Answer:

52

Step-by-step explanation:

the total is 180

so u add 61 and 67 which gives u 128

so u subtract 180 and 128 which gives u 52

hope this helps

Answer:the answer is 52

Step-by-step explanation:

First a triangle equals 180 degrees. Knowing that Q is 67 degrees and R is 61 degrees 67 plus 61 is 128. 180 subtract 128 is 52 therefore S is 52 degrees.

The kind of model that best describes this set of data is linear relationship. (Option A)

A linear relationship or linear association refers to a statistical term which is used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. In the given case, if the set of data is plotted on the graph, it will show a straight-line. It can also be determined by calculating the slope between a few points and see if the slope is the same. In the attached graph, it can be seen that the data is linear.

The t-distribution value is -1.67 for the given mean samples of 35 and 45. Thus, option B is correct.

M₁ = 35

M₂ = 45

SM1-M2 = 6.00

The t-value or t-distribution formula is calculated from the sample mean which consists of real numbers. To calculate the t-value, the formula we need to use here is:

t = (M₁ - M₂) / SM1-M2

Substituting the given values into the formula:

t = (35 - 45) / 6.00

t = -10 / 6.00

t = -1.67

Therefore, we can conclude that the value of t is -1.67 for the samples given.

Answer: 6 hours

Step-by-step explanation:

6.5x = 39

6=x

Answer:

the first and fourth quadrants

Step-by-step explanation:

We have that the time found hours is given on the x-axis and that the temperature is represented on the y-axis.

Let's first analyze time:

Time cannot be negative, therefore, the x coordinate cannot be negative therefore, for the x axis, we can use the first and fourth quadrants

Second let's analyze the temperature:

The temperature can be negative, therefore, the coordinate and can be positive or negative therefore, that for the y axis, we can use all four quadrants.

If we combine the two previous conditions, we can deduce that we can only use the first and fourth quadrants to represent the required data.

To find the number of machines that minimize the unit cost, we need to find the value of x that minimizes the function C(x). We can do this by finding the critical points of C(x) and determining which one corresponds to a minimum.

First, we take the derivative of C(x) with respect to x:

C'(x) = 1.2x - 372

Then, we set C'(x) equal to zero and solve for x:

1.2x - 372 = 0

1.2x = 372

x = 310

So the critical point is x = 310.

To determine whether this critical point corresponds to a minimum or a maximum, we need to examine the second derivative of C(x):

C''(x) = 1.2

Since C''(x) is positive for all values of x, we know that the critical point x = 310 corresponds to a minimum.

Therefore, the number of machines that must be made to minimize the unit cost is 310.

? = 5

Step-by-step explanation:

You use cross-multiplying. Let's say ? is x.

First step:  \(\frac{30}{x}=\frac{48}{8}\)

Second step: You cross them so 30(8)= 280. 48(x)= 48x.

Third step: \(\frac{280}{48x}\)= 5

To double check this:

30/5= 6

48/8= 6

42/7= 6

Step-by-step explanation:

1 = x^2 - 6x

Adding 9 to both sides, we get

1 + 9 = x^2 - 6x + 9

The greatest possible value of ab + bc+ cd+da is 576.

A permutation refers to a selection of objects from a set of objects in which order matters. A phone number is an example of a ten number permutation; it is drawn from the set of the integers 0-9, and the order in which they are arranged in matters. Another example of a permutation we encounter in our everyday lives is a passcode or password. To unlock a phone using a passcode, it is necessary to enter the exact combination of letters, numbers, symbols, etc., in an exact order. In cases where the order doesn't matter, we call it a combination instead.

ab+bc+cd+da

= ab + da  + bc + dc

= a(b + d) + c (b + d)

= (a + c) (b + d)

We choose any 2 of the 4 numbers to occupy the first set of parentheses without regard to order. Thus, the second sum is fixed.

⁴C₂ = 6

So, we  can permute the order of the parentheses' sums in two ways.

∴  6 / 2   =   3 different values

No matter the arrangements, the only possible values are

(9 + 11) (13 + 15)  = 360

(9 + 13) (11 + 15) = 572

(9+ 15) (13 + 11) = 576

The largest value out of the three is 576.

Thus, the greatest possible value of ab + bc+ cd+da is 576.

Answer:The third statement is true: The graph of y=log (x) + 4 is the graph of y=log(x) translated 4 units up.

Step-by-step explanation:

Using translation concepts, it is found that the graph of y=logx - 4 is the graph of y = logx translated 4 units right.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

here, we have,

In this problem, the parent function is:

y=logx

The translated function is given by:

y=logx - 4

now, here, we have to find the translation, which is done in the transformation of y=logx to y=logx - 4

here, we noticed that,

The change was in the domain, in which x→x-4 , which means that the function was translated 4 units right.

The statements that best describes the relationship between the mean and median of the distribution of ages in the histogram is the option (C)

(C) The mean is most likely less than the median because the distribution is skewed to the left

A histogram graphically represents the distribution of data, which consists of rectangles, representing the range of values, divided into intervals which is represented as the width of each rectangle, and the number of values within each interval, represented as the height of the rectangle.

Please find attached the possible histogram in the question, created with MS Excel

The histogram indicates that the distribution of the ages is skewed to the left, based on the tail consisting of four smaller rectangles to the left and  two smaller rectangles to the right of the modal frequency interval of 35 to 40. The left skewed histogram indicates that there are a higher frequency of the older age groups.

The mean of a left skewed histogram is usually less than the median.

The correct option is therefore, option (C)

The options in the question are;

(A) The mean and median are equivalent because the histogram has a symmetric distribution

(B) The mean is less than the median because the distribution is skewed to the right

True. The rule of thirds is a photography and visual arts guideline that involves dividing an image into thirds using two horizontal lines and two vertical lines, and then placing the image's most important elements at the intersection points or along the lines.

This aids in the creation of a balanced and visually appealing composition. This results in nine rectangular areas of equal size, with four intersection points where the lines cross.

The rule of thirds principle suggests that the points of intersection or the lines themselves are ideal places to position the composition's most important elements. The resulting image is more visually balanced and pleasing to the eye as important elements are placed in these areas.

It is important that, however, that the rule of thirds is not a hard and fast rule, and that there were times when breaking it can result in more dynamic and interesting compositions. The rule of thirds is merely a tool for artists and photographers to use in order to create more effective and engaging images.

Answer: D.

Step-by-step explanation:

You can start out with the form AX = B and solve for matrix X that would yield the answer

Then X = (A^-1)(B)

A = [1    -1]

      [1     1]

A^-1 = (1/(1 - (1)(-1)))*[1    1]

                             [-1   1]

which can be written as (1/2) * [1    1]

                                                  [-1   1]

B = [26]

     [6]

(A^-1)(B) = (1/2)*[1    1] [6]

                        [-1   1] [26]

= (1/2)*[32]
