Step-by-step explanation:

The position of the median of an even data set is 1/2(8+1)=4.5

That is between two values, 4 and 5.

(5x-10+3x+30)/2=82

(8x+20)/2=82

(8x+20)=41

8x=41-20

8x=21

x=21/8

Answer:

54

Step-by-step explanation:

the 2 lines are parallel and the line going through is a transversal.

because of vertical angles, the x+3 is equal to the angle diagonal to it.

that diagonal angle is equal to the top right one (57˚) by same side interior angle thereom. So intern, x+3 = 57

x = 54

Answer:

4!

Step-by-step explanation:

In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.

So, we have to put vowels at each even position; only then the condition will be satisfied.

We can put this in 3! ways (permutations of A, I & U).  

For odd positions we can put 3-M's & a X. Total ways is 4!/3!   (as repetitions of M).

Hence, the answer is 4!/3! x 3! = 24 ways.  

24=4!.

I think this should be the answer

Step-by-step explanation:

3.28 - 1.97

Answer:

Step-by-step explanation:

1985:

x = 5 years  ( 1980 to 1985- 5 years)

0.142x + 1.93 = 0.142*5 + 1.93

                     = 0.71 + 1.93

                     = $ 2.64

1999:

x = 19 years

0.142x + 1.93 = 0.142*19+ 1.93

                     = 2.698 + 1.93

                     =4.628 =  $ 4.63

2010:

x = 30 years

0.142x + 1.93 = 0.142*30 + 1.93

                     =  4.26 + 1.93

                     = $ 6.19

p=70°

q=32°

r=38°

Answer:

Solution given:

r=38°[inscribed angle on a same arc are equal]

p=½*140°=70°[inscribed angle is half of the central angle]

<OBA=38°[base angle of isosceles triangle]

again

<C=<B[inscribed angle is half of the central angle]

70°=<OBA+q

70°=38°+q

q=70°-38°

q=32°

Answer:

(A) Over the interval [-2.5, 0.5], the local maximum is 2.

Step-by-step explanation:

"Over the interval [-2.5, 0.5], the local maximum is 2."

Correct. The local maximum is the maximum, or highest point, of the graph in a certain area of interval. In [-2.5, 0.5], the highest point is at the y-value of 2.

"As the x-values go to positive infinity, the function's values go to negative infinity."

Wrong. As the x values go to positive infinity (meaning they go to the right, or positive side of the graph), the function goes up, meaning the function's values go to positive infinity.

"The function is decreasing over the interval (-1, 0.75)."

Wrong. Only from [-1, 0] is where that area of the graph decreases. The other half of it, (0, 0.75), is where the graph increases.

"The function is negative for the interval [-2, 0]."

Wrong. Only from [-1, 0] is the function negative. In the interval [-2, -1], the function is positive.

(4+7)^2=11^2=121

2^3=8

121+8=129

Answer:

= 121

Step-by-step explanation:

it's algebra questions. in Algebra there are some formula are necessary to remember.

(4+7)²+2³

> (4²+2×4×7+7²)+2×2×2×2

> (4×4+2×4×7+7×7)+16

> 8 +56+49+16

> 129

• Equation (4+7)²+2³ is equal to 129.

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is option C.

Answer:

from what I know I think the answer is D_24

Answer:

The friend's answer is incorrect.

The correct answer is:

[tex] \dfrac{3(x - 1)}{x + 2} [/tex]

Step-by-step explanation:

[tex] \dfrac{x^2 - 1}{x^2 - 4x - 5} \div \dfrac{2x^2 + 4x}{6x^2 - 30x} = [/tex]

To divide by a fraction, multiply by its reciprocal.

[tex] = \dfrac{x^2 - 1}{x^2 - 4x - 5} \times \dfrac{6x^2 - 30x}{2x^2 + 4x} [/tex]

Multiply the numerators together. Multiply the denominators together.

[tex] = \dfrac{(x^2 - 1)(6x^2 - 30x)}{(x^2 - 4x - 5)(2x^2 + 4x)} [/tex]

Factor every polynomial.

[tex] = \dfrac{(x - 1)(x + 1)(6x)(x - 5)}{(x - 5)(x + 1)(2x)(x + 2)} [/tex]

Divide the numerator and denominator by the common terms.

[tex] = \dfrac{(x - 1)(6)}{(2)(x + 2)} [/tex]

[tex] = \dfrac{3(x - 1)}{x + 2} [/tex]

The friend's answer is incorrect.

The correct answer is:

[tex] \dfrac{3(x - 1)}{x + 2} [/tex]

3 : 2

bc :

3*15 = 45

2*15 = 30

Answer: 2/3

Step-by-step explanation: 30÷5; 45÷5= 6/9=2/3

Step-by-step explanation:

x=y³/z

(y³/z) to the power of a = y to the power of b

[tex] {y}^{3a} \div {z}^{a} = {y}^{b} [/tex]

[tex] {y}^{3} \div z = {y}^{b \div a} [/tex]

[tex] {y}^{3 \div b} \div {z}^{1 \div b} = {y}^{1 \div a} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} {z}^{1 \div b} [/tex]

[tex] {y}^{b} = {z}^{c} [/tex]

[tex]z = {y}^{b \div c} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} \times ({y^{b \div c} })^{1 \div b} [/tex]

[tex] {y}^{3 \div b} = {y}^{1 \div a} \times {y}^{1 \div c} [/tex]

as b/c × 1/b = 1/c

and so we see based on the exponents that

3/b = 1/a + 1/c

Answer:  108cm%2F%222+cm%22=54 .

Then you would add more rows like that for a total of

72cm%2F%222+cm%22=36 rows.

Step-by-step explanation:

many 2cm by 2cm square can be used to cover the rectangle without any spaces or overlapping.

It is possible because 72 and 108 are both divisible by 2.

You can start by lining up in row 54 such 2cm by 2cm squares along with one of the 108cm long sides,

Answer:

13/36

Step-by-step explanation:

1 - 2/3 equals 1/3 which is inside the parenthesis

square the number in parenthesis (1/3) and it equals 1/9

multiply the 2 fractions 1/4 and 1/9 to get 1/36

finally add 1/3 with 1/36

12/36 + 1/36 would equal 13/36
