Step-by-step explanation:

Mean

The word mean, which is a homonym for multiple other words in the English language, is similarly ambiguous even in the area of mathematics. Depending on the context, whether mathematical or statistical, what is meant by the "mean" changes. In its simplest mathematical definition regarding data sets, the mean used is the arithmetic mean, also referred to as mathematical expectation, or average. In this form, the mean refers to an intermediate value between a discrete set of numbers, namely, the sum of all values in the data set, divided by the total number of values. The equation for calculating an arithmetic mean is virtually identical to that for calculating the statistical concepts of population and sample mean, with slight variations in the variables used

Median

The statistical concept of the median is a value that divides a data sample, population, or probability distribution into two halves. Finding the median essentially involves finding the value in a data sample that has a physical location between the rest of the numbers. Note that when calculating the median of a finite list of numbers, the order of the data samples is important. Conventionally, the values are listed in ascending order, but there is no real reason that listing the values in descending order would provide different results. In the case where the total number of values in a data sample is odd, the median is simply the number in the middle of the list of all values. When the data sample contains an even number of values, the median is the mean of the two middle values. While this can be confusing, simply remember that even though the median sometimes involves the computation of a mean, when this case arises, it will involve only the two middle values, while a mean involves all the values in the data sample. In the odd cases where there are only two data samples or there is an even number of samples where all the values are the same, the mean and median will be the same

Answer:

B. y = -3/8x - 4

Step-by-step explanation:

Given equation: 3x - 8y = 12

Find a parallel line that matches one of the equations shown.

First, find the slope by solving for y:

3x - 8y = 12

8y = -3x + 12

y = -3/8x + 12/8

y = -3/8x + 3/2

Slope m = -3/8

Since the slope of a line parallel is the same slope, the only equation that fits the conditions is B because in the form y = mx + b, m = -3/8

Answer:

To make f continuous at [tex]x=2[/tex], [tex]f(2)[/tex] should be defined [tex]x = 2.[/tex]

Step-by-step explanation:

A function, let say [tex]f(x)[/tex], is defined at [tex]x = c[/tex] is continuous at [tex]x = c[/tex]

If the limit of [tex]f(x)[/tex] as [tex]x[/tex] approaches [tex]c[/tex] is equal to the value of [tex]f(x)[/tex] at  [tex]x = c[/tex].

Mathematically it is written as:

if

[tex]\lim _{x\to c}\:f\left(x\right)=f\left(c\right)[/tex]

then

[tex]f(x)[/tex] is continuous at  [tex]x = c[/tex].

So from the above definition, we conclude that:

To make f continuous at [tex]x=2[/tex], [tex]f(2)[/tex] should be defined [tex]x = 2.[/tex]

i.e.

if

[tex]\lim _{x\to 2}\:f\left(x\right)=f\left(2\right)[/tex]

then

[tex]f(x)[/tex] is continuous at  [tex]x = 2[/tex].

To make f continuous at x=2, define f(2) to be equal to 4. This makes the left-hand limit, right-hand limit, and function value at x=2 all equal to 4, which satisfies the definition of continuity.

To make a function continuous at a point, the left-hand limit and right-hand limit at that point must be equal to the function's value at that point. In other words, if a function is continuous at x=a, then

[tex]\lim_{x \to a^+} f(x)=f(a)[/tex]

Therefore, to make f continuous at x=2, we must define f(2) to be equal to the limit of f(x) as x approaches 2 from both the left and the right.

We can see that the limit of f(x) as x approaches 2 from the left is 4. This is because f(x) approaches 4 as x approaches 2 from the left, even though f(2) is undefined.

We can also see that the limit of f(x) as x approaches 2 from the right is 4. This is because f(x) approaches 4 as x approaches 2 from the right, even though f(2) is undefined.

Therefore, to make f continuous at x=2, we must define f(2) to be equal to 4.

Answer:

25 and 30

Step-by-step explanation:

because one angle measures 280 and the other 25 you add it.

280 + 25 = 305

Since there is 360 degrees in a quadrilateral you subtract

360 - 305 = 55

the other 2 measures are in the ratio of 5:6

So add those to ratios 5 + 6 = 11

55/11 = 5

multiply it by the ratio

5 * 5 = 25

5 * 6 = 30

Rate of interest (r) = 3%

Time (T) = 1 years

To find the interest calculated compound in 1 year.

Formula

Amount = P[tex](1+\frac{r}{100} )^{T}[/tex]

Putting the given values we get,

Amount = 2000[tex](1+\frac{3}{100} )^{1}[/tex]

= 2060

So,

The interest = 2060-2000 = 60

Answer:

∠ RQU = 25°

Step-by-step explanation:

The opposite angles of an inscribed circle are supplementary, thus

∠ URS + ∠ UTS = 180°, that is

∠ URS + 124° = 180° ( subtract 124° from both sides )

∠ URS = 56°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ URS is an external angle to Δ QUR, that is

∠ RQU + 31° = 56° ( subtract 31° from both sides )

∠ RQU = 25°

The area of the rhombus is a rational number, specifically 5/12, which can be expressed as a fraction. Therefore, we can conclude that when d1 is a terminating decimal and d2 is a repeating decimal, the area of the rhombus can be expressed as a rational number.

When d1 is a terminating decimal and d2 is a repeating decimal, we can conclude that the area of the rhombus can be expressed as a rational number.

To see why, consider the formula for the area of a rhombus: A = (1/2)d1d2. If d1 is a terminating decimal, it can be expressed as a finite fraction.

For example, if d1 = 1.25, then d1 can be expressed as 5/4. If d2 is a repeating decimal, it can be expressed as an infinite series of the form:

d2 = a + b/10 + c/100 + ...

where a, b, c, etc. are digits. We can express this as a fraction by multiplying both sides by a power of 10 which eliminates the repeating decimal. For example, if d2 = 0.666..., we can multiply both sides by 100 to get:

100d2 = 66.666...

Subtracting d2 from both sides, we get:

99d2 = 66

So, d2 = 66/99, which can be simplified to 2/3.

Substituting these values into the formula for the area of the rhombus, we get:

[tex]A = (1/2)(5/4)(2/3)\\= 5/12[/tex]

So, the area of the rhombus is a rational number, specifically 5/12, which can be expressed as a fraction. Therefore, we can conclude that when d1 is a terminating decimal and d2 is a repeating decimal, the area of the rhombus can be expressed as a rational number.

Answer:

11:45 AM

Step-by-step explanation:

We have that in one hour the body temperature decreased

went down in

81.7 - 80.2 = 1.2

i.e. 1.2 degrees.

Normal body temperature is 98.6 degrees.

The difference between normal and 11 pm is 98.6-81.7 = 16.9

i.e. 16.9 degrees

now to know how much it decreases every hour:

16.9/ 1.5 = 11.26, that is 11 hours and 15 minutes (1/4 of an hour)

If that was 11:00 PM - 11:15 minutes, the murder was at 11:45 AM

Final answer:

To determine the time of death using body temperature changes from normal to discovered levels, applying physics principles is essential.

Explanation:

The time of death for the old man can be determined by calculating the rate at which body temperature decreases from the normal level to the discovered level. In this case, we have a normal body temperature of 37°C, a discovered temperature of 28°C, and subsequent temperatures of 24°C and 0°C. Using the information provided, the time of death for the old man was approximately 10:00 PM.

This calculation is based on the rate of body temperature decrease from the point of discovery to the hospital, considering the normal body temperature, room temperature, and the temperatures recorded during the investigation. This scenario demonstrates the application of physics principles in forensic investigations to determine the time of death based on body temperature changes.

Answer:

[tex]64\pi[/tex]

Step-by-step explanation:

The area of a circle can be found using:

[tex]a=\pi r^{2}[/tex]

We have the circumference, but we need the radius. Circumference can be found using:

[tex]c=2\pi r[/tex]

We know the circumference is 16[tex]\pi[/tex], so we can substitute that in for c

16[tex]\pi[/tex] =2[tex]\pi[/tex] r

We need to solve for r, or the radius. To do this, divide both sides by 2[tex]\pi[/tex]. This will get r by itself.

16[tex]\pi[/tex] /2[tex]\pi[/tex] =2[tex]\pi[/tex] r/2[tex]\pi[/tex]  

8=r

Now we know the radius, and can substitute it into the area formula

[tex]a=\pi r^2[/tex]

Substitute 8 in for r

[tex]a=\pi 8^2[/tex]

[tex]a=64\pi[/tex]

This answer is expressed in terms of pi, since it includes pi in the answer. Therefore, the area, in terms of pi is [tex]64\pi[/tex]
