Answer:

x = 5

Step-by-step explanation:

2x = 10

2 multiply with x = 10

10 turn divided by 2 so

x = 10/2

x = 5

The data set represents the number of rings each person in a room is wearing.
MrRa [10]
If the data set represents the number of rings each person is wearing, being: 0,2,4,0,2,3,2,8,6, the interquartile range of the data is 2. Being, 4 as the Q1, 3 as the Q2 or median, and 6 as the Q3. Where the formula of getting the interquartile range is IQR= Q1-Q2.

What is the simplest form of square root of
AveGali [126]

First step is to simplify the inside of the radical. There are x's on both top and bottom of the fraction. So we subtract their exponents. x³ - x¹ = x². Because the x³ was in the denominator and it was bigger, the x² goes on the bottom.

Your new equation is:

\sqrt{\frac{126y^{5}}{32x^{2}}   }

Now, I'd suggest factoring each term to correspond with the square root.

126y⁵ = 9 · 14 · y² · y² · y

32x² = 4 · 4 · 2 · x²

9, y², and y² can be square rooted in the numerator. 4, 4, and x² in the denominator. So we pull out their square roots and place them outside of the radical. The rest stays in the radical:

\frac{3 * y * y}{2*2*x}\sqrt{\frac{14y}{2}}

Simplify to get your final answer:

\frac{3y^{2}}{4x} \sqrt{7y}

It's easier to explain on paper and in person than over computer text, sadly. Hopefully you can follow along with this.

Factor x^4 - 2x^3 - 33x^2 + 50x + 200 completely using the given factor x^2 - 25.
PIT_PIT [208]

You can do synthetic division twice immediately (or once if you know how to handle x^2 - 25 all at once. I'll use 2 divisions. x^2 - 25 is (x + 5)(x - 5). Both of them are zeros to the given equation which means that x = +5 and

x = - 5  are both zeros of the given quartic.

5        1      -2       -33       50         200

                 5         15       -90         -200          

=====================================

          1       3        -18       -40         0

What you have now is x^3 + 3x^2 - 18x - 40 = 0

Do another synthetic division

-5        1       3       -18       -40

                   -5       10        40

============================

           1      -2        -8        0

The result is

x^2 - 2x - 8 = 0 which factors.

(x + 2)(x - 4) = 0

Answer

The factors are (x + 2)(x - 4)(x + 5)(x - 5) = 0

Long division

x^2 + 0 + 25 ||x^4 - 2x^3 - 33x^2 + 50x + 200 ||x^2 - 2x - 8

                      x^4 + 0  +    25x^2

                      ==================

                               -2x^3 -8x^2  +  50x

                                -2x^3 + 0  +     50x

                                =================

                                            -8x^2 + 0 +200

                                            -8x^2 + 0 + 200

                                ==================
