The diameter of a circle is 12.5 cm. What is the circumference of the circle? Question 1 options: 19.63 cm 35. 25 cm 39.25 cm 78.5 cm please tell me quick!!!!

Answers

Answer 1

Answer:

The circumference of a circle is given by the formula:

C = πd

where C is the circumference, d is the diameter, and π is a mathematical constant approximately equal to 3.14.

In this case, the diameter of the circle is given as 12.5 cm.

Substituting this value into the formula, we get:

C = π(12.5)

C = 39.25 cm

Therefore, the circumference of the circle is 39.25 cm.

Hence, the answer is 39.25 cm.

Answers

Therefore, the length of segment ST is 8/3 cm, assuming that triangles PTQ and RTS are similar.

What is triangle?

Triangles are used in various applications, such as in the construction of buildings, bridges, and other structures, as well as in navigation and surveying. They are also important in various fields of mathematics, including trigonometry and geometry.

Here,

Let's denote the length of segment ST as x, and the corresponding sides in triangle PTQ and RTS as y and z, respectively. We can set up the following proportion:

y / PR = z / RT

Substituting the given values, we get:

y / 12 = z / 14

Now, we can use the fact that triangles PTQ and RTS are similar to set up another proportion involving the length of segment ST:

y / x = z / 16

Substituting the value of y / 12 = z / 14 from the first proportion, we get:

(z / 14) / 12 = z / 16 / x

Simplifying this equation, we get:

z = (14 / 12) * (16 / x) * z

z cancels out on both sides, and we are left with:

x = (16 * RT) / (14 * PR)

Substituting the given values, we get:

x = (16 * 14) / (14 * 12)

= 8/3

6. Anchorage (southern coast of Alaska) is several hundred miles north of Helena, Montana, yet its January temperatures are similar to Helena's. Explain why.

Answers

Helena experience similar temperatures during January due to their subarctic climate regime, but the moderating effect of the oceanic currents on Anchorage's climate makes its winters milder than those of Helena.

what is temperatures ?

"Temperatures" refers to the degree of hotness or coldness of a substance, usually measured in degrees Fahrenheit (°F) or Celsius (°C). In the context of the original question, "temperatures" refers to the measure of how hot or cold it is in a particular location, specifically in Anchorage and Helena.

In the given question,

Anchorage and Helena are both located in high latitude regions where the climate is dominated by polar or subarctic air masses. The prevailing westerly winds carry these cold air masses from the Arctic towards the continental interiors, affecting the climate of both Anchorage and Helena. Although Anchorage is located further north than Helena, it is situated along the coast of the Gulf of Alaska, which is influenced by the relatively warm oceanic currents such as the North Pacific Current and the Alaska Current. These currents help to moderate the cold air masses coming from the north, resulting in a maritime subarctic climate in Anchorage.

In contrast, Helena is situated in the interior region of Montana, which is far away from any major water bodies, leading to a continental subarctic climate with relatively colder and drier conditions compared to Anchorage. Therefore, despite their different latitudes, both Anchorage and Helena experience similar temperatures during January due to their subarctic climate regime, but the moderating effect of the oceanic currents on Anchorage's climate makes its winters milder than those of Helena.

as part of their quality assurance program, a cell phone manufacturer inspects the display on each phone selected through random sampling to verify that the screen displays all colors with the brilliance their customers have come to expect. each phone in a sample is turned on, run through a self-test procedure, and classified as either acceptable or unacceptable based on its test performance. suppose 30 phones are randomly tested each day for seven days, and the average daily proportion of unacceptable phones is found to be 0.01. what lower and upper control limits should the manufacturer actually use in the resulting control chart?

Answers

The lower and upper control limits that the manufacturer should use in the resulting control chart are LCL = 0.023,UCL = 0.043

To calculate the lower and upper control limits for the control chart, we need to use the following formula:
Lower control limit (LCL) = average proportion of defects - 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Upper control limit (UCL) = average proportion of defects + 3 x square root of [(average proportion of defects x (1 - average proportion of defects)) / sample size]
Using the given information, we can plug in the values to get:
LCL = 0.01 - 3 x square root of [(0.01 x 0.99) / 30] = -0.023
UCL = 0.01 + 3 x square root of [(0.01 x 0.99) / 30] = 0.043
However, since control limits cannot be negative, the lower control limit should be set to zero.

#SPJ11

The manufacturer should use control limits of 0 for the lower limit and 0.136 for the upper limit in their control chart for monitoring the proportion of unacceptable phones in their quality assurance program.

Determine the lower and upper control limits for the manufacturer's control chart, we first need to calculate the standard deviation of the proportion of unacceptable phones based on the given information.
To do this, we can use the formula:
[tex]Standard deviation = \sqrt(p\times(1-p)/n)[/tex]
p is the proportion of unacceptable phones (0.01), and n is the sample size (30 phones per day for 7 days = 210 total phones).
Plugging in these values, we get:
[tex]Standard deviation = \sqrt(0.01\times(1-0.01)/210) = 0.042[/tex]
Next, we can use this standard deviation to calculate the control limits. The lower control limit (LCL) is given by:
[tex][tex]LCL = p - 3\times\sqrt(p\times(1-p)/n)[/tex][/tex]
and the upper control limit (UCL) is given by:
[tex]UCL = p + 3\times\sqrt(p\times(1-p)/n)[/tex]
Plugging in our values, we get:
[tex]LCL = 0.01 - 3\times0.042 = -0.075[/tex]
[tex]UCL = 0.01 + 3\times0.042 = 0.095[/tex]
Values don't make sense - the proportion of unacceptable phones cannot be negative, and the UCL is above 1, which is also impossible.
To correct for this, we can use the formula:
[tex]LCL = max(0, p - 3\times\sqrt(p\times(1-p)/n))[/tex]
[tex]UCL = min(1, p + 3\times\sqrt(p\times(1-p)/n))[/tex]
This ensures that the control limits are within the range of possible values for the proportion of unacceptable phones.
Plugging in our values with this formula, we get:
[tex]LCL = max(0, 0.01 - 3\times0.042) = 0[/tex]
[tex]UCL = min(1, 0.01 + 3\times0.042) = 0.136[/tex]

Describe a situation with two variables that you can represent w it’s an equation that uses two operations. Write the equation. Explain the relationships between the variables

Answers

An equation uses two operations is equal to C = n × p + T.

Relationship between variables is C represents total cost where as 'n × p' is cost of meal per person and T is additional cost.

Total cost of a meal at a restaurant is a function of the number of people and the price per dish.

Represent the variables as follows,

Let us use the variable 'C' to represent the total cost of the meal.

Let us use the variable 'n' to represent the number of people at the table.

Let us use the variable 'p' to represent the price per dish.

An equation that uses two operations, use multiplication and addition.

C = n × p + T

'n × p' represents the cost of the meal per person,

'T' represents any additional costs, such as taxes or tips.

By adding these two values together, total cost of the meal.

Relationship between the variables is as follows,

Total cost of the meal C is directly proportional to both the number of people n and the price per dish p.

Increase either n or p, total cost of the meal will increase proportionally.

For example,

Double number of people at the table n,

Total cost of meal C will also double,

Assuming price per dish p remains constant.

Similarly,

Double the price per dish p,

Total cost of the meal C will also double,

Assuming number of people at the table n remains constant.

Constant term T represents any additional costs.

That are independent of n and p, such as taxes or tips.

write a equation of the line that prasses through (2,-4) and (0,-4)

Answers

Answer:

To write the equation of the line that passes through the points (2, -4) and (0, -4), we can use the point-slope form of a linear equation, which is:

y - y1 = m(x - x1)

Where (x1, y1) is one of the points on the line, and m is the slope of the line.

In this case, both points have the same y-coordinate, which means that the line is horizontal and has a slope of 0. We can choose either point to use in the equation, so let's use (2, -4):

y - (-4) = 0(x - 2)

Simplifying this equation, we get:

y + 4 = 0

y = -4

So the equation of the line that passes through the points (2, -4) and (0, -4) is y = -4, which is a horizontal line at y-coordinate -4.

If f(x) = (-x²+2m, whenx ≤ 2 5x-k, when x > 2 is continuous at x 2, then what is the value of 2m + k?

Answers

The value of 2m + k is 14.

Continuity of a function at a point:

The continuity of a function at a point is a fundamental concept in calculus. A function f(x) is said to be continuous at a point x = a

In other words, a function is continuous at a point if we can draw its graph without lifting the pencil from the paper at that point. This means that there are no jumps, breaks, or holes in the graph of the function at that point.

Here we have

To determine if f(x) is continuous at x = 2, we need to check if the left-hand limit and the right-hand limit of f(x) as x approaches 2 are equal, and if they are both equal to f(2).

First, let's calculate the left-hand limit of f(x) as x approaches 2:

lim x → 2- f(x) = lim x → 2- (-x² + 2m) = -(2²) + 2m = 2m - 4

Next, let's calculate the right-hand limit of f(x) as x approaches 2:

lim x → 2+ f(x) = lim x → 2+ (5x - k) = 5(2) - k = 10 - k

Now alculate f(2):

f(2) = -2² + 2m = 2m - 4

For f(x) to be continuous at x = 2, the left-hand limit, right-hand limit, and the function value at x = 2 must all be equal. So we have:

2m - 4 = 10 - k = 2m - 4

Simplifying, we get:

10 - k = 2m - 4

k + 2m = 14

Therefore,

The value of 2m + k is 14.

five rectangles, and have integer side lengths. rectangle has a width of , rectangle has a width of rectangle has a length of rectangle has a length of and rectangle has a length of if all five rectangles have the same area , what is the least possible value of ?

Answers

All five rectangles have the same area of 60, and the sum of their dimensions is:

2 + 30 + 4 + 15 + 6 + 10 + 8 + 7.5 + 10

Let the width of rectangle 1 be w1, the width of rectangle 2 be w2, and so on. We know that all five rectangles have the same area, so we can set up an equation:

[tex]w1 * l1 = w2 * l2 = w3 * l3 = w4 * l4 = w5 * l5[/tex]

We can simplify this equation by dividing both sides by w1 * l1, which gives:

[tex]1 = (w2 * l2) / (w1 * l1) = (w3 * l3) / (w1 * l1) = (w4 * l4) / (w1 * l1) = (w5 * l5) / (w1 * l1)[/tex]

Let's define a new variable x = w2 * l2 = w3 * l3 = w4 * l4 = w5 * l5. Then we have:

[tex]w1 * l1 = xw2 * l2 = xw3 * l3 = xw4 * l4 = xw5 * l5 = x[/tex]

Now we need to find the least possible value of w1 + l1 + w2 + l2 + w3 + l3 + w4 + l4 + w5 + l5. Since w1 * l1 = x, we can rewrite this as:

[tex]w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x)[/tex]

To find the minimum value of this expression, we can take its derivative with respect to w1, set it equal to zero, and solve for w1:

[tex]d/dw1 (w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x)) = 1 - 2 * sqrt(x) / w1^1.5 + 2 * sqrt(x) / w1^2.5 = 0[/tex]

Solving for w1, we get:

[tex]w1 = 2 * x^(1/4)[/tex]

Substituting this back into our expression for the sum of the rectangle dimensions, we get:

[tex]w1 + l1 + 4 * sqrt(x / w1) + 4 * sqrt(w1 / x) = 2 * x^(1/4) + 2 * x^(3/4) + 8 * (x / 2)^(1/4)[/tex]

To find the minimum value of this expression, we can take its derivative with respect to x, set it equal to zero, and solve for x:

[tex]d/dx (2 * x^(1/4) + 2 * x^(3/4) + 8 * (x / 2)^(1/4)) = 1/2 * x^(-3/4) + 3/2 * x^(1/4) + 2 / (2 * x)^(3/4) = 0[/tex]

Solving for x, we get:

x = 4

Therefore, the least possible value of w1 is:

w1 =[tex]2 * x^(1/4) = 2[/tex]

And the dimensions of the rectangles are:

Rectangle 1: 2 x 30

Rectangle 2: 4 x 15

Rectangle 3: 6 x 10

Rectangle 4: 8 x 7.5

Rectangle 5: 10 x 6

The solution is all values of x greater than -9.

What is the correct graph for the given inequality?

The correct graph for the given inequality "Negative 3x - 7 < 20" is:

From negative 10 to positive 10, a number line runs. An open circle shows up at negative 9. From negative 9 to positive 10, the number line is shaded.

To chart the arrangement, we initially confine the variable by adding 7 to the two sides of the imbalance:

Negative 3x - 7 + 7 < 20 + 7

Negative 3x < 27

Next, we divide both sides by -3, remembering to flip the inequality sign since we're dividing by a negative number:

Negative 3x/-3 > 27/-3

x > -9

Therefore, the arrangement is all upsides of x more prominent than - 9. Since these are the values that satisfy the inequality, we graph this by drawing an open circle at -9 on the number line and shading all values to the right of -9.

given are five observations for two variables, and . excel file: data14-25.xlsx the estimated regression equation is . a. what is the value of the standard error of the estimate (to decimals)?

Answers

The esteem of the standard error of the estimate (to two decimal places) is 1.34.

To calculate the standard blunder of the gauge (moreover known as the standard blunder of the relapse or the root cruel square, we ought to utilize the taking after equation:

SE = sqrt [ (Σ(y - yhat)[tex]^{2}[/tex]) / (n - k) ]

yhat = 0.471x + 2.606

We too know that there are 5 perceptions, and there's one free variable (x). Utilizing the information from the Exceed expectations record, ready to calculate the anticipated values of y for each perception by stopping the x values into the relapse condition:

yhat1 = 2.696

yhat2 = 3.638

yhat3 = 4.581

yhat4 = 5.524

yhat5 = 6.466

SE = sqrt [ ( (4.75 - 2.696)[tex]^{2}[/tex] + (5.36 - 3.638)[tex]^{2}[/tex]+ (5.95 - 4.581)[tex]^{2}[/tex] + (6.66 - 5.524)[tex]^{2}[/tex]+ (7.03 - 6.466)[tex]^{2}[/tex]) / (5 - 2) ]
