Answer:

Step-by-step explanation:

The middle 50% of the data is represented by the box.

The range is the difference between the upper value and the lower value

upper value = 7 and lower value = 4

Range = 7 - 4 = 3

Answer: 3

Step-by-step explanation:

We know that the interquartile range is known as the range of the middle 50% of the data.

Interquartile range is the difference between the third quartile and first quartile.

From the given box plot , the first quartile ( where box starts ) $Q_1= 4$

The third quartile ( where box ends ) $Q_3= 7$

Then, the interquartile range = $Q_3-Q_1= 7-4=3$

Thus , the range of the middle 50% of the data =3

Arturiano [62]

The answer is always all the numbers added together
with the what they are specifically asking in front.
if that makes sense?

3:14

they are asking for the red so 3 goes in front and the total number of all the paper clips follows

one interior angle of a polygon is equal to 800 and each of the other interior angles are 128 degrees. Find the number of sides

KiRa [710]

Answer:

Step-by-step explanation:

Given information:

Interior angle of a polygon cannot be more that 180°.

One interior angle = $80^{\circ}$

Other interior angles are = $128^{\circ}$

Let n be the number of sides of the polygon.

Sum of interior angles is

$Sum=80+128(n-1)$

$Sum=80+128n-128$

Combine like terms.

$Sum=128n-48$ .... (1)

If a polygon have n sides then the sum of interior angles is

$Sum=(n-2)180$

$Sum=180n-360$ .... (2)

Equating (1) and (2) we get

$180n-360=128n-48$

Isolate variable terms.

$180n-128n=360-48$

$52n=312$

Divide both sides by 52.

$n=\frac{312}{52}$

$n=6$

Therefore the number of sides of the polygon is 6.

4. A 25-foot ladder is placed against the side of a building with the bottom of the ladder 7 feet from the

faltersainse [42]

Answer:

Step-by-step explanation:

The questions asks for how far down the wall does the ladder move, so to say that in another way, what is the difference between when the ladder is taller up the wall and when it is shorter up the wall.

so figure out what the height of the ladder is up the wall for each of the situations.

1) Taller

we are told the Hyp and the Adj sides of the triangle

so use SOH CAH TOA to remind how trig functions fit on the triangle sin = Opp / Hyp , Cos=Adj / Hyp , Tan = Opp / Adj so

Cos(Ф) = 7 / 25

Ф = arcCos( 7/25)

Ф = 73.739795 °

then use

Sin( 73.739795 ) = Opp / 25

25* Sin( 73.739795 ) = Opp

24 = Opp

2) Shorter

Cos(Ф) = 15 / 25

Ф = arcCos( 15 / 25 )

Ф = 53.13010 °

sin( 53.13010 ) = Opp / 25

25 * sin( 53.13010 ) = Opp

20 = Opp

now you know the two heights up the wall. so subtract the shorter from the taller

24 - 20 = 4

the ladder moves 4 feel down the wall :)
