Answer:

The Mean is 3

Step-by-step explanation:

For future reference, here's how to solve the mean.

1.Add up all data values to get the sum

2.Count the number of values in your data set  and divide the sum by that number.

In this problem, there are 5 values, and all the values added together equals 15. Divide 15 by 5 and you get 3. The mean is 3.

Answer:

all the values

Step-by-step explanation:

[tex]-8(-x-5)=40+8x\\\\-x-5=\frac{40}{-8}+ \frac{8x}{-8} \\\\-x-5=-5-x\\\\-x-5=-x-5\\\\-x=-x-5+5\\\\-x=-x+0\\\\-x=-x\\[/tex]

[tex]-1(-x)=-1(-x)\\\\x=x[/tex]

so all the values for x are solutions

Answer:

40=40 so the equation is true

Step-by-step explanation:

-8(-x-5)=40+8x

8x +40 = 40 + 8x

if you cancle out the 8x on both sides then it will be 40 = 40

therefore the equation is true and have infinite soulutions

Given:

The polynomial is

[tex]14x^{19}-9x^{15}+11x^4+5x^2+3[/tex]

To find:

One term which is used to add in given polynomial to make it into a 22nd degree polynomial.

Solution:

Degree of a polynomial is the highest power of the variable.

Let,

[tex]P(x)=14x^{19}-9x^{15}+11x^4+5x^2+3[/tex]

Here, the highest power of x is 19, so degree of polynomial is 19.

To make it into a 22nd degree polynomial, we need to need a term having 22 as power of x.

We can add [tex]kx^{22}[/tex], where k is constant.

So add [tex]x^{22}[/tex] in the given polynomial.

[tex]P(x)=x^22+14x^{19}-9x^{15}+11x^4+5x^2+3[/tex]

Now, the degree of polynomial is 22.

Therefore, the required term is [tex]x^{22}[/tex].

The required polynomial to a 22nd degree is [tex]P(x)=x^{22}+14x^{19} - 9x^{15} + 11x^4 + 5x^2[/tex]

Given the polynomial function, [tex]14x^{19} - 9x^{15} + 11x^4 + 5x^2[/tex],, we are to add one term to the polynomial to make it into a 22nd-degree polynomial.

Note the highest and leading power of the variable of any function is the degree of such function.

To convert the given polynomial to a 22nd-degree function, we will simply add a variable term x with a degree of 22 to have:

[tex]P(x)=x^{22}+14x^{19} - 9x^{15} + 11x^4 + 5x^2[/tex]

Hence the required polynomial to a 22nd degree is [tex]P(x)=x^{22}+14x^{19} - 9x^{15} + 11x^4 + 5x^2[/tex]

Answer:

Undeterminable, as no answer choices are given.

Step-by-step explanation:

No answer choices have been given. However, you can always find this out. Rational numbers are always a fraction or repeating decimal. For example, 1/3 is rational, 2.3838383838 is rational, but 3.1415926535879 is irrational.

Answer:

$12

Step-by-step explanation:

First you make an equation-

Since she spent half of her allowance at the movies it should start with x/2. Then you add the extra money she made. This should equal $14.

Equation: x/2 + 8 = 14

Solve

x/2 + 8 = 14

Subtract 8 from both sides

x/2 = 6

Multiply each side by 2.

x= 12

6.34 where 4 is repeating is rational no. because all the nos. which have repeating and terminating decimals can be rationalised.

An irrational no. is a number which has non repeating and non terminating decimal part.

According to the given question 6.34 the 4 repeating rational or irrational.

6.34 where 4 is repeating can be written as

6.3[tex]\overline{4}[/tex] to write this decimal in fractional form we write 6 + (9's for every repeating digit and 0 for every non repeating digit in the denominator and we subtract the non repeating part from the whole decimal part).

∴ 6.3[tex]\overline{4}[/tex] can be written as 6 + (34-3)/90 which is

= 6 + 31/90

= (540 + 31)/90

= 571/90.

23/18

Step-by-step explanation:

Answer:

23/18 or 1 and 5/18

Step-by-step explanation:

7/9+1/2 can't be directly added, so you must find the lowest-common-denominator, which is 18 (multiplying the denominators gets you this number.) You then change the factors to have the common denominator of 18, which would be 14/18 and 9/18. From here, you just simply add those two numbers together.

Answer:

36 units squared

Step-by-step explanation:

Let's say that (1, 13) is point A, (7, 13) is B, (7, 1) is C, and (1, 1) is D. The distance from point A to point B is 6 units horizontally, which we now know is the base. The distance from point C to point D is 6 units vertically, so this must be the height of the shape. To find the area we multiply the base times the height (6 * 6). We get 36, so the area of this shape is 36 units squared.

Answer:

Well n=6

Step-by-step explanation:

This is because if 0=m you put that in the spot were m is and then that would be 0/5 which is 0 than you add 6 which 0+6 = well 6. Then you just plug your x's in to the equation (second part) but if you don't have a x you plug the y in instead.

Answer:

x = - [tex]\frac{80}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{7}[/tex] - [tex]\frac{2}{5}[/tex] x = 5

Multiply through by 35 ( the lcm of 7 and 5 ) to clear the fractions

15 - 14x = 175 ( subtract 15 from both sides )

- 14x = 160 ( divide both sides by - 14 )

x = [tex]\frac{160}{-14}[/tex] = - [tex]\frac{80}{7}[/tex]  

Given :

[tex]C(\dfrac{5}{3},-6)\ , \ B(\dfrac{8}{3},4)[/tex] .

B is the mid-point of AC .

To Find :

The missing endpoint if B is the midpoint of AC.

Solution :

Let , coordinate of point A is ( h, k) .

So , mid-point B is given by :

[tex](\dfrac{\dfrac{5}{3}+h}{2},\dfrac{-6+k}{2})[/tex]

Comparing above point with [tex]B(\dfrac{8}{3},4)[/tex] , we get :

[tex]\dfrac{\dfrac{5}{3}+h}{2}=\dfrac{8}{3}\\\\h+\dfrac{5}{3}=\dfrac{16}{3}\\\\h=\dfrac{11}{3}[/tex]        [tex]\dfrac{-6+k}{2}=4\\\\k=14[/tex]

Therefore , the value of point A is [tex](\dfrac{11}{3},14)[/tex] .

Hence , this is the required solution .
