Answer:

Step-by-step explanation

Let the number be y

y doubled = y×2=2y

2y increases by 3 = 2y+3=

2y +3 is more than 6 but less than 20

2y+3 > 6

2y+3< 20

Solve for y

2y>6-3

y>3/2

2y+3<20

2y<20-3

2y<17

y<17/2

Ys is the perpendicular bisector of xz. What is the length of Xs if xz is 18 inches long?
exis [7]

Answer:

XS is 9 inches long.

Step-by-step explanation:

Given that

YS is the perpendicular bisector of XZ.

Length of XZ = 18 inches

To find:

Length of XS = ?

Solution:

First of all, let us learn about the perpendicular bisector.

Perpendicular bisector of a line <em>AB</em> is a line <em>PQ</em>, which divides the line AB in two equal parts and is at an angle of 90^\circ with the line AB.

If B is on the line PQ, then BP = BQ = \frac{PQ}{2} and

\angle ABP = \angle ABQ = 90^\circ

Applying the above property in our given question.

Kindly refer to the attached image for the given dimensions.

S is on the line XZ.

XS = SZ = \frac{XY}{2} = \dfrac{18}{2} \\\Rightarrow \bold{XS = 9\ inches}

So, the answer is XS is 9 inches long.

Which data set does the histogram represent?
MAVERICK [17]

Answer/Step-by-step explanation:

Ok so there is

3, 0-4                  4, 5-9                2, 10-14             1, 15-19       1, 20-24

so you can get rid of the last one saying it has more than 1 number between 20-24.

The 3rd one has to short of numbers for 0-4.

the second one has way to many 0-4's when there should be 3 of them.

therefore your answer is The firstone.
