/10 = 0.80 = 0.8

This is one visual way to see how 0.4 x 2 = 0.8

In other words, 0.4 x 2 means we have two copies of 0.4 added together. You could write it as 0.4 x 2 = 0.4 + 0.4 = 0.8 if you wanted.

When x = 13, the equation that is true is option D) 5(x - 9) = 20.

To determine which equation is true when x = 13, we can substitute the value of x into each equation and see which equation holds true. Let's go through each option:

A) 3(18 - x) = 67

Substituting x = 13:

3(18 - 13) = 67

3(5) = 67

15 = 67

The equation is not true when x = 13. Therefore, option A is false.

B) 4(9x) = 23

Substituting x = 13:

4(9*13) = 23

4(117) = 23

468 = 23

Again, the equation is not true when x = 13. Therefore, option B is also false.

C) 2(x - 3) = 7

Substituting x = 13:

2(13 - 3) = 7

2(10) = 7

20 = 7

Once again, the equation is not true when x = 13. Therefore, option C is false as well.

D) 5(x - 9) = 20

Substituting x = 13:

5(13 - 9) = 20

5(4) = 20

20 = 20

Step-by-step explanation:

Given

\(Sets:\{0,1,3,4,6,12\}\)

Gary: \(6>0.5t\)

Nancy: \(30 -t \le 18\)

Jamal: \(12 \le t+12\)

Required

Which of the inequalities is/are true

Gary: \(6>0.5t\)

\(6>0.5t\)

Divide both sides by 0.5

\(\frac{6}{0.5} > \frac{0.5t}{0.5}\)

\(12 > t\)

Rewrite as:

\(t < 12\)

Gary's inequality is false because: \(12 = 12\)

Nancy: \(30 -t \le 18\)

\(30 -t \le 18\)

Collect like terms

\(-t \le 18 - 30\)

\(-t \le -12\)

Divide both sides by -1

\(t \ge 12\)

Nancy's inequality is incorrect because: 0,1,3,4 and 6 are less than 12

Jamal: \(12 \le t+12\)

\(12 \le t+12\)

\(12 - 12 \le t\)

\(0 \le t\)

Rewrite as:

\(t \ge 0\)

Jamal's inequality is correct because: 0,1,3,4,6 and 12 \(\ge 0\)

The probability that the mean fill is more than 84.8 ounces is 0.39358

From the question, the given parameters about the normal distribution are

Mean value of the set of data = 88.2

Standard deviation value of the set of data = 1.3

The actual data value = 88.2

The z-score of the data value is calculated using the following formula

z = (x - mean value)/standard deviation

Substitute the given parameters in the above equation

z = (88.2 - 87.9)/1.3

Evaluate the difference of 88.2 and 87.9

z = 0.3/1.3

Evaluate the quotient of 0.3 and 1.1

z = 0.23

The probability that the mean fill is more than 88.2 ounces is then calculated as:

P(x > 88.2) = P(z > 0.23)

Answer:

The answer is 13

Step-by-step explanation:

First, you replace x with 2. Then you multiply 4 and 2 which you get 8. Lastly, you add 8 and 5 so you get 13.

The domain of (s - t)(x) in interval notation is (-∞, -8) U (-8, 5) U (5, 8) U (8,

∞).

To find (s - t)(x), we subtract the function t(x) from s(x).

s(x) =\((x - 5)/(x^2 - 64)\)

t(x) = (x - 8)/(5 - x)

To subtract the functions, we need a common denominator. In this case, we can use (x^2 - 64) as the common denominator.

(s - t)(x) =\([(x - 5)/(x^2 - 64)] - [(x - 8)/(5 - x)]\)

To simplify the expression, we need to factor the denominators and simplify further:

\((x^2 - 64) = (x - 8)(x + 8)\)

(5 - x) = -(x - 5)

Substituting these into the expression, we get:

(s - t)(x) = [(x - 5)/(x - 8)(x + 8)] - [(x - 8)/-(x - 5)]

Next, we need to find a common denominator for the two fractions. The common denominator will be (x - 8)(x + 8)(x - 5).

(s - t)(x) = [(x - 5)(-(x - 5))/((x - 8)(x + 8)(x - 5))] - [(x - 8)(x + 8)/((x - 8)(x + 8)(x - 5))]

Simplifying further:

(s - t)(x) = \([-(x - 5)^2 - (x - 8)(x + 8)]/[(x - 8)(x + 8)(x - 5)]\)

The domain of the function (s - t)(x) is the set of values for which the denominator is non-zero, since division by zero is undefined.

The denominator (x - 8)(x + 8)(x - 5) will be non-zero as long as x is not equal to 8, -8, or 5.

Answer:

In mathematics, the extrema of a function refer to the maximum and minimum values that the function can take on. These values can be local extrema, which occur within a certain range of the function, or global extrema, which are the maximum and minimum values over the entire domain of the function.

To find the extrema of a function, one can use a variety of techniques, such as taking the derivative of the function and setting it equal to zero to find the points of stationary values, or using the second derivative test to determine whether a stationary point is a local maximum or minimum.

Interpreting the extrema of a function can provide valuable information about the behavior of the function. For example, the global maximum of a function might represent the highest possible value that the function can attain, while the global minimum might represent the lowest possible value. Local extrema can also be important, as they can indicate changes in the slope or concavity of the function, which can have important implications for applications such as optimization or modeling real-world phenomena.
