Step-by-step explanation: 23 is the median of the data set because it's the number in the middle.  

Median: 16, 18, 19,23, 24, 31, 32  

Mean: 16+18+19+23+24+31+32= 163 then divide by how many numbers you added by 163 divided by 7 equals 23.28571429. I'll just simplify it to 23.29 or rounding to tenths 23.3.

Answer:

Median = 23

Mean = 163/7 = 23.3 (1 d.p.)

Step-by-step explanation:

Given data set:

19, 18, 23, 24, 31, 32, 16

The middle value when all data values are placed in order of size.

Given data values in size order, from smallest to largest:

[tex]\sf 16, 18, 19, \boxed{\sf 23}, 24, 31, 32[/tex]

The middle value is 23, so the median of this data set is 23.

The sum of all data values divided by the total number of data values.

[tex]\begin{aligned}\implies \sf mean & =\sf \dfrac{19+18+23+24+31+32+16}{7}\\& = \sf \dfrac{163}{7}\\ & = \sf 23.28571429...\\ & = \sf 23.3\:(1\:d.p.)\end{aligned}[/tex]

Answer: x∈[0;+∞)

Step-by-step explanation:

[tex]|x|-6 > -16\\|x|-6+6 > -16+6\\|x| > -10\\[/tex]

From the information given, the value of b if YH = 12b - 4.5, MV = 17b +0.75, and MW-WH = 13.25 is 0. 59

Algebraic expressions are simplify defined as expressions that are composed of terms, variable, coefficients, factors and also constants.

They also seen as expressions involving arithmetic operations such as;

From the information given, we have that;

MW-WH = 13.25.

Where;

Now, to determine the value of b, substitute the values into the equation

17b +0.75 + 12b - 4.5 = 13. 25

collect like terms

17b + 12b = 13.25 + 4. 5 - 0. 75

add or subtract like terms

29b = 17

Make 'b' the subject of formula by dividing both sides by 29, we have;

29b/29 = 17/29

Divide through

b = 0. 59

Thus, the value of b is 0. 59

The midpoint of diagonal AC is (5,-3).

Given A(3,-1) and C(7,-5)

Let the midpoint of diagonal AC be represented by P (say). Then the coordinate of P can be calculated by using the formula listed below:

let us suppose the coordinates of A be (a, b) and B be (c, d) and P is the midpoint of AC then the coordinate of P will be (a+c/2, b+d/2).

Now, by using the above formula, we get

The measure of angles 1, 2 and 3 for fig in 11. are 100°, 80° and 100°. And for part 12. are 80°, 80° and 100° respectively.

For 11. part:

Considering two parallel lines l and m cut by a transversal p,

If two parallel lines are intersected by a transversal, each pair of interior angles on the same side of the transversal is supplementary.

m∠1 + 80° = 180°

m∠1 = 180° - 80°

m∠1 = 100°

Similarly, m∠1 + m∠2 = 180°

⇒ 100° + m∠2 = 180°

⇒m∠2 = 180° - 100°

⇒m∠2 = 80°

and also, m∠2 + m∠3 = 180°

⇒ 80° + m∠3 = 180°

⇒m∠3 = 180° - 80°

⇒m∠3 = 100°

Therefore, m∠1 = 100°, m∠2 = 80° and m∠3 = 100°.

For 13. part:

m∠3 = 100° (vertically opposite angle)

Now, let us suppose the angle adjacent to ∠3 be x then, m∠x will be simply equal to

m∠3 + m ∠x = 180° (Linear pair property.)

100° + m ∠x = 180°

m ∠x = 180° - 100°

m ∠x = 80°

Now, from the figure we can clearly see that,

m∠1 = m∠2 = m ∠x  = 80°(Corresponding angles are equal.)

Answer:

30 c + 100 m = 700

c+ m = 14

Step-by-step explanation:

The product of the number of movies where the song was played (m) multiplied by the earnings per movie (30) plus the product of the number of commercials where the song was played (m) multiplied by the earnings per commercial, must be equal to $700.

30 c + 100 m = 700

The number of movies (m) plus the number of commercials (c) is equal to 14.

c+ m = 14

The relation that is not a function, but whose inverse is a function are:

for every x in the domain of f, f -1[f(x)] = x, and

for every x in the domain of f -1, f[f -1(x)] = x

An inverse function is a characteristic that undoes the movement of another characteristic. A feature g is the inverse of a characteristic f if whenever y=f(x) then x=g(y). In different words, applying f and then g is the equal aspect as doing not anything. we are able to write this in terms of the composition of f and g as g(f(x))=x.

A few capabilities do not have inverse functions. for instance, remember f(x) = x2. There are numbers that f takes to four, f(2) = 4 and f(-2) = four. If f had an inverse, then the fact that f(2) = 4 might mean that the inverse of f takes four again to 2.

To discover the inverse function of an algebraic relation in terms of x and y, simply interchange the variables x and y, and resolve the equation for y. as an example, to discover the inverse of a relation y = x3, interchange x, and y after which clear up it for y. Then we get x = y3 ⇒ y = x1/3.

An inverse version can be represented by means of the equation xy=k or y=kx. this is, y varies inversely as x if there are a few nonzero steady k such that, xy=k or y=kx in which x≠0,y≠0 . assume y varies inversely as x such that xy=3 or y=3x.

The net force is the sum of all of the forces exerted on an object.

Identifying Forces

Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.

Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.

Net Force

As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.

On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.
