Answer: 10

<u>Step-by-step explanation:</u>

\text{Younger sister:}\ \dfrac{1}{2}x + 2

Older sister: x


Younger + Older = 26

\dfrac{1}{2}x + 2 + x = 26

x + 4 + 2x = 52   <em>multiplied everything by 2 to clear the denominator</em>

3x + 4 = 52      <em>added like terms</em>    

3x       = 48      <em>subtracted 4 from both sides </em>

 x       = 16       <em>divided both sides by 3</em>


\text{Younger sister:}\ \dfrac{1}{2}x + 2 = \dfrac{1}{2}(16) + 2 = 8 + 2 = 10

If a distribution for a quantitative variable is thought to be nearly symmetric with very little variation,and a box and whisker
marusya05 [52]

Answer:

B). The left and right-hand edges of the box will be approximately equal distances from the median.

Step-by-step explanation:

The 'symmetry' si described as a 'satisfying arrangement of a balanced distribution of the elements of the whole' while a 'symmetry group' is characterized as a group whose elements are all the transformations under which a given object remains invariant and whose group operation is function composition.

As per the given conditions, <u>the second statement asserts a true claim regarding the keeping of edges of left, as well as, right-hand side's boxes at equal intervals from the median</u>. This will help in making the arrangement fulfilling while keeping a little scope for the variation. Thus, <u>option B</u> is the correct answer.

Help me! Answer in pic not correct !
sladkih [1.3K]

Answer:

Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)

Step-by-step explanation:

First we have to find the coordinates of the original ordered pairs then we will do the translation.

Q=(1,3)\\R=(3,-3)\\S=(0,-2)\\T=(-2,1)

Now we will add 3 to every x value and add a -2 to every y value.

Q=(1_{+3},3_{+(-2)})\\R=(3_{+3},-3_{+(-2)})\\S=(0_{+3},-2_{+(-2)})\\T=(-2_{+3},1_{+(-2)})

When you do that you will get the new prime points.

Q'=(4,1)\\R'=(6,-5)\\S'=(3,-4)\\T'=(1,-1)
