Answer:

Range and interquartile range

Step-by-step explanation:

Range is the difference between the highest and lowest values.

Interquartile range is a measure of statistical dispersion, being equal to the difference between 75th and 25th percentiles, or between upper and lower quartiles, IQR = Q₃ − Q₁.

Answer:

True.

Step-by-step explanation:

It says to work out what is in parentheses first, (PEMDAS).

For example:

2(5 - 3) - 1    

5 - 3 = 2 so we have:

2 * 2 - 1

= 4 - 1

= 3.

Answer:

The measure of the arc CD = 64°

Step-by-step explanation:

It is required to find the measure of the arc CD in degrees.

So, as shown at the graph

BE and AD are are diameters of circle P

And ∠APE is a right angle ⇒ ∠APE = 90°

So, BE⊥AD

And so, ∠BPE = 90° ⇒(1)

But it is given: ∠BPE = (33k-9)° ⇒(2)

From (1) and (2)

∴ 33k - 9 = 90

∴ 33k = 90 + 9 = 99

∴ k = 99/33 = 3

The measure of the arc CD = ∠CPD = 20k + 4

By substitution with k

∴ The measure of the arc CD = 20*3 + 4 = 60 + 4 = 64°

Answer:

x - 2y - 7 = 0

Step-by-step explanation:

To find the equation of a line that passes through (-5, -3) and (3,1)

All we need to do is to use the find the slope and then plug it into the straight line equation

straight line equation :   y -  [tex]y_{1}[/tex]   =   m (x  -  [tex]x_{1}[/tex])

[tex]x_{1}[/tex] = -5     [tex]y_{1}[/tex] = -3   [tex]x_{2}[/tex] = 3   [tex]y_{2}[/tex] = 1

m = slope =  [tex]y_{2}[/tex]  -  [tex]y_{1}[/tex]   /  [tex]x_{2}[/tex]  -  [tex]x_{1}[/tex]

                =   1 -(-3)  /   3 -(-5)

                 =4/8

                  =1/2

m=1/2

So, we can now plug in our value into  the equation;

y  -  [tex]y_{1}[/tex]   =   m (x -  [tex]x_{1}[/tex])

y - (-5) = [tex]\frac{1}{2}[/tex] [x - (-3)]

y + 5 = [tex]\frac{1}{2}[/tex](x+3)

y +  5  =  [tex]\frac{x + 3}{2}[/tex]

cross-multiply

2(y + 5) =   x + 3

2y + 10  =  x + 3

take 2y and 10 to the right-hand side of the equation;

x + 3 - 2y - 10  = 0

x - 2y - 7 = 0

Therefore the equation of the line is x - 2y - 7 = 0

Answer:

(2,2) is not a solution of the system.

Step-by-step explanation:

Given : Equations [tex]5x-9y\geq 8[/tex] and [tex]7x-4y<10[/tex].

To find : Is (2,2) a solution of the system?

Solution :

To know that the given point is the solution or not we have to put the values in equation if inequality is true then the point is the solution.

Substitute (2,2) in [tex]5x-9y\geq 8[/tex] ,

[tex]5(2)-9(2)\geq 8[/tex]

[tex]10-18\geq 8[/tex]

[tex]-8\geq 8[/tex]

It is not true.

Substitute (2,2) in [tex]7x-4y<10[/tex] ,

[tex]7(2)-4(2)<10[/tex]

[tex]14-8<10[/tex]

[tex]6<10[/tex]

It is true.

So, (2,2) is not a solution of the system.

Answer:

Two solutions were found :

x = 6

x = -1

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (3x2 -  15x) -  18  = 0  

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  3x2 - 15x - 18  =   3 • (x2 - 5x - 6)  

Trying to factor by splitting the middle term

3.2     Factoring  x2 - 5x - 6  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  -6  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -6 = -6  

Step-2 : Find two factors of  -6  whose sum equals the coefficient of the middle term, which is   -5 .

     -6    +    1    =    -5    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -6  and  1  

                    x2 - 6x + 1x - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-6)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-6)

Step-5 : Add up the four terms of step 4 :

                   (x+1)  •  (x-6)

            Which is the desired factorization

Equation at the end of step  3  :

 3 • (x + 1) • (x - 6)  = 0

In Conclusion, the answer would be 0.

Answer:

∠ K = 35° and ∠ L = 105°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let ∠ K = x then ∠ L = 3x

Sum the angles and equate to 180

3x + x + 40 = 180, that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

Thus

∠ K = 35° and ∠ K = 3x = 3 × 35 = 105°

Step-by-step explanation:

Answer:

x = 5.

Step-by-step explanation:

3x +5 = 20

Subtract 5 from both sides:

3x + 5 - 5 = 20 - 5

3x = 15

Divide both sides by 3:

x = 15/3

x = 5.

Answer:

Step-by-step explanation:

D.The left end goes up and the right end goes down because this is a first order function

The end behavior of the function f(x) = -2(x - 2)^5 is that the left end goes up and the right end goes down. This is determined by the odd degree and negative leading coefficient of the function.

The end behaviors of a function can be determined by looking at the highest degree term, also known as the leading term. In this case, for the function f(x) = -2(x - 2)^5, the highest degree is odd (5), and the coefficient, -2, is negative.

Odd degree with a negative leading coefficient means that the end behaviors of this function will be: as x approaches negative infinity (moves left), the function values will go toward positive infinity (up), and as x approaches positive infinity (moves right), the function values will go toward negative infinity (down).

So the correct option here is: D. The left end goes up; the right end goes down.

Step-by-step explanation:

We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.

[tex]-3x+(A)x=2x[/tex]

We can simplify the equation if we add 3x to both sides, which then leaves us with this.

[tex](A)x=5x[/tex]

We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.

[tex]A=5[/tex]

Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.

[tex](x+1)(2x^{2}-3x+5)[/tex]

If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.

y = kx/z

When y =520

x = 5

z = 6.5

K =?

We have

520 = k x 5/6.5

Cross multiply

520 x 6.5 = 5k

3380 = 5k

Divide both sides by 5

3380/5 = 5k/5

676 = k

k = 676

Answer:

$13.14

Step-by-step explanation:

60 mi/1 hour = x mi/1.5 hours

x = 90 mi to drive to work

25 mi/1 gallon = 90 mi/y gallons

y = 3.6 gallons to get to work

$3.65/1 gallon = $z/3.6 gallons

z = $13.14

Justin spends $13.14 on gas to get to work.

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The average speed of Justin when he goes to work is 60 miles/hour.

The time taken to reach to work is 1 hour 30 minutes.

Justin's car travels 25 miles for 1 gallon of gas.

The cost for one gallon of gas is $3.65 per gallon.

The total miles travelled is 60 miles/ hour * 1 hour 30 minutes.

Total miles travelled = 60 * (1.5)

Total miles travelled = 90 miles

The gas used for 25 miles is 1 gallon

The gas used for 90 miles is 90/25 = 3.6 gallon.

The cost of gas is $3.65 per gallon

The cost of 3.6 gallon is 3.65 *3.65

The cost of the gas used to get to work is $13.14.
