Absolute zero is -459.67 Fahrenheit. How many degrees above absolute zero is the freezing point of water?

Hi there!

\(\large\boxed{x = 11}\)

From the diagram, we can see that ΔAEF, and ΔACB are similar, isosceles triangles.

Therefore:

∠B and ∠F are congruent because they are corresponding angles, and ∠B and ∠E are congruent because of equal base angles in an isosceles triangle.

Therefore:

7x - 11 = 6x

Subtract 6x from both sides:

x - 11 = 0

Add 11 to both sides:

x = 11.

The function is not continous at x = 9

Step-by-step explanation:

To the left and right of the point x = 9, the graph would seem to continue at  f(x) = 0, however on the exact point x = 9 there is a hole in the graph allowing it to be equal to 1. Due to the hole in the graph, it is not continuous

Answer:

Mean for Male=72.13

Median for male = 65

Mean for Female= 79.93

Median for female= 83

There are differences in the results of mean and median for the males' data compared to the mean and median results calculated from the females' data.

Step-by-step explanation:

Mean for Male: 96 75 53 94 79 55 62 65 61 91 64 81 60 63 83 ​

X= 96, 75, 53, 94, 79, 55, 62, 65, 61, 91, 64, 81, 60, 63, 83 ​

Total number of value, n=15

Mean is average value, which gives: addition of X, divided by n

Mean= (96+75+53 +94+ 79+ 55+ 62+ 65+ 61+ 91+ 64+ 81+ 60+ 63+ 83) / 15

Mean= 1082 / 15

Mean=72.13

Median for male: 96 75 53 94 79 55 62 65 61 91 64 81 60 63 83 ​

The values should be rearranged in numerical order to get the middle value

53 55 60 61 62 63 64 65 75 79 81 83 91 94 96

The middle value is the 8th value since there are 15 values

Median = 65

Mean for Female: 71 73 92 86 90 67 89 76 89 86 69 88 68 83 72

X= 71 73 92 86 90 67 89 76 89 86 69 88 68 83 72

Total number of value, n=15

Mean is average value, which gives: addition of X, divided by n

Mean= (71 +73+ 92 +86 +90 +67 +89+ 76+ 89+ 86+ 69+ 88+ 68+ 83+ 72) / 15

Mean= 1199 / 15 = 79.93

Median for female: 71 73 92 86 90 67 89 76 89 86 69 88 68 83 72

The values should be rearranged in numerical order to get the middle value: 67 68 69 71 72 73 76 83 86 86 88 89 89 90 92    

 The middle value is the 8th value since there are 15 values

Median = 83

There are differences in the results of mean and median for the males' data compared to the mean and median results calculated from the females' data.

Answer:y=4/x−4−3

Step-by-step explanation:Explanation:

translation of 4 units right

translation of 3 units down

y=f(x)→y=f(x−4)−3

Note that the coordinates of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4). (Option B)

To rotate a point 90 degrees  clockwise about a given point,we can follow these steps -

Translate the coordinates   of the given point so that the center of rotation is at the origin.   In this case,we subtract the coordinates   of the center (0,1) from the coordinates of point A (5,4) to get (-5, 3).

Perform the rotation by swapping the x and y coordinates and changing the sign of the   new x coordinate. In this case,we  swap the x and y coordinates of (-5, 3)   to  get (3, -5).

Translate the coordinates back to their original position   by adding the coordinates of the center (0,1)  to the result from step 2. In   this case, we add (0,1) to (3, -5) to get (3, -4).

Therefore, the coordinates   of the point A' after rotating 90 degrees clockwise about the point (0,1) are (3, -4).

Answer:

5a =5

Step-by-step explanation:

Answer:

\(a = \frac{5c-6b}{18b}\)

Step-by-step explanation:

\(5c = 3b(6a + 2)\)

\(\frac{5c}{3b} = (6a + 2)\)

\(\frac{5c}{3b}-2 = 6a\)

\(\frac{5c-6b}{3b} = 6a\)

As a result, choice C is the equation that best represents the algebraic tiles since we only need to determine the total or difference.

It is possible either multiply, distribute, add, or negate in mathematics. The trying to follow is how a expression is put together: Number, expression, and scientific operator The ingredients of a mathematical expression include numbers, variables, and operations (such as addition, subtraction, multiplication or division etc.) It is possible to combine expressions and phrases. An expressions, often known as an arithmetic operation, is any mathematical statement that contains variables, numerals, and a numerical operation between them. That instance, the word m there in given equation is separated from the terms 4m and 5 by the arithmetic symbol +, as is the variable m in the phrase 4m + 5.

To address this issue, we just need to determine the total or difference that yields 2x2 + 2x + 2

Option A: ( x2 + 4x -2) + (x2 - 2x - 4) = 2x2 + 2x - 6

Option B: ( x2 + 4x - 2 ) + ( x2 + 2x + 4 ) = 2x2 + 6x + 2

Option C: ( x2 + 4x - 2) - ( -x2 + 2x - 4)= x2 + 4x - 2 + x2 - 2x + 4

The value of test statistic is -5.83.

statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In other words, it is a mathematical discipline to collect, summarize data. Also, we can say that statistics is a branch of applied mathematics. statistic = (sample proportion - hypothesized  proportion)/ standard error.

The decimal system is a number system that uses ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) to represent all possible numbers. It is also known as the base-10 system because each digit represents a power of 10. For example, in the number 123, the digit 3 represents 10^0 (which is 1), the digit 2 represents 10^1 (which is 10), and the digit 1 represents 10^2 (which is 100). The decimal system is widely used in everyday life and is the most common number system used around the world.

Here, the sample proportion is 0.9 (90% of 1146 adults said they have a cell phone), and the hypothesized proportion is 0.97 (the claim that fewer than 97% of adults have a cell phone).

The standard error can be calculated as:

standard error = sqrt[(hypothesized proportion * (1 - hypothesized proportion)) / sample size]

Substituting the values, we get:

standard error = \(\sqrt{(0.97*0.03)/1146}\) = 0.012

Now, substituting all the values in the formula for the test statistic, we get:

test statistic = (0.9 - 0.97) / 0.012 = -5.83

Rounding to two decimal places, the value of the test statistic is -5.83.

Answer:

1 of the feet is 2 of the  feet

Step-by-step explanation:

The cotangent of the positive acute angle is tan(5π/12)

We can use the trigonometric identity:

cot(π - θ) = -cot(θ)

to rewrite cot(11π/12) as -cot(π/12):

cot(11π/12) = -cot(π - 11π/12) = -cot(π/12)

Now, we can use the identity:

cot(π/2 - θ) = tan(θ)

to rewrite -cot(π/12) as tan(π/12 - π/2):

-cot(π/12) = -1/tan(π/12) = tan(π/2 - π/12)

Therefore, cot(11π/12) can be written in terms of the cotangent of a positive acute angle as:

cot(11π/12) = -cot(π/12) = tan(π/2 - π/12) = tan(5π/12)

Answer:

A) b= 8 students

B)  1) 19/55   2) 28/55

Step-by-step explanation:

I'm sorry if I'm getting this whole concept wrong cause it felt way too easy to be right so I'm sorry if you get it wrong.

The reason the first question is 8 is because of the fact that you first have to add the students charted on the Venn-diagram and subtract that from 55, getting you to 8 students.

For the second one, the first part would be 19/55 becuase in the Venn-diagram it is shown that only 19 people passed both and so that be the numerator and the denominator would be the total of students, so it would be 55.

Same thing for part two except the fact that you have to add the students who only passed one subject, so combine 17 and 11, getting you to 28, thus getting the answer 28/55.

\(\dfrac{y^2}{225} -\dfrac{x^2}{216}=1\)

Step-by-step explanation:

For a hyperbolic mirror the two foci are 42 cm apart.

The distance between the foci = 2c.

Therefore:

The distance of the vertex from one focus = 6 cm

The distance of the vertex from the other focus = 36 cm

2a=36-6=30

Now:

\(c^2=a^2+b^2\\21^2=15^2+b^2\\b^2=21^2-15^2\\b^2=216\\b=6\sqrt{6}\)

If the transverse axis lies on the y-axis, and the hyperbola is centered at the origin. Then the hyperbola has an equation of the form:

\(\dfrac{y^2}{a^2} -\dfrac{x^2}{b^2}=1\)

Therefore, the equation of the hyperbola is:
